Acquired Generalized Hypertrichosis

Acquired Generalized Hypertrichosis is a medical condition characterized by excessive hair growth over the entire body, including areas where hair is not typically found in individuals of the same age, gender, and race. This condition can occur at any age, but it is more commonly seen in adults. Unlike congenital generalized hypertrichosis, which is present at birth, acquired generalized hypertrichosis is a result of a specific underlying cause and is not hereditary.

The excessive hair growth can occur as a result of several factors, including hormonal imbalances, certain medications, and certain medical conditions. Hormonal imbalances, such as hyperandrogenism, can result in an increase in the production of androgens, which are male hormones. This increase in androgens can lead to excessive hair growth on the face, chest, and back.

Causes

The condition is not hereditary and is acquired through various causes. In this article, we will discuss the main causes of acquired generalized hypertrichosis.

  1. Drugs and Medications

One of the most common causes of acquired generalized hypertrichosis is the use of drugs and medications. A number of drugs have been associated with causing hypertrichosis as a side effect. Some of the drugs that have been linked to hypertrichosis include minoxidil, cyclosporine, oral contraceptives, and anabolic steroids. Minoxidil is a medication that is used to treat hair loss, but it has been found to cause excessive hair growth on areas of the body where hair is not normally present. Cyclosporine is an immunosuppressant that is used to prevent transplant rejection, but it has also been linked to hypertrichosis. Oral contraceptives are hormone-based medications that are used to prevent pregnancy, but they have also been found to cause hypertrichosis in some women. Anabolic steroids are synthetic versions of the male hormone testosterone, and they have been linked to hypertrichosis in both men and women.

  1. Hormonal Imbalances

Hormonal imbalances can also cause acquired generalized hypertrichosis. Hormonal imbalances can occur due to a variety of reasons, including pregnancy, menopause, and hormonal disorders such as polycystic ovary syndrome (PCOS). Pregnancy and menopause are both associated with changes in hormone levels, which can cause excessive hair growth. PCOS is a hormonal disorder that affects women and is characterized by an increase in male hormones, which can cause excessive hair growth.

  1. Diseases and Medical Conditions

A number of diseases and medical conditions have been linked to acquired generalized hypertrichosis. Some of the medical conditions that have been linked to hypertrichosis include acromegaly, hirsutism, and congenital adrenal hyperplasia. Acromegaly is a condition in which the body produces too much growth hormone, which can cause excessive hair growth. Hirsutism is a condition in which women experience excessive hair growth on the face and body, which is caused by an increase in male hormones. Congenital adrenal hyperplasia is a genetic condition in which the adrenal glands produce too much androgen, which can cause excessive hair growth.

  1. Nutritional Deficiencies

Nutritional deficiencies can also cause acquired generalized hypertrichosis. Some of the nutritional deficiencies that have been linked to hypertrichosis include iron-deficiency anemia, vitamin D deficiency, and protein-energy malnutrition. Iron-deficiency anemia is a condition in which the body does not have enough iron, which is necessary for the production of hemoglobin. Vitamin D deficiency can cause a number of health problems, including hypertrichosis. Protein-energy malnutrition is a condition in which the body does not get enough protein and energy, which can cause a number of health problems, including hypertrichosis.

  1. Psychological Stress

Psychological stress can also cause acquired generalized hypertrichosis. Stress can cause changes in hormone levels, which can cause excessive hair growth. Stress can also cause changes in the immune system, which can cause a number of health problems, including hypertrichosis.

Symptoms

This condition can occur at any age and is not limited to a particular gender or race. It can be caused by various underlying medical conditions or medications and may affect different parts of the body such as the face, arms, legs, and trunk.

The main symptoms of acquired generalized hypertrichosis include:

  1. Excessive hair growth: The most obvious symptom of this condition is excessive hair growth on areas that are typically hairless or minimally haired. The hair may be thick, coarse, and dark in color, and may grow in a pattern that is unusual for that area of the body.
  2. Changes in hair texture: In some cases, the hair may become curly or wavy, or may develop a different texture than the normal hair on the body.
  3. Rapid hair growth: The hair growth may occur rapidly, making it difficult to keep up with the amount of hair that needs to be trimmed or shaved.
  4. Unusual hair growth patterns: The hair may grow in patterns that are unusual for the affected area of the body. For example, hair may grow on the face in a beard-like pattern or on the legs in a pattern that resembles that of a man’s legs.
  5. Pain or discomfort: In some cases, the hair growth may cause itching, pain, or discomfort, especially if the hair is long and rubs against clothing or skin.
  6. Psychological distress: The excessive hair growth can be distressing for some people, causing them to feel self-conscious and embarrassed about their appearance.
  7. Impact on daily life: The excessive hair growth may affect a person’s daily life, making it difficult for them to engage in activities that they used to enjoy, such as swimming or wearing certain types of clothing.

