Four days without bowel movement is usually a sign of constipation, which can be relieved by improving living and dietary habits, medication such as Keselen, lactulose, polyethylene glycol, etc., and surgery. 1. Improve life and diet: patients can eat more food rich in dietary fiber, such as celery, bananas, coarse grains, etc., which can soften the stool and promote intestinal peristalsis. Usually avoid eating cold and spicy food such as chili, quit smoking and drinking, avoid staying up late, drink more water, develop regular bowel habits, and strengthen exercise to improve their physical condition. 2. Medication: patients can use laxative drugs such as Kefir, lactulose, polyethylene glycol to promote the discharge of stools, but such drugs are easy to form a dependence, and long-term use is not recommended; if the patient is accompanied by intestinal flora imbalance, intestinal probiotics such as bifidobacteria; if accompanied by gastrointestinal peristalsis slowing down, you can take moxapril, domperidone and other prokinetic drugs. 3. Surgery: If the patient is caused by intestinal obstruction, intestinal tumors and other diseases, surgical treatment can be considered. If the patient has no bowel movement for four days for a long time or repeatedly, it is recommended to consult a doctor in time to find out the cause of the disease and carry out targeted treatment. Drugs should be taken in strict accordance with the doctor’s instructions, not self-medication, so as not to delay or even aggravate the condition.
