Full-term babies with lactose intolerance usually take lactase for two to eight weeks, and the exact time is related to the physical condition of the full-term baby and whether the baby is congenitally lactose intolerant, secondary lactose intolerant and other conditions.
1. The physique of the full-term baby: the better the physique of the full-term toddler, the lighter the symptoms of lactose intolerance, the shorter the time to take lactase, and the easier it is to recover. Therefore, parents should try to choose milk powder with comprehensive nutrition when choosing milk powder to improve the physical condition of infants and young children.
2. Congenital lactose intolerance: Congenital lactose intolerance is due to the body’s lack of lactase enzyme and leads to diarrhea. No effective treatment has been found yet, so taking lactase does not work as a cure. Infants should drink lactose-free milk powder.
3. Secondary lactose intolerance: Secondary lactose intolerance is caused by inflammation of the intestines, resulting in a temporary deficiency of the enzyme lactase. After the secondary cause of lactose intolerance is relieved, infants and young children can usually recover in 2-8 weeks.
If lactose intolerance does not improve after a period of oral lactase intolerance, full-term babies should seek medical advice and go to a regular hospital for examination and treatment, so as not to affect the growth and development of infants and young children. The above medications should be used in accordance with medical advice.
