Some people, seemingly “harmless” plants or animals can cause severe allergic reaction. Some people with the coming of spring, rejoice in the blooming flowers and trees, while others suffer from runny nose, stuffy nose and watery eyes caused by reaction to pollen. Some allergic reaction appears on food or house dust. Why is this happening and how dangerous it is to ignore the Allergy?
Why is an acute reaction to allergens
Allergens are substances which cause human acute immune response. Still, doctors do not have an absolute answer, what exactly is a key factor in the occurrence of allergies. Sometimes an allergic reaction may be bright. And sometimes the symptoms are so weak that the person does not even suspect yourself of allergic reaction to something. Immunologists say that a hereditary factor is the leading role in the development of allergic reactions. Increased excitability of the immune system in response to some foreign substance (pollen, animal dander, food, etc.) due to a certain set of specific genes and passed from parents to children.
In recent years, the number of Allergy sufferers is growing: doctors associated this fact with poor ecology and lots of genetically modified foods, and excessive “sterile” to some people whose immunity is suppressed and does not adapt to the constant fight with gets in the body viruses and bacteria. Some food “allergies”, especially in children of younger age have nothing to do with failures in the immune system. Skin rashes and other allergic reactions to products associated with malnutrition of children and problems with the digestive system.
The most common allergens
When the allergen enters the body, there is an active production of antibodies (produced by sensitized lymphocytes). Then there is the inflammatory reaction and produces histamine – an organic compound, the mediator of allergic reactions. Therefore, the Allergy medications called antihistamines. And in the final stage of allergic reactions under the influence of allergens on cells and tissues begin to show clinical signs – rash, itching, cough, runny nose, etc.
Most often allergens become pollen (hay fever), food, mildew, insects (when they bite), animal dander, house dust, which is full microclima etc. Also allergies can cause the cold and Vice versa – the sun, medicine, synthetic clothes. To identify the allergen, you can take special test. Treatment of allergic reactions do the immunologists and allergists.
Do I need to treat allergies and how to avoid reaction to the allergen
The less people in contact with the allergen, the lower the risk of allergies. It is therefore important to monitor the cleanliness in a house or apartment to deal with the resulting mold, wet cleaning and to minimize the amount of things that accumulate dust, to avoid some foods (especially important to feed the children according to their age). In the season of mass flowering is better not to go to the woods or field, if exposure to allergens cannot be avoided, then it is important to choose an antihistamine and take it.
The most dangerous complications of an allergic reaction is angioedema and anaphylactic shock. Especially dangerous oedema larynx in which a person can suffocate. If he can’t provide medical care. If anaphylactic shock, sharply falling blood pressure, impaired breathing process, the person loses consciousness. Both conditions require immediate hospitalization. If the Allergy is not treated, it may develop bronchial asthma, skin lesions (dermatosis), etc.
