Patients with stomach ulcers can drink yogurt. Gastric ulcers are caused by auto-digestion of stomach acid, no acid, no ulcers, and Helicobacter pylori infection also plays an important role in the development of ulcers. Normally, the pH of the gastric juice is roughly between 1.5 and 4. Just eating, no matter what kind of food you eat, can cause the secretion of stomach acid. Yogurt, although acidic, produces very little stomach acid compared to its own secretion, so it can be eaten. However, for the active stage of ulcers or during the period of taking medication for treatment, it is still recommended to eat as little acidic food as possible. Therefore, patients with gastric ulcers should pay attention to their diets, alcohol must not be drunk, and acidic food should be eaten as little as possible. There are also some such as non-steroidal drugs, aspirin and so on, antipyretics are not recommended.
