Cause

Various factors cause the intestinal tube to have lesions, resulting in intestinal bleeding. It may be caused by inflammation of the digestive tract itself, mechanical damage, vascular disease, tumor, etc., and may also be caused by lesions of adjacent organs and systemic diseases involving the digestive tract. Intestinal bleeding belongs to lower gastrointestinal bleeding. Common causes of lower gastrointestinal bleeding are: diverticulitis in the lower digestive tract in the diverticulitis accounted for 20% to 55%; vascular dysplasia accounted for 3% to 40%; tumors accounted for 8% to 26%; inflammation accounted for 6% to 22% Benign anorectal diseases account for 9% to 10%.

You can do some checks to aid in the diagnosis:

Fecal color: The determination of stool color can help to initially diagnose the possibility of blood in the stool and help to initially screen patients with upper gastrointestinal bleeding. It is often necessary to combine the fecal occult blood test.

Fecal traits: Fecal trait tests can help diagnose various intestinal diseases. General radiography: general radiography can be taken on the skull, chest, abdominal plain, bones and joints of the limbs. The film plays an important role in the diagnosis work.

Differential diagnosis

Should pay attention to distinguish: digestive tract bleeding is divided into upper digestive tract and lower digestive tract, the upper digestive tract is generally vomiting blood, so the gastroscope can not be checked. Duodenal hemorrhage is generally characterized by melena, especially the degenerative changes in the digestive function of the elderly. The color of small intestine hemorrhage is mostly brown, and the bleeding in the colon is generally dark red, which is determined according to the length of digestion. The bleeding in the rectum is not digested, so the color is bright red.
