Abnormal defecation after temporary stoma return for rectal cancer usually manifests as increased frequency of stool or occurrence of mild diarrhea, which can be treated with medication and adjusted through diet. Rectal cancer surgery is to remove a part of the rectum, resulting in a reduction of a part of the intestinal capacity for storing feces. Since most of the water secreted by feces is absorbed through the rectum, the reabsorption of fecal water is insufficient, which may easily lead to an increase in the number of stools, and mild diarrhea symptoms may occur. These symptoms usually disappear slowly for a period of time after the surgery. If they are not tolerated, medication and dietary adjustments can be taken. 1. Medication: Under doctor’s instruction, medicines such as Montelukast, Loperamide hydrochloride, Bifidobacterium capsule can be used to relieve the symptoms of frequent bowel movements and mild diarrhea, and at the same time, rehydration can be carried out to prevent dehydration caused by diarrhea. 2. Dietary adjustments: Eat a balanced diet, low-fat, easy-to-digest foods. Avoid eating foods that produce much residue and too much fiber, which are easy to stimulate the rectum and not conducive to recovery. After rectal cancer surgery, it takes a period of time to recover, patients can adjust their living and dietary habits and have regular rechecks, which can help promote recovery.
