Food allery characte loves the diversity of symptoms. Food allergies can occur with other diseases. This is the reason for the difficulties in its diagnosis. Dermatological symptoms allow for very rapid detection of allergy and the diagnostic challenge is to identify the sensitizing allergen.
In contrast to food allergies give a picture of the disease similar to chronic inflammation of the gastrointestinal tract. In addition to type I hypersensitivity reaction, it seems that it is accompanied by delayed-type hypersensitivity or allergic chronic inflammation of the gastrointestinal tract.
Generally obajwy food allergy can be:
1. reactions
* Hives (angioedema);
* Atopic dermatitis,
* Grudzik allergic, other changes associated with itching, dry skin
2. reactions of the respiratory system
* Persistent runny or stuffy nose constantly,
* Recurrent infections of the upper and lower respiratory tract
* Inflammation of the ear,
* Swelling of the larynx,
* Asthma,
3. gastrointestinal symptoms
* Abdominal colic
* Vomiting and diarrhea
* Lack of appetite
* Abnormal stool (diarrhea, constipation)
* Abdominal pain, nausea
* Abnormal weight gain,
4. neurological reactions
* Continuous irritability, hyperactivity,
* Sleep disturbances
* Migraine headaches,
5. systemic reactions
* Anaphylactic shock (life threatening).
Symptoms of food allergy in children
Every second child with this kind of allergy downpour, vomit, suffer from colic, abdominal pain, diarrhea is, loose stools with blood or the opposite - constipation. It also happens that they felt a strong aversion to eating the food.
Rash is the most common symptom of milk allergy. Baby has a rough, red cheeks and dry skin. In older children there are amendments on the petals of the ears, creases of the elbows and knees, sporadically throughout the body. Skin lesions are accompanied by great itching.
In infants, a common symptom is sapka, or obstruction of the nose without discharge, in older children - a persistent runny nose, itchy nose, hoarseness, throat clearing, chronic cough, laryngeal edema, otitis media, and sometimes shortness of breath.
Shock (Note, you need instant contact with the doctor!). Very rare violent reaction to a product containing a substance consumed, in which the child is allergic. Symptoms are systemic, and always dangerous: paleness, vomiting, rapid heartbeat, shortness of breath, diarrhea.
Quite exceptional symptom of allergies may also be: nocturnal enuresis, dark circles under the eyes, joint pain, swelling, muscle pain, sweating, fatigue, irritability, impaired concentration, headaches, increased body temperature.
It is regarded as the first signal of potential clinical atopic disease, may become manifest at any age, but because of the specific state of morphological and biochemical gastrointestinal immune infants and young children is usually ascertained at this stage of life.
The development of food allergy is beyond the genetic factors is also required systemic exposure to food allergens (trofoalergeny). Among the risk factors listed in addition to the early introduction of dietary mixtures of cow's milk and solid products (ie weezning time). Of course, time is very important natural feeding. However, its protective role to prevent the development of food hypersensitivity in children is still under discussion, the fact the presence of these allergens in the milk of mothers who consumed a nutritional products.
Symptoms of food allergy may be jednonarządowe or involve several organs (systems) simultaneously. For this reason, we can distinguish several forms of clinical allergy based on symptoms ascertained in allergy to cow milk:
* Gastro-intestinal
* Cutaneous
* With respiratory and / or ears,
* From chronic malnutrition,
* Shock,
* And other less common symptoms, such as for example, anemia, significant shortages of body weight, hyperactivity.
In older children, over 3 year of age. To help diagnose allergic process may be the statement:
* Szaroziemisty or pale color skins,
* Child's facial expression in favor of the constant fatigue, swollen and bluish-colored around the orbits (the dark circles under the eyes)
* Feelings or symptoms of blocked nose, allergic salute (hand wiping your nose because of the continuous leakage of mucus), the presence of transverse wrinkles on the nose,
* Clad (pobrużdżony, geographic) language
* Long eyelashes
* Various involuntary habits (tics, grimaces, nose picking, rubbing the nose, throat clearing, interspersed - fukanie, snoring, nail biting), poor nutrition, or the degree of weight deficiency.
If the application of nutritional therapy does not cause allergic reactions mute-immune or the patient represents a severe clinical form, we can assist our investigation drugs.
Frequently we use three groups of drugs:
* Antihistamines: first-generation (eg Clemastin, Diphergan, Phenazolina) and second generation (cetryzyna, loratydyna);
* Preparation of combined antihistaminic and antiallergic - Ketotifen;
* Medicines used topically przeciwalergicznymi, preventing release of mediators of type I allergic reaction - cromolyn sodium, which deserves special attention because it can be administered orally, szczegónie in gastrointestinal allergy (Nalcrom, Polish Cropoz formulation G).
With age, the share is reduced pathogenic food allergens. Thus, during the period of clinical improvement after a certain period of an elimination diet should be attempting to extend its previously eliminated foods.
