Basically when the immune system is triggered by a normally harmless foreign substance in the body, it develops into an allergy. The immune system ends up making antibodies to fight off the harmless substances but in the process these antibodies begin to produce symptoms because of the by-products of their existence such as histamine and the likes.
Typical triggers include the following.
- Airborne allergens such as mold, dust mites, animal dander and pollen.
- Specific food classes such as shellfish, milk, eggs, fish, soy, wheat, tree nuts, peanuts etc.
- Insect bites and stings like wasp sting, bee sting.
- Medicines like penicillin and derived antibiotics.
- Substance that you might touch like latex.
Risk Factors Involved
Depending on several situations you may or may not be at risk of catching an allergy.
- If your family has a history of allergies or even asthma, then you have a higher chance of catching some form of allergy. Most common include eczema, hay fever and hives.
- Children are most vulnerable to building an allergy than adults however, allergies in childhood tend to subside as the individual matures.
- Having another allergic condition is in itself sufficient to develop more allergic reactions to something else.
Allergies aren’t alone but they come with certain increased complications that can happen at any time.
- Anaphylaxis is probably your biggest concern if you have a verified allergy. This is simply a severe allergic reaction.
- Asthma is yet another allergy that can be a by-product of any form of allergy that you may have.
- Sinusitis or the infection of the lungs and ears happens usually when you have asthma or hay fever.
- Fungal complications of the lungs occur with several air borne allergens.
