Endocrine changes

Some female patients often experience it during menstruation, which may be related to the decrease in estrogen levels in the body. Some women will experience oral ulcers during their menstrual period or before and after their menstrual period. Medication can only provide temporary relief, and the ulcers will reappear during the next menstrual period, causing unbearable pain. At the same time, they are often accompanied by annoying symptoms such as dry mouth, upset, irritability, and dry stools. Clinical studies have found that oral ulcers during menstruation are mainly caused by increased progesterone levels and decreased estrogen (progesterone, etc.) levels in the body.

1. Other factors

Lack of trace elements such as zinc and iron, lack of folic acid, vitamin B12 and malnutrition can reduce immune function and increase the possibility of recurrent oral ulcers. Viruses may be the initiating factors of oral ulcers, but relevant antibodies have not yet been found in patient serum, and there are no reports of isolating viruses from oral ulcer lesion tissues. The role of bacteria in oral ulcers has been proposed for many years. The bacteria closely related to oral ulcers include Streptococcus sanguinis and Helicobacter pylori [14]. The imbalance in the generation and clearance of superoxide free radicals in the body, the imbalance in the ratio of thromboxane B2 and 6-keto-prostaglandins, and the decrease in overall levels can cause oral ulcers. Microcirculation disorders lead to slow blood flow, low blood volume, and dilation of the diameter of the capillary venous end, causing local ischemia and hypoxia, thereby causing mucosal damage and ulcer formation. Serum zinc deficiency, iron deficiency, and high copper content are correlated with the occurrence of RAU. There are reports that quitting smoking can also induce oral ulcers. The ingredient 1,2-sodium sulphate (SLS) in toothpaste may irritate the mucous membrane and induce oral ulcers.

2. Genetic factors

If both parents suffer from recurrent oral ulcers, about 80-90% of their children will suffer from the disease. If one parent has the disease, about 50-60% of their children will suffer from the disease.

Patients with systemic diseases are prone to oral ulcers, mainly by affecting the immune system. Oral ulcers are related to gastric ulcers, duodenal ulcers, ulcerative colitis, regional enteritis, hepatitis, etc. Studies have shown that 30%-48% of patients with oral ulcers have digestive tract diseases, such as abdominal distension, diarrhea or constipation.
