Hardness around the stomach should be considered whether it is caused by physiological structure or abdominal tumor, digestive perforation, constipation. 1. Physiological structure: for example, people who like sports and fitness have well-developed abdominal muscles, so it is a normal phenomenon that the stomach is hard around the palpation. 2. Abdominal tumors: such as localized large tumors in the abdominal cavity, it is hard around the belly during palpation. Treatment should be resection of tumor and combined with postoperative radiotherapy. 3. Digestive tract perforation: leading to acute diffuse peritonitis, there may be a plate-like abdomen, i.e., hard on palpation, but accompanied by pressure pain and rebound pain at the same time. 4. Constipation: most common in elderly patients, gastrointestinal function is weakened, a large amount of feces blocked in the intestinal canal, hard lumps can be touched on palpation. Treatment can be given oral lactulose to promote defecation. If the above symptoms occur, they should go to the general surgery department in time and standardize the treatment according to the doctor’s instruction.
