Is Milk Allergy Different Than Lactose Intolerance?

Is Milk Allergy Different Than Lactose Intolerance?

Are there differences between Milk Allergy and Lactose Intolerance? Yes. It can be confusing. Here’s information to help understand:

Milk allergy is a food allergy, which is an overreaction of the immune system to a specific food protein. When the food protein is ingested, it can trigger an allergic reaction that may include a range of symptoms from mild symptoms (rashes, hives, itching, swelling, etc.) to severe symptoms (trouble breathing, wheezing, loss of consciousness, etc.).

Unlike food allergies, food intolerances do not involve the immune system. People who are lactose intolerant are missing the enzyme lactase, which breaks down lactose, a sugar found in milk and dairy products. As a result, individuals who are lactose intolerant are unable to digest these foods, and may experience symptoms such as nausea, cramps, gas, bloating and diarrhea. While lactose intolerance can cause great discomfort, it is not life-threatening.
