Allergies should not be considered a relatively recent disease. Even when there were no environmental problems, there were, for example, diseases such as hay fever and urticaria, which, in fact, are an allergic reaction to external stimuli. The increase in the number of people suffering from allergies is associated with a decrease in immunity caused by many factors, including poor ecology.

How does allergy arise?

Sometimes an allergy is inherited and can develop in 25% of cases if one of the parents suffers from it, but when they are both allergic, the probability of this disease in a child is 75-85%. But an allergic reaction to house dust, mold, insects, pollen, household chemicals, animal hair, medicines, etc., can appear suddenly and immediately become chronic. Unfortunately, cases when the allergy suddenly goes away are much less common.

The listed pathogens are allergens, when they enter the body, an allergic reaction can begin, which has several stages. At the first stage, the body recognizes the allergen as a foreign substance and begins to produce antibodies or special lymphocytes to it. This is a natural defense reaction that helps the body subsequently to recognize the danger and fight it.

When the allergen gets in again, the immune defense mechanism turns on and histamine and similar chemicals are released into the blood in large quantities, which are essentially poisons that block the action of the allergen. In the event of a failure of the immune system, too much histamine is produced in the body and, in turn, becomes the culprit for allergies, which damages cells, tissues and even organs.

Diathesis, dermatitis, bronchial asthma, Quincke's edema and anaphylactic shock are all manifestations of allergies.

How does allergy manifest?

Different allergens can provoke the appearance of different symptoms, in general cases, a person begins to sneeze and cough, even suffocate, the eyes begin to turn red and watery, photophobia, itching of the mucous membrane and dark circles under the eyes may appear. Many patients note a headache, the appearance of rashes on the skin - urticaria, in severe cases, anaphylaxis may develop.

Seasonal allergies can be treated with drugs. In cases of exacerbation, you should keep the windows in the house tightly closed.

In cases of food allergy, adults and children may experience suffocation, itching in the mouth, nausea, vomiting, colic, and even anaphylactic shock. In infants, there are cases of milk allergy - the body's reaction to lactose. It can present with irritability, swollen lips, bloating, bed-wetting, and other symptoms that resemble seasonal allergies - runny nose, red eyes, sneezing. Seasonal allergies are usually associated with the flowering time of certain plants, a reaction to the presence of pollen in the air.
