Lactose Intolerance in Infants & Children

Lactose Intolerance in Infants & Children

Patient Question

Hello Doctor,


Could my one-year-old be lactose intolerant if she experiences diarrhea after consuming whole milk? We switched her to whole milk two weeks ago, and a week later, she began having loose stools and diarrhea. When she was an infant, we had to switch her formula to a gentle ease variant due to the same issue. Our doctor said she shouldn't be lactose intolerant since most infants outgrow this problem, but she continues to experience it.

Possible Intolerance:

Symptoms after whole milk suggest lactose intolerance.

Discuss with the pediatrician for diagnosis and management.


Milk Protein Sensitivity:

Immune reaction to milk proteins can cause similar symptoms.

Pediatrician can differentiate and guide treatment.


Consultation Needed:

Essential to consult for accurate diagnosis and plan.

Switching to lactose-free formula may be advised.

Gradually reintroduce lactose-containing foods under supervision.
