Is Your Stomach Acid (Gastric Acid) Diluted When You Drink Water?
Short answer: Yes, drinking a lot of water will certainly change the pH of the stomach, but this amount is trivial. However, since your stomach is very acidic, to begin with, drinking water will not dilute it significantly. Also, there...
