What is the reason for itching around the belly button

Many people easily find that the area around their belly button is always itchy. In fact, this may be a symptom of neurodermatitis caused by not paying attention to it. Of course, it may also be due to emotional fluctuations caused by some mental factors, and excessive mental tension may cause an allergic reaction in the local skin.

Navel itching may be neurodermatitis or itch point syndrome, which is a neurosis. Neurodermatitis is a localized skin nerve dysfunction skin disease also called chronic simple lichen. Traditional Chinese medicine calls it "psoriasis" or "collar sore" because it often occurs on the neck and looks like the skin of a cow's neck, which is thick and tough. As "The Authentic Surgery" says: "Psoriasis is like the skin of a cow's neck, stubborn and hard, and must be scratched like rotten wood." The clinical characteristics are lichenification of the skin, hypertrophy, roughness, severe itching, slow course of the disease, repeated attacks, often not healing for years, and easy relapse after recovery.

1. Neuropsychiatric factors: Due to emotional fluctuations, excessive excitement, depression, tension, anxiety, fear or neurasthenia, the regulatory function of the cerebral cortex is disturbed, causing dysfunction of the nerves around the anus. When stimulated, the skin is prone to react with lichenoid changes.

2. Stimulant factors: Excessive drinking of alcohol, coffee and other spicy stimulants, taking certain drugs that act on the nervous system, and local stimulation such as friction and scratching of underwear are all triggers.

3. Disease factors: Digestive system diseases, endocrine disorders, etc. are also important causes.
