Red wine is not recommended for people with a weak stomach. Red wine contains alcohol, most of which is absorbed in the stomach, so it is not recommended for people with a weak stomach. In addition to red wine, any drink containing alcohol is not recommended for people with a weak stomach. Alcohol is quickly absorbed into the bloodstream after entering the stomach, and then spreads with the bloodstream to all the organs of the human body, and the secretion of gastric juice will also increase. At the same time, ethanol can directly damage the barrier function of the gastric mucosa, promote gastric acid and pepsin secretion increase, leading to vascular endothelial damage, inhibit the healing of ulcers, but also can cause acute erosive hemorrhagic gastritis. Therefore, for the sake of physical health, people with bad stomachs had better choose not to drink red wine.
