Lactose intolerance is due to the lack or decreased activity of lactase in small intestinal mucosa, which can not completely digest and decompose lactose in breast milk or milk. The main symptoms are diarrhea, abdominal distension and abdominal pain that last for several weeks. Primary lactose intolerance is mainly influenced by genetic factors, while secondary lactose intolerance is usually caused by gastroenteritis. Milk is the only food from the birth of a newborn. When the baby is one year old, it is necessary to add complementary food. With the growth of age, dairy products are no longer the main food in the traditional diet, and the amount of dairy products consumed by babies will gradually decrease. In this process, infants will develop lactose intolerance, and the most obvious symptom is diarrhea, which usually occurs within 30 minutes to 2 hours after eating lactose-containing food. Intestinal spasm, abdominal distension, abdominal pain, abdominal sound and diarrhea will occur in the lower abdomen, and excessive peristalsis will also be caused by the stimulation of the intestine, and the speed of food passing through the intestine will also be accelerated. In the end, it will lead to the disorder of water and electrolyte in the body and the rapid loss of nutrients, which will lead to the decline of the baby's immunity in the long run. If your baby is allergic to lactose, you can get nutritional protection from lactose-free infant formula, which provides all important basic nutrition for your baby's growth and development. Therefore, if you are lactose intolerant, you must choose a special lactose-free infant formula, which is sold in pregnant and baby stores. You can choose.