In some cases, acquired generalized hypertrichosis may be accompanied by other symptoms, depending on the underlying cause of the condition. For example, if the condition is caused by an underlying medical condition, such as an endocrine disorder, other symptoms may include fatigue, weight changes, or changes in mood or behavior.

Diagnosis

The diagnosis of acquired generalized hypertrichosis typically involves a comprehensive evaluation by a physician, including a thorough medical history, physical examination, and laboratory tests.

The first step in diagnosing acquired generalized hypertrichosis is to take a thorough medical history. This will include questions about the onset and progression of the hair growth, any associated symptoms or conditions, and any medications or treatments that have been tried. The physician will also ask about any family history of hair loss or excessive hair growth, as well as any other medical conditions that may be contributing to the hair growth.

The next step in the diagnostic process is a physical examination. The physician will examine the affected areas for signs of hair growth, including thickness, color, and distribution. They will also check for any skin changes, such as redness, scaling, or inflammation, which may indicate an underlying medical condition.

Once the physical examination is complete, the physician may order a series of laboratory tests to help confirm the diagnosis of acquired generalized hypertrichosis and identify any underlying causes. These tests may include:

  1. Hormonal tests: Hormonal imbalances, such as those that occur with polycystic ovary syndrome (PCOS) or an overactive thyroid, can cause acquired generalized hypertrichosis. Hormonal tests, such as a testosterone level or thyroid function tests, can help identify any underlying hormonal imbalances that may be contributing to the hair growth.
  2. Blood tests: Blood tests can help identify any underlying medical conditions that may be contributing to the hair growth, such as anemia or diabetes.
  3. Skin biopsy: In some cases, a skin biopsy may be performed to help diagnose any underlying skin conditions that may be contributing to the hair growth, such as hirsutism or seborrheic dermatitis.
  4. Genetic testing: In some cases, acquired generalized hypertrichosis may be hereditary, and genetic testing may be performed to confirm a genetic cause.

Once the diagnosis of acquired generalized hypertrichosis has been confirmed, the physician will work with the patient to determine the best course of treatment. Treatment options may include medications, such as hormonal therapies or antibiotics, to address any underlying causes, as well as hair removal techniques, such as laser therapy or waxing.

Treatment

There are several treatments available for AGH, including medical and cosmetic options. The best treatment option will depend on the cause of the excessive hair growth and the severity of the condition.

Medical treatments for AGH include:

  1. Hormonal therapy: Hormonal imbalances, such as an overproduction of androgens (male hormones), can cause AGH. Hormonal therapy can help regulate hormone levels and reduce excessive hair growth. This may involve taking medications such as oral contraceptives, anti-androgens, or gonadotropin-releasing hormone (GnRH) agonists.
  2. Vitamin D supplementation: Vitamin D deficiency has been linked to AGH in some cases. Supplementing with vitamin D can help regulate hormone levels and reduce hair growth.
  3. Chemotherapy: Certain chemotherapy medications can cause AGH as a side effect. If this is the case, the hair growth will typically return to normal once the chemotherapy is discontinued.
  4. Discontinuing medication: If AGH is caused by a medication, discontinuing the medication can resolve the condition.

Cosmetic treatments for AGH include:

  1. Hair removal: Hair removal methods such as waxing, shaving, plucking, and electrolysis can be used to manage AGH. However, these methods are not permanent and will need to be repeated regularly.
  2. Laser hair removal: Laser hair removal uses light energy to destroy hair follicles and reduce hair growth. This is a more permanent solution than other hair removal methods, but multiple treatments may be needed to achieve the desired result.
  3. Microdermabrasion: Microdermabrasion is a cosmetic treatment that uses fine crystals to exfoliate the skin and remove hair. This method can be used on the face and other parts of the body affected by AGH.
  4. Topical creams: Topical creams containing retinoids and other hair growth inhibitors can be used to reduce hair growth in specific areas. However, these creams may not be effective for everyone and may cause skin irritation.

In conclusion, there are several treatment options available for AGH, including medical and cosmetic treatments. The best treatment option will depend on the cause of the excessive hair growth and the severity of the condition. It is important to consult a doctor or dermatologist to determine the most appropriate treatment plan.
