Other treatments for gastrinomas include:
- chemotherapy (kills cancer cells that can’t be removed surgically)
- proton-pump inhibitors (reduce the production of stomach acid)
What is the treatment for gastrinoma?
The location of tumors, and whether they’ve spread to other parts of the body, determines how your doctor treats gastrinoma. Surgery is the primary treatment, and the objective of surgery is to remove cancer from the body and cure the disease. The procedure your doctor recommends is also based on the location of the tumor.

What happens if your gastrin levels are too high?
It can lead to Zollinger-Ellison syndrome, a disease with very high gastrin levels, stomach and small intestine ulcers, and diarrhea. People with this disease can have gastrin levels as high as 2000 pg/ml [ 14, 17 ].
What does gastrin do for the stomach lining?
But gastrin also helps protect and replenish the cells in the stomach lining [ 1, 2 ]. Gastrin mainly acts by boosting stomach acid production, which helps to digest food. Gastrin is released in the largest amounts by cells in the stomach near the entrance to the small intestine (called antral G-cells).
Why is my gastrin elevated?
Do PPIs elevate gastrin levels?

What happens if you have too much gastrin?
Increased gastrin makes the stomach produce far too much acid. The excess acid then leads to peptic ulcers and sometimes to diarrhea. Besides causing excess acid production, the tumors are often cancerous (malignant).
What causes elevated gastrin?
By far, the two most common causes of high gastrin levels are anti-acid medications you take for reflux or heartburn and a condition called chronic atrophic gastritis. These both can do damage to your stomach lining. They also cause your stomach to make less acid.
What stops gastrin production?
The production and release of gastrin is slowed by the hormone somatostatin, which is released by the pancreas when the stomach empties at the end of a meal, and as well as when there is a drop in the pH levels of the stomach (when the pH of the stomach becomes too more acidic).
Can Zollinger-Ellison syndrome be cured?
Outlook / Prognosis The outlook for people with Zollinger-Ellison syndrome depends on the person. The condition can be cured if the gastrinoma is successfully removed with surgery. If surgery is not possible, in some cases Zollinger-Ellison syndrome can be managed medically.

Abnormal gastrin production occurs in some clinical and diseased states, a condition known as hypergastrinemia and defined by a Gastrin level greater than 100–150 pg/ml [2].
What does a gastrin blood test tell you?
This test measures the amount of gastrin in the blood to help evaluate an individual with recurrent peptic ulcers and/or other serious abdominal symptoms. When food is eaten, the antrum of the stomach becomes distended and the presence of food stimulates the release of gastrin.

The diagnosis of gastrinoma may be suspected in patients with stomach or small intestinal ulcers if they: are resistant to treatment. have recurrent ulcers. have associated complications such as intestinal perforation and bleeding.
Is Zollinger-Ellison syndrome malignant?
The gastrinomas associated with ZES are considered to have malignant potential. Evidence suggests that these malignancies are usually slow growing, although a small percentage may be rapidly invasive. The malignancies most commonly spread to regional lymph nodes and the liver.

Gastrinomas causes severe, unopposed gastrin elevations (>2000 pg/ml, although it can have a wide range of 300–2000 pg/ml) [2]. These tumors are typically multiple and localized to the pancreas (80%) or the duodenal wall (20–30%) [41].
Which receptors are responsible for gastric acid secretion?
There are two established types of gastrin receptors: cholecystokinin (CCK)-A and CCK-B. Circulating gastrin stimulates the CCK-B receptors on the basolateral membrane of the parietal cells, directly causing gastric acid secretion. Gastrin is released by the G cells in response to food intake.

Abstract. Gastrin is an important hormone of the digestive system, which assists gastric acid secretion. It may be pathologically elevated in conditions such as Zo llinger-Ellison syndrome, or due to common medications such as proton pump inhibitors.
Is gastrin a prohormone?

Gastrin stimulates the parietal and pepsin cells, increases gastric mucosal blood flow, and has a trophic effect on the gastric, duodenal and colonic mucosa [3]. Its main roles include food-stimulated gastric acid secretion and trophic effects on the ECL-cells [4, 5].
