Allergies are caused by the body's immune system producing
antibodies to protect against foreign substances that may cause
sickness or infection.
The severity of allergies ranges greatly, and varies from person
to person. Most of the time, allergic reactions have minor
symptoms. However, when a reaction is severe, it involves several
of the body's organ systems, and may cause life-threatening
reactions in the body. If this occurs, contact 911 immediately.
Common triggers of allergies are: certain types of foods, insect
stings, medications, and airborne substances like pollen, dander,
and dust mites. The symptoms of allergies differ, based upon the
- Airborne Substances: Congestion, runny nose,
itchy and watery eyes.
- Certain Foods: Tingling mouth, swelling of
lips, tongue, face or throat, and hives.
- Insect Stings: Swelling around the sting site,
itching or hives, cough, tightness in the chest, wheezing, and
shortness of breath.
- Medication: Hives, itchy skin, rash, facial
swelling, and wheezing.
Allergy medications, allergy shots, and epinephrine shots all
help to reduce the reaction of your immune system and ease allergy
symptoms. Visit the nearest MedExpress location to discuss these
options with a medical provider.
