What is the matter with stomach pain after eating, stomach pain after eating, first of all, we must distinguish the part of the stomach pain, the most common is the pain in the upper abdomen, this pain may be related to peptic ulcer, gallbladder and pancreatic diseases. Usually pain after a full meal, we most commonly see patients with gastric ulcer who have acid reflux, heartburn, periodic, regular epigastric pain, and stomach pain after a full meal or a greasy meal, accompanied by radiating pain in the back of the shoulder, we also need to exclude whether there are some gallbladder lesions such as cholecystitis and gallstones. The pancreas is an important organ that secretes pancreatic fluid. If the stomach pain after eating is pain in the upper left abdomen and the pain is continuously increasing, we should rule out the possibility of pancreatitis. If the stomach pain after eating is mainly in the lower abdomen, we should rule out whether there are some lesions in the small intestine and large intestine, and also care whether the patient is accompanied by abnormal stools, whether the exhaustion is increased, whether the stools are formed, etc. In short, if there is often stomach pain after eating, we suggest that the patient should go to the hospital for timely symptomatic diagnosis and treatment to clarify the cause of abdominal pain.
