Allergy Statistics in the US

An allergy is an overactive response from the immune system after exposure to an allergen. If you have seasonal or environmental allergies, this can cause symptoms such as runny nose, nasal congestion, sneezing, nasal inflammation, and itchy and red eyes. If you have severe allergies to food, medications, insect or latex, it can lead to life-threatening symptoms that affect multiple body organs, including the skin, respiratory system, stomach and heart.

Several conditions fall under the umbrella of allergies, including allergic rhinitis (sometimes called “hay fever”), food allergies, anaphylaxis, allergic skin conditions, and allergic asthma.
