Seasonal allergy (hay fever, hay fever) is an excessive (damaging its tissues) reaction of the immune system to pollen. As a rule, it occurs in spring and summer, a little less often in autumn. During these periods of the year shrubs, trees and grasses, pollinated by the wind, bloom. Microscopic pollen carried by the wind gets on the skin and mucous membranes of an allergic person and provokes inflammatory reactions, followed by unpleasant symptoms.
How to protect yourself from allergies, when to see a doctor, and which home remedies for allergies deserve your trust – we will tell you in this article.
What are allergic reactions?
Depending on the location (“localization”) of the inflammatory process, reactions are divided into several types:
- Skin form (allergic dermatitis);
- Respiratory form (allergorinitis, pharyngitis, laryngitis, bronchitis, and bronchial asthma);
- Ophthalmic manifestations (conjunctivitis, blepharitis, keratitis).
In some cases, against the background of hay fever, cross forms of food allergy occur with the development of gastrointestinal symptoms. For example, if you are allergic to birch pollen, you are allergic to hazelnuts, apples, peaches, and carrots; when reacting to cereals – to sorrel; when reacting to wormwood – to citrus fruits, sunflower seeds, honey. In such cases, symptoms of allergic gastritis occur – abdominal pain, nausea, diarrhea.
Seasonal allergy symptoms.
In the mucous membrane of the mouth and nose, there are macrophages – immune cells that are activated when a pathogen (pollen) hits them and trigger an immune response leading to inflammation. The manifestations of hay fever differ significantly depending on age, type of reaction and severity, duration of pathology. Open the next page to read symptoms.
