Medical Conditions that Cause Hair Loss
Hair loss is a common problem that affects millions of people around the world. Although it is often associated with aging, there are many medical conditions that can cause hair loss in both men and women. In this article, we will explore some of the most common medical conditions that cause hair loss.
1. Androgenetic Alopecia
Androgenetic alopecia, also known as male pattern baldness or female pattern baldness, is the most common cause of hair loss in both men and women. It is a genetic condition that causes hair follicles to shrink and produce thinner and shorter hair over time. In men, it usually starts with a receding hairline and balding on the crown of the head, while in women, it results in thinning hair on the top of the head.
2. Telogen Effluvium
Telogen effluvium is a temporary hair loss condition that occurs due to stress, illness, or hormonal changes. It causes hair follicles to enter the resting phase of the hair growth cycle prematurely, leading to shedding of hair. The good news is that it usually resolves on its own within a few months.
3. Alopecia Areata
Alopecia areata is an autoimmune condition that causes hair loss in patches. It occurs when the immune system attacks hair follicles, leading to hair loss. It can affect people of all ages and can cause complete baldness in severe cases. There is no cure for alopecia areata, but treatments can help in regrowing hair.
4. Thyroid Disorders
Thyroid disorders such as hypothyroidism and hyperthyroidism can cause hair loss. Hypothyroidism, a condition in which the thyroid gland doesn't produce enough thyroid hormones, can cause hair to become brittle, dry, and prone to breakage. Hyperthyroidism, a condition in which the thyroid gland produces too much thyroid hormone, can cause hair to become thin and fine.
5. Iron Deficiency Anemia
Iron deficiency anemia is a common condition that occurs due to a lack of iron in the body. Iron is essential for the production of hemoglobin, a protein in red blood cells that carries oxygen to the body's tissues. When there is a lack of iron, the body can't produce enough hemoglobin, leading to anemia. One of the symptoms of iron deficiency anemia is hair loss.
6. Polycystic Ovary Syndrome (PCOS)
Polycystic ovary syndrome, or PCOS, is a common hormonal disorder that affects women of reproductive age. It occurs when the ovaries produce too much androgen, a male hormone. This hormonal imbalance can cause hair loss on the scalp and other areas of the body, such as the face and chest.
7. Lupus
Lupus is an autoimmune disease that can affect various parts of the body, including the skin, joints, and organs. It can cause hair loss due to inflammation and scarring of hair follicles. Hair loss in lupus usually occurs in patches and can be temporary or permanent, depending on the severity of the condition.
8. Certain Medications
Certain medications, such as chemotherapy drugs, anticoagulants, and antidepressants, can cause hair loss as a side effect. Hair loss due to medication usually resolves once the treatment is completed or stopped.
In conclusion, hair loss can be caused by various medical conditions. If you are experiencing hair loss, it is important to see a healthcare provider to determine the underlying cause and appropriate treatment. In many cases, hair loss can be prevented or treated with proper diagnosis and management of the underlying condition.
