Gastrin: What It Does, How It Affects Digestion, and What You Need to Know
When you eat, your body doesn’t just rely on your stomach to do the work—it uses signals, and one of the most important is gastrin, a hormone produced in the stomach lining that tells acid-producing cells to release hydrochloric acid. Also known as gastric hormone, it’s the main driver behind digestion after a meal. Without gastrin, your stomach wouldn’t break down food properly, and nutrients like protein and iron would pass through undigested.
But gastrin isn’t just about helping you digest. Too much of it can cause problems. High levels are linked to peptic ulcers, open sores in the stomach or small intestine caused by excess acid, especially in a condition called Zollinger-Ellison syndrome. On the flip side, low gastrin can mean poor digestion, bloating, and even nutrient deficiencies over time. It also interacts with other key players like stomach acid, the strong liquid that breaks down food and kills harmful bacteria and gastric secretion, the combined process of acid, enzymes, and mucus released by the stomach. These aren’t isolated systems—they work together. If gastrin is out of balance, the whole digestive rhythm gets thrown off.
Many people don’t realize that medications like proton pump inhibitors (PPIs) can affect gastrin levels. Long-term use can cause the body to overproduce gastrin in response to reduced acid, which might lead to rebound acid reflux when you stop taking them. That’s why some doctors recommend tapering off slowly. It’s also why conditions like chronic atrophic gastritis—where the stomach lining thins over time—can lead to low gastrin and poor digestion, even if you’re eating fine.
The posts below dive into real-world connections: how drugs like Nexium or Zantac influence acid production, how gut health ties into hormone balance, and why some people with persistent heartburn don’t respond to standard treatments because the root cause isn’t just acid—it’s how gastrin is signaling. Whether you’re dealing with unexplained bloating, recurring ulcers, or just want to understand why your stomach behaves the way it does, these articles give you clear, practical answers—not theory, not fluff.
