Bantu siderosis is an iron overload disease seen mostly in parts of sub-Saharan Africa. The body slowly takes in too much iron over many years. Most of the extra iron comes from regularly drinking traditional home-brewed beer made or stored in iron containers. The iron dissolves into the drink and gets absorbed by the gut. Some people also have a gene change that makes their body hold on to more iron than usual. The iron then deposits in organs—first in liver immune cells (Kupffer cells) and later in the liver itself, heart, pancreas, and other tissues. Over time this can cause liver scarring (cirrhosis), diabetes, heart problems, and skin darkening if not recognized early. This condition used to be called Bantu hemosiderosis or African nutritional hemochromatosis. Cambridge University Press & AssessmentWikipediaNCBIScienceDirect
Bantu siderosis is a kind of iron overload that was historically seen in parts of sub-Saharan Africa. It happens when a person takes in too much iron from food and drink for many years, most famously from home-brewed beer or fermented sorghum/maize made in iron pots or steel drums, which leach iron into the drink. Over time, the extra iron gets absorbed in the gut and is stored in body organs. Iron cannot be actively excreted by the body, so it builds up slowly in the liver, heart, pancreas, and endocrine glands. This extra iron can scar the liver (fibrosis → cirrhosis), weaken the heart (cardiomyopathy, arrhythmias), raise blood sugar (diabetes), and cause fatigue and joint pain. Unlike hereditary hemochromatosis, Bantu siderosis is environmental/dietary, not driven by HFE gene mutations. The mainstays of care are: removing iron (phlebotomy/venesection or chelation drugs), stopping excess iron intake, treating organ complications, limiting alcohol, and vaccinating against hepatitis.
Other names
Bantu siderosis is also known by several names in medical writing. Common terms include African iron overload, Bantu hemosiderosis, and African nutritional hemochromatosis. These names reflect the same core idea: too much iron builds up in people from African communities, often linked to traditional brewing practices and sometimes to a genetic tendency to retain iron. Older literature may use “Bantu siderosis/hemosiderosis” because early reports came from Bantu-speaking populations; modern articles prefer “African iron overload” to avoid implying it affects only one language group. Some sources also discuss a dietary form (beer-related) and a genetic form (ferroportin-related), which can occur together. WikipediaNCBI
Types
1) Dietary (beer-related) African iron overload.
This type comes from long-term drinking of home-brewed beer with very high iron content because it was made or stored in iron pots or ungalvanized steel drums. Measurements show the iron content can be tens of milligrams per liter—much higher than commercial beer. With the move to commercial beer in cities, this form became less common in urban areas but can persist in rural places. WikipediaCambridge University Press & Assessment
2) Genetic-predisposition (ferroportin-related) iron overload.
Some people of African ancestry carry changes (polymorphisms) in the SLC40A1 gene (ferroportin). These variants can raise ferritin even when transferrin saturation is not high and lead to iron stored first in macrophages (like Kupffer cells). The best-studied variant is Q248H, which has been linked with higher ferritin in African-Americans. Gene–diet interaction likely explains why only some heavy beer drinkers develop the disease. PMCPubMedScienceDirect
3) Mixed form.
In many people, both factors—high iron intake from traditional beer and a ferroportin variant—work together to cause clinically important iron loading. Wikipedia
Causes and risk contributors
Note: The strongest evidence points to iron-rich home-brewed beer and, in some people, a ferroportin variant. Other items below describe patterns and contributors that increase exposure or promote iron loading over time.
