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 ...
Despite treatment, re-bleeding occurs in about 7–16% of those with upper GI bleeding. [3] In those with esophageal varices, bleeding occurs in about 5–15% a year and if they have bled once, there is a higher risk of further bleeding within six weeks. [13] Testing and treating H. pylori if found can prevent re-bleeding in those with peptic ...
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 ]
A blood smear, peripheral blood smear or blood film is a thin layer of blood smeared on a glass microscope slide and then stained in such a way as to allow the various blood cells to be examined microscopically. Blood smears are examined in the investigation of hematological (blood) disorders and are routinely employed to look for blood ...
A portacaval anastomosis or portocaval anastomosis is a specific type of circulatory anastomosis that occurs between the veins of the portal circulation and the vena cava, thus forming one of the principal types of portasystemic anastomosis or portosystemic anastomosis, as it connects the portal circulation to the systemic circulation, providing an alternative pathway for the blood.
A nosebleed, also known as epistaxis, is an instance of bleeding from the nose. [1] Blood can flow down into the stomach, and cause nausea and vomiting. [8] In more severe cases, blood may come out of both nostrils. [9] Rarely, bleeding may be so significant that low blood pressure occurs. [1]
Bleeding, hemorrhage, haemorrhage or blood loss is blood escaping from the circulatory system from damaged blood vessels. [1] Bleeding can occur internally , or externally either through a natural opening such as the mouth , nose , ear , urethra , vagina or anus , or through a puncture in the skin .
Intracranial hemorrhage is a serious medical emergency because the buildup of blood within the skull can lead to increases in intracranial pressure, which can crush delicate brain tissue or limit its blood supply. Severe increases in intracranial pressure (ICP) can cause brain herniation, in which parts of the brain are squeezed past structures ...
