My hair suddenly became bald in a small area

Staying up late, working overtime, and rushing to finish work seem to be the most common phenomena for modern people. The work pressure is high and the competition is very fierce. Many people have irregular lives and diets, and some people often overeat, which leads to hair loss in some people. For example, someone suddenly has a small bald spot, which is actually what we often call alopecia areata. Therefore, we must develop good living habits and go to bed early and get up early.

What disease is alopecia areata a precursor to?

1. Mental factors

The main cause of alopecia areata is due to neurological factors. After years of research by relevant experts, it has been found that a large part of the cause of alopecia areata is due to long-term mental anxiety or stimulation and environmental changes. The main cause of alopecia areata is due to neural factors, but ultimately it is more closely related to neural factors, and is generally caused by disorders of the autonomic nervous system or central nervous system.

2. Endocrine abnormalities

Alopecia areata is common among patients with thyroid disease, and is more closely related to hyperthyroidism. Alopecia areata often heals itself during pregnancy, but hair loss may recur after delivery, which is related to hormones.

3. Weak immune function

Many diseases caused by immune system disorders, such as vitiligo vulgaris, diabetes, pernicious anemia, lupus erythematosus, ulcerative colitis, idiopathic hypothyroidism, etc., are often accompanied by the occurrence of alopecia areata. Some French experts have found that the white blood cell immune function in the peripheral blood vessels of patients with alopecia areata is low and often combined with autoimmune diseases. Experts have found that the number of T lymphocytes in the peripheral blood vessels of patients with alopecia areata is significantly reduced, and it is a system that plays an important role in the body's cellular immune function.

4. Lesion infection

Clinical research by medical experts has found that focal infection can indeed cause baldness, because infection by bacteria and other factors can cause thrombosis in blood vessels or inflammation of small blood vessels, causing hair loss in the area they control due to obstruction of blood supply. Clinical research by medical experts in China has found that the presence of impacted third molars or periapical infection can easily cause persistent alopecia areata.

5. Poor blood circulation to the scalp

Some experts have found clinically that if a craniotomy is performed or the skull is not configured properly to match the scalp, the scalp will be too tense, which will cause poor local blood flow, causing the hair to fall out easily due to insufficient nutrition and blood supply, and hair loss is easy to occur from the forehead hairline to the top of the head.

In short, in life, everyone must pay more attention to their own skin health problems, especially to understand the symptoms and clinical manifestations of some skin diseases, so as to detect and treat them early. I hope this article can help you.
