Milk cannot be used to treat stomach acid. Theoretically, the proteins in milk can be used to neutralize stomach acid, but milk is rich in calcium and other substances, which will increase the secretion of stomach acid when it is digested and absorbed into the stomach, and this secretion exceeds the neutralizing effect of the proteins in milk, so drinking milk may aggravate the secretion of stomach acid when you have too much acid in your stomach. Therefore, milk cannot be used to treat hyperacidity. For patients with hyperacidity, overweight, smoking, drinking, overeating, eating chocolate and acidic food can increase the secretion of gastric acid, so it is recommended that patients try to regulate their lifestyle and diet to avoid the above risk factors. When you have excessive stomach acid, you should consult a medical doctor in time to clarify the cause of the disease and carry out targeted treatment with the help of a professional physician, and consult a professional physician for the specific dietary structure as well.
