 Most people with ulcerative colitis have mild to moderate symptoms. The course of ulcerative colitis may vary, with some people having long periods when it goes away. This is called remission. Types Health care providers often classify ulcerative colitis according to its location. Symptoms of each type often overlap. Types of ulcerative colitis include: 
Ulcerative proctitis. Inflammation is confined to the area closest to the anus, also called the rectum. Rectal bleeding may be the only sign of the disease.
Proctosigmoiditis. Inflammation involves the rectum and sigmoid colon — the lower end of the colon. Symptoms include bloody diarrhea, abdominal cramps and pain, and an inability to move the bowels despite the urge to do so. This is called tenesmus.
Left-sided colitis. Inflammation extends from the rectum up through the sigmoid and descending portions of the colon. Symptoms include bloody diarrhea, abdominal cramping and pain on the left side, and urgency to defecate.
Pancolitis. This type often affects the entire colon and causes bouts of bloody diarrhea that may be severe, abdominal cramps and pain, fatigue, and significant weight loss.
