Whether or not yogurt is good for your stomach depends on the individual and cannot be generalized. Yogurt has some benefits for normal people or people with indigestion symptoms, but not for peptic ulcer patients. Yogurt contains certain probiotics such as Lactobacillus and Streptococcus thermophilus. Probiotics can increase the acidity in the intestines, thus inhibiting the growth and reproduction of spoilage bacteria and reducing intestinal gas production, which can reduce symptoms such as flatulence, indigestion and diarrhea. However, because yogurt has a certain amount of acidic products, gastric ulcers, duodenal ulcers and other patients eating, it is possible to stimulate the ulcer wounds, resulting in aggravation of the condition. Therefore, peptic ulcer disease people are not recommended to eat more yogurt. Patients with stomach discomfort should actively seek medical attention and standardize treatment under the guidance of a doctor.
