Yogurt is a drink made from milk, sterilized and fermented with lactic acid bacteria. It is easier to digest and absorb than milk, and can supplement the body with high quality protein, calcium and probiotics, which helps to laxative, stomachic and antibiotic. Whether or not you can drink yogurt on an empty stomach varies from person to person. Healthy people can drink yogurt on an empty stomach, but those with weak stomachs are not recommended to drink yogurt on an empty stomach. Pepsin needs to function in an acidic environment, and the concentration of stomach acid is usually higher than yogurt. When yogurt enters the stomach, it has little effect on the acidic environment in the stomach, so yogurt usually does not affect the normal digestive function of the body, so healthy people can drink yogurt on an empty stomach. In addition, the body will secrete a lot of stomach acid after eating, making the acidity in the stomach higher than that of fasting. Therefore, it is recommended to drink a cup of warm water before drinking yogurt on an empty stomach to help reduce the acidity in the stomach and promote the survival of probiotics. People with weak gastrointestinal function are not recommended to drink yogurt on an empty stomach, otherwise it will easily cause gastrointestinal discomfort. For example, patients with gastritis and gastric ulcer, drinking yogurt on an empty stomach can easily stimulate the gastric mucosa and cause discomfort. It is also not recommended for diabetic groups to drink yogurt with added sucrose, as it may cause blood sugar to rise. In addition, it is recommended that you drink yogurt 1-2 hours after meals, which helps absorb the nutrients in yogurt and reduce the stimulation of yogurt on the stomach.
