[1] With a gastric ulcer, the pain may worsen with eating. [7]
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]
The excess gastric acid causes peptic ulcer disease and distal ulcers. Gastrinomas most commonly arise in the duodenum, pancreas or stomach. [3] In 75% of cases, Zollinger–Ellison syndrome occurs sporadically, while the remaining 25% of cases are due to an autosomal dominant syndrome called multiple endocrine neoplasia type 1 (MEN 1). [4]
Gastric ulcer in antrum of stomach with overlying clot. Pathology was consistent with gastric lymphoma. 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.
Increased gastrin secretion increases gastric acid, which may inactivate pancreatic lipase, leading to diarrhea and steatorrhea. Increased gastrin secretion also leads to peptic ulcers in > 50% of MEN 1 patients. Usually the ulcers are multiple or atypical in location, and often bleed, perforate, or become obstructed.
The ulcer is known initially as a peptic ulcer before the ulcer burns through the full thickness of the stomach or duodenal wall.

[96] In 2012, stomach cancer was the fifth most-common cancer with 952,000 cases diagnosed. [16] It is more common both in men and in developing countries.
Having too little or no gastric acid is known as hypochlorhydria or achlorhydria respectively and are conditions which can have negative health impacts. Having high levels of gastric acid is called hyperchlorhydria. Many people believe [vague] that hyperchlorhydria can cause stomach ulcers. However, recent research indicates that the gastric ...
