Alopecia Areata Causes

Alopecia Areata Causes: Essential Facts

Alopecia areata is a disease whereby the sufferer loses his or her and bald patches appear on the head due to unmanageable hair loss. It would not be inappropriate to say that the patient ‘mysteriously’ loses the hair. It’s valid because the researchers have been trying to work out the link between the outbreaks of this disease with its possible foundation. Studies carried out by scientists are still unable to divulge the alopecia areata causes.

Despite the absence of any concrete evidence regarding the alopecia areata causes, certain hypotheses are nonetheless present. The research is being conducted for the acceptance or rejection of these tentative statements. However, there are few components discovered that provide a supposed relationship between the disease and its causes.
Genetic aspects are considered to be quite significant in this regard. It is suggested that there could be hereditary link for causation of alopecia areata. It is not confirmed that how or which specific genetic code triggers this situation. Nonetheless, it has been monitored that there is a greater rate of alopecia areata recurrence in case of family history with this disease. Such category of patients is also more vulnerable to a severe form of alopecia areata too.

While heredity is a possible determinant for the basis of alopecia areata, there are facts supporting the role of anomalous immune system. This irregularity culminates into a condition called autoimmunity. It means that the chemical substances named cytokines are released by the immune system and the resistance of the immune system increases abnormally. Consequently, the defense cells of body assault certain tissues. In case of alopecia areata, the body’s personal immune system lashes out on the hair follicles and interrupts the regular hair growth. It stimulates the hair loss in a patient from head and other parts of body in form of patches. The biopsy results of the bald scalp shows the presence of immune components that are normally not present in case of a healthy person. The big question mark in this case is that it is not yet figured out what makes immune cells to work this way. The discovery of autoimmunity mechanism is so far the greatest breakthrough in finding out alopecia areata causes.

The other autoimmune diseases include vitiligo, diabetes, rheumatoid arthritis, allergic reactions, thyroid disorder etc. Reportedly, the patients suffering from these health problems are known to be more prone towards having alopecia areata. Even when there is not solid proof for this notion, the trend reveals that people with the family history of autoimmune disorders are relatively more at risk.
