raised gastrin levels

Last reviewed 01/2018

Some conditions are associated with raised gastrin levels. Examples of causes of marked elevation in gastrin levels include:

• gastrinoma
• small bowel resection
• hypochlorhydria - leads to hyperplasia of the antral gastrin secreting cells and 75% of patients with pernicious anaemia have a marked elevation in gastrin levels

Gastric ulcers may be associated with a mild elevation in gastrin levels. The gastrin level in patients with duodenal ulcers is normal but rises more than normal after a protein meal.
