Gastric ulcers are usually prone to recurrence at the time of autumn and winter, as well as at the time of winter and spring. At this time of the year, the incidence of ulcers increases significantly because of the decrease in blood supply to the stomach due to the change in climate, and the decrease in blood supply to the gastric mucosa leads to a decrease in protective factors of the gastric mucosa, such as a decrease in the mucus barrier and a decrease in the production of bicarbonate. Moreover, ulcers at this time of the year are usually complicated by serious complications, such as bleeding or perforation. If symptoms such as pain in the upper abdomen, acid reflux, belching and bloating occur at this time of the year, one needs to be alert and the patient may consider going to the hospital for a gastroscopy to see if the ulcer has recurred. If there is significant vomiting of blood or black stool, the ulcer is complicated by bleeding. Or if there is a sudden cut-like pain in the upper abdomen, there is a possibility of ulcer perforation, and this time the patient also needs to be hospitalized immediately.
