No bowel movement for 5 days may be related to constipation, gastrointestinal dysfunction and intestinal obstruction, etc., which can be relieved by dietary adjustment, medication and surgery. 1. Constipation: the main symptoms are prolonged absence of defecation, dry stools, difficulty in defecation, etc. It can be treated by increasing water intake, adjusting diet and moderate exercise. If the symptom is serious, you can take senna or external use of drugs such as Keselen. 2. Gastrointestinal dysfunction: gastric ulcer, functional dyspepsia and other diseases can lead to digestive dysfunction, which in turn causes slow intestinal peristalsis and prolonged absence of bowel movement. It can be treated by adjusting diet, correcting bad eating habits and diet structure, and applying drugs such as omeprazole, mosapride and aluminum hydroxide when necessary. 3. Intestinal obstruction: the main symptom is prolonged absence of defecation and gas, which can be treated by fasting and gastrointestinal decompression. If the condition is serious, surgery can be considered. The above drugs are prohibited for those who are allergic to them, and they should be taken in accordance with medical advice. If the patient’s constipation symptoms are serious or persist without improvement, it is recommended to go to a regular hospital in time, after clarifying the cause of the disease, under the guidance of the doctor for targeted treatment.
