The reason for stomach pain is usually acute gastritis, chronic gastritis and gastric ulcer, etc. If stomach pain occurs, it means that the gastric mucosa is edematous or the gastric mucosa is ulcerated. If you drink yogurt, on the one hand, yogurt is a fermented food and contains some acidic substances, which can easily aggravate the symptoms of inflammation or ulceration of the gastric mucosa, on the other hand, yogurt is a high protein food, if the gastric mucosa is in the period of edema and inflammation, consuming high protein food can easily increase the digestive burden of the stomach, causing indigestion and aggravating the symptoms of gastritis. If you drink yogurt when you have stomach pain, there will be a large amount of stomach acid secretion in your stomach under the stimulation of yogurt, which will aggravate the stomach pain instead. When you have stomach pain, you need to eat light, easily digestible, liquid or semi-liquid food with more vitamins, and avoid spicy and stimulating, cold, greasy, high sugar and high protein food.