Home-brewed beer made/stored in iron containers. Acidic fermentation pulls iron from ungalvanized drums or pots into the drink; repeated intake drives iron overload. WikipediaCambridge University Press & Assessment
Very high iron concentration in the beer. Studies report ~46–82 mg/L in traditional beer—far higher than commercial beer—so even a few liters per week add up. Wikipedia
Long duration of drinking. Years of exposure let iron slowly accumulate because the body has no natural way to excrete large amounts of iron. (General iron physiology.) NCBI
High volume consumed. Greater daily or weekly intake means more iron absorbed and stored over time. (General dose–response logic aligned with above.) Wikipedia
Genetic predisposition (ferroportin/SLC40A1 variants such as Q248H). This raises ferritin and favors iron storage in macrophages even when transferrin saturation is not markedly high. PMCPubMed
Gene–diet interaction. Not all people who drink traditional beer get iron overload; genetic factors explain part of that difference. Wikipedia
Rural residence with continued traditional brewing. Urban switch to commercial beer reduces exposure; rural use maintains risk. Wikipedia
Starting consumption at a young age. Earlier start gives more years for iron to build up before symptoms appear. (Physiology of cumulative load.) NCBI
Male sex or post-menopausal status. Lower regular iron loss (no menstruation) can lead to higher net iron storage across years. (General iron balance concepts.) NCBI
Coexisting liver disease (e.g., alcohol-related or viral hepatitis). These can raise ferritin and may worsen iron handling or organ injury once iron accumulates. Merck Manuals
Low access to commercial beer or non-iron brewing equipment. Practical barriers to safer alternatives keep exposure high. (Public health context derived from urban vs rural shift.) Wikipedia
Cultural practices that favor daily brewing/consumption. Regular social use maintains steady iron intake. (Contextual contributor aligned with above.) Cambridge University Press & Assessment
High carbohydrate fermentation producing acidity. Acidic brew enhances iron leaching from containers. (Mechanistic explanation consistent with observations.) Wikipedia
Nutrition patterns that enhance non-heme iron absorption. With certain meals or drinks, absorbed iron can increase; across years this magnifies load. (General iron absorption principles.) NCBI
Limited health screening. Without early checks (ferritin, MRI), loading continues unnoticed until organ damage develops. (General diagnostic delay effect.) jlpm.amegroups.org
Misclassification as typical hereditary hemochromatosis. If testing looks only for HFE mutations, the African pattern (often macrophage-first) can be missed. MedlinePlusScienceDirect
Repeated pregnancies without iron deficiency treatment (rare context). After menopause, lost protective iron loss stops; lifetime exposure still matters. (Iron balance logic; see physiology refs.) NCBI
Coexisting metabolic stress (e.g., fatty liver). Metabolic liver disease can coexist and compound liver injury from iron. (General iron-liver literature.) Merck Manuals
Household brewing in iron vessels beyond beer (less common). Any regularly consumed iron-leached beverage could contribute. (Mechanistic inference consistent with beer data.) Wikipedia
Family history of high ferritin without HFE mutations. Suggests a heritable non-HFE tendency (e.g., ferroportin variant) in some families. PubMed
Symptoms
Tiredness and weakness. Extra iron stresses organs and causes general fatigue that does not improve with rest. (Common in iron overload.) Mayo Clinic
Right upper belly discomfort or fullness. The liver gets enlarged (hepatomegaly), causing a dull ache under the right ribs. National Organization for Rare Disorders
Dark or “bronze” skin. Iron and melanin changes make the skin look darker over time. Mayo Clinic
Joint aches (arthralgia). Iron can irritate joints, leading to hand, knee, or ankle pain. Mayo Clinic
Swollen liver (hepatomegaly). Often one of the earliest clinical signs on exam. National Organization for Rare Disorders
Signs of cirrhosis later on. Fluid in the belly, easy bruising, or spider veins can appear with advanced liver scarring. Mayo Clinic
High blood sugar or diabetes symptoms. Iron damages the pancreas, causing thirst, frequent urination, and weight loss. Mayo Clinic
Heart rhythm problems (palpitations). Iron in the heart can trigger irregular beats. Mayo Clinic
Heart failure symptoms. Shortness of breath, ankle swelling, and fatigue can occur when the heart pumps poorly. Mayo Clinic
Decreased libido or impotence. Iron may affect hormone glands, lowering sex hormones. Mayo Clinic
Abdominal swelling (ascites) or leg edema. Signs of advanced liver or heart involvement. Mayo Clinic
