A week without a bowel movement is usually not very dangerous if it is caused by constipation. If it is caused by intestinal obstruction, the patient needs to seek prompt medical attention. For patients with a history of constipation, if they have not had a bowel movement for a week without obvious discomfort, it is recommended to drink more water, increase exercise and consume more coarse cellulose food to promote intestinal peristalsis, or under the guidance of a doctor, laxative treatment is usually not too dangerous. If the patient usually has normal bowel movement and exhaustion and suddenly appears to have no bowel movement for a week, combined with abdominal pain, abdominal distension, nausea, vomiting, fever and other symptoms, it may indicate acute intestinal obstruction, and the patient must be promptly admitted to hospital for treatment, and there is a certain risk. The frequency of bowel movement for normal adults is 1-2 times a day or once every two days, and some people do not meet this standard but maintain a stable bowel frequency, so there is usually no need to worry. If there is a sudden change in bowel habits or frequency, or if you have not had a bowel movement for more than a week, it is recommended that you visit a gastroenterology clinic for an examination to determine the cause.
