Causes of oral ulcer

1, digestive system diseases and dysfunction

People with some digestive system problems are prone to oral ulcers, mainly due to the decline of immune system, which leads to ulcers. Many people with oral ulcers will have some digestive problems such as abdominal distension and constipation. For those with poor digestion, we must pay attention to these problems.

2. Endocrine changes

Endocrine conditions can also lead to the occurrence of oral ulcers. Generally, during the menstrual period of women, the endocrine in the body will change, which is easy to cause oral ulcers. The oral ulcers in women during menstrual period are mainly caused by the increase of progesterone levels in the body and the decrease of estrogen (progesterone, etc.).

3. Mental factors

Some people get sick under the condition of mental stress, mood fluctuation and poor sleep condition, which is related to autonomic nerve dysfunction.

4. Genetic factors

If both parents suffer from recurrent oral ulcer, about 80-90% of their children are sick, and if one parent suffers from this disease, about 50-60% of their children are prone to it.

5. Other factors

Lack of trace elements such as zinc, iron, folic acid, vitamin B 12, malnutrition, etc. can reduce immune function and increase the possibility of recurrent oral ulcer. Virus may be the initial cause of oral ulcer. Bacteria closely related to oral ulcers are Streptococcus sanguis and Helicobacter pylori. The imbalance of the generation and clearance rate of superoxide radicals in the body, the imbalance of the ratio of thromboxane B2 to 6-ketoprostaglandin and the decline of the overall level can cause oral ulcers. Microcirculatory disturbance leads to slow blood flow and low blood flow, and the diameter of capillary vein end expands, resulting in ischemia and hypoxia, which leads to oral mucosal injury. There is a certain correlation between zinc deficiency, iron deficiency and high copper in serum.

How to prevent oral ulcer

1. tooth cleaning

People should go to the hospital to wash their teeth regularly in their daily lives, which is a very important dental care method, usually once every six months to once a year. If they are patients with periodontal disease, systematic periodontal treatment is needed.

2. Pay attention to oral hygiene and health.

A good oral hygiene environment can reduce the growth of bacteria in the oral cavity, prevent the accumulation of food residues and cause oral infection. Therefore, in daily life, we should develop the habit of brushing our teeth in the morning and evening and gargling after meals, and brushing our teeth for no less than three minutes at a time. We can also gargle with salted boiled water or normal saline to clean oral hygiene.

3. Pay attention to vitamin intake

Friends with gastrointestinal diseases are more likely to cause oral ulcers than ordinary people. This is because the gastrointestinal tract is the key organ that affects the absorption of vitamins, and vitamins can effectively prevent and reduce the onset of oral ulcers. Therefore, we should try to eat more fruits and vegetables, which are rich in cellulose, and keep the stool unobstructed, which is very important for the prevention of oral ulcers.

4. light diet

People should eat more light dishes in their daily life, and don't eat heavy and irritating food. Drink more water, eat more cellulose-rich foods and keep the stool unobstructed, which can effectively reduce the onset of oral ulcers.

5. Vitamin food

Eating more foods rich in vitamin b 1, vitamin b2 and vitamin C is beneficial to ulcer healing. Therefore, you should eat more fresh vegetables and fruits, such as tomatoes, eggplant, carrots, white radishes, Chinese cabbage, spinach and so on.

6. Avoid eating irritating food

Such as cigarettes, wine, coffee and stimulating drinks.
