5 Common Allergy Triggers

Allergies are an immune system response where the body’s defenses react to a substance in the environment. Countless things can trigger an allergic reaction, which can range from mild to life-threatening. Here are 5 of the most common triggers for allergies.

1. Pollen: Grass, tree and weed pollen can trigger allergies or hay fever. Pollen causes such symptoms as itchy, watery eyes, runny nose, sneezing and congestion--which can be prevented by staying inside when pollen counts are high, running the air conditioning and keeping the windows closed.  Treatments for these allergies include prescription drugs, allergy shots and over-the-counter products.

2. Animal dander: Proteins in an animal's saliva and skin can cause allergic reactions. If you find that your pet is causing allergies, wash them regularly, avoid carpets if possible and keep them out of your bedroom. Allergy shots can also be helpful.

3. Dust mites: Dust mites live in house dust and feed on the dead skin cells of humans and pets. You can prevent dust mite allergies by keeping mattresses and pillows covered and washing sheets in hot water every week.

4. Molds: Molds produce allergens and sometimes even toxic substances. Touching or inhaling mold can cause allergic reactions in people who are sensitive to it. Mold needs moisture to grow, so be sure to keep moist areas in the home well ventilated.

5. Food: Foods that commonly cause allergens include nuts, wheat, shellfish and milk. A reaction usually occurs right after eating the allergy-causing food, and symptoms include vomiting, hives, breathing problems, swelling and diarrhea. The best way to avoid these symptoms is to of course avoid offending foods completely--but if exposed and the reaction is life-threatening, an epinephrine injection may be needed.

If you discover you have allergies that begin to interfere with your everyday life, see a medical professional.  In most cases, allergies can become very manageable with the proper treatment and care.
