Tummy bowel pain may be caused by peptic ulcer, intestinal obstruction, pancreatitis and other factors. 1. Peptic ulcer: when the mucous membrane of the gastrointestinal tract is damaged, it may lead to the formation of ulcers, and gastric acid and intestinal contents may cause irritation to the ulcers, thus causing pain in the stomach and intestines. 2. Intestinal obstruction: When obstruction occurs in the intestinal tract, the intestinal contents at the upper end of the obstruction site cannot pass through the obstruction site smoothly, thus leading to increased pressure in the intestinal lumen at the upper end of the obstruction site. Under the effect of pressure, stomach and intestinal pain may occur. 3. Pancreatitis: When pancreatitis occurs, pancreatic enzymes may leak out of the pancreatic duct, which may not only cause irritation to the intestinal wall, but also break down local tissues. That’s why stomach and intestinal pain can be caused by pancreatitis. When the situation of stomach bowel pain occurs, you should consult a doctor in time, improve gastroscopy, enteroscopy, CT and other tests under the guidance of the doctor, clarify the cause of the disease, and actively treat it.
