Other Autoimmune Disorders
The chances of the occurrence of alopecia areata are higher in people who have a family history of one or other autoimmune disorders. Some of the autoimmune disorders which can increase the likeliness of a person having alopecia areata are:
Type 1 diabetes:
In Type 1 diabetes, the immune cells attack the pancreas and disrupt the production of insulin by the pancreatic cells. Diabetes slows downs the hair growth cycle and causes more hair loss. The hair loss is not only from the head but also from other body parts like arms and legs. The condition of alopecia areata arises in diabetes patients and is a more common symptom in a diabetic patient. Diabetes patients also have compromised hair regrowth. The growth rate of hair almost reduces to a slower than average rate. Once diabetes is under control in patients, there is also a reduction in hair loss.
