Babies are born with the ability to digest lactose, the sugar present in breast milk and most infant formulas. However, in some cases, they can develop intolerance, a condition in which the body produces an insufficient amount of lactase, the enzyme needed to break down lactose into simpler sugars for absorption.
Some causes of lactose intolerance are due to congenital deficiency of lactose. This means that babies produce very little or no lactase from birth. This condition is rare, but it can be hereditary.
In certain cases, intestinal injuries due to diseases such as celiac disease, gastroenteritis or other conditions can cause a temporary decrease in lactase production, resulting in lactase intolerance.
Other causes
Premature babies may have reduced lactase levels due to the immaturity of their gastrointestinal tract. This can lead to temporary lactose intolerance problems.
Furthermore, gastrointestinal infections such as gastroenteritis can temporarily damage the cells that produce lactase in the small intestine, resulting in short-term lactose intolerance.
Feeding alternatives
Before feeding your baby any type of formula, it is important to consult with a pediatrician or lactation specialist before changing the diet of a lactose intolerant baby.
These health professionals can help determine the best feeding alternative for each baby, taking into account their health and specific dietary needs. Additionally, it is highly relevant to closely monitor the baby’s response to any dietary changes and seek medical guidance if problems or complications arise.
The constant development in science and pediatrics has allowed there to be options for babies who are lactose intolerant. Some of these options are:
Alternative formulas
There are special infant formulas designed for babies with lactose intolerance. These formulas contain predigested or hydrolyzed lactose or are made from non-dairy proteins such as soy or rice.
Soy-based infant formulas
Soy-based infant formulas are an alternative for lactose intolerant babies. These formulas are made with soy proteins and do not contain lactose. However, it is important to note that some babies with lactose intolerance may also be allergic to soy, so caution should be used when introducing this type of formula.
Hydrolyzed formulas
These infant formulas contain milk proteins that have been broken down into smaller fragments. Hydrolyzed formulas may be helpful for babies who do not tolerate soy-based formulas.
Rice formulas or free amino acids
In severe cases of lactose intolerance or allergy to cow’s milk protein, formulas made from rice or free amino acids can be used. These formulas are highly hydrolyzed and contain no lactose or dairy proteins, making them safe for babies with severe food allergies.
