Allergy to protein over the past decade has become a real threat, and in fact earlier such a form of allergy was considered quite rare. Now the food allergy becomes more and more widespread, which means that the protein, which is a part of not only milk and meat, but also in some plant species, acquires the status of a provoking allergen. The fact is that the human body is a protein multifunctional system. Therefore, other proteins, irrespective of their source, are subject to sensitization, the body takes them and begins to recognize them. Depending on the state of the immune system, sensitization can be accelerated, active, but sometimes slow.

In fact, an allergy to protein is an allergic reaction to protein, the response of immunocompetent systems and organs to the invasion of an alien but similar in molecular composition protein.

What causes an allergy to protein?

Allergy to protein, like most other types of allergies, is provoked by an allergen that enters the gastrointestinal tract. Food intolerance of the protein is characterized by enteritis, enterocolitis, flatulence. Allergy to protein is often accompanied by dyspepsia, a disorder of the stool - diarrhea or constipation. Possible nausea, reaching for vomiting. In severe cases, the patient complains of severe pain in the epigastric region, which makes it difficult to differentiate signs of symptoms of other diseases of the digestive tract. The protein allergy is divided into types and methods of treatment, depending on the allergen: 

Intolerance to BKM - cow's milk protein

This is the most common provoking allergen, especially in children's nutrition, both newborn and older. The allergy to milk protein in babies is explained by insufficient formation of digestive organs and immature enzymatic function. Secretory systems do not have time to produce enough specific proteoenzymes, milk protein enters the body, and then into the blood, almost uncleaved. As a result, sensitization, recognition of the protein structure and, as a consequence, an allergic reaction begin. Therapy of allergy to milk protein, first of all, consists in excluding from the ration of all whole-milk products. Sorbents are also prescribed to remove toxins from the body. Effective Enterosgel, which protects the mucous membranes of the digestive tract from contacting the CEC - immunocirculatory complexes. Symptomatic (antihistamine) therapy is prescribed only by a doctor, self-medication is unacceptable, as in any other cases of allergy.

Allergy to protein of milk origin

An allergy to a protein of milk origin is rare in adults. Usually, by the age of seven, which began in early childhood, such an allergy goes away. The cross-form that connects allergy to BKM and protein of meat or fish is also rare, treated with the exception of provoking foods from the patient's diet.

Allergy to fish protein, meat

An allergy to fish protein, meat is most common among adults, children due to the specifics of the diet suffer this form less often. Typical for this type of allergy can occur during adolescence, in the period of puberty. Rarely does an allergy to meat protein, mainly - it's a beef protein. The most aggressive is the protein of sea fish, shrimp and other seafood. This paralvalbumin sarcoplasm is a protein that remains unchanged even with prolonged heat treatment. In shrimps, crustaceans contain tropomyosin, which is able to persist even in the aquatic environment surrounding marine life and is practically not subject to digestion juice treatment. This type of allergy does not depend on the age of the patient, the provoking allergen is not amenable to treatment, so a person who has been diagnosed with an allergy to fish protein should always forget about these products. Treatment is standard: elimination of allergenic food, sorbing drugs, antihistamine therapy.

Allergy to egg white

Allergy to protein is possible with respect to eggs and products containing them. The most dangerous are ovomucoid, ovalbumin, conalbumin. These mucoproteins are aggressive, long in the digestive tract, masking under the guise of a molecular-like trypsin (natural enzyme).

Allergy to nuts

Allergen can be nuts of all kinds. Peanuts are considered dangerous, less threatening in sense of provocation of an allergy - almonds, further in the list hazelnut and a walnut are registered. The reaction can be rapid and occur at any age. The ability to sensitize is preserved forever, so nuts in case of allergic manifestations should be excluded from the diet. Also, be careful with the use of foods containing nuts, even in a minimal amount.

An allergy to protein can be triggered by the use of both cereals, legumes, and soy products. Organic proteins, specific proteins also pose a danger to people prone to allergic reactions.

How does the protein allergy manifest itself?

The protein allergy is clinically manifested identical to any other form of allergy. As a rule, allergic reactions to protein appear dermally, that is, on the skin. It can be itching, rashes, often swelling. Hyperemia manifests itself in different ways, locally, locally, but can be generalized. If the protein allergy affects children, then dermatitis is typical for this form, they are localized in the folds of the skin, often characterized by dryness, scaling. Fatigue, which, as a rule, the babies happen in the first year of life, can not be neutralized by conventional means. Also, protein allergy in newborns can manifest in the form of a persistently not passing gneiss - milk crust. In adults, skin manifestations of food protein intolerance become allergic reactions of the mucous membranes. It is an allergic rhinitis, often with an asthmatic component. In the pathological process, the mucous eyes are gradually involved - conjunctivitis, tear appears, sclera is hyperemic. A typical sign - sand in the eyes, itching and redness, are often considered symptoms of allergies of other forms, contact. Therefore, it is very important to collect a complete history, including dietary, to pinpoint the source that provokes allergies.
