Bleeding in the stomach and intestines, edema, dilated blood vessels. Gastric antral vascular ectasia (GAVE) is an uncommon cause of chronic gastrointestinal bleeding or iron deficiency anemia. [1][2] The condition is associated with dilated small blood vessels in the gastric antrum, which is a distal part of the stomach. [1]
Gastrointestinal bleeding. Gastrointestinal bleeding (GI bleed), also called gastrointestinal hemorrhage (GIB), is all forms of bleeding in the gastrointestinal tract, from the mouth to the rectum. [9] When there is significant blood loss over a short time, symptoms may include vomiting red blood, vomiting black blood, bloody stool, or black ...
1.5% of gastrointestinal bleeding. Dieulafoy's lesion (French: [djølafwa]) is a medical condition characterized by a large tortuous artery [2] most commonly in the stomach wall (submucosal) that erodes and bleeds. It can present in any part of the gastrointestinal tract. [3] It can cause gastric hemorrhage [4] but is relatively uncommon.
Intestinal ischemia is a medical condition in which injury to the large or small intestine occurs due to not enough blood supply. [2] It can come on suddenly, known as acute intestinal ischemia, or gradually, known as chronic intestinal ischemia. [1] The acute form of the disease often presents with sudden severe abdominal pain and is ...
A lower gastrointestinal bleed is defined as bleeding originating distal to the ileocecal valve, which includes the colon, rectum, and anus. [2] LGIB was previously defined as any bleed that occurs distal to the ligament of Treitz, which included the aforementioned parts of the intestine and also included the last 1/4 of the duodenum and the entire area of the jejunum and ileum.

Superior mesenteric artery (SMA) syndrome is a gastro - vascular disorder in which the third and final portion of the duodenum is compressed between the abdominal aorta (AA) and the overlying superior mesenteric artery. This rare, potentially life-threatening syndrome is typically caused by an angle of 6–25° between the AA and the SMA, in ...
Gastric varices. Gastric varices are dilated submucosal veins in the lining of the stomach, which can be a life-threatening cause of bleeding in the upper gastrointestinal tract. They are most commonly found in patients with portal hypertension, or elevated pressure in the portal vein system, which may be a complication of cirrhosis.
Upper gastrointestinal bleeding can be caused by peptic ulcers, gastric erosions, esophageal varices, and rarer causes such as gastric cancer. The initial assessment includes measurement of the blood pressure and heart rate, as well as blood tests to determine the hemoglobin. Significant upper gastrointestinal bleeding is considered a medical ...
