Anemia is a condition that develops when your blood lacks enough healthy red blood cells or hemoglobin. Hemoglobin is a main part of red blood cells and binds oxygen. If you have too few or abnormal red blood cells, or your hemoglobin is abnormal or low, the cells in your body will not get enough oxygen.

Anemia is defined as a hemoglobin below two standard deviations of the mean for the age and gender of the patient. Iron is an essential component of the hemoglobin molecule. The most common cause of anemia worldwide is an iron deficiency, which results in microcytic and hypochromic red cells on the peripheral smear. Several causes of iron deficiency vary based on age, gender, and socioeconomic status. The patient often will have nonspecific complaints such as fatigue and dyspnea on exertion. Treatment is a reversal of the underlying condition as well as iron supplementation. Iron supplementation is most often oral, but certain cases may require intravenous iron. Patients with iron-deficient anemia have been found to have a longer hospital stay along with a higher number of adverse events.,,

Anemia occurs when either the number of red blood cells (RBCs) is too low or the hemoglobin within those cells is deficient. Hemoglobin is the protein that binds oxygen in the lungs and delivers it throughout the body. When hemoglobin levels drop below normal, tissues receive less oxygen and can’t function properly. Clinically, anemia is diagnosed when hemoglobin falls below 13.0 g/dL in men or below 12.0 g/dL in women. The condition can range from mild—where symptoms may be barely noticeable—to severe, which can cause chest pain, shortness of breath, and organ damage if left untreated.

Anemia is defined as a condition in which the number of red blood cells or the hemoglobin concentration within them is lower than normal, resulting in a reduced capacity of the blood to carry oxygen to the body’s tissues. Hemoglobin, the iron-rich protein in red blood cells, binds oxygen in the lungs and releases it throughout the body; when hemoglobin levels fall below established cut-off points, tissues receive inadequate oxygen, leading to fatigue, weakness, dizziness, and shortness of breath World Health OrganizationWorld Health Organization. The World Health Organization (WHO) specifies different hemoglobin thresholds depending on age, sex, and physiological status: at sea level, anemia is diagnosed when hemoglobin is below 130 g/L in adult men, below 120 g/L in nonpregnant women, and below 110 g/L in pregnant women and children under five World Health Organization. Anemia’s impact ranges from impaired cognitive and physical development in children to increased maternal mortality and reduced work capacity in adults, making it a major global public health concern.

Normal Hb-specific laboratory cut-offs will differ slightly, but in general, the normal ranges are as follows:

  • 135 to 180 g/L in men
  • 120 to 150 g/L in women
  • 110 to 160 g/L in children
  • Varied in pregnancy depending on the trimester, but generally greater than 100 g/L

Types of Anemia

Clinicians classify anemia first by RBC size (mean corpuscular volume, MCV), which guides the diagnostic approach:

  • Microcytic Anemia: Characterized by smaller-than-normal RBCs (MCV < 80 fL). It typically results from impaired hemoglobin synthesis, most often due to iron deficiency or thalassemia Healthline.

  • Normocytic Anemia: RBCs are normal in size (MCV 80–100 fL) but reduced in number. Causes include acute blood loss, hemolysis, and anemia of chronic disease Healthline.

  • Macrocytic Anemia: RBCs are larger than normal (MCV > 100 fL) due to defective DNA synthesis, as seen with vitamin B₁₂ or folate deficiencies and certain medications Healthline.

Classification by Underlying Mechanism

  1. Production disorders anemias: occur when the bone marrow fails to make enough red blood cells—examples include aplastic anemia and marrow infiltration.
  2. Destruction (hemolytic) anemias: involve prematurely destroyed red cells, seen in conditions like sickle cell disease or autoimmune hemolysis.
  3. Blood loss anemias: result from chronic bleeding—such as gastrointestinal ulcers or heavy menstruation—depleting red cell mass.
  4. Decreased RBC Production: nutritional deficiencies (iron, B₁₂, folate), bone marrow disorders (aplastic anemia, myelodysplastic syndromes), endocrine causes (chronic kidney disease with reduced erythropoietin), or chronic inflammation.
  5. Increased RBC Destruction (Hemolysis): inherited hemoglobinopathies (sickle cell disease, thalassemia), enzyme deficiencies (G6PD deficiency), immune-mediated hemolysis, and mechanical destruction (prosthetic heart valves). Wikipedia

This morphological classification helps narrow down the underlying mechanism—whether it’s decreased production, increased destruction, or blood loss—and dictates the next steps in evaluation NCBI.

A second functional classification considers the mechanism of anemia:

  • Hypoproliferative Anemia: Bone marrow production is inadequate (e.g., aplastic anemia, renal disease).

  • Hemolytic Anemia: Premature destruction of RBCs exceeds production (e.g., hereditary spherocytosis, autoimmune hemolysis).

