What causes recurrent oral ulcers?

The main causes of frequent oral ulcers include the following points: 1. Genetic factors: Studies have shown that approximately 40% of patients with oral ulcers have a family history, indicating that genetic factors play a certain role in the development of oral ulcers. 2. Immune factors: A weakened immune system makes the body more susceptible to pathogen invasion, leading to the occurrence of oral ulcers. Additionally, the consumption of immune proteins during immune responses may disrupt the immune balance in the oral cavity, thereby accelerating ulcer formation. 3. Dietary factors: Picky eating habits may lead to an imbalanced intake of vitamins (such as B vitamins, vitamin C) and minerals (such as iron, zinc), which are crucial for maintaining oral mucosal health. 4. Psychological factors: Conditions such as high mental stress, significant emotional fluctuations, or long-term insufficient sleep may cause dysfunction of the autonomic nervous system, thereby triggering oral ulcers. If you have any concerns, please consult a relevant healthcare professional.
