How Does Alopecia Areata Affect Other Body Parts?
Alopecia areata, an autoimmune disease characterized by patchy hair loss, can also impact other parts of the body such as the eyelashes, fingernails, or toenails. In fact, changes in the nails can often be one of the first signs of alopecia areata. If you observe your nails becoming rougher, losing their shine, or becoming more prone to splitting, it could indicate an underlying condition. Additionally, alopecia areata can cause the appearance of white spots and lines on the nails, as well as small dents.
Diagnosing Alopecia Areata
Diagnosing alopecia areata is typically straightforward for doctors, who can base their diagnosis on the visible symptoms. A thorough clinical examination is usually conducted, followed by a closer examination of the affected areas using a microscope. In some cases, a skin biopsy may also be performed. Blood testing may be necessary to rule out the presence of other autoimmune diseases. Once the diagnosis is confirmed, treatment can begin promptly.
