what can cause loss of stomach lining
Acute gastritis is usually caused by an irritant or infection, and can result in an acute upset stomach, but usually settles quickly with simple treatments when the cause is removed. Chronic gastritis is a condition in which the stomach lining is damaged long-term, often due to infection by H. pylori. Chronic gastritis does not usually cause indigestion or pain, but severe damage may result in anemia due to vitamin B12 deficiency.
