Alopecia areata is a medical condition in which you tend to lose hair from some, or almost all areas of your body. Most often the hair on the scalp is lost in patches due to which this condition is also known as spot baldness. The bald patches appear all of a sudden and are mostly limited to certain areas. The hair loss may not be permanent and the hair grows back within a year or so. Some people may suffer from severe alopecia aerata and in this case it may cause total baldness.
Almost 60% people affected with alopecia aerata show hair loss before the age of 20. New hair may grow in the old patches, but the problem may be recurring and new bald spots may keep forming. Different types of treatments are available for alopecia aerata, but each one may work differently in each person. Given here are some of the most common causes of alopecia aerata, which is generally considered an autoimmune disorder.
Common Causes Of Alopecia Aerata
People suffering from stress at work, due to a disease or surgery, trauma, etc. are more likely to develop alopecia aerata. Research studies have associated a link between stress and alopecia aerata.
Stress can lower your body’s immunity and lead to autoimmune disorders, which may cause alopecia aerata. That is why it is very important to learn stress reduction techniques if you are undergoing problems at work or in your personal life.
It is observed that people who suffer from allergic conditions like asthma and hay fever may develop alopecia aerata. These conditions can bring down the immunity of the body and result in an autoimmune reaction, thus causing alopecia aerata in the affected person. The amount of hair loss depends on the extent to which a person suffers from allergies. Use of excessive chemicals on the hair can also cause allergic reactions and lead to the development of alopecia aerata.
Thyroid disorders can also cause alopecia aerate. While hyperthyroidism can lead to thinning of hair, hypothyroidism is the main cause behind alopecia aerate. Your metabolism is likely to slow down due to hypothyroidism, and the decreased blood flow to the hair follicles can result in loss of hair causing bald patches. This condition can be reversed using proper care and medications.
It is observed that the development of alopecia aerata in people under the age of 30 is usually caused by genetic factors. This condition seems to run in families, and if even one family has been diagnosed with alopecia aerata, the future generations tend to inherit this condition. A hormone called dihydrotestosterone (DHT) affects the way our hair follicles develop and this seems to be programmed in our genes.
Diabetes is one of the main causes of alopecia aerata. Your immune system gets weakened due to diabetes and your chances of developing alopecia aerata become higher.
The stress you suffer from due to diabetes can also lead to excessive hair fall and the development of alopecia aerata. Also, the medications used for the treatment of diabetes can stress your body and cause alopecia aerata.
