Hay fever is a seasonal allergic disease, which manifests itself inwind-pollinated flowering plants.Often, it is worsening in the warm season, during the flowering shrubs, trees and plants, which is due to hit in the air a huge number of pollen.When inhaled, it enters the mucous human and can cause severe reactions in people prone to allergies.

Hay fever allergies manifested by symptoms:

  • bad cold and the difficulty of nasal breathing during certain flowering plants;
  • frequent sneezing;
  • itching and burning sensation in the nose;
  • tearing and swelling of the eyes;
  • itching, feeling cramps and a feeling of "grains of sand" in the eyes;
  • shortness of breath, cough;
  • swelling of the nasal mucosa;
  • itching and skin rashes;
  • asthma attacks in some cases.

Symptoms usually repeated over a long period in the same time of year, and may last from two weeks to five months.Self-healing does not hap

pen often, and marked only a partial reduction of allergy cases without conducting therapy.

With bouts of the disease each year are becoming longer and more severe.Danger pollinosis as allergies is that without proper treatment, it may develop into bronchial asthma.

Thus, hay fever may manifest as allergic rhinitis, conjunctivitis, atopic dermatitis, and have serious consequences for the patient in the form of asthma.In addition, the hallmark of hay fever is consistently recurring seasonal displays, which coincides with the dusting the plants on which man reacts to pollen.

Pollinoz children

Clinical hay fever symptoms can occur at any age, but most often it appears in children from 3 to 10 years.Quite often, the symptoms of hay fever in children are observed in cases of genetic predisposition, when the parents also suffer from this disease (atopy phenomenon).In addition, boys suffer more girls.

common symptoms of hay fever in children are:

  • alllergichesky rhinitis;
  • allergic conjunctivitis;
  • rinokonyunktivalny syndrome.

Allergic rhinitis is manifested frequent sneezing, itching, profuse nasal discharge and congestion.These symptoms may vary in severity.

Allergic conjunctivitis is characterized by itching and burning in the eyes, redness of the eyelids and lacrimation, photophobia, pain in the brow.In severe cases there may be blepharospasm, keratitis, erosion along the limb.

Rinokonyunktivalny syndrome includes symptoms of both diseases, and may be accompanied by loss of appetite, fatigue, sweating, insomnia, tearfulness.In severe cases of hay fever in children can develop asthma, which is characterized by attacks of breathlessness, cough, labored wheezing, feeling of pressure in the chest.

The disease in children can also occur in the form of urticaria and angioedema.And in severe hay fever in children and the massive concentration of pollen in the air, observed:

  • cardiovascular changes (tachycardia, hypertension);
  • irregularities in the digestive system (nausea, epigastric pain, unstable chair);
  • changes in the nervous system (headache, fatigue, sleep disturbance, increased body temperature).

pollen allergens during hay fever

seasonal exacerbation of hay fever due to certain life cycle of flowering plants.Therefore, if every year, at one and the same time, the patient develops symptoms of hay fever (eg, runny nose, itchy eyes, sneezing, watery eyes), then the most likely reason - it is pollen, blooming at this time.

On Earth, there are several thousand species of plants, but only fifty cause pollinosis.Each climatic region is characterized by the predominance of its plant species are able to cause allergic reactions.In our band of the most common allergens are:

  • weed pollens (ragweed, wormwood);
  • tree pollen (birch, alder, poplar);
  • pollen (chamomile, dandelion, sunflower);
  • some pollen grains (rye, bluegrass, ryegrass).

Most patients with hay fever allergy occurs only on certain types of plants and trees pollen.Therefore pollinosis accounted only for the duration of flowering, and the symptoms depend on the individual sensitivity, as well as on the amount of pollen in the air.

When an allergic reaction to one of the plants there is a high probability that the same reaction occurs and at other plants of the same family.Some patients are allergic to 2-3 formed a group of plants.If hay fever is an actual problem of cross-reactivity of patients to other allergens that are found in foods of plant origin.For example, a person who is allergic to birch pollen may observe similar manifestations in the use of hazelnut, potatoes, pears, peaches, celery, and other foods.

If an allergic reaction to pollen, you must be wary of herbal medicine, as well as the breeding of indoor plants.Moreover, each year, the number of significant increases allergens and allergies to them - are amplified.Therefore, the earlier a patient to see a specialist, the better the chance to stop and to facilitate the development of the disease.

During exacerbation in the peripheral blood, mucus cytogram nose, and sputum bronchial asthma manifests eosinophilia, indicating the presence of an allergy.And in the period of remission of hay fever are the main method of diagnosis allergological skin samples.

treatment of hay fever involves:

  • an elimination event;
  • diet therapy;
  • drug therapy;
  • specific immunotherapy.

an elimination event signify the termination or reduction of exposure to allergens that cause hay fever began.

Diet therapy involves exclusion from the diet of honey and a number of products (cross-reactive foods).

Drug treatment of hay fever include basic anti-inflammatory drugs, antagonists of H1 histamine receptors, and symptomatic agents.

Specific immunotherapy is conducting vaccinations against allergies.This method of treatment is carried out in the autumn-winter period and assumes a gradual "habituation" of the body to allergens by introducing them in small doses.Treatment pollinosis manner achieves and maintain a positive result for several years.

addition to the treatment of hay fever, allocate more physiotherapy treatment, as well as extracorporeal blood purification technique, which allows you to clean up the internal environment of substances that are involved and support the pathological processes in the body.
