The white mucus excreted is associated with indigestion, constipation, steatorrhea, and ulcerative colitis. People with indigestion have low gastrointestinal digestion of food, which is accompanied by malnutrition, and their feces contain undigested food and are accompanied by white mucus. When constipation occurs, because the stool is too dry, it will cause some stimulation to the intestinal tract, and the intestinal wall will secrete a large amount of mucus to lubricate the intestinal tract to promote the discharge of stool, and the white mucus will be attached to the surface of the stool. In some people, white mucus is associated with small intestine malabsorption syndrome and pancreatitis, which is caused by fatty foods that cannot be digested, decomposed and absorbed by the body. When white mucus is discharged in the stool, accompanied by symptoms such as bloating and diarrhea, and lasts for a long time, you should be alerted to ulcerative colitis, which causes necrosis of the colonic mucosa and is accompanied by the discharge of feces, which discharges white mucus-like material.
