Allergens that trigger allergies only affect people who have allergies. In others, such allergens will not trigger an immune response. Several types of substances that can cause allergic reactions include insect bites, dust mites, animal dander, medicines, certain foods, and pollen.
When the body first encounters an allergen, the body will produce antibodies because it thinks it is dangerous. If the body returns to contact with the same allergen, the body will increase the amount of antibody to the type of allergen. This is what triggers the release of chemical compounds in the body (histamine) and cause allergic symptoms.
There are some common allergy symptoms, among others:
- Hard to breathe.
- Rash on the skin.
- Runny nose.
- There is swelling in the body that passes allergens, such as face, mouth and tongue.
- Itching and red on the eyes.
- Red, watery eyes.
- Abdominal pain, vomiting, or diarrhea
The severity of allergies also varies among people, some have mild allergic reactions and there are severe to fatal results called anaphylaxis. If you have anaphylaxis, you need emergency medical attention.
The most powerful way to prevent allergies is to avoid the substance of the trigger or allergen. But if the symptoms of allergies already appear, there are some anti-allergic drugs that can help.
