A dairy protein allergy is a common food allergy that is primarily found in young children, but can develop at any age. The proteins in the dairy cause the body to react as if it was under attack. The Cleveland Clinic states that a milk allergy is not the same thing as lactose intolerance. Lactose intolerance is caused by an inability to digest a sugar found in milk and is not affected by milk proteins. If you suspect that you or your child is allergic to milk, call your doctor. A severe dairy protein allergy can cause anaphylactic shock, a life-threatening allergic reaction.
Symptoms
If you're allergic to dairy proteins, you will develop symptoms within a few minutes or up to an hour after you ingest the product. The most common symptoms of a dairy protein allergy include asthma, sinus irritation, skin rashes and digestive complications, according to TeensHealth. If you develop asthma, you may be short of breath, find it difficult to breathe and develop wheezing. Sinus irritation can cause congestion, stuffiness, a runny nose and postnasal drip. Skin rashes that are commonly related to a milk allergy include hives and eczema. Digestive complications may include vomiting, diarrhea and nausea.
The Cause
A dairy protein allergy is caused by a malfunction of the immune system. Your immune system protects your body from harmful substances, such as bacteria, toxins and viruses. During a milk protein allergy, your immune system mistakes the proteins, whey and casein, as a dangerous substance and reacts as if it were fighting off a dangerous substance. Part of this reaction occurs because of the creation of immunoglobulin E, or IgE antibodies that attempt to fight off the dairy proteins, notes MayoClinic.com. This causes a chemical chain-reaction that leads to inflammation and swelling throughout your body.
Avoidance
TeensHealth states that avoiding the consumption of all dairy products is the most effective way to prevent and treat a milk allergy. Dairy proteins are commonly found in cheese, yogurt, ice cream, custard, pudding and chocolate. These proteins may also be used in unsuspected products, such as hard candies, non-dairy creamers and baked goods.
Consideration
Dairy products are a primary source of vitamin D and calcium. You may need to increase your intake of foods that are high in these nutrients, such as broccoli, spinach and soy products, according to the Cleveland Clinic.
