allergy symptoms

allergy symptoms photo allergy symptoms highly individual and very diverse.All observed in allergic reaction symptoms are directly dependent on which systems and organs of the human body had been exposed to the allergen penetrated. show numerous long-term observation, most often in the allergic process involves the skin, gastrointestinal tract and respiratory tract.

allergy symptoms in children are divided into slow reaction (period of manifestations ranging from hours to days) and the reaction of the immediate type (after contact with the allergen manifestations arise from the matter of seconds to several hours).However, this division is to some extent arbitrary, since it is assumed that the development of an allergic reaction always occurs immediately after the incident contact with the allergen, and the absence at first external manifestations associated with much more massive impact on systems and organs of the body, and therefore morelengthy formation of immune defense response.

For immediate allergic reaction include the following different severity and clinical symptoms allergic processes: hay fever (hay fever), atopic dermatitis, urticaria, asthma, allergic conjunctivitis, anaphylactic shock, allergic rhinitis, angioedema, serum sickness.Perhaps the most dangerous immediate type allergic reactions are anaphylactic shock and angioedema, which often develop after being bitten by bees and other poisonous insects.For example, angioedema may affect the occipital part of the spine, neck, face and cause suffocation in a patient who, without the provision of timely emergency care is usually fatal.Therefore, without exception, immediate type allergic reactions should be eliminated as soon as possible, taking advantage of skilled medical care.

Most often the doctor is faced with a complex clinical manifestations and symptoms caused by any allergen.Among the delayed allergic reactions want to stay at the cytotoxic reactions are due to involvement in the pathological process begins rapidly degrade blood cells, characterized by increased risk to human life.Due to the destruction of blood cells can develop diseases such as hemolytic anemia, and leukoplakia, but the greatest risk of causing thrombocytopenia, causing multiple internal and external bleeding.Diagnose cytotoxic reactions are particularly difficult becausethe patient usually does not associate with any drug or food allergen sudden hemorrhage caused ocular vessels, as well as appearing on the body numerous bruises.

reason for a number of different symptoms of allergies in children can become absolutely any allergen.For example, a patient with pollinosis child birch pollen allergen can cause not only rhinoconjunctivitis, urticaria and with bronchospasm.Allergic rhinitis or pollinosis caused by allergens which are present in the ambient air.This may be dust, animal fur or feathers, pollen.Allergy symptoms in hay fever: sore throat, sneezing, watery eyes, runny nose, itching in the nose and throat.

Skin allergy symptoms .The most common skin symptoms develop after consuming the allergen with food.Usually it refers to seafood, milk, eggs and citrus.It is also often the cause of skin symptoms may be medications and pollen.Typically, allergic skin manifestations developing over forty-eight hours from the moment of contact with the allergen and are accompanied by symptoms such as rash, itching, redness, fluid-filled blisters, swelling.In humans with contact dermatitis, skin allergy symptoms begin to appear only after several days of contact with the allergen and exclusively at the contact point.Some allergens if they are getting a healthy skin in small quantities, may themselves express themselves only a week after contact.How to plant, a new contact allergen sensitive body produces at least ten days.

Symptoms of acute allergic contact dermatitis: the appearance of itchy papules and vesicles, the development of the character wearing lishaynyh platelets.There have been documented cases of allergic contact dermatitis lesions all parts of the skin - erythroderma, exfoliative dermatitis.

also skin symptoms of allergy include atopic dermatitis and urticaria.Hives rash appears unstable in the form of convex or flattened reddish itchy irregular shape.In most cases, urticaria develops due to contact with allergens that are contained in medicines, food and the air.

There is also a group of allergic diseases of the skin, under the general title - allergic dermatitis.These diseases can develop as a result of penetration into the body by injection administered through the mucosa of the gastrointestinal tract, or directly in contact with the skin cosmetic and / or medicinal products, food products, metals, latex aeroallergens, household products and so on. Often, allergic skin reactions developin response to emotional disorders and insect bites.Symptoms of allergic dermatitis: 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 allergic reaction is anaphylactic shock.Symptoms of anaphylactic shock: the appearance of a rash all over the body, the occurrence of seizures and sudden shortness of breath, loss of consciousness, involuntary defecation and urination.Symptom allergy - anaphylactic shock, develops not later than five hours after the penetration into the body of the allergen.In the case of the slightest suspicion on the development of the state should promptly call emergency services.

allergy symptoms from the respiratory tract are caused not only aeroallergens, and infections (candida, neisserial, chlamydiosis, pneumocystis, mycoplasmosis, SARS, acute respiratory infections and so forth.), Are able to cause infectious-allergic asthma, the main manifestations of which are paroxysmalviolations of bronchial patency.Symptoms indicating the worsening of asthma: audible at a distance of wheezing, feeling short of breath, asthma attacks, varying in intensity shortness of breath, a dry cough.
