Egg white mucus with blood in the stool may be caused by acute enteritis, ulcerative colitis, intestinal polyps and other reasons. 1. Acute enteritis: the intestinal tract is infected by bacteria, viruses and other pathogenic bacteria, resulting in intestinal mucosal damage, the amount of exudate mucus increases, due to the formation of intestinal mucosal erosion, resulting in bleeding, so there is an egg-white mucus with blood in the stool, accompanied by abdominal pain, diarrhea and other symptoms. 2. Ulcerative colitis: due to long-term inflammation of the intestinal mucosa stimulation caused by ulcers, so the intestinal secretion of mucus is more, egg-white mucus, accompanied by blood, abdominal pain, urgency and heaviness (discomfort in the lower abdomen, want to relieve the stool, after defecation, there is a sense of incomplete defecation) and other symptoms. 3. Intestinal polyps: the mucous membrane of the intestinal tract is elevated and redundant, because when the feces is discharged, the mucous membrane on the surface is exuded and the amount of mucus is increased, so there is egg-white mucus accompanied by blood. Egg white mucus with blood in the stool may also have other causes, it is recommended to consult a doctor in time to identify the cause of the disease, and treat it as soon as possible.
