Healthcare 101: What Are Allergies? What is the Origin and Why Do We Get Them?
As the weather warms up, allergy season enters overdrive. All that plant pollen floating through the air and sticking to every surface causes many people to experience runny noses, itchy throats and watery eyes. So what causes these allergies anyway? Understanding how allergies work can help you find treatments that work best for you.
Understanding the Immune System
The role of the immune system is to protect the body from foreign invaders. There are numerous types of immune system cells that travel throughout the bloodstream. A critical component of the immune system is the ability to determine what is good for your body and what is harming it. When something is detected that could hurt your body, the immune system makes antibodies that attach to the harmful cell. These antibodies signal other cells to attack or destroy the invader.
How Allergies Work
The word “allergy” comes from ancient Greek terms for “other work.” This refers to the tendency of some immune systems to experience abnormal reactions to ‘normal’ items in their environment. Originally, scientists believed that all types of sensitivity were allergic reactions. Now, researchers have discovered the specific cells that contribute to seasonal allergies.
A healthy immune system easily distinguishes between harmless compounds and those that trigger disease. In people with allergies, however, these signals get mixed. Suddenly, objectively harmless compounds — such as pollen — get flagged as harmful invaders. The immune system then creates antibodies to target that particular allergen. This means that the next time you are exposed to the allergen, the immune system attacks.
An immune system response to the allergen involves the release of histamines, which leads to the classic allergy symptoms of sneezing, itchy nose or eyes, runny nose and watery eyes. This reaction persists each and every time you come into contact with the allergen in the future. For people who suffer from seasonal allergies, this histamine response may continue throughout most of the spring season.
How Allergy Medications Help
Fortunately, there are medications that prevent the immune system overreaction from occurring. Many allergy medications are antihistamines, which block the histamines being released by your body. This prevents you from developing the allergic response. Antihistamine medications are available in over-the-counter or prescription format. Your medical care provider can help you determine which medications are most appropriate for your allergies.
