Under normal circumstances, milk is not flatulent. Flatulence may occur when milk is consumed improperly or when lactose intolerance and other digestive disorders are present. 1. Drinking improperly: Milk is a common beverage, rich in protein, calcium and other nutrients, and proper consumption will not cause flatulence. However, if you drink too much milk at one time, or drink it too fast or too quickly and swallow a lot of air, it will lead to an increase of gas in the stomach and intestines, which will lead to flatulence. 2. Lactose intolerance: After drinking milk, patients with lactose intolerance cannot fully digest the lactose in milk, which can also lead to bloating, diarrhea and other symptoms. 3. Other digestive disorders: chronic gastritis, gastric ulcer and other diseases may lead to increased bloating after drinking milk. It is recommended to drink milk reasonably in daily life. If symptoms of flatulence occur frequently after drinking milk, it is recommended to consult a doctor as soon as possible and intervene as soon as possible under the guidance of a medical professional.
