Drinking small amounts of water with meals is fine and does not harm the stomach, but drinking large amounts of water with meals may aggravate the burden on the gastrointestinal tract and is not conducive to digestion.
Under normal circumstances, stomach acid has a certain digestive function for food, in addition, it can also help to kill the bacteria that have not been eliminated during the processing of food. If you drink a lot of water during meals may lead to dilution of stomach acid, which is not conducive to the digestion of food, and at the same time is not conducive to killing bacteria in food, which can easily cause stomach damage.
In addition, drinking a lot of water during meals may also make the stomach over-dilated in a short period of time, affecting the contraction of the stomach as well as the speed of food transfer to the intestines, thus increasing the burden on the stomach and affecting the peristaltic movement of the stomach, which in the long run may cause gastritis, peptic ulcer and other diseases.