  • Hemorrhagic Anemia: Chronic or acute blood loss outpaces RBC replacement (e.g., gastrointestinal bleeding, trauma).

A to Z Types of Anemia

Below are twenty conditions that can lead to low hemoglobin. Each description is in simple language, highlighting how the disease affects Hb levels.

  1. Iron Deficiency Anemia
    Caused by insufficient iron to make hemoglobin, leading to small, pale RBCs. Common in women with heavy periods, children with poor diets, and people losing blood from the gut. Symptoms develop slowly, including fatigue and cold hands. Diagnosis involves CBC and iron studies; treatment is dietary iron and supplements Wikipedia.

  2. Sideroblastic Anemia
    Cells cannot incorporate iron into heme, resulting in ringed sideroblasts visible under a microscope. This may be inherited or acquired from alcohol use, lead poisoning, or certain medications.

  3. Pernicious Anemia
    An autoimmune destruction of stomach cells prevents intrinsic factor production, impairing vitamin B12 absorption. Over time, B12 deficiency leads to macrocytic anemia and neurological signs.

  4. Folate Deficiency Anemia
    Inadequate folate intake or increased requirement—such as during pregnancy—disrupts DNA synthesis in red cell precursors, causing large but few red cells and moderate anemia.

  5. Hemolytic Anemia (Autoimmune)
    The body’s immune system mistakenly attacks its own red cells. Warm or cold antibody variants can cause chronic red cell destruction, leading to moderate anemia and jaundice.

  6. Leishmaniasis
    A parasitic infection that invades bone marrow and spleen, impairing blood cell production and causing moderate anemia along with fever and weight loss.

  7. Aplastic Anemia
    Bone marrow failure leads to reduced production of all blood cells, including RBCs. In mild cases, hemoglobin may dip slightly before pancytopenia develops. Early recognition through blood counts and prompt treatment (immunosuppression or transplant) is crucial Wikipedia.

  8. Pure Red Cell Aplasia (PRCA)
    An isolated failure of RBC production—often immune‑mediated or congenital—causes gradual hemoglobin decline. Other blood lines remain normal. Mild PRCA may present with subtle anemia before transfusion dependence arises Verywell Health.

  9. Anemia Due to Excessive Bleeding
    Acute or chronic hemorrhage (trauma, GI ulcers, menorrhagia) depletes RBC mass faster than marrow can replace them. MSD Manuals
  10. Fanconi Anemia
    A hereditary marrow failure syndrome with DNA repair defects. Patients develop severe anemia in childhood alongside congenital anomalies. Wikipedia An inherited DNA repair disorder causing bone marrow failure and pancytopenia. Presents in childhood with congenital anomalies and progressive anemia. Diagnosis via chromosomal breakage tests; treatment includes bone marrow transplant Wikipedia.

  11. Post‑Hemorrhagic Anemia
    Acute blood loss from trauma or surgery leads to sudden drop in Hb and hypovolemia. Presents with shock signs. Treated by stopping bleeding and transfusing blood products Wikipedia.

  12. Vitamin B₁₂ Deficiency Anemia
    When the body lacks B₁₂—due to poor diet, malabsorption, or pernicious anemia—it cannot properly form DNA in RBC precursors. This leads to large, fragile RBCs (macrocytes) and low Hb. Presents with fatigue, numbness, and memory problems. Treated with injections or high‑dose oral B₁₂ Wikipedia.

  13. Folate Deficiency Anemia
    Similar to B₁₂ deficiency, folate shortage impairs DNA synthesis, producing macrocytic RBCs. It can result from poor diet, alcoholism, or certain drugs. Symptoms include tiredness, mouth sores, and neural tube defects in pregnancy. Folate supplements correct the deficiency nhs.uk.

  14. Aplastic Anemia
    A serious condition where bone marrow stops making enough blood cells of all types—red cells, white cells, and platelets. It can follow infections, toxins, or be idiopathic. Patients have severe fatigue, infections, and bleeding. Diagnosis is by bone marrow biopsy; treatment is immunosuppression or stem cell transplant Wikipedia.

  15. Hemolytic Anemia
    RBCs are destroyed faster than the marrow can replace them. Causes include autoimmune attacks, inherited defects (e.g., G6PD deficiency), or mechanical damage. Presents with jaundice, dark urine, and enlarged spleen. Managed by treating the trigger and sometimes removing the spleen Wikipedia.

  16. Sickle Cell Anemia
    An inherited hemoglobinopathy where red cells sickle under low oxygen, causing blockage in vessels and early cell breakdown. Symptoms start in childhood: pain episodes, anemia, and organ damage. Treatment includes hydration, pain control, and hydroxyurea; curative options include bone marrow transplant Wikipedia.

