Is It Allergies or Sinuses... Let's take a Look Part 2
as allergies go, their official name is allergic rhinitis and they share some of the same symptoms but here is the difference.
Allergies are caused by an allergic response to allergens, such as pollen, dust mites or pet dander. This reaction happens when your immune system releases chemicals, such as histamine, into your bloodstream. These immune system chemicals lead to your allergy symptoms.
One of the key ways to tell if you are experiencing allergic rhinitis is if you have itchy, watery eyes along with your other symptoms. Itchiness is rarely a symptom of a sinus infection. Another way to tell the difference is if you have very thick yellow or green nasal discharge. That is more likely a symptom of a sinus infection. Allergies are the body's reaction to allergens in the surrounding environment. These allergens may include dust, pollen, mold spores, pet dander and food. People may be allergic to one or more of these items, so determining the cause of an allergic reaction can be difficult.
When someone is exposed to an allergen to which he is sensitive, his body produces histamines, a chemical that causes the lining of the nose, sinuses and the eyes to become inflamed. These linings produce a fluid in an attempt to fight off the allergen. When this happens, the person begins sneezing and wheezing. His eyes may start watering and itching. These symptoms last as long as the person is exposed to the allergen.
