A number of medications increase the risk of bleeding including NSAIDs and SSRIs. SSRIs double the rate of upper gastrointestinal bleeding. [4] There are many causes for upper gastrointestinal hemorrhage. Causes are usually anatomically divided into their location in the upper gastrointestinal tract. [citation needed]
Blood in stool looks different depending on how early it enters the digestive tract—and thus how much digestive action it has been exposed to—and how much there is. The term can refer either to melena, with a black appearance, typically originating from upper gastrointestinal bleeding; or to hematochezia, with a red color, typically originating from lower gastrointestinal bleeding.

An upper GI bleed is more common than lower GI bleed. [2] An upper GI bleed occurs in 50 to 150 per 100,000 adults per year. [8] A lower GI bleed is estimated to occur in 20 to 30 per 100,000 per year. [2] It results in about 300,000 hospital admissions a year in the United States. [1] Risk of death from a GI bleed is between 5% and 30%.
Most individuals with G6PD deficiency are asymptomatic.When it induces hemolysis, the effect is usually short-lived. [5]Most people who develop symptoms are male, due to the X-linked pattern of inheritance, but female carriers can be affected due to unfavorable lyonization or skewed X-inactivation, where random inactivation of an X-chromosome in certain cells creates a population of G6PD ...
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 ]
Gastritis is the inflammation of the lining of the stomach. [1] It may occur as a short episode or may be of a long duration. [1] There may be no symptoms but, when symptoms are present, the most common is upper abdominal pain (see dyspepsia). [1]
Melena is a form of blood in stool which refers to the dark black, tarry feces that are commonly associated with upper gastrointestinal bleeding. [1] The black color and characteristic strong odor are caused by hemoglobin in the blood being altered by digestive enzymes and intestinal bacteria.
Iatrogenic anemia, also known as nosocomial anemia or hospital-acquired anemia, is a condition in which a person develops anemia due to medical interventions, most frequently repeated blood draws. [ 1 ] [ 2 ] [ 4 ] Other factors that contribute to iatrogenic anemia include bleeding from medical procedures and dilution of the blood by ...
