This condition is likely to be a clinical reaction caused by indigestion. If the patient has gastroenteritis, the stimulation of food after eating will cause intestinal spasm to occur and intestinal peristalsis to speed up, so the patient will have stomach pain and want to defecate, timely defecation is a good help to relieve abdominal pain. If the abdominal pain is not relieved for a long time, you can take a little pain medication, do not eat spicy and stimulating food within a short period of time, and eat too little greasy food as much as possible to help relieve the pain. If there is no relief for a long time, the patient may need to go to the hospital for further treatment to determine the diagnosis and effective treatment.
