Should I talk to my doctor about my secondary lactose intolerance symptoms?

If you have symptoms such as diarrhea and cramps after you eat dairy products, it's probably best to see a doctor to determine whether it's secondary lactose intolerance. If you're aware of an underlying medical condition that may cause secondary lactose intolerance, alert your doctor. If not, your doctor may have to perform tests to determine what, if any, underlying disease may be causing your symptoms. It's especially important to see a doctor if you have severe symptoms that are starting to interfere with your daily life.
