What are Allergies?
Allergies are described as abnormal responses within the body to things or substances that are typically harmless. However, this incorrect response causes the immune system to react to the substance (known as allergens) as if it was harmful. The symptoms of allergies can make you feel miserable and rotten! It is a good idea for any allergy sufferer to get to know which allergens you are allergic to so that you can control the symptoms.
Allergies are extremely common and affect more than 20 percent of adults and children in the United States. According to the Allergy Report from the American Academy of Allergy, Asthma and Immunology, allergies are the sixth leading cause of chronic illness. It usually develops during childhood or early adulthood. Most allergies are inherited and people are more likely to have a tendency to be allergic if there is a family history of allergies or asthma.
Sometimes, people with allergies may experience a severe reaction known as anaphylaxis. The signs of anaphylaxis may start with severe itching of the eyes or face and develop into more serious symptoms such as swelling of the lips, tongue and throat, abdominal pain, cramps, vomiting, diarrhea, hives, and angiodema (hives in the throat). This type of reaction usually occurs within minutes after been exposed to the triggering allergen (such as a peanut). It is a rare, life-threatening emergency and medical attention is required immediately.
