Under normal circumstances, the human body will have a thin layer of mucus on the surface of the stool when defecating, when there is an increase in mucus in the stool, it is considered to be caused by diseases such as enteritis. When there is inflammation in the intestinal tract, there will be more secretions leaking out, which will be discharged with the stool, making it easy to show increased mucus in the stool. Long-term poor dietary habits will stimulate the intestinal mucosa, which will affect the digestive function of the intestine, and accompanied by increased leakage of intestinal mucus and other performance, there will also be increased mucus in the stool. Diet often eat meat, high protein, high fat food, glutinous rice and other viscous food, defecation will easily lead to increased performance of stool pus.