  17. Anemia of Chronic Disease
    Long‑term inflammation from infections, autoimmune diseases, or cancer raises hepcidin levels, trapping iron and reducing RBC production. Typically normocytic, patients have mild to moderate anemia. Managing the underlying disease is key Wikipedia.

  18. Chronic Kidney Disease (CKD)–Related Anemia
    Damaged kidneys produce less erythropoietin, leading to fewer RBCs. Present as normocytic anemia with fatigue and reduced exercise tolerance. Treated with erythropoiesis‑stimulating agents and iron supplementation Wikipedia.

  19. Myelodysplastic Syndrome (MDS)
    A bone marrow disorder where stem cells produce abnormal blood cells that die early. Presents with cytopenias, including anemia. Risk of progression to leukemia. Diagnosis via bone marrow exam; treatment ranges from supportive care to stem cell transplant Wikipedia.

  20. Hereditary Spherocytosis
    Defects in RBC membrane proteins cause spherocytes that are prematurely destroyed by the spleen, leading to chronic hemolytic anemia and splenomegaly Wikipedia.
  21. Hemodilutional anemia arises when plasma volume increases disproportionately (for instance in pregnancy or fluid overload), diluting red blood cells so that hemoglobin concentration falls despite normal cell size. Wikipedia

Some Key Description

1. Iron deficiency anemia 

  • often falls into this category. In this case, the disorder is brought on by a shortage of iron, most often caused by blood loss.
  • When blood is lost, the body reacts by pulling in water from tissues outside the bloodstream in an attempt to keep the blood vessels filled. This additional water dilutes the blood, and, as a result, the red blood cells are diluted.
  • Blood loss can be categorized as acute and rapid or chronic. Rapid blood loss can include surgery, childbirth, trauma, or a ruptured blood vessel.
  • Chronic blood loss is more frequent among patients diagnosed with anemia. Here, the blood loss can be a result of stomach ulcers, cancer, or tumor.
  • Gastrointestinal conditions – such as ulcers, hemorrhoids, cancer, or gastritis
  • Use of non-steroidal anti-inflammatory drugs (NSAIDs) – such as aspirin and ibuprofen
  • Menstrual bleeding

2. Anemia due to low red blood cell productions

  • Located in the center of our bones is a soft, spongy tissue, called bone marrow, it is essential for the creation of red blood cells. Bone marrow produces stem cells, which develop into red blood cells, white blood cells, and platelets.
  • Bone marrow can be affected by a number of diseases, including leukemia, where abnormal white blood cells are produced in excess, which disrupts normal production of red blood cells.
  • Other examples of anemias caused by decreased or faulty red blood cells are:

3. Sickle cell anemia

  • Red blood cells are misshapen and break down abnormally quickly. The crescent-shaped blood cells can also get stuck in smaller blood vessels, causing pain.
  • Iron-deficiency anemia – not enough red blood cells are produced because not enough iron is present in the body. This can be because of a poor diet, menstruation, frequent blood donation, endurance training, certain digestive conditions, such as Crohn’s disease, surgical removal of part of the gut, and some foods.
  • Bone marrow and stem cell problems – for instance, aplastic anemia occurs when there are little or no stem cells present. Thalassemia occurs when red blood cells can’t grow and mature properly.

4. Vitamin deficiency anemia

  • Vitamin B-12 and folate are both essential for the production of red blood cells; therefore, if either is deficient, red blood cell production will be too low. Examples of this type of anemia are megaloblastic anemia and pernicious anemia.

5. Anemia caused by the destruction of red blood cells

  • Red blood cells typically have a life span of 120 days in the bloodstream, but they can be destroyed or removed beforehand.
  • One type of anemia that falls into this category is autoimmune hemolytic anemia, where the body’s immune system mistakenly identifies its own red blood cells as a foreign substance and attacks them. Excessive hemolysis (red blood cell breakdown) can occur for many reasons, including:
  • Infections
  • Certain drugs – some antibiotics, for instance
  • Snake or spider venom
  • Toxins produced through advanced kidney or liver disease
  • Autoimmune attack – for instance hemolytic disease
  • Severe hypertension
  • Vascular grafts and prosthetic heart valves
  • Clotting disorders
  • Enlargement of the spleen
  • There are a LOT of diseases and conditions which can lead to anemia. These diseases can be grouped together into four broad causes of having too few red blood cells (RBCs) in blood.

6. Aplastic anemia

  • folic acid deficiency  iron deficiency anemia kidney disease leukemia and myelodysplastic syndrome thalassemia
  • pernicious anemia (vitamin B12 deficiency)
  • chronic diseases (e.g. HIV, Crohn’s disease, etc…)( Increased destruction of RBCs
  • glucose-6-phosphate dehydrogenase deficiency

7. Hemolytic anemia

  • sickle cell anemia
  • transfusion reactions , Loss of RBCs (bleeding) ,gastrointestinal ulcers
  • major injuries or surgery menstruation , Dilution of RBCs (fluid overload) ,pregnancy

Causes of Anemia

  1. Blood Loss
    Acute or chronic bleeding—from trauma, surgery, ulcers, or heavy menstruation—reduces total red blood cell volume, leading to anemia when production cannot keep up.

