10 Important Facts about Allergies

An allergy is caused by an allergen, a foreign substance that causes an immune system reaction. It is commonly triggered by food, a drug or an object like an untidy carpet or fur from your pet dog or cat. An allergic reaction brings about symptoms like coughing, sneezing, itchy eyes, runny nose, and scratchy throat. It can also cause rashes, hives, low blood pressure, breathing problems, asthma, or even death.
