What is the reason why oral ulcers always recur

If oral ulcers keep recurring, you should pay attention to whether it is caused by immune deficiency or lack of some trace elements in the body. Also, if you suffer from colitis, chronic or persistent hepatitis, and some patients with gastric ulcers will also show symptoms of oral ulcers repeatedly.

1. The duration of recurrence is closely related to the length of the history of oral ulcers. If the history is short, the disease may occur once every few months or a year; if the history is long, the disease may occur once a month, or new and old lesions of oral ulcers may appear alternately. Generally, it can heal itself in about 10 days without leaving any scars. Recurrent oral ulcers are the most common oral mucosal diseases. They recur repeatedly but are self-limited, and manifest locally as isolated, round or oval ulcers. Clinically, it is divided into three types: recurrent mild oral ulcers, recurrent stomatitis oral ulcers, and recurrent necrotizing mucosal peri-adenitis.

2. Recurrent oral ulcers are closely related to immunity. Some patients show immunodeficiency, while others show autoimmune reactions. That is, due to various factors, the body's normal immune system produces an immune response to its own tissue antigens, causing tissue destruction and the onset of the disease.

3. Secondly, it is related to genetics. In clinical practice, the incidence of recurrent oral ulcers has an obvious familial genetic tendency. We often see that if one or both parents suffer from recurrent oral ulcers, then their children are more likely to get the disease than ordinary people. In addition, the onset of recurrent oral ulcers is often related to some diseases or symptoms, such as digestive system diseases: gastric ulcer, duodenal ulcer, chronic or persistent hepatitis, colitis, etc., as well as anemia, picky eating, indigestion, diarrhea, fever, lack of sleep, excessive fatigue, mental stress, work pressure, changes in menstrual cycle, etc.

4. With the activation, alternation and overlap of one or more factors, the body's immunity is likely to decline and immune function will be disordered, which will cause frequent attacks of recurrent oral ulcers.

5. The typical manifestation of recurrent oral ulcers is that they appear as very fine small spots at the beginning, accompanied by a burning discomfort, and then gradually expand into shallow ulcers with a diameter of 2 to 3 mm or larger. The ulcer is slightly sunken and covered with a layer of light yellow pseudomembrane. The mucosa around the ulcer appears red due to congestion and there is obvious burning pain.

6. The pain becomes more severe when contact with irritating foods. The onset of recurrent oral ulcers is self-limited and cyclical. Generally, recurrent oral ulcers can gradually heal within 7 to 10 days without special treatment. The intervals vary in length, from a few days to several months, and they occur repeatedly one after another.