  2. Iron Deficiency
    Inadequate intake of iron-rich foods (meat, beans, leafy greens) or poor absorption in conditions like celiac disease deprives the body of the key element for hemoglobin synthesis.

  3. Vitamin B12 Deficiency
    A diet lacking animal products or impaired absorption in the stomach or small intestine causes insufficient B12, disrupting red cell maturation.

  4. Folate Deficiency
    Low folate intake—common in malnutrition, alcoholism, and certain drug therapies—hurts DNA synthesis in developing red blood cells.

  5. Chronic Kidney Disease
    Diseased kidneys produce less erythropoietin, a hormone that signals the bone marrow to make red blood cells, leading to anemia over time.

  6. Rheumatoid Arthritis
    Persistent inflammation increases hepcidin levels, trapping iron in storage sites and hindering its use for hemoglobin production (anemia of chronic disease).

  7. Autoimmune Disorders
    Conditions like lupus can attack red cells directly (autoimmune hemolytic anemia) or damage bone marrow, reducing blood cell production.

  8. Bone Marrow Disorders
    Aplastic anemia, myelodysplastic syndromes, leukemia, and other marrow diseases impair the production of healthy blood cells.

  9. Genetic Mutations
    Inherited defects—such as sickle cell disease, thalassemia, and hereditary spherocytosis—disrupt normal hemoglobin structure or red cell membrane integrity.

  10. Infections
    Certain infections (malaria, HIV, hepatitis) can directly destroy red blood cells or suppress marrow function.

  11. Medications and Toxins
    Chemotherapy drugs, some antibiotics, and toxins like benzene damage bone marrow or provoke hemolysis.

  12. Nutritional Deficiencies
    Severe malnutrition deprives the body of multiple vitamins and minerals needed for red cell production.

  13. Pregnancy
    Increased blood volume and iron demands during pregnancy can outpace supply, causing mild anemia in many women.

  14. Gastrointestinal Disorders
    Diseases like Crohn’s or ulcers lead to chronic bleeding or malabsorption of iron and vitamins.

  15. Lead Poisoning
    Lead interferes with several enzymes in heme synthesis, leading to anemia, abdominal pain, and neurological symptoms.

  16. Alcohol Abuse
    Alcohol damages bone marrow cells directly and can lead to poor nutrition, compounding anemia risk.

  17. Hypothyroidism
    Low thyroid hormone slows metabolism and can blunt marrow activity, leading to normocytic anemia.

  18. Hemolytic Transfusion Reactions
    Incompatible blood transfusions trigger rapid destruction of donor and recipient red cells, causing an acute anemia.

  19. Sheehan’s Syndrome
    Postpartum pituitary gland damage reduces erythropoietin-stimulating hormones, leading to anemia in severe cases.

  20. Parasitic Infections
    Hookworm and schistosomiasis consume blood or damage the intestinal lining, resulting in chronic blood loss and anemia.

  21. Folate Deficiency
    Folate (vitamin B₉) is essential for thymidine synthesis in DNA. Poor dietary intake, malabsorption (celiac disease), increased requirements (pregnancy), or medications (methotrexate) can deplete folate, resulting in megaloblastic macrocytosis WikipediaMedscape.

  22. Methotrexate Therapy
    Methotrexate inhibits dihydrofolate reductase, blocking folate recycling and DNA synthesis. Chronic low‐dose therapy for arthritis or high‐dose oncology regimens can precipitate megaloblastic changes Wikipedia.

  23. Trimethoprim/Sulfamethoxazole
    Trimethoprim interferes with folate metabolism, while sulfamethoxazole inhibits dihydropteroate synthase in bacteria but may also affect host folate pathways. Prolonged use can lead to macrocytosis Wikipedia.

  24. Anticonvulsant Medications (Phenytoin, Valproic Acid)
    These drugs can impair folate absorption or metabolism, leading to megaloblastic macrocytosis over months of therapy Wikipedia.

  25.  Zidovudine (AZT)
    An antiretroviral that inhibits DNA polymerase-γ in mitochondria, zidovudine can cause macrocytosis even before anemia develops, likely via direct marrow toxicity Wikipedia.

  26. Hydroxyurea
    Used in myeloproliferative disorders and sickle-cell disease, hydroxyurea’s effects on DNA synthesis can yield macrocytic changes in erythroid precursors Wikipedia.

Symptoms of Anemia

  1. Fatigue
    The most common symptom, caused by reduced oxygen delivery to muscles and organs, leading to a persistent feeling of tiredness.