Easy tiredness with activity. Reduced heart function and anemia in some variants can lower exercise tolerance. (Pattern described in ferroportin disease.) PubMed
Loss of appetite and early satiety. Enlarged liver and systemic illness can reduce appetite. (General in chronic liver disease.) Mayo Clinic
Numbness/tingling (less common). Diabetes-related nerve problems may appear after pancreatic injury. (Secondary to diabetes.) Mayo Clinic
No symptoms at first. Many people feel well for years; only tests show high ferritin or iron in the liver. National Organization for Rare Disorders
Diagnostic tests
A) Physical examination
General inspection and skin color. The clinician looks for skin darkening (“bronze” tone) and overall health status; changes suggest long-standing iron loading. Mayo Clinic
Abdominal palpation for liver size. The doctor gently feels under the right ribs; a firm, enlarged edge suggests iron-related liver enlargement. National Organization for Rare Disorders
Spleen check. Feeling for a spleen tip; enlargement may occur with chronic liver disease or portal hypertension. (General exam finding in iron-related liver disease.) Mayo Clinic
Signs of cirrhosis on exam. Spider angiomas, fluid in the belly, muscle wasting, or jaundice point to advanced disease. Mayo Clinic
Cardiac and edema assessment. Listening for abnormal heart sounds, checking ankles for swelling, and looking for breathlessness to screen for iron-related heart injury. Mayo Clinic
B) Manual / bedside tests
Liver span percussion. Tapping the chest/abdomen to estimate liver size helps track enlargement over time alongside imaging. (Standard bedside technique.) Mayo Clinic
Bedside glucose measurement. Finger-stick glucose screens for diabetes caused by pancreatic iron deposition. Mayo Clinic
Functional capacity walk test. A simple timed walk notes breathlessness or fatigue that might reflect heart or liver disease burden. (Supportive clinical measure.) Mayo Clinic
C) Laboratory and pathological tests
Serum ferritin. Usually elevated in African iron overload; it estimates body iron stores but can also rise with inflammation, so results are interpreted with other tests. National Organization for Rare Disordersjlpm.amegroups.org
Transferrin saturation (TSAT), serum iron, and TIBC. In African iron overload and ferroportin disease, ferritin may be high with normal or only mildly high TSAT, unlike classic HFE hemochromatosis where TSAT is typically high. MedlinePlusScienceDirect
Liver function tests (ALT, AST, ALP, bilirubin, albumin, INR). These show current liver injury and reserve, guiding the urgency of care. jlpm.amegroups.org
Fasting glucose and HbA1c. Detects diabetes from pancreatic iron-related damage. Mayo Clinic
HFE genetic testing. Helps rule out common hereditary hemochromatosis (HFE-related) and supports an African iron overload pattern when negative. PMC
Ferroportin (SLC40A1) testing where available. Identifies non-HFE, macrophage-predominant iron overload patterns linked to SLC40A1 variants. PubMed
Hepcidin (research/limited availability). Abnormal hepcidin patterns can inform iron metabolism status but are not yet routine everywhere. jlpm.amegroups.org
Liver biopsy with iron staining (Perls’ Prussian blue). Shows macrophage-predominant iron deposition (Kupffer cells) early on; this pattern helps distinguish African iron overload/ferroportin disease from classic HFE disease. ScienceDirect
D) Electrodiagnostic tests
Electrocardiogram (ECG). Looks for iron-related rhythm problems or conduction changes that may occur with cardiac iron loading. Mayo Clinic
Holter monitor (ambulatory ECG). Records heart rhythm over 24–48 hours to catch intermittent arrhythmias linked to iron deposition. (Cardiac evaluation standard.) Mayo Clinic
E) Imaging tests
Abdominal ultrasound. A simple first test to check liver size, texture, spleen size, and fluid in the belly; helps screen for cirrhosis or other causes. jlpm.amegroups.org
MRI liver iron quantification (R2/T2).** The key noninvasive test to measure liver iron concentration; helps confirm overload and track response over time. CGH Journal
Cardiac MRI T2.* Measures iron in the heart muscle to evaluate risk for heart failure or arrhythmias. (Standard for iron cardiomyopathy assessment.) CGH Journal
Transient elastography (FibroScan). Non-invasive tool to estimate liver stiffness and scarring due to iron-related liver disease. (Widely used fibrosis assessment.) jlpm.amegroups.org
Targeted CT or MRI abdomen (anatomical). When needed to assess complications, masses, or advanced cirrhosis changes beyond iron quantification. (Complementary imaging.) jlpm.amegroups.org

Regular iron tests if at risk: ferritin and transferrin saturation.
