Stool with snot-like mucus may be caused by intestinal infection, ulcerative colitis, intestinal tumors and other diseases. 1. Intestinal infection: when the patient’s intestinal tract is infected by bacteria, viruses and other foreign pathogens, it will lead to the secretion of mucus by the patient’s intestinal mucosal cells, which will lead to the mucus in the stool with a snot-like mucus. 2. Ulcerative colitis: when patients have ulcerative colitis, the intestinal mucosa is damaged and congestion and edema occurs, which can lead to an increase in mucus secretion from the mucosa, resulting in mucus stools or mucus-pus-blood stools. 3. Intestinal tumor: when patients have intestinal tumor, the tumor tissue will invade the surrounding tissues, leading to the damage of the mucous membrane of the surrounding tissues, and the mucous membrane cells will secrete mucus; some tumors will secrete a large amount of mucus, which will lead to mucus-like stool. The presence of snot-like mucus in the stool may also be related to other reasons, it is recommended to go to the hospital in time, under the guidance of a professional physician to clarify the cause of the disease, and give targeted treatment or therapy.