  2. Weakness
    Muscle strength decreases when less oxygen reaches muscle tissue, making everyday tasks more difficult.

  3. Paleness (Pallor)
    Reduced hemoglobin makes skin, gums, and nail beds appear unusually pale, especially in fair-skinned individuals.

  4. Shortness of Breath
    Lower oxygen-carrying capacity forces the body to increase breathing rate, causing breathlessness even with mild activity.

  5. Dizziness or Lightheadedness
    Inadequate oxygen supply to the brain can cause faintness or a spinning sensation, particularly when standing quickly.

  6. Cold Hands and Feet
    Poor circulation and low red cell count can make extremities feel chilled, as the body prioritizes core organs.

  7. Chest Pain
    Severe anemia can strain the heart, causing chest discomfort or angina-like pain, especially in those with underlying heart disease.

  8. Headache
    Brain tissue deprived of oxygen may trigger headaches or migraines in some people with anemia.

  9. Difficulty Concentrating
    Cognitive function requires a constant oxygen supply; reduced levels can impair attention and memory.

  10. Rapid or Irregular Heartbeat
    The heart compensates for low oxygen by beating faster or more forcefully, which may be felt as palpitations.

  11. Leg Cramps
    Poor oxygenation of leg muscles during activity or at night can lead to painful cramps.

  12. Restless Legs Syndrome
    Some people with anemia experience an uncontrollable urge to move their legs, especially at night.

  13. Brittle Nails
    Chronic anemia can affect keratin production, leading to nails that crack or split easily.

  14. Jaundice
    In hemolytic anemias, rapid red cell breakdown raises bilirubin levels, causing yellowing of the skin and eyes.

  15. Sore or Smooth Tongue
    Deficiencies of iron, B12, or folate can lead to glossitis—an inflamed, sore, or unusually smooth tongue.

Further Diagnostic Tests

Physical Exam Tests

  1. Skin and Mucosal Inspection
    The clinician checks for pallor in the face, palms, and under the eyelids; dark-skinned individuals may show pallor in conjunctiva or nail beds.

  2. Palpation of the Spleen
    Enlargement of the spleen (splenomegaly) suggests hemolysis or certain bone marrow disorders contributing to anemia.

  3. Cardiac Auscultation
    Listening for murmurs or rapid heartbeats can indicate the heart’s compensatory response to low oxygen levels.

Manual Tests

  2. Peripheral Blood Smear
    A stained smear allows microscopy of red cell shape, size, and color—vital clues for diagnosing types like sickle cell, spherocytosis, or megaloblastic anemia.

  3. Serum Ferritin
    Reflects iron stores; low ferritin is a sensitive marker for iron deficiency anemia.

  4. Serum Iron
    Measures circulating iron bound to transferrin; low levels point to deficiency, while high levels can occur in hemolysis.

  5. Total Iron‑Binding Capacity (TIBC)
    Indicates the blood’s capacity to bind iron; elevated in iron deficiency and low in anemia of chronic disease.

  6. Vitamin B12 Level
    Low serum B12 confirms deficiency anemia; values below 200 pg/mL are diagnostic in the right clinical context.

  7. Folate (Vitamin B9) Level
    Low red blood cell or serum folate levels indicate folate deficiency, a cause of macrocytic anemia.

  8. Reticulocyte Count (Automated)
    Automated machines quantify young red cells to assess if the marrow is responding appropriately—high in hemolysis or bleeding, low in production defects.

  9. Lactate Dehydrogenase (LDH)
    Elevated LDH suggests increased red cell destruction, as this enzyme is released from broken cells.

  10. Bilirubin (Indirect)
    High levels of unconjugated bilirubin indicate hemolytic anemia, since rapid breakdown of red cells overwhelms liver processing.

  11. Haptoglobin
    A protein that binds free hemoglobin; low haptoglobin levels signal hemolysis when red cells are destroyed in circulation.

The formula to calculate iron requirement to replete iron stores in adults.

Formula
Elemental iron (mg) = 50 × [0.442 (desired Hgb g/L minus observed Hgb g/L) × lean body weight (see below for men and women) + 0.26 × lean body weight]
Lean body weight
For men: lean body weight = 50 kg + 2.3 kg for each inch in height over 60 inches
For women: lean body weight = 45.5 kg + 2.3 kg for each inch in height over 60 inches
Note: use actual body weight if lean body weight is less than actual weight.

  • Oral iron supplements are the best way to restore iron levels for people who are iron deficient, but they should be used only when dietary measures have failed. However, iron supplements cannot correct anemias that are not due to iron deficiency.
  • Iron replacement therapy can cause gastrointestinal problems, sometimes severe ones. Excess iron may also contribute to heart disease, diabetes, and certain cancers. Doctors generally advise against iron supplements in anyone with a healthy diet and no indications of iron deficiency anemia.
  • Treatment of Anemia of Chronic Disease. In general, the best treatment for anemia of chronic diseases is treating the disease itself. In some cases, iron deficiency accompanies the condition and requires iron replacement. Erythropoietin, most often administered with intravenous iron, is used for some patients.

