In colitis, the mucosal cells of the intestine are edematous and degenerated, and the permeability of the mucosa increases, so that more proteins and other macromolecules can infiltrate into the intestinal lumen. These leukocytes and protein components that infiltrate into the intestinal lumen cannot be absorbed by the colon, so they can gather and form mucus-like changes under the action of bacteria in the intestine. If you have mucus stools, you should do further routine stool examination, stool culture and colonoscopy if necessary, and analyze the type of colitis, which can be treated with drugs such as haloperidol and ulcerative colitis with liubizine.
