[13] Disorders such as anxiety, major depression, and chronic fatigue syndrome are common among people with IBS. [1] [14] [note 1] [15] The cause of IBS is not known but multiple factors have been proposed to lead to the condition. [2]
A lower gastrointestinal bleed is defined as bleeding originating distal to the ileocecal valve, which includes the colon, rectum, and anus. [2] LGIB was previously defined as any bleed that occurs distal to the ligament of Treitz, which included the aforementioned parts of the intestine and also included the last 1/4 of the duodenum and the entire area of the jejunum and ileum.

Rectal tenesmus is a feeling of incomplete defecation. [1] It is the sensation of inability or difficulty to empty the bowel at defecation, even if the bowel contents have already been evacuated.

Such conditions include: Crohn's disease, infectious colitis, nonsteroidal anti-inflammatory drug enteropathy, and irritable bowel syndrome. Alternative causes of colitis should be considered, such as ischemic colitis (inadequate blood flow to the colon), radiation colitis (if prior exposure to radiation therapy), or chemical colitis.
Eating beetroot can cause harmless red-colored feces because of insufficient metabolism of a red pigment, and is a differential sign that may be mistaken as hematochezia. Consumption of dragon fruit or blackberries may also cause red or black discoloration of the stool and sometimes the urine (pseudohematuria). This too, is a differential sign ...
