Allergy Symptoms
Symptoms of allergies are purely individual and extremely diverse. All manifestations observed during an allergic reaction directly depend on which systems and organs of the human body were exposed to the penetrated allergen. As many years of observations have shown, the skin, the gastrointestinal tract and the respiratory tract are most often involved in the allergic process.
allergy symptoms in children are subdivided into slow reaction( duration of manifestations ranging from hours to days) and immediate type reaction( after exposure to the allergen manifestations occur read from seconds to several hours).However, this division is to some extent arbitrary, since it is assumed that the development of allergic reactions is always occurs immediately after an event of contact with the provoking allergen and lack at first external manifestations associated with much more massive impact on systems and organs of the body, and therefore moreProlonged formation of the immune response.hay fever( pollinosis), allergic dermatitis, urticaria, bronchial asthma, allergic conjunctivitis, anaphylactic shock, allergic rhinitis, angioedema, serum sickness:
allergic processes K immediate type allergic reactions include the following various severity and clinical symptoms. Perhaps the most dangerous allergic reactions of the immediate type are anaphylactic shock and Quincke's edema, which often develop after the bite of bees and other poisonous insects. For example, angioedema may affect the back of the spine, neck, face and cause suffocation in a patient that without the provision of timely emergency care is usually fatal. Therefore, all without exception, allergic reactions of immediate type should be eliminated as soon as possible, using qualified medical care.
Most often a physician is faced with a whole complex of clinical manifestations and symptoms caused by an allergen. Among the delayed allergic reactions, I want to dwell on cytotoxic reactions, which, due to the involvement in the pathological process of beginners rapidly deteriorating blood cells, are marked by increased danger to human life. Due to loss of blood cells may develop diseases such as hemolytic anemia and leukoplakia, however the greatest danger is thrombocytopenia, causing multiple internal and external bleeding. Diagnosis of cytotoxic reactions is especially difficult, becauseThe patient usually does not associate with unexpectedly any hemorrhages of the eye vessels with any medicinal or food allergen, and also numerous bruises appearing on the body.
The cause of a number of different symptoms of allergies in children can be absolutely any allergen. For example, in a patient with a child's pollinosis, the allergen of birch pollen can cause not only rhinoconjunctivitis, but also hives with bronchospasm. Allergic rhinitis or pollinosis caused by allergens that are present in the ambient air. It can be dust, wool or feathers of animals, pollen. Symptoms of hay fever allergy: sore throat, sneezing, watery eyes, runny nose, itching in the nasopharynx.
Cutaneous allergy symptoms .Most often, skin symptoms develop after eating an allergen with food. Usually this applies to seafood, milk, eggs and citrus. Also often the cause of skin symptoms may be medicines and pollen of plants. Typically, cutaneous allergic manifestations develop over forty eight hours after contact with the provoking allergen and are accompanied by symptoms such as rash, itching, redness, filled blisters, swelling liquid. In people with contact dermatitis, skin allergy symptoms begin to appear only a few days after contacting the allergen and exclusively at the point of contact. Some allergens, if they get on healthy skin in small quantities, can manifest themselves only after a week from the moment of contact. As instilled, to a new contact allergen the body develops a sensitivity of at least ten days.
Symptoms of acute allergic contact dermatitis: the appearance of itching vesicles and papules, the development of lichen-like blood platelets. There were recorded cases of allergic contact dermatitis with all skin areas - erythroderma, exfoliative dermatitis.
Also for skin allergy symptoms include atopic dermatitis and hives. Urticaria manifests a fickle rash in the form of flattened or convex reddish itchy irregularly shaped formations. More often, urticaria develops due to contact with allergens, which are contained in medicines, food and air.
There is also a whole group of allergic skin diseases, under the general name - allergic dermatoses. These diseases may develop as a result of penetration into the body by injection administration, transmucosal gastrointestinal tract, or directly in contact with the skin cosmetic and / or medical products, food products, metals, latex, aeroallergens, household chemicals and so forth. Often, allergic skin reactions developIn response to emotional disorders and insect bites. Symptoms of allergic dermatoses: skin rash on the type of hives, redness, and itching of the skin, changes in the pattern and dry skin.
Perhaps the most dangerous form of an allergic reaction is anaphylactic shock. Symptoms of anaphylactic shock: the appearance of a rash all over the body, seizures and sudden occurrence of shortness of breath, loss of awareness, involuntary defecation and urination. The symptom of an allergy - anaphylactic shock, develops no later than five hours after the ingress of the allergen into the body. In the case of the slightest suspicion of the development of this condition should promptly call for emergency care.
Symptoms of allergy by airways are caused not only aeroallergens, but also infections( Candida, neisserial, chlamydia, pneumocystis, mycoplasmosis, SARS, OCR and so on.), Which are able to cause infectious-allergic bronchial asthma, the principal manifestations of which are a paroxysmal disordersBronchial patency. Symptoms indicating an exacerbation of asthma: an audible at a distance of wheezing, feeling short of breath, asthma attacks vary in intensity shortness of breath, dry cough.
