经常起口腔溃疡是WhatCause导致

The causes of frequent mouth ulcers are varied, primarily including the following aspects: 1. Immune factors: Patients with mouth ulcers often experience decreased cellular immune function and imbalance of T-lymphocyte subsets, which may make the oral mucosa more susceptible to damage. 2. Mental factors: Long-term mental stress, emotional fluctuations, and insufficient sleep may lead to dysfunction of the nervous system, thereby triggering mouth ulcers. 3. Endocrine disorders: Staying up late, unhealthy lifestyle habits, and hormonal changes during a woman's menstrual cycle can all lead to endocrine disorders, thereby increasing the risk of mouth ulcers. 4. Digestive system diseases: Gastrointestinal diseases such as gastric ulcers and duodenal ulcers are closely related to the occurrence of mouth ulcers; these conditions may cause disease by affecting the immune system. 5. Nutritional deficiencies: Deficiencies in nutrients such as B vitamins, folic acid, iron, and zinc are also common causes of mouth ulcers. Insufficient intake of these nutrients can reduce immune function and increase the risk of mouth ulcers.
