Is there lactose intolerance in neonates?

Yes, lactose intolerance in neonates can occur. Lactose intolerance is a condition where the body is unable to fully digest lactose, the main sugar found in milk and other dairy products.

In neonates, the most common cause of lactose intolerance is a deficiency of the enzyme lactase, which is responsible for breaking down lactose into smaller sugars that the body can absorb. This deficiency can be caused by various factors, including genetics, certain medical conditions, and even premature birth.

Symptoms of lactose intolerance in neonates can include:

- Diarrhea

- Abdominal bloating and gas

- Excessive crying and fussiness

- Poor weight gain

- Acid reflux

If lactose intolerance is suspected in a neonate, a healthcare provider may recommend reducing or eliminating the consumption of milk and other dairy products to see if symptoms improve. In cases of severe lactose intolerance, specialized formula may be recommended.

It's important to note that lactose intolerance in neonates is different from cow's milk protein allergy, which is a reaction to the proteins found in cow's milk.