Oral Iron Supplement

  • Supplement Forms. There are two forms of supplemental iron: ferrous and ferric. Ferrous iron is better absorbed and is the preferred form of iron tablets. Ferrous iron is available in three forms: ferrous fumarate, ferrous sulfate, and ferrous gluconate.
  • The label of an iron supplement contains information both on the tablet size (which is typically 325 mg) and the amount of elemental iron contained in the tablet (the amount of iron that is available for absorption by the body.) When selecting an iron supplement, it is important to look at the amount of elemental iron.

A 325 mg iron supplement contains the following amounts of elemental iron depending on the type of iron:

  • Ferrous fumarate. 108 mg of elemental iron
  • Ferrous sulfate. 65 mg of elemental iron
  • Ferrous gluconate. 35 mg of elemental iron

Dosage. Depending on the severity of your anemia, as well as your age and weight, your doctor will recommend a dosage of 60 – 200 mg of elemental iron per day. This means taking one iron pill 2 – 3 time during the day. Make sure your doctor explains to you how many pills you should take in a day and when you should take them. Never take a double dose of iron.

Intravenous or Injected Iron

In some cases, iron is administered through muscular injections or intravenously. Intravenous iron has the advantage of causing less gastrointestinal discomfort and inconvenience. It may be in the form of iron dextran (Dexferrum, InFed), sodium ferric gluconate complex in sucrose (Ferrlecit), or iron sucrose (Venofer). Ferrlecit or Venofer are proving to be at least equally effective and safer than iron dextran.

Candidates. The injected or intravenous forms should be limited to the following patients with iron deficiency:

  • People with iron deficiency anemia in whom oral therapy has clearly failed.
  • Patients with bleeding disorders in which blood loss continues to exceed the rate at which oral iron is absorbed.
  • In emergencies, when people need red blood cells but transfusion is not appropriate or available.
  • In people with serious gastrointestinal disorders, such as inflammatory bowel disease, who cannot take iron therapy by mouth.
  • People undergoing hemodialysis who receive supplemental erythropoietin therapy. Sodium ferric gluconate complex in sucrose (Ferrlecit) or iron sucrose (Venofer) is specifically approved as first-line therapy for these patients.

Certain patients, even if they meet these qualifications, may not be appropriate candidates or should be monitored closely for complications. They include:

  • Patients with any underlying autoimmune disease.
  • Malnourished patients who also have an underlying infection.
  • Patients who are at risk for iron overload.

Side Effects. Some side effects differ depending on how the iron is administered and include the following:

  • Muscular injections include pain at the site.
  • Intravenous administration can cause pain in the vein, flushing, and metallic taste, all of which are brief.

For both methods, side effects and serious complications can include:

  • Blood clots
  • Fever
  • Joint aches
  • Headache
  • Rashes
  • A delayed reaction of joint and muscle aches, headache, and malaise occurs 1 – 2 days after the infusion (most commonly with iron dextran) in about 10% of patients. These symptoms respond quickly to NSAIDs, such as ibuprofen or naproxen, in most people.
  • Iron toxicity. Symptoms include nausea, dizziness, and a sudden drop in blood pressure. Sodium ferric gluconate in sucrose (Ferrlecit) or iron sucrose (Venofer) may pose a lower risk for toxicity than iron dextran.
  • Allergic reactions. Allergic reactions that occur with intravenous iron can be very serious and, in rare cases, even fatal. Iron dextran appears to pose a much higher risk than sodium ferric gluconate complex in sucrose or iron sucrose, although allergic reactions can also occur with the latter forms.

Oral and injected iron should never be given at the same time. Intravenous iron therapy may be appropriate for some pregnant women who meet these requirements, depending on the pregnancy term and other factors.

Blood Transfusions

  • Transfusions are used to replace blood loss due to injuries and during certain surgeries. They are also commonly used to treat severely anemic patients who have thalassemia, sickle cell disease, myelodysplastic syndromes, or other types of anemia. Some patients require frequent blood transfusions. Iron overload can be a side effect of these frequent blood transfusions. If left untreated, iron overload can lead to liver and heart damage.
  • Iron chelation therapy is used to remove the excess iron caused by blood transfusions. Patients take a drug that binds to the iron in the blood. The excess iron is then removed from the body by the kidneys. For many years, deferoxamine (Desferal) was the only drug used in chelation therapy. This drug is usually injected intravenously, using an infusion pump. The infusion can last 8 – 12 hours and may be needed 5 – 7 days a week until iron levels are normal.
  • A new drug, deferasirox (Exjade), was approved in 2005 for children and adults as a once-daily treatment for iron overload due to blood transfusions. It does not require injections. Patients mix the deferasirox tablets in liquid and drink the medicine. However, deferoxamine can cause gastrointestinal tract ulcerations and hemorrhage and patients should be carefully monitored. Deferoxamine can interact with certain types of medications such as nonsteroidal anti-inflammatory drugs, corticosteroids, bisphosphonates, and anticoagulants.

