Can cow's milk protein allergy lead to other allergies?

What is cow's milk protein allergy?

Cow's milk protein allergy (AMK) is one of the most common food allergies in infants and young children. It involves hypersensitivity of the body to cow's milk proteins, which cause an allergic reaction. Symptoms can range from mild to very severe and even potentially life-threatening.

Typical symptoms of cow's milk protein allergy include rash, hives, abdominal cramps, vomiting, diarrhea and even anaphylactic shock. If you experience such symptoms after consuming products containing cow's milk protein, consult your doctor as soon as possible.

Can it lead to other allergies?

Research suggests that people with cow's milk protein allergy may be at greater risk of developing other allergies. There is some association between AMK and allergies to gluten, peanuts, soy and eggs. This means that children who are allergic to cow's milk protein may also be more susceptible to food allergies later in life.

Mechanism of development of other allergies

The exact mechanism responsible for the link between cow's milk protein allergy and other allergies is not yet fully understood. However, there are several theories that can explain this phenomenon. The first is the leaky gut theory.

According to this theory, in the case of an allergy to cow's milk protein, the intestinal mucosa can become damaged. This in turn leads to increased intestinal permeability, allowing cow's milk proteins and other allergens to enter the bloodstream. The body's immune system reacts to these allergens, leading to the development of further food allergies.

Another theory suggests a common cross-reaction. According to it, certain protein structures present in both cow's milk and other allergens can trigger allergic reactions in sensitive individuals. This means that if the body already has a specific reaction to cow's milk protein, another structurally similar protein may also trigger an allergy.

What are the allergy management options?

Unfortunately, treatment of cow's milk protein allergy mainly involves eliminating cow's milk protein from the diet. Dairy products and other products containing cow's milk protein must be excluded from a child's diet. However, there are alternative sources of protein, such as soy milk, almond milk or rice milk, which can be used as substitutes.

If you have a cow's milk protein allergy, you should also avoid products in which cow's milk protein may be hidden, such as certain types of processed meats, pastries and sauces. It is important to read labels carefully and avoid potential sources of allergens.

Summary

Cow's milk protein allergy can lead to other allergies, such as allergy to gluten, peanuts, soy or eggs. Although the exact mechanism of this phenomenon is not fully understood, there are several theories that suggest how cow's milk protein allergy can affect the development of other allergies. Treatment mainly involves eliminating cow's milk protein from the diet, which requires diligence and a conscious choice of foods.

In the case of any food allergy, it is always a good idea to consult a doctor to get the right diagnosis and guidance on allergy management. Awareness and proper support can help maintain health and quality of life for cow's milk protein allergy and other food allergies.
