Bowel obstruction can happen to anyone, but people with chronic constipation, tumors in the gastrointestinal tract, and a history of abdominal surgery are more likely to develop bowel obstruction. Any obstruction to the passage of intestinal contents, regardless of the cause, is called an obstruction. Bowel obstruction is a type of surgical emergency and can happen to anyone, but people with chronic constipation, tumors in the gastrointestinal tract, and a history of abdominal surgery are more likely to develop bowel obstruction than normal people. Chronic constipation and tumors in the gastrointestinal tract can lead to fecal obstruction and intestinal obstruction; people who have had surgery on the gastrointestinal tract are more likely to develop adhesive intestinal obstruction. Intestinal obstruction can cause changes in the form and function of the intestinal tube, and can also cause a series of pathophysiological changes, which can be life-threatening in severe cases. If abdominal pain occurs, the anus stops defecation and other signs of intestinal obstruction, you should consult a doctor immediately.
