Allergies is an immune system disorder that
occurs when the immune system is overly sensitive to certain non-disease-causing substances
called allergens. Allergies can be described as a false alarm of the immune system. Allergies
can cause a variety of minor symptoms including runny nose, itching, swelling, or sneezing.
However, some severe allergies can cause hives, trigger asthma attacks, or create life-threatening
breathing problems. Some common allergens include:
Pollen Pet dander
Insect stings Certain foods
and Certain medications Family history of allergies, a lack of early
childhood exposure to allergens, and young age may increase the risk of developing allergies. Treatments include many over-the-counter antihistamines
including cetirizine, fexofenadine, and loratadine. Prescription steroids including prednisone
and methylprednisolone have also been used to treat severe allergies. Allergy shots,
also known as desensitization therapy, is often effective at preventing allergies. The easiest way to prevent allergies is to
simply avoid the offending allergen. Wash hands and clothes thoroughy after touching
a known allergen. Know and avoid drug and food allergies and exercise caution whenever
there is a chance you may be exposed to serious allergy triggers.
