What is the reason for drinking milk and flatulence?

What is the reason for drinking milk flatulence? The most common reason for drinking milk flatulence is lactose intolerance, because milk generally contains more lactose, and lactose content in ordinary dairy products is relatively low, but in higher concentrations of milk, lactose content can reach 6%-8%. Lactose is a sugar present in the mammary gland of mammals, and naturally only exists in dairy products. Lactose has many advantages, especially for probiotic reproduction. However, for some patients with special constitutions, lactose intolerance will appear after drinking milk. Therefore, it will show more abdominal gas and more abdominal fluid, so it will show abdominal pain and diarrhea, which is called lactose intolerance in medicine. If lactose intolerance is shown, milk can be changed to yogurt products, which can also alleviate the above symptoms.
