Lack of vitamins and trace elements
The lack of trace elements in the body will cause the decline of immunity, and at the same time, it will also cause various diseases, such as the lack of vitamins, zinc and iron in the body, which will easily lead to oral ulcers. You should eat more fresh vegetables and fruits in your diet and supplement more vitamins.
Mental stress
Due to the accelerated pace of modern people's life, the pressure from life and work will be greater, which will naturally affect their own immunity and endocrine regulation, which will lead to oral ulcers or other diseases. Don't give yourself too much pressure at ordinary times, learn to decompress yourself and pay attention to the combination of work and rest.
Gastrointestinal diseases
Such as chronic gastritis, gastric ulcer, constipation, hemorrhoids, etc., affect the body's absorption of vitamins. If the body has symptoms such as indigestion, gastric ulcer or abdominal distension, those toxic substances can't be eliminated in time, which will naturally lead to oral ulcers. Avoid indigestion or stomach diseases, and pay attention to diet care.
Hormone fluctuation
Individual women will have oral ulcers before and after menstruation, which is mainly caused by the increase of progesterone level and the decrease of estrogen level in the body.
Immune system disorder or immune deficiency
