Doesn’t lactase work for lactose intolerance?

Taking lactase for lactose intolerance is useful. Lactose intolerance can be helped by lactase, which helps the intestines recover gradually by secreting lactase.
Lactose intolerance is a condition in which the intestines do not secrete enough lactase and thus do not adequately break down lactose from breast milk or formula, resulting in osmotic diarrhea. Most lactose intolerance is secondary to lactose intolerance.
Lactose intolerance can be treated with the enzyme lactase, which helps the intestines to gradually restore lactase production. The treatment period is 2 to 8 weeks. The duration of treatment can be determined by the diarrhea and stool condition.
In daily life, if the lactose intolerant person does not have much diarrhea and it does not affect the normal development, no special treatment is needed, and dietary adjustments can be made.
