Despite treatment, re-bleeding occurs in about 7–16% of those with upper GI bleeding. [3] In those with esophageal varices, bleeding occurs in about 5–15% a year and if they have bled once, there is a higher risk of further bleeding within six weeks. [13] Testing and treating H. pylori if found can prevent re-bleeding in those with peptic ...
Fecal incontinence or constipation occurs when there is a problem with normal bowel functioning. This could be for a variety of reasons. The normal defecation pathway involves contractions of the colon which helps mix the contents, absorb water and propel the contents along. This results in feces moving along the colon to the rectum.

Rectal bleeding refers to bleeding in the rectum, thus a form of lower gastrointestinal bleeding. There are many causes of rectal hemorrhage, including inflamed hemorrhoids (which are dilated vessels in the perianal fat pads), rectal varices , proctitis (of various causes), stercoral ulcers , and infections .
Blood in stool looks different depending on how early it enters the digestive tract—and thus how much digestive action it has been exposed to—and how much there is. The term can refer either to melena, with a black appearance, typically originating from upper gastrointestinal bleeding; or to hematochezia, with a red color, typically originating from lower gastrointestinal bleeding.

Bleeding that brings the patient to the physician is a potential emergency and must be considered as such until its seriousness can be evaluated. The goals in managing a major acute gastrointestinal hemorrhage are to treat hypovolemia by restoring the blood volume to normal, to make a diagnosis of the bleeding site and its underlying cause, and ...
A common symptom is a continual urge to have a bowel movement—the rectum could feel full or have constipation. Another is tenderness and mild irritation in the rectum and anal region. A serious symptom is pus and blood in the discharge, accompanied by cramps and pain during the bowel movement.
Ischemic colitis must be differentiated from the many other causes of abdominal pain and rectal bleeding (for example, infection, inflammatory bowel disease, diverticulosis, or colon cancer). It is also important to differentiate ischemic colitis, which often resolves on its own, from the more immediately life-threatening condition of acute ...
SCAD may lead to abdominal pain, especially in the left lower quadrant, intermittent rectal bleeding and chronic diarrhea. [1] The cause of SCAD is unknown, but may be related to local colonic ischemia, fecal stasis, or mucosal prolapse. The factors that cause SCAD likely overlap with inflammatory bowel disease. There are four types of SCAD ...
