A member asked:

Would gastritis cause malabsorption of vitamins, such as d, b12?

A doctor has provided 1 answer

Gastritis: Certain forms of gastritis destroy cells that secrete intrinsic factor which is essential for absorption of vitamin B12. This can also alter th pH in the GI tract and influence other functions. Vit D is a fat soluble vitamin that is not dependent on the stomach for absorption.
