It is not advisable to drink water during or after a meal? But what if a person drinks water just before a meal in good amount or few glasses, will it this time also hinders the pH of stomach when HCl is released by oxyntic cells? s

Dear student,

Drinking more water during meal will dilute the stomach juices and interfere with digestion, as it immediately triggers the stomach to produce more stomach acid and is a primary factor in the onset of acid reflux disease. but drinking more water just before a meal helps to consume less calories at those meal and this provides a sense of fullness, so not as much food is needed to reach the point of satiety.
