What is Autoimmune gastritis?

Autoimmune gastritis is a chronic inflammatory condition in which the immune system mistakenly attacks the stomach lining, leading to damage and loss of gastric cells. This can result in reduced acid production and impaired absorption of nutrients, particularly vitamin B12, leading to potential complications such as anemia. Symptoms may include abdominal pain, nausea, and digestive issues. Long-term effects can increase the risk of gastric cancer and other gastrointestinal disorders.
