What are the possible causes of gastrointestinal bleeding?

There are many reasons for gastrointestinal bleeding, including the following. The first is digestive tract inflammation, such as peptic ulcer, inflammatory bowel disease, intestinal tuberculosis and so on. Second, mechanical injuries, such as esophageal foreign bodies, some of which are better than others, and second, vascular diseases, such as esophageal varices, ruptured bleeding and vascular malformation; The other is tumors, such as gastric cancer and colon cancer, which can cause gastrointestinal bleeding. Others are caused by pathological changes in neighboring organs. We must pay special attention to the fact that systemic diseases can also cause gastrointestinal bleeding.
