Although it’s hard to avoid everything that triggers fall allergies, there are many things that can be done to limit or treat the side effects so everyone can enjoy the season.

What allergies present in the fall?

Dirt-based molds are the main trigger of fall outdoor allergies. Mold is in decaying that plant material in yards and parks, as well as in pumpkin patches, hay and barns. Because we tend to close up our homes as the weather gets worse, inside allergens may get worse. Indoor mold, dust mites and our pets can trigger symptoms.

How do I know I have fall allergies?

Symptoms are the same as you might experience in the spring. Congestion, sneezing, post-nasal drip and itchy, watery eyes are the most common signs of fall allergies.

For many, spring is time to celebrate the end of constant rain and cold weather. For those with allergies, however, spring signals the beginning of misery. Often it starts with a little runny nose and tickle in the throat, but then becomes constant congestion, itchy eyes and nose and coughing.

Seasonal allergic rhinitis, or “hay fever,” affects more than 20% of people in the United States. Allergies are triggered by allergens such as pollen or mold spores. Many trees, grasses and weeds contain small and light pollens that are easily carried by the wind, causing allergy symptoms to flare up during their pollination season.

Unless an allergy sufferer decides never to go outside during the allergy season, preventing exposure to pollens will be difficult. Some tips that can decrease exposure include keeping the windows closed when pollen counts are high, washing hands and face after coming indoors or showe...

Dr. Peng was very informative and empathetic through out the whole appointment. she was very patient with my daughter who was crying for the last 10 minutes of her appointment when Dr. Peng was trying to give me information regarding our allergy results. I can see why Dr. Peng is highly recommended.

I am on disability and could not afford the inhaler she gave me. I [...] have limited funds. And, I was not instructed on what to do if I have one of these attacks again.

Dr. Peng is wonderful.

Dr. Peng has been seeing our daughter since small and is great.

I really like Dr. Peng's manner. She is personable, friendly, very informative and attentive. I really enjoy her sense of humor, bedside manner and conversational style.

As excellent provider.
