Should I talk to a doctor about congenital lactose intolerance symptoms?

If you or your child have symptoms such as diarrhea and cramps after consuming dairy products, it's probably best to see a doctor to determine whether it's congenital lactose intolerance. This is especially true if you have a young baby who has persistent diarrhea and is being fed breast milk or a formula that contains lactose. Your doctor will be able to determine the cause of the symptoms and can recommend the best treatment for you or your child.
