Drinking milk will make you sick for the following reasons:
1. The patient is lactose intolerant. These patients lack enzymes that can decompose lactose in milk, which will lead to lactose not being decomposed into glucose and galactose in the small intestine. These lactose do not decompose and digest in the small intestine, but enter the large intestine, where they are fermented by bacteria to produce organic acids and gases, causing abdominal distension, nausea and vomiting.
2. Some patients will drink milk for a short time, which may easily lead to cholecystitis and nausea and vomiting.
3. If the patient eats too much milk at a time and suffers from gallstones, it is easy to induce biliary pancreatitis, and nausea and vomiting will also occur after drinking milk. 4. Some women of childbearing age are pregnant. After drinking milk, they are prone to nausea and vomiting due to hormonal changes in the body, which is a pregnancy reaction, so don't care too much.
