Gastrinoma in the early stages will have signs and symptoms of indigestion [3] or similar to irritable bowel disease (IBD) such as: Hypergastrinemia [3] Refractory or recurrent peptic ulcers involving duodenum [3] Chronic diarrhea [7] [2] [3] Generalized cancer symptoms; Abdominal pain [3] Gastrointestinal bleeding [3] Obstruction of intestine [8]
Usually the ulcers are multiple or atypical in location, and often bleed, perforate, or become obstructed. Peptic ulcer disease may be intractable and complicated. Among patients presenting with Zollinger-Ellison syndrome, 20 to 60% have MEN 1. A severe secretory diarrhea can develop and cause fluid and electrolyte depletion with non–β-cell ...
Zollinger–Ellison syndrome (Z-E syndrome) is a rare disease in which tumors cause the stomach to produce too much acid, resulting in peptic ulcers. Symptoms include abdominal pain and diarrhea . The syndrome is caused by the formation of a gastrinoma , a neuroendocrine tumor that secretes a hormone called gastrin . [ 2 ]
[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]
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.
The amoebae inside the cyst are protected from the stomach's digestive acid. From the stomach, the cyst travels to the intestines, where it breaks open and releases the amoebae, causing the infection. The amoebae can burrow into the walls of the intestines and cause small abscesses and ulcers to form. The cycle then begins again. [citation needed]
Another common condition is gastric ulceration, peptic ulcers. Ulceration erodes the gastric mucosa, which protects the tissue of the stomach from the stomach acids. Peptic ulcers are most commonly caused by a bacterial Helicobacter pylori infection. [5] Epstein–Barr virus infection is another factor to induce gastric cancer. [6] [7]
Causes of gastric outlet obstruction include both benign causes, such as peptic ulcer disease affecting the area around the pylorus, and malignant causes, such as gastric cancer. Causation related to ulcers may involve severe pain which the patient may interpret as a heart condition or attack. [1]
