What causes gastritis?

Gastritis develops when anything weakens or injures the mucosa lining of the stomach. The issue may be caused by a variety of factors, including:

• Alcohol abuse: Alcohol abuse can irritate and damage the stomach lining over time.
• Autoimmune disease: Some individuals experience immune system attacks on healthy stomach lining cells.
• Bacterial infection: Peptic ulcer disease (stomach ulcers) and chronic gastritis are mostly brought on by the H. pylori bacteria. Inflammation is brought on by the bacteria’s destruction of the stomach’s barrier lining.
• Bile reflux: To aid in the digestion of fatty foods, the liver produces bile. “Reflux” is a reversal of flow. When bile bypasses the small intestine and instead rushes back into the stomach, this condition is known as bile reflux.
• Physical stress: Gastritis may develop as a result of an unexpected, serious sickness or accident. Gastritis frequently occurs even following trauma to the body that does not affect the stomach. Brain injuries and severe burns are two common causes.
