The etiology of mouth ulcers is still unclear, usually the result of a combination of factors, mainly including immune factors, genetic factors, systemic disease factors, infectious factors, environmental factors.
1. Immunological factors: the immunological etiology of ulcers is dominated by cellular immunity, and relevant studies have shown that ulcer patients have decreased cellular immunity and imbalance of T-lymphocyte subpopulations.
2. Genetic factors: relevant studies have shown that the development of ulcers has a genetic predisposition.
3. Systemic disease factors: relevant studies have found that the occurrence of ulcer is closely related to gastric ulcer, duodenal ulcer, ulcerative colitis, restrictive enteritis, liver and gallbladder diseases, and various digestive diseases or dysfunctions caused by parasites.
4. Infectious factors: Although some evidence of infections such as Helicobacter pylori, herpes simplex virus and human papillomavirus have been found in the lesions of patients with ulcers, the etiology of the disease needs to be further explored, so it is still controversial whether infections are the cause of ulcers.
5. Environmental factors: relevant research results show that the type of patient’s behavior, life events and psychological reactions caused by the work environment, food additives and nutritional imbalance, as well as the pace of life and habits of life and other environmental and social factors have a certain relationship with the occurrence of ulcers.
When the mouth ulcers should be timely to the regular hospital, the professional doctor examination after a clear diagnosis, to take appropriate treatment measures to avoid the development of the disease.
