Definition & Meaning of "autoimmune gastritis"

What is "autoimmune gastritis"?

Autoimmune gastritis is a condition where the body's immune system mistakenly attacks the cells in the lining of the stomach, leading to inflammation and damage. This can result in reduced production of stomach acid and a substance important for absorbing vitamin B12, which is needed for the production of healthy red blood cells. Symptoms may include stomach discomfort, bloating, nausea, vomiting, and fatigue. Over time, autoimmune gastritis can lead to problems like low red blood cell count and a lack of certain nutrients in the body. Treatment usually involves managing symptoms and addressing any vitamin B12 shortage through supplements and changes to the diet. In some cases, medications to reduce inflammation or suppress the immune system may be used. Regular check-ups with a healthcare provider are important to prevent problems and manage the condition properly.
