Mold Allergies


Molds are tiny fungi whose spores float through the air. They like damp environments and need four things to grow: food, air, appropriate temperature and water. Molds can be found outdoors, in homes and other buildings.

When you inhale you breathe in mold spores from the air, but only some people have an allergic reactions or asthma symptoms if exposed to too much of this fungus.

Your immune system is overly-sensitive to specific mold spores and treats them as an allergen. When you inhale the mold spores, your immune system triggers symptoms such as sneezing, itching, watery eyes, runny nose, nasal congestion or itchy nose, mouth and lips.

There are hundreds of types of mold but not all of them are responsible for causing allergy symptoms. The most common allergy causing molds include Alternaria, Aspergillus, Cladosporium and Penicillium.


You can develop allergy symptoms outdoors on days when mold spores are in the air. You may have symptoms indoors if mold is in your home, school or workplace.


Symptoms include:

  • Itchy nose, mouth and lips
  • Sneezing
  • Itchy, watery eyes
  • Runny nose
  • Nasal congestion
  • Mold can also trigger asthma symptoms such as wheezing, shortness of breath or chest tightness.


Mold symptons often mimic symptoms of other conditions as well. Your allergist can diagnose whether mold is the culprit to your symptoms. A skin prick test gives accurate results in just a few minutes. Consult with your allergist about other mold tests.

Dear Patients,

Governor Wolf has asked all non-essential businesses to close for the next 2 weeks.

In compliance with Montgomery County and the Commonwealth of Pennsylvania, Drs. Martin and Nannapaneni feel that although allergy injections are important to your health and are recommended to many of our patients, the risk of catching COVID-19 by coming into the hospital/office outweighs the benefits of immunotherapy.  Our intention at this time is to resume injections on April 6, 2020. If that changes, we will update this message.

Our staff and doctors will be present during regular office hours to answer questions and take care of emergencies by telephone or otherwise on a case by case basis. Routine office visits will also be postponed until after April 6, 2020.

Refills for prescriptions and other concerns will be handled by telephone during regular office hours. Teleconference through Face Time will be implemented.

When tests for the COVID-19 virus becomes available, appropriate arrangements will be made.

We ask for patience and understanding during this time. Our utmost interest is the protection of our patient population, our employees and our providers.
