Food Allergies


A food allergy is an abnormal response to a food triggered by your immune system. Foods that you have eaten for years without problems can cause allergies.

In children, the problem foods that most often trigger allergic reactions include eggs, milk, peanuts, tree nuts, soy, and wheat. Problem foods for adults include fish, shellfish, peanuts, tree nuts, and walnuts.



Symptoms of food allergy include:

  • Itching and swelling in your mouth
  • Vomiting, diarrhea, or abdominal cramps and pain
  • Hives and eczema
  • Tightening of the throat and trouble breathing
  • Drop in blood pressure

Your doctor may use skin and blood tests, elimination diet, and a detailed history to diagnose a food allergy.

The best way to prevent symptoms of a food allergy is by avoiding the food entirely. Consult your health care provider to help identify which foods you are sensitive to and eliminate them from your diet.

Many packaged foods are processed in facilities that contain nuts, soy, and wheat. It is important to read all labels before consuming the food. Restaurants may prepare foods with milk, eggs, or wheat and cook with peanut oil. Don’t be shy to ask questions to ensure the safety of your friends and family. Individuals can wear a medical alert bracelet or necklace and carry an auto-injector device containing epinephrine (adrenaline).

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.
