Asthma Q & A

What is asthma?

Asthma is a chronic lung disease that, in some situations, can be life-threatening. If you have asthma, it means there’s inflammation or swelling in the airways in your lungs. This makes it hard to breathe during an asthma attack.

Around 20 million Americans have asthma. Of these, 10 million have allergic asthma, including three million children.

What are the symptoms of asthma?

Symptoms of asthma typically include:

  • Cough
  • Chest tightness
  • Shortness of breath
  • Wheezing

These symptoms affect you during an asthma attack, which happens when you encounter a trigger. Some of the most common asthma triggers include:

  • Allergens
  • Smoke
  • Strong odors
  • Weather changes
  • Viral or sinus infections
  • Exercise
  • Acid reflux
  • Medications
  • Food
  • Emotional anxiety

The most common form of asthma is allergic asthma, where the trigger is allergens like pollen, mold, dust mites, and pet dander.

How is asthma diagnosed?

South Bay Allergy and Asthma Group uses several forms of testing to diagnose asthma.


One standard lung function test is spirometry, which measures how much air you breathe in, how much you breathe out, and how quickly you breathe out.

Nitric oxide test

Another test measures exhaled nitric oxide. This test calculates how much nitric oxide gas you have in your lungs. High levels in your breath indicate that you have inflammation in your airways, which is a sign of asthma.

The doctors are also experts in exercise-induced asthma (EIA) and vocal cord dysfunction (VCD). They offer treadmill exercise testing to diagnose EIA and VCD.

How is asthma treated?

Your provider at South Bay Allergy and Asthma Group can identify your allergic triggers, and develop a personalized treatment program to help you avoid those triggers as much as possible. 

It isn’t always possible to completely avoid allergens, so they also provide the most effective treatments available, including state-of-the-art biologic medications for moderate to severe asthma.

One way to control allergic asthma is by taking a medication that binds with the IgE antibody. The IgE antibody plays a key role in causing the inflammation in your airways that affects your breathing. Binding the antibody stops it from setting off the inflammatory response, preventing asthma attacks.

Another treatment for allergic asthma is allergy immunotherapy, which involves having regular allergy shots. If you have severe asthma, you might have to inhale steroid medication or take oral steroids during a flare-up.

Everyone who has asthma should carry an inhaler with them wherever they go, in case of an emergency.
