Question: what are avms in stomach?
Answer: Upper GI (esophagus, stomach, or duodenum) bleeding is most often due to ulcers. In the small bowel, 30 to 40% of bleeding is caused by abnormal blood vessels in the wall of the small bowel. These abnormal blood vessels have many names, including angioectasias, angiodysplasias, or arteriovenous malformations (AVMs).
