If the stomach pain is relieved after defecation, if it is occasional, it may be caused by fecal stimulation of the intestines, which is normal. If frequent, you need to consider whether it is caused by acute enteritis, incomplete intestinal obstruction, intestinal flatulence and other diseases: 1. Acute enteritis: mostly due to eating unhygienic food, or eating spicy, stimulating, cold food, so that the intestines are stimulated and then cause intestinal spasm, which will cause abdominal pain in patients. After defecation, bacteria and toxins are also excreted, and with the reduction of intestinal contents, intestinal pressure is reduced and abdominal pain symptoms are improved; 2, incomplete intestinal obstruction: it is a kind of acute abdominal disease with a mild degree of obstruction, which can also cause abdominal pain and reduce pain after defecation. 3, intestinal flatulence: due to the accumulation of excessive gas in the stomach, patients will feel abdominal distension, belching, and increased anal exhaustion and other symptoms, after defecation, the abdominal pain symptoms can be slightly relieved; some patients will also have other accompanying symptoms, such as abdominal distension, pale skin, etc.; 4, other: such as irritable bowel syndrome, chronic gastroenteritis, etc., can also make patients appear stomach pain after defecation. . There are many causes of abdominal pain, and it is more common that the stomach pain will get better after defecation, so it is recommended to go to a regular hospital for a detailed examination to find the exact cause according to the results of the examination, and to carry out systematic and standardized treatment according to the cause, so as not to delay the disease.
