Mucus after constipation may be caused by improper diet, viral enteritis, bacterial enteritis, non-specific inflammation and other reasons. 1. Improper diet: avoid eating too greasy food, which cannot be digested and absorbed, resulting in mucus in the stool. 2. Viral enteritis: the intestinal tract is infected by viruses, causing damage to the intestinal mucosa and increasing the secretion of mucus, leading to constipation and then pulling out mucus. 3. Bacterial enteritis: the intestinal tract is infected by bacteria, resulting in inflammatory reaction of the intestinal mucosa and secretion of more mucus, leading to mucus in the stool. 4. non-specific inflammation: including ulcerative colitis, Crohn’s disease, etc., can appear after constipation pulled out of the stool with mucus. If you have mucus after constipation, it is recommended that you consult a doctor to find out the cause and treat it under the doctor’s guidance.