Erythropoiesis Stimulating Drugs

  • Erythropoietin is the hormone that acts in the bone marrow to increase the production of red blood cells. It has been genetically engineered as recombinant human erythropoietin (rHuEPO) and is available as epoetin alfa (Epogen, Procrit, and Eprex). Novel erythropoiesis stimulating protein (NESP), also called darbepoetin alfa (Aranesp), lasts longer in the blood than epoetin alfa and requires fewer injections. These medications are also called “erythropoiesis-stimulating drugs.”
  • Levels of erythropoietin are reduced in anemia of chronic disease. Injections of synthetic erythropoietin can help increase the number of red blood cells in order to avoid receiving blood transfusions. Erythropoietin is used to treat anemia. It does not help improve anemia symptoms, fatigue, or quality of life for patients with cancer or HIV. This drug can cause serious side effects, including blood clots, and is approved only for treating patients with anemia related to the following conditions:
  • Cancer. For select patients, erythropoietin is used to treat the anemia associated with chemotherapy.
  • Chronic kidney failure. Erythropoietin is an important anemia treatment for patients with chronic kidney failure, including those on dialysis.
  • HIV/AIDS. Erythropoietin helps treat the anemia caused by zidovudine (AZT) therapy.
  • Erythropoiesis-Stimulating Drugs and Cancer. Erythropoietin should be used only to treat anemia caused by chemotherapy — not anemia due to other causes in patients with cancer. Erythropoietin treatment does not help prolong survival. In fact, these drugs can shorten survival time and cause tumors to grow faster. Discuss with your doctor whether an erythropoiesis-stimulating drug is appropriate for you.
  • Survival and tumor growth risks are especially pronounced for patients with advanced breast, head and neck, lymphoid, or non-small cell lung cancer when dosing attempts to achieve a hemoglobin level of 12 g/dL or greater. However, there may be similar risks for patients dosed to less than 12 g/dL. (The American Society of Clinical Oncology and the American Society of Hematology recommend starting erythropoietin when a patient’s hemoglobin level falls to less than 10 g/dL.) The doctor should use the lowest effective dose and erythropoietin treatment should be stopped as soon as the chemotherapy course is completed.
  • Erythropoiesis-Stimulating Drugs and Chronic Kidney Failure. For patients with chronic kidney failure, the FDA recommends that erythropoiesis-stimulating drugs be used to maintain hemoglobin levels between 10 – 12 g/dL. (The exact level within this range varies by individual.) There is a greater risk of death and serious cardiovascular events, such as heart attack, stroke, and heart failure when these drugs are used to achieve higher hemoglobin levels (13.5 – 14g/dL) compared to lower hemoglobin levels (10- 11.3 g/dL).

In 2007, the Food and Drug Administration (FDA) made major changes to the prescribing information for erythropoiesis-stimulating drugs. The new labels describe in detail the risks that Aranesp, Epogen, and Procrit can pose to patients with cancer and chronic kidney disease. The FDA has also established separate dosing recommendations for each of these conditions.

Home Remedies for Anemia

Red blood cells contain hemoglobin, an iron-based protein that helps blood cells carry oxygen. When you are anemic, your blood can’t deliver the proper oxygen supply to your organs and tissues.

According to the World Health Organization, males who have less than 13 grams of hemoglobin per deciliter are anemic. For women, the criteria is less than 12 grams of hemoglobin per deciliter.

  • Anything that disrupts the normal life span of the red blood cells may cause anemia, including a decrease in red blood cell production, an increase in destruction of red blood cells or excessive blood loss. There are different types of anemia, depending on their cause.
  • Women and people with chronic diseases are at highest risk for anemia. Some of the conditions that may cause it are heavy blood loss during menstruation, pregnancy, ulcers, intestinal disorders, cancer, bleeding disorders, other chronic diseases, or a deficiency of iron, folic acid, vitamin B12. Certain types of anemia can also be inherited.
  • Symptoms vary depending on the cause and may range from mild to severe. Common symptoms are fatigue, pale skin, a fast or irregular heartbeat, shortness of breath, chest pain, dizziness, cognitive problems, headaches, cold hands and feet, lack of energy, hair loss and high or low blood pressure.
  • You can easily treat and prevent some types of anemia at home with some simple home remedies. Follow any of these remedies until your hemoglobin level becomes normal.

Beetroot

Beetroot is highly beneficial for those who suffer from anemia due to iron deficiency, which is the most common of all types of anemia. It has high iron content, along with fiber, calcium, potassium, sulfur and vitamins.

