The acid in your stomach is strong enough to damage your stomach. So, your stomach lining secretes mucus to protect itself.
Chronic gastritis occurs when your stomach lining becomes inflamed. When inflammation occurs, your stomach lining changes and loses some of its protective cells.
Bacteria (Helicobacter pylori), consuming too much alcohol, certain medications, chronic stress, or other immune system problems can lead to inflammation.
Because chronic gastritis occurs over a long period of time it gradually wears away at your stomach lining.
Research found that the combination of wheat peptides and fucoidan intervention reduced gastric mucosal damage in 70% participants.
Significantly less stomach pain, belching, bloating, acid reflux, loss of appetite, increased food intake, and promoted life quality were reported in the study.