Diet awareness: avoid iron-fortified products if already iron-loaded.
Time vitamin C away from high-iron meals (vitamin C boosts iron absorption).
Tea/phenol beverages with meals to reduce iron uptake (as tolerated).
Family/community education on safe brewing and cookware.
Early treatment of infections and metabolic conditions (e.g., diabetes).
When to see doctors (red flags)
Persistent fatigue, abdominal swelling, or yellow eyes/skin.
Dark stools or vomiting blood.
Shortness of breath, chest pain, palpitations, fainting.
Swelling of legs, sudden weight gain from fluid.
Very high ferritin or transferrin saturation on screening.
New high blood sugar, thirst, frequent urination.
Any side effect from chelation (rash, ringing in ears, vision change, low white cells).
Before starting supplements or major diet changes.
What to eat and what to avoid
Eat: whole grains/bran, legumes, nuts, and seeds (phytates bind iron).
Eat: dairy or calcium with higher-iron meals to reduce absorption.
Eat: fruits/vegetables away from iron-rich meals if high in vitamin C.
Eat: tea/coffee with meals (if tolerated) to lower iron uptake.
Eat: lean proteins in moderate portions; favor fish/chicken over large red-meat servings.
Avoid: iron-fortified cereals/flours if you already have iron overload.
Avoid: cooking acidic foods in cast-iron cookware.
Avoid: alcohol to protect liver.
Avoid: vitamin C tablets with iron-rich meals (take at other times if prescribed).
Avoid: raw shellfish (iron overload raises risk of severe Vibrio infections).
FAQs
Is Bantu siderosis genetic?
Mostly dietary/environmental, unlike classic hereditary hemochromatosis.Can it be cured?
You can remove excess iron (phlebotomy/chelation) and prevent re-accumulation; organ damage may improve if treated early.How is it diagnosed?
History of exposure + high ferritin, high transferrin saturation, MRI liver/heart iron, and sometimes liver biopsy if needed.What is the safest first treatment?
If blood counts allow, phlebotomy is simple and effective; otherwise oral chelation is used.How often are iron levels checked?
Commonly every 1–3 months during active removal, then every 3–6 months on maintenance.Do I need a special diet?
Yes—reduce iron intake/absorption, limit alcohol, use tea/calcium/phytate strategies with meals.Is exercise safe?
Usually yes, with medical clearance, and start slowly—especially if there is heart disease.Can the heart recover?
Myocardial iron can decrease with chelation; function may improve if treated early.What about pregnancy?
Preconception counseling is helpful; avoid iron supplements unless your doctor prescribes them.Do supplements help?
Some (tea polyphenols, calcium, fiber) may reduce absorption modestly. Always check with your clinician.Is vitamin C bad?
Vitamin C increases iron absorption; avoid taking it with high-iron meals (unless a doctor directs otherwise).Can kids get it?
Risk exists where iron-leaching brewing/cookware is used. Prevention and community education are key.What happens if I ignore it?
