Graphic of Allergy Facts, Figures and StatisticsAs you probably already know, an allergy is a natural response of your immune system when you come into contact with a foreign substance that it considers to be harmful.

This irritant can enter the body either through the lungs, stomach, injection or by touch.

Reactions to allergies can range anywhere from a simple cough, runny nose, itchy eyes or sneezing, to more serious issues like hives, breathing trouble or choking, and even death.

Currently, there is no cure for allergies. The only way to mitigate the associated problems is through prevention or treatments.

Here are the common methods:

  • Nasal allergies can be treated with medication and/or the use of a home air purifier. Air purifiers designed for allergies are excellent at removing the harmful irritants from the air that cause symptoms.
  • The best treatment for food allergies is abstaining from eating the allergy-inducing food or anything that has come into contact with it.
  • Drug allergies and insect stings often require quick medical attention to prevent any severe health issues.

Below, is a list of the top allergy facts, figures and statistics. This list will help shine some light on how many people actually suffer from different types of allergies, sickness and death facts, the costs associated with the disease and more.

If you’re curious about what causes allergies in the first place, you can read our article What are the Causes of Allergies to find out more.
