Will the medicine that blocks stomach acid hinder me from properly digesting food?

Yes. Too little acid in the stomach can feel like too much acid in the intestinal tract. If there is not enough acid passing into the GI tract to trigger the release of bicarbonate, (sodium bicarbonate) there will be too much acid and it will burn or become inflamed.
Yes. We need a certain amount of acid for proper digestion. If the acid is reduced a little when there is too much, digestion should not be affected. However, if acid is reduced too much, food cannot be properly digested. In addition, if there is too little acid. Bacteria that finds its way into our intestinal tract will not be killed. It is important to find the cause of too much acid.
