What's the reason for drinking pure milk

First: patients must understand that lactose is a disaccharide, its molecule is composed of glucose and galactose, the human body can not directly absorb lactose, it needs to be decomposed under the action of lactase before it can be absorbed. Due to physical differences, some people lack lactase, so when lactose is ingested, the undigested lactose will directly enter the large intestine, stimulate the peristalsis of the large intestine, and cause bellyache, diarrhea and other symptoms, which is called lactose intolerance.

Second: patients must understand that in the absence of lactase, human lactose intake can not be digested and absorbed into the blood, but retained in the intestinal tract. In the process of lactose decomposition by intestinal bacteria fermentation, a lot of gas will be produced, causing abdominal distension and farting. Excess lactose can also increase the intestinal internal osmotic pressure, prevent the absorption of water and lead to diarrhea.

Third: patients must know the lactase activity in the small intestine, the amount of lactose intake and whether they take other kinds of food at the same time. When the baby appears lactose intolerance, the most obvious symptom is diarrhea. Usually in eating lactose containing food between 30 minutes to 2 hours, there will be small bowel spasm, abdominal pain, abdominal distension, abdominal sounds and diarrhea.
