In many cases, stomach acidity and heartburn may be related to the food and ingredients that the patient eats. Many foods can cause increased gas and acid production, such as sour and sweet foods, including cream cakes, chocolates, milk tea, carbonated beverages, etc. These foods can easily produce acid and gas, and if the patient often eats such foods, stomach acidity and heartburn will often occur. If the patient eats irregularly, he or she may not be able to eat on time, which may also cause stomach acid to be neutralized by food, thus causing stomach acidity and heartburn. On the one hand, the patient can go to the hospital, where the doctor can prescribe the right medication to deal with the problem, and if necessary, a gastroscopy can be performed. On the other hand, you should adjust your diet and eat less sweets and carbonated beverages when you eat, as such ingredients may aggravate the appearance of increased stomach acid and heartburn.