In addition to providing nutrition, beetroot helps cleanse the body and supply more oxygen throughout the body. This in turn helps increase the body’s red blood cell count.

  • Blend one medium-size beetroot, three carrots and one-half of a sweet potato in a juicer. Drink this juice once daily.
  • You can also eat beetroots as a cooked vegetable or in a salad. Eat the peel along with the beetroot for maximum nutritional value.

 Blackstrap Molasses

Blackstrap molasses is considered a nutritional powerhouse, especially for those who are anemic.

It is a good source of iron, B vitamins and other essential minerals that help increase red blood cell production. A tablespoon of blackstrap molasses supplies almost 15 percent of your daily iron needs.

  • Mix one tablespoon of blackstrap molasses in a cup of hot water or milk. Drink this once or twice daily. This drink is highly beneficial for pregnant women.
  • Another option is to combine two teaspoons each of blackstrap molasses and apple cider vinegar in one cup of water. Drink this once daily.

Spinach

A diet rich in green leafy vegetables like spinach is one of the best home cures for anemia. Spinach is rich in iron as well as vitamin B12 and folic acid, energy-boosting nutrients that the body needs to recover from anemia.

A one-half cup of spinach provides almost 35 percent of your daily value of iron and 33 percent of your daily value of folic acid.

  • Drink spinach soup twice daily. To prepare the soup, take 1 cup of blanched spinach and puree it by adding a little water. Heat 1 teaspoon of extra-virgin olive oil in a pan, sauté some chopped garlic cloves and onion in it until brown. Add the pureed spinach and a little salt and cook on low heat for 5 – 10 minutes.
  • Mix two teaspoons of honey in a glass of fresh spinach juice. Drink this once daily.

Follow either of these remedies for at least one month.

Pomegranate

Pomegranate is rich in iron and other minerals, such as calcium and magnesium. It also contains vitamin C, which helps improve the body’s absorption of iron. This results in more red blood cells and an increase in the hemoglobin level.

  • Mix one cup of pomegranate juice, one-fourth teaspoon of cinnamon powder and two teaspoons of honey. Drink this daily with your breakfast.
  • Alternatively, take two teaspoons of dried pomegranate seed powder with a glass of warm milk one or two times daily.
  • You can also eat a medium-size pomegranate every morning on an empty stomach.

Sesame Seeds

Sesame seeds are also great for treating anemia due to their high iron content. One-fourth cup of sesame seeds provides almost 30 percent of the daily iron requirement.

  • Soak two tablespoons of black sesame seeds in water for two to three hours. Strain and make a paste of the soaked seeds. Add one tablespoon of honey and mix well. Have this mixture twice daily.
  • Soak one teaspoon of black sesame seeds in warm water for two hours. Grind the mixture into a paste and then strain it to get the emulsion. Mix the emulsion in a cup of warm milk, add honey or jaggery and drink it once daily.

 Dates

Dates are a rich source of iron as well as vitamin C that plays an important role in the body’s absorption of iron.

  • Soak two dates in a cup of milk overnight. The next morning, eat the dates and drink the milk on an empty stomach.
  • Alternatively, you can eat some dry dates on an empty stomach in the morning, followed by a cup of warm milk.

 Apple

Being rich in nutrients including iron, apples help a lot in treating anemia.

  • Eat at least one apple daily. If possible, opt for green apples and eat them with their skin.
  • You can also mix equal parts of fresh apple juice and beetroot juice and a little honey. Drink this juice twice daily.

Banana

High in iron, banana stimulates the production of hemoglobin and many other enzymes that are essential for the formation of red blood cells. Also, it is a good source of magnesium that aids in hemoglobin synthesis.

  • Eat one ripe banana along with one tablespoon of honey twice daily.
  • Alternatively, mix one mashed ripe banana and one tablespoon of Indian gooseberry (amla) juice. Eat this two or three times daily.

 Dried Black Currant

Due to its high concentrations of iron and vitamin C, dried black currant has been found to be a very effective treatment for anemia. Vitamin C enhances the body’s ability to absorb the iron, increasing red blood cells and hemoglobin.

  1. Soak 10 to 12 dried black currants in water overnight.
  2. The next morning, remove them from the water and remove the seeds.
  3. Eat them daily before eating your breakfast.
  4. Follow this remedy for a few weeks.

Fenugreek

The high iron content in fenugreek will help maintain the iron in your blood. It also aids new red blood cell production. Both the leaves and seeds of fenugreek can be used in the treatment of anemia.

  • Cook one cup of rice with two teaspoons of fenugreek seeds. Add some salt and eat it once daily for at least two to three weeks.
  • You can also use fenugreek leaves in your cooking, especially in soups or salads.

These home remedies are great for restoring a healthy red blood cell count in people who have anemia. Following a well-balanced diet is essential to prevent a recurrence.
