From the Guidelines
You can switch back to regular formula from low lactose formula when your baby's symptoms of lactose intolerance have resolved, and it is safe to introduce lactose-containing formulas under supervision to assure that carbohydrate malabsorption does not complicate the clinical course. When transitioning back to regular formula, it is crucial to monitor your baby's digestive health and look for signs that their digestive system has recovered, such as normal stools, no gas or bloating, reduced fussiness, and good weight gain. According to the Centers for Disease Control and Prevention 1, patients with true lactose intolerance will have exacerbation of diarrhea when a lactose-containing formula is introduced, and the presence of low pH or reducing substances in the stool in the absence of clinical symptoms is not diagnostic of lactose intolerance. Some key points to consider when switching back to regular formula include:
- Gradually introducing regular formula by mixing increasing amounts with the low lactose formula over several days to prevent digestive upset
- Monitoring your baby's symptoms and adjusting the transition as needed
- Being aware that some babies may need to remain on lactose-reduced formula for longer periods, while others may outgrow their temporary lactose intolerance quickly. It is essential to prioritize your baby's digestive health and adjust the transition to regular formula accordingly, as many cases of lactose intolerance in infants are temporary and the digestive system can recover its ability to produce lactase, the enzyme that breaks down lactose 1.
From the Research
Switching Back to Regular Formula
- The decision to switch back to regular formula after using low lactose formula depends on the individual's lactose intolerance symptoms and their ability to digest lactose 2, 3.
- There is no specific timeline for switching back to regular formula, as it varies from person to person and depends on the severity of their lactose intolerance 4, 5.
- It is essential to monitor the individual's symptoms and adjust their diet accordingly, ensuring they receive adequate nutrition and do not experience adverse reactions to lactose 6.
Considerations for Switching Back to Regular Formula
- Before switching back to regular formula, it is crucial to assess the individual's lactase activity and their ability to digest lactose 2, 4.
- A gradual introduction of regular formula may be necessary to prevent adverse reactions and allow the individual's digestive system to adjust 3, 5.
- It is also important to consider the nutritional content of the formula and ensure that it meets the individual's dietary needs 6.
Nutritional Management of Lactose Intolerance
- The nutritional management of lactose intolerance should prioritize a balanced diet that provides adequate nutrients, including calcium, protein, and vitamins 2, 5.
- Lactose-free or low-lactose products can be used as alternatives to regular dairy products, but it is essential to choose products with similar nutritional content 4, 6.
- Probiotics and exogenous enzymes may also be used to aid in lactose digestion and reduce symptoms of lactose intolerance 3, 5.
