Have had bright red blood with white/yellow mucous and i digested food with water only coming out as stool. i'm 21. hardly any stool has come out in a?

Red blood in stool: Blood passed rectally is abnormal. In your age bracket hemorrhoids, anal fissure or inflammatory disease of the rectum or colon are possible causes. The presence of mucus is nonspecific but can occur with irritable bowel syndrome as well as inflammatory bowel conditions including an acute infectious process. I think you be examined by a physician or gastroenterologist for diagnosis and treatment.
