Almost a year after having surgery for early gastric lesions, the stomach sometimes hurts, which may be caused by indigestion or intestinal spasms. 1. Indigestion: If you have undergone surgery for early gastric lesions, the digestive function of the gastrointestinal tract may be affected to a certain extent, and if you eat some indigestible food for a long time, such as chili peppers, mustard oil, etc., it may cause pain in the stomach sometimes. 2. Intestinal spasm: when the abdomen is cold or constipation, it may lead to transient ischemia or hypoxia of the intestinal tract, which may cause intestinal spasm and lead to pain in the stomach. After having surgery for early gastric lesions, if there is pain in the stomach sometimes, it is recommended to go to the hospital as soon as possible for review.
