How to check baby lactose intolerance

Lactose intolerance can be identified by lactose tolerance test, hydrogen breath test, stool acid test, etc. 1. Lactose tolerance test allows the baby to take a certain amount of lactose orally, and then detects changes in blood sugar levels at different time periods. If the blood sugar does not increase significantly or does not increase, it may indicate lactose intolerance. This is a relatively direct detection method, but the operation is relatively complicated. 2. Hydrogen breath test After your baby ingests lactose, check the hydrogen content in the exhaled gas. Lactose is not fully digested by intestinal bacteria, it will be decomposed by intestinal bacteria to produce hydrogen, and the hydrogen content in the exhaled gas will indicate lactose intolerance. This method is simple and easy, and it is not invasive to the baby. 3. Fecal acid test detects the pH of the baby's stool. When lactose intolerance occurs, undigested lactose is fermented in the intestine, which makes the stool acidic. In this way, it is possible to initially determine whether lactose intolerance exists. During the examination, it is necessary to pay attention to the appropriate method and combine the specific symptoms and signs of the baby for comprehensive judgment. At the same time, once lactose intolerance is diagnosed, appropriate adjustments need to be made in feeding, such as choosing lactose-free or low-lactose formula, to alleviate the baby's discomfort. The doctor will give specific guidance and advice according to the baby's situation.
