Could you have allergic asthma?

Asthma is a chronic and serious lung disease. It causes swelling and narrowing of the airways, making breathing difficult. Asthma has no cure. But most people with asthma can live active lives with the appropriate asthma treatment plan and an ongoing partnership with their doctor.  Read more about allergic asthma by clicking here.

"Why are my allergy symptoms worse than ever before?"

Many people are experiencing severe allergy symptoms right now and many of them are asking "why are my symptoms more severe than ever before?"

The answer may be due to the "priming effect".

The "priming effect" is an increased sensitivity of the lining of the nose that occurs with repeated exposure to allergens like pollen.

With the hot weather occurring earlier in the year this year and sticking around longer than usual, there has been more pollen in the air (plants produce more pollen in hotter weather).

This has meant a longer allergy season and a therefore a more vigorous "priming effect" that has become stronger and stronger as the different seasons have progressed.

 

So a person doesn't need to be exposed to as much pollen to have symptoms of hay fever (also known as seasonal allergic rhinitis). These symptoms include sneezing, runny nose, nasal congestion, scratchy throat, watery/itchy eyes and even fatigue. All of these can greatly affect quality of life and can lead to complications like sinus infections and asthma flares.

 

People who've never had seasonal allergic rhinitis symptoms before may experience them for the first time. Others who could control these symptoms with over the counter medications like antihistamines now need additional medication to help symptoms.

We are currently in the fall allergy season where weeds and molds are the main culprits that cause symptoms. Elm tree pollen is also important here in So Cal this time of year. The "priming effect" can also cause patients to be more sensitive to other allergens like dust mites and animal dander.

The most important thing for patients to know is: don't ignore your symptoms! If allergen avoidance and over the counter medications are not enough, go see an allergist to discuss other options and to develop a treatment plan that is right for you!

Weather and asthma

Abrupt changes in temperature, humidity, barometric pressure, high ozone levels, or strong winds can aggravate asthma.

Common asthma triggers

Asthma is most commonly triggered by "colds" (viral respiratory infections), or inhaled allergens such as dust mites, pollens, or pet danders.   However, many children and adults with asthma find that intense exertion will also trigger chest tightness or cough due to asthma, especially running for long distances.  Breathing very cold or very hot air, especially if under dry or windy conditions, will also frequently trigger bronchospasm, as will any type of irritant that is inhaled (smoke, paint fumes, perfume scents, etc.); sometimes a frozen drink or ice cream will be the trigger.

Once a trigger is identified, there are ways to avoid it or to at least control the situation.  Your allergist can help identify the triggers that are important to you, and advise on safe options for preventing future asthma attacks.
