What is a milk allergy?

A milk allergy typically occurs when a person consumes a product that contains milk, according to the Mayo Clinic.

The healthcare company said that the treatment for people who have a milk allergy is to avoid products that may contain milk.

In addition, the Mayo Clinic explains that milk allergies and milk intolerance are a little different from each other.

“A true milk allergy differs from milk protein intolerance and lactose intolerance,” the healthcare company said. “Unlike milk allergy, intolerance doesn't involve the immune system. Milk intolerance requires different treatment from true milk allergy.”

Symptoms of a milk allergy include:

• Hives
• Wheezing
• Itching or tingling feeling around the lips or mouth
• Swelling of the lips, tongue, or throat
• Coughing or shortness of breath
• Vomiting

A milk allergy can cause anaphylaxis, a severe, life-threatening reaction to an allergen that can obstruct a person’s breathing, the Mayo Clinic said.
