A Few Facts About Allergies

Allergies, which are extremely common today, can be caused by just about anything. They can be caused by something that touches your skin thus giving rise to a rash, anything you swallow or even inhale. It can vary in intensity, ranging from mild to severe. A mild allergy can be like a runny nose, itchy eyes and sneezing, whereas a more severe attack would be something like asthma, where this is often caused by the person inhaling something into the lungs or even an insect sting, shellfish allergy etc. The severe or life threatening kind of allergies are known as anaphylaxis and they give multiple symptoms such as breathing difficulty, difficulty in swallowing, dizziness or sometimes even loss of consciousness, the lips swell along with the tongue and throat. These kinds of allergies need immediate emergency treatment as they can result in shock and even death. These allergies, fortunately, do not occur very often. However, they can be treated successfully if treated properly.

Allergies are also known to set off other complications like ear infections and sinus infections. For example, an allergy that causes an inflamed nasal passage could lead to sinus infection and an allergy that causes an inflamed ear could lead to an ear infection.

Allergies are said to be hereditary. However, it does not mean that just because your mother or father has an allergy that you are most definitely going to get that particular allergy, it is just that, the chance of you getting any allergy is much higher.
