What causes acute intestinal bleeding?

Acute intestinal bleeding causes include inflammation, vascular lesions, tumors, etc.

1. Inflammation

When intestinal infection occurs, it will cause the protective film on the intestinal surface to fall off, resulting in bleeding, such as bacterial enteritis, intestinal tuberculosis, amebic dysentery, etc.

2. Vascular lesions such

as allergic purpura, systemic lupus erythematosus, hereditary hemorrhagic telangiectasia and other diseases, due to increased vascular permeability or damage, resulting in gastrointestinal mucosal blood vessels are easily stimulated by food and other external bleeding, intestinal vascular lesions, will cause massive bleeding, such as hereditary hemorrhagic telangiectasia, intestinal hemangioma, vascular malformation, etc.

3.

Tumor cells are easy to erode blood vessels, causing erosion or even ulcer, resulting in intestinal bleeding. Such as colon tumor, rectal cancer, etc.
