What is an Allergy? - Basic Principles of Allergy

Is it a Cold or Allergies?

Allergic conditions account for 40% of absences in the work field and many of our patients have noted that although they’re not “sick” their symptoms can affect their work and even the quality of their life. Allergies occur when your immune system goes haywire. Our body protects itself from invading germs and other organisms with a complex set of proteins, blood cells and other defenses which work together to form the immune system.


Relief you need, specialized care you deserve!

Our specialists can effectively control your asthma and allergies by accurate diagnosis, skill and patience.
