To understand this, you should know that your body has a defence system to fight disease and protect itself. Just like the army protects a country from enemies. In medical language, your body's defence system is called the immune system. When harmful things such as germs (bacteria or viruses) enter your body, the immune system recognises an "enemy" and attacks it.
But sometimes your immune system gets confused about what is an enemy and what is not. It reacts to harmless things like dust, the hair of animals, the pollen from plants and trees, and sometimes even certain food items.
An allergy can affect various parts of the body such as the skin, eyes and nose. If it affects your nose, you sneeze a lot, your nose itches and gets runny and blocked, and your eyes keep watering. These are called the symptoms of allergic rhinitis.
Is It Allergic Rhinitis or Just a Common Cold?
Allergic rhinitis is caused by allergens, whereas a cold is caused by germs. Both these problems can make you sneeze, and make your nose run and feel blocked and itchy. But there are some signs that can help to tell the difference. It is probably allergic rhinitis if:
You do not have fever and body ache (ache in the muscles)
The mucus in your nose is clear and runny, not yellow/green and thick
You sneeze many times before the sneezing attack stops
Your nose, ears and throat feel itchy
Your eyes water a lot
These problems stay longer than a typical cold.
Is Allergic Rhinitis a Serious Condition?
Though allergic rhinitis does not threaten your life, it can certainly disrupt your life! It disturbs your sleep, your performance at school or work, and you feel and look miserable. How can you lead a normal active life if you are conscious about constantly sneezing and blowing your nose?
