Patient's question:
The baby next door was born not long ago, and the little one is very cute. However, his grandmother said that the little guy has been getting a lot of eczema on his butt recently, and he also doesn't eat well. Whenever he tries to nurse, he spits it out. We suggested taking him to the hospital to check it out. Later, when we went to the hospital, the doctor said it was lactose intolerance.Doctor's answer:
Hello, the reasons for lactose intolerance are: Undigested and unabsorbed lactose enters the colon, where it is fermented by bacteria present in the gut into small organic acids such as acetic acid, propionic acid, butyric acid, etc., and produces some gases such as methane. Most of these products can be reabsorbed by the colon. The main cause is the lack of lactase in the small intestinal mucosa of newborns, and some people may also develop it due to long-term avoidance of dairy products.
