Abdominal pain after drinking milk is related to the milk itself, but also to milk irritation of the gastrointestinal tract, such as drinking spoiled or expired milk, as well as milk that is cold can lead to abdominal pain. In addition, abdominal pain from milk consumption may also be an allergic reaction of the gastrointestinal tract, which is a kind of intestinal stress reaction. In life, it is recommended to pay attention to the shelf life of milk and also to avoid drinking overnight milk products. It is also important to avoid consuming too much acidic food after drinking milk to avoid causing reactions in the intestinal tract, resulting in abdominal pain or diarrhea. From the point of view of Chinese medicine, if the body is cold, drinking cold dairy products or food is also likely to cause abdominal pain, so it is recommended to drink hot milk. It is important to develop good eating and living habits to prevent abdominal pain from occurring.
