Asthma Q & A

What is asthma?

Asthma causes swelling and inflammation of the airway passages in your lungs, making it hard to breathe and may trigger a cough.

In some people, asthma symptoms are mild and only occur under certain conditions, such as exercise or weather changes. However, others have asthma symptoms that occur daily and affect their quality of life.

Though there is no apparent cure for asthma, the experts at Allergy and Asthma Specialist Doctors, Inc., can develop a plan that helps you gain control over your symptoms and improve your quality of life. 

What are asthma symptoms?

Asthma symptoms vary in type and severity. Common symptoms of asthma include:

  • Wheezing when exhaling
  • Coughing
  • Shortness of breath
  • Chest pain or tightness
  • Difficulty sleeping at night

Even with treatment, your asthma symptoms may change or worsen over time. Regular visits with the experts at Allergy and Asthma Specialist Doctors, Inc., can help you stay on top of your asthma symptoms and prevent an asthma attack. 

What happens during an asthma evaluation?

When you come in to see the experts at Allergy and Asthma Specialist Doctors, Inc., with concerns about asthma, you can expect a comprehensive evaluation. 

During your exam, your provider reviews your symptoms, medical history, family history, and the types of medications you take. They also conduct a physical exam and perform diagnostic tests, such as:


During spirometry, your provider measures how much and how quickly you can exhale air after taking a deep breath. This test estimates the narrowing of your airway. 

Exhaled nitric oxide test

An exhaled nitric oxide test measures the amount of nitric oxide gas you exhale. High amounts of the gas may be signs of inflammation. 

The providers at Allergy and Asthma Specialist Doctors, Inc., perform the exhaled nitric oxide test to monitor the effectiveness of your asthma treatment plan. 

Allergy testing

The specialists also offer comprehensive allergy testing. Many people with asthma have environmental allergies that worsen their symptoms. Identifying these allergens may help you gain better control over your asthma.

How is asthma treated?

Your provider at Allergy and Asthma Specialist Doctors, Inc., develops a personalized treatment plan for your asthma based on the severity of your lung condition.

Treatment may include:

  • Long-term asthma control medications
  • Rescue inhalant medications
  • Allergy medications
  • Immunotherapy

The asthma specialists also help you develop your asthma action plan to know when to take your medication and increase your dose based on your symptoms.
