How is the allergy manifested? This question arises not only for those who notice the signs of this common disease, but before the doctors, because the allergy in recent decades has acquired many new forms and clinical manifestations. Standard clinical symptoms are local and general manifestations.
Local symptoms can be:
- Edema in the nasopharynx, mucous discharge from the nose, rhinitis;
- Lachrymation, redness of the eyes, conjunctivitis;
- Spasm of bronchi, shortness of breath, whistles, noises in breathing;
- Otitis, hearing impairment;
- Cough, dry, manifested mainly during sleep, at night;
- Hives, dermatitis, itching and redness of the skin.
Common symptoms often combine with local ones and can be as follows: swelling of the nasopharynx with shortness of breath and pruritus, bronchospasm with reddening of the eyes, general swelling of the body, often leading to anaphylactic shock. Symptoms of allergies are often polymorphic, organs, tissues, and systems are involved in the disease. However, most often allergies suffer from respiratory system, skin and gastrointestinal tract.
The rate of development of symptoms of an allergic reaction is divided into delayed and immediate types. Itching, hyperemia, urticaria can be an immediate allergic reaction, but the same diseases are also the companions of serum sickness, which is considered a delayed reaction allergy.
How is the allergy manifested? What forms does it have and how are allergic diseases called? Clinically, the allergy is divided into:
- Pollinosis (hay fever);
- Allergic rhinitis;
- Toxicodermia of allergic etiology;
- Conjunctivitis of allergic etiology;
- Hives;
- Serum sickness, hemolytic crisis;
- Edema Quincke;
- Thrombocytopenia;
- Dermatoses;
- Enteritis of allergic etiology;
- Anaphylactic shock;
- Bronchial asthma.
Each of the allergens can trigger a whole chain of signs of an allergic disease. Birch pollen can provoke not only habitual rhinitis, but also lead to spasm of the bronchi, and then to hives. The polymorphism of the allergy is extremely dangerous and that even an allergic reaction, habitual for years, can sometimes end with anaphylactic shock. People suffering from allergies, and in recent decades their number is growing rapidly, can react simultaneously to food allergens, pollen and epidermal irritants (skin allergy).
[How is the allergy manifested? Symptoms of allergic dermatosis
Dermatoses of allergic etiology arise from contact with medicinal, chemical, cosmetic agents. The reaction can be provoked by latex, metal and many other substances that a person faces daily. Even food that allergies do not eat as food can cause swelling and itching. Also, allergic dermatoses are provoked by bites of various insects, from mosquitoes to wasps, dermatosis can also be a consequence of emotional stress. Symptoms of allergic dermatosis are very obvious, among them the following are typical:
- Itching itch;
- Rashes, hives;
- Skin peeling;
- Eczema;
- Neurodermatitis.
Summarizing the symptoms, it can be divided conditionally even anatomically and obtain the following list:
- Allergies - nose (rhinitis, sinusitis, swelling of the nasopharynx);
- Allergies - eyes (allergic conjunctivitis);
- Allergy - VDP (upper respiratory tract - shortness of breath, bronchospasm, asthma);
- Allergies - ears (hearing loss, otitis allergic etiology);
- Allergy - skin (allergic dermatitis, urticaria);
- Gastrointestinal Allergy - allergenitis. .
How is the allergy manifested? The question for which today in the medical world there are answers, since allergy symptoms are well understood. It remains only to find out the real causes that cause allergy, which is considered a disease of the new century. The etiology of this insidious disease is still not clear, which is why no effective remedy has been found that can stop the allergy epidemic, which is engulfing an increasing number of people.
