Seasonal allergies

seasonal allergy Photo Seasonal allergies - allergic reaction, which is a protective response of the immune system to various foreign impurities in the inhaled air.In most cases, an allergic reaction to allergens is observed, contact with which there is the fresh air, is usually mold and pollen.

Seasonal allergies in children usually manifests itself at certain times of the year, but occasionally can occur year-round and, in the case of constant contact with the allergen.Typically, the allergic reaction manifested seasonal rhinoconjunctivitis (conjunctivitis) and allergic rhinitis, or seasonal pollen asthma.

If the child has an allergic reaction can be traced to the fruit juice and puree, spring and summer should be especially careful, becauseIn this case, after three years of the baby can develop seasonal allergies to pollen.When viewed superficially, at first glance between dandelion and melon, carrots and alder have nothing in common.However, conducted numerous biological studies have shown

that in the pollen and fruit plants are present have the same areas of protein molecules, which are the cause of cross-allergic reactions.If the baby cheeks blush of cherry jam, it is possible that he will sneeze and cough after a walk in the birch grove.But if the child is present are allergic to citrus, then a bad cold he can cause a bouquet of daisies

Seasonal allergies - causes

Like all other allergies, seasonal allergies caused an attack of immune protection allergens enter the body through the skinwith food or inhaled air.When seasonal allergy triggers allergy reactions, along with the inhaled air fall on the mucous membranes of the respiratory tract (lungs, throat, nose and mouth) and eyes.Most often determine the specific allergen is very difficult.After the start of provoking allergen contact with mucous membranes, the white blood cells to these foreign substances begin to produce antibodies, which in consequence leads to the development of an allergic reaction, which is sometimes called hypersensitivity to intrinsically harmless substance.

Pollen is the most common allergen in seasonal allergies.Pollen - formed in the flowers (the male part of the reproductive organs of flowering plants) microscopic particles.Pollen is carried by wind-pollinated plants with the movement of air, pollinating (fertilizing) other plants of its kind.Depending on the local climate, for each plant species observed a certain period of release pollen.Some plants are pollinated in the spring, others in summer or beginning of autumn.And the farther north, the period of pollination occurs later.Pollen some grasses, trees and weeds (ragweed, etc.) As the cause of allergic reactions likely than others.Pollen insect-pollinated plants are much less allergen than the pollen of wind-pollinated.

Molds are another fairly common allergen.Mould - quite a large group of families of fungi that do not form fruiting bodies.Fungal Spores unlike observed pollen in the air is constant, and the concentration depends on the current conditions rather than on the season.Molds are extremely common and can be found both outdoors and in agricultural and residential areas.They thrive in the soil, wet wood and decaying plant debris.In areas they often live in places where the air does not circulate freely (bathrooms, attics, basements, etc.).

Risk factors for seasonal allergies include: the presence of allergic diseases in blood relatives, asthma, eczema, repeated contact with the allergen, polyps of the nasal cavity.With age, the type of allergens, which are allergic, can change how often changes and the very symptoms.

periods of seasonal allergies:

• Spring - flowering hazels, sycamores, maples and birches

• Summer - the period of flowering of flowers and grass

• Autumn - during flowering Asteraceae (wormwood, quinoa, ambrosia)

Allergiesseasonal - symptoms

Manifestations of seasonal allergies are not always terrible.Some people have an allergic reaction is well tolerated, with no appreciable change in appearance and heavy cold.In this case, change the settled rhythm of life is not worth it.However, there may be enough and severe cases of allergic reactions that require mandatory visits to the allergist.However, even if the symptoms of seasonal allergies expressed quite weak, the treatment is still necessary to carry out, as the first picture of the implicit, can begin to progress, moving gradually to asthma and autoimmune diseases.

main symptoms of seasonal allergies: runny nose with the release of liquid transparent discharge, sneezing, nasopharyngeal leaking, nasal congestion, a feeling of stuffiness in the ears (ear), bloodshot watery eyes, insomnia, lack of energy, fatigue, burning and itching in the nose, irritation of the conjunctivaand soft palate, a rash on the different areas of the skin (between the toes, in the abdomen, groin, etc.)

In the case of seasonal allergy symptoms appeared to delay the visit to the doctor is not necessary.Using a simple procedure with a qualified allergist easily determine the type of plants, adversely affect health.The very diagnosis is to conduct skin tests with a set of the most common in the place of residence of the patient pollen allergens

Seasonal allergies - treatment

Fortunately seasonal allergy specialist treatment is not always required, and it is often quite enough of simple hygiene and avoid contact withprovoking allergen.If these measures were not enough, in any pharmacy you can buy anti-allergic drug.

care at home

necessary to avoid contact with suspected or already known allergens.This is achieved by setting the security room air filters.It should also be careful to close the doors and windows, and in the case of imminent contact with an allergen, it is necessary to use protective bandage on his nose and mouth, as well as gloves.

should be as often as possible to take a shower, change clothes, wet cleaning.You should also get rid of the curtains, rugs, carpets and other things that can accumulate large amounts of dust.

If you have mild symptoms fairly well to wash the nose and throat rinse lightly salted warm water (200 ml of water, 2 tbsp. Spoons of salt).To relieve itching in the throat, eyes, and to reduce a cold can take non-prescription antihistamines (diphenhydramine and so forth.), But be aware that these drugs have decelerated effect and their reception is absolutely contraindicated in the management of motor vehicles or other vehicles and mechanisms of increased danger.

In the case of failure of simple measures in acute or persistent symptoms, you need to conduct drug treatment, not only to eliminate and alleviate the symptoms, but also to prevent them.

treatment of seasonal allergy medications

Corticosteroid nasal sprays fluticasone, triamcinolone, beclomethasone, in the vast majority of cases turn out to be the most effective.Due to the fact that they are applied topically in dosage insignificant data sprays almost completely devoid of adverse effects which are characteristic for corticosteroids.Also sprays successfully relieve swelling, eliminate itching and nasal congestion, do not cause drowsiness.To achieve sustainable impact, they should be taken daily for several days.

Even some common medications prescribed for the treatment of seasonal allergies are antihistamines, which in most countries are in the sale of non-prescription (Hydroxyzine, diphenhydramine, tripelennamine, Clemastine).All of these antihistamines are relatively inexpensive and are located in the free market, but the effect achieved is kept relatively short, and besides, they have a strong sedative effect, so that they are absolutely contraindicated people from whom, because of their professional activities require quick response.We would also like to note that in the case of continuous use over time is reduced sedation, but this applies also antiallergic effect.Alternatively, you can use these long-acting drugs like desloratadine, loratadine, fexofenadine.Despite the fact that they are expensive and usually available only by prescription, they should only be taken once a day, and sedation after taking almost not felt.
