Milk allergy is one of the “big eight” food allergies. “Big eight” foods account for about 90 percent of food allergy reactions. In addition to milk, they include, eggs, peanuts, tree nuts, soy, wheat, fish, and shellfish.
Milk allergies are particularly prominent in children and can cause a litany of symptoms including gastrointestinal discomfort. Many adults develop an aversion to milk later in life. While it may be a bona fide milk allergy, it could also be lactose intolerance.
What’s the Difference
Milk allergy is an immune reaction to protein found in cow’s milk and other dairy products. Even though these proteins are harmless, the immune system misjudges them as dangerous invaders such as germs or bacteria. The immune system attacks with an allergic reaction, unleashing chemicals like histamine into the body than can lead to stomach problems, hives, hay fever and other allergy symptoms.
On the other hand, lactose intolerance is a digestive issue stemming from low levels of the enzyme lactase. Lactase is the enzyme produced in the small intestine that processes the sugar (lactose) in milk. Without lactase, you’ll often feel crampy and gassy shortly after eating or drinking milk products. You may also develop diarrhea. Lactose intolerance varies. Some people can digest small amounts of milk products without repercussions. Others can’t stomach any foods that contain lactose.
For lactose intolerance, some people may find relief through taking supplements such as enzymes. However, most people are simply limited to controlling the amount of lactose-based products that they eat. Fortunately, there are quite a few lactose-free food alternatives to help people steer clear of trigger foods while still eating a reasonably normal diet.
For those with milk allergies, a treatment known s sublingual immunotherapy (SLIT) offers allergy sufferers another option besides avoiding ubiquitous milk products. SLIT works like allergy shots, desensitizing the body to allergens in the environment so that it can tolerate them without reactions. In the case of SLIT for milk, the body learns to tolerate milk proteins, but instead of relying on allergy shots to deliver antigen to the body, SLIT uses under-the-tongue allergy drops for allergy treatment.
