  2. Hematemesis - Wikipedia

    en.wikipedia.org/wiki/Hematemesis

    Hematemesis is treated as a medical emergency. [7] [10] The most vital distinction is whether there is blood loss sufficient to cause shock. Correct management is required in such conditions. It is required to perform all tests such as endoscopy before medication. A platelet test is also an important test in such conditions.

  3. Gastrointestinal bleeding - Wikipedia

    en.wikipedia.org/wiki/Gastrointestinal_bleeding

    An upper source is characterised by hematemesis (vomiting up blood) and melena (tarry stool containing altered blood). About half of cases are due to peptic ulcer disease (gastric or duodenal ulcers). [3] Esophageal inflammation and erosive disease are the next most common causes. [3]

  4. Upper gastrointestinal bleeding - Wikipedia

    en.wikipedia.org/wiki/Upper_gastrointestinal...

    Depending on the amount of the blood loss, symptoms may include shock. 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.

  5. Intestinal ischemia - Wikipedia

    en.wikipedia.org/wiki/Intestinal_ischemia

    There are four mechanisms by which poor blood flow occurs: a blood clot from elsewhere getting lodged in an artery, a new blood clot forming in an artery, a blood clot forming in the superior mesenteric vein, and insufficient blood flow due to low blood pressure or spasms of arteries. [3] [6] Chronic disease is a risk factor for acute disease. [7]

  6. Vomiting - Wikipedia

    en.wikipedia.org/wiki/Vomiting

    The content of the vomitus (vomit) may be of medical interest. Fresh blood in the vomit is termed hematemesis ("blood vomiting"). Altered blood bears resemblance to coffee grounds (as the iron in the blood is oxidized) and, when this matter is identified, the term coffee-ground vomiting is used.

  7. Internal bleeding - Wikipedia

    en.wikipedia.org/wiki/Internal_bleeding

    Internal bleeding (also called internal haemorrhage) is a loss of blood from a blood vessel that collects inside the body, and is not usually visible from the outside. [1] It can be a serious medical emergency but the extent of severity depends on bleeding rate and location of the bleeding (e.g. head, torso, extremities).

    For certain groups of people, “there's research to show that sleep position certainly matters,” says McPhillips. People with obstructive sleep apnea, for example, should sleep on their side or ...

  9. Lower gastrointestinal bleeding - Wikipedia

    en.wikipedia.org/wiki/Lower_gastrointestinal...

    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.
