Not having bowel movements for several days or having no bowel movements can be treated by removing the cause, changing the diet, medication such as Mosapride and behavioral modification. 1. Remove the cause: intestinal obstruction, hypothyroidism, intestinal tumors and so on may lead to no bowel movement, but the symptoms of these diseases themselves are different, so you can clarify the cause of the disease through targeted examination, and then treat the cause of the disease, so as to solve the symptom of constipation. 2. Improve dietary habits: lack of fiber-rich fruits or vegetables in the diet can reduce the volume of feces, increase the viscosity of feces, slow down the peristalsis of feces in the intestines, and the water is absorbed too much, which leads to the lack of bowel movement and no bowel movement. Therefore, you need to improve your diet, eat more fiber-rich vegetables and fruits, and drink more water. 3. medication: constipation patients with dry stools, difficult to discharge, can use polyethylene glycol electrolyte bulk and other laxatives to increase the intestinal water, soften stools, promote intestinal peristalsis, thereby promoting defecation. You can also use prokinetic drugs such as mosapride to promote peristalsis in the small intestine and colon. Be careful not to use laxatives and prokinetic drugs frequently. It is important to be aware of the possibility of adverse reactions to the above medications such as abdominal pain, dry mouth, and skin rash. 4. Behavioral modification: Trying to have a bowel movement at a fixed time every day may be helpful for patients with constipation. All of the above medications should be administered under the supervision of a doctor. If constipation persists and does not improve, you should go to the hospital in a timely manner, with the help of a doctor to identify the cause of the disease and carry out targeted treatment.
