Upper gastrointestinal bleeding (UGIB) is gastrointestinal bleeding in the upper gastrointestinal tract, commonly defined as bleeding arising from the esophagus, stomach, or duodenum. Blood may be observed in vomit or in altered form as black stool. Depending on the amount of the blood loss, symptoms may include shock.
GERD is the most common cause of esophagitis because of the backflow of acid from the stomach, which can irritate the lining of the esophagus. Other causes include: Medicines – Can cause esophageal damage that can lead to esophageal ulcers Nonsteroidal anti-inflammatory drugs (NSAIDS) – aspirin, naproxen sodium, and ibuprofen. Known to ...
[1] [9] Sometimes in those with small amounts of bleeding no symptoms may be present. [1] Bleeding is typically divided into two main types: upper gastrointestinal bleeding and lower gastrointestinal bleeding. [2] Causes of upper GI bleeds include: peptic ulcer disease, esophageal varices due to liver cirrhosis and cancer, among others. [3]
Peptic ulcer disease is a break in the inner lining of the stomach, the first part of the small intestine, or sometimes the lower esophagus. [1] [7] An ulcer in the stomach is called a gastric ulcer, while one in the first part of the intestines is a duodenal ulcer. [1]
The symptoms vary from the severity of the disorder. The most classic sign of AEN is the dark pigmentation of esophageal mucosa in an upper endoscopy, usually viewed as an ulcer or as an infectious disease. [6] Necrosis can be found mostly between the three distals of the esophagus, but stops abruptly at the gastroesophageal junction. [2]
Acid peptic diseases, such as peptic ulcers, Zollinger-Ellison syndrome, and gastroesophageal reflux disease, are caused by distinct but overlapping pathogenic mechanisms involving acid effects on mucosal defense. Acid reflux damages the esophageal mucosa and may also cause laryngeal tissue injury, leading to the development of pulmonary ...
Peptic ulcer. [4] [2] This may be related to Zollinger–Ellison syndrome, which causes severe disease. Vascular malfunctions of the gastrointestinal tract, such as bleeding gastric varices or intestinal varices. [4] Mallory–Weiss syndrome: bleeding tears in the esophagal mucosa, usually caused by prolonged and vigorous retching. [4]
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.
