Gastric aspiration and or lavage, where a tube is inserted into the stomach via the nose in an attempt to determine if there is blood in the stomach, if negative does not rule out an upper GI bleed [20] but if positive is useful for ruling one in. [14] Clots in the stool indicate a lower GI source while melana stools an upper one. [14]
Inflammation or cancers of the pancreas may result in a blood clot forming in the splenic vein. As the short gastric veins of the fundus of the stomach drain into the splenic vein, thrombosis of the splenic vein will result in increased pressure and engorgement of the short veins, leading to varices in the fundus of the stomach.

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 ]
Coagulopathy (also called a bleeding disorder) is a condition in which the blood's ability to coagulate (form clots) is impaired. [1] This condition can cause a tendency toward prolonged or excessive bleeding (bleeding diathesis), which may occur spontaneously or following an injury or medical and dental procedures.

Thrombosis (from Ancient Greek θρόμβωσις (thrómbōsis) 'clotting') is the formation of a blood clot inside a blood vessel, obstructing the flow of blood through the circulatory system. When a blood vessel (a vein or an artery) is injured, the body uses platelets (thrombocytes) and fibrin to form a blood clot to prevent blood loss ...
The treatment of intestinal ischemia depends on the cause and can be medical or surgical. However, if bowel has become necrotic, the only treatment is surgical removal of the dead segments of bowel. [34] In non-occlusive disease, where there is no blockage of the arteries supplying the bowel, the treatment is medical rather than surgical ...
Small blood clots—say, dime- or nickel-sized on your heaviest flow days—may appear during menstruation and that’s not uncommon, especially if you feel fine otherwise and you’re not ...
However, the lesions may be widespread, making such treatment impractical. [citation needed] If the bleeding is from multiple or inaccessible sites, systemic therapy with medication may be necessary. First-line options include the antifibrinolytics tranexamic acid or aminocaproic acid. Estrogens can be used to stop bleeding from angiodysplasia.
