What Is Asthma?

According to the National Institutes of Health:

Asthma (AZ-ma) is a chronic (long-term) lung disease that inflames and narrows the airways. Asthma causes recurring periods of wheezing (a whistling sound when you breathe), chest tightness, shortness of breath, and coughing. The coughing often occurs at night or early in the morning.

Asthma affects people of all ages, but it most often starts during childhood. In the United States, more than 25 million people are known to have asthma. About 7 million of these people are children.


To understand asthma, it helps to know how the airways work. The airways are tubes that carry air into and out of your lungs. People who have asthma have inflamed airways. This makes them swollen and very sensitive. They tend to react strongly to certain inhaled substances.

When the airways react, the muscles around them tighten. This narrows the airways, causing less air to flow into the lungs. The swelling also can worsen, making the airways even narrower. Cells in the airways might make more mucus than usual. Mucus is a sticky, thick liquid that can further narrow the airways.

This chain reaction can result in asthma symptoms. Symptoms can happen each time the airways are inflamed.

Sometimes asthma symptoms are mild and go away on their own or after minimal treatment with asthma medicine. Other times, symptoms continue to get worse.

When symptoms get more intense and/or more symptoms occur, you’re having an asthma attack. Asthma attacks also are called flareups or exacerbations (eg-zas-er-BA-shuns).

Treating symptoms when you first notice them is important. This will help prevent the symptoms from worsening and causing a severe asthma attack. Severe asthma attacks may require emergency care, and they can be fatal.


Asthma has no cure. Even when you feel fine, you still have the disease and it can flare up at any time.

However, with today’s knowledge and treatments, most people who have asthma are able to manage the disease. They have few, if any, symptoms. They can live normal, active lives and sleep through the night without interruption from asthma.

If you have asthma, you can take an active role in managing the disease. For successful, thorough, and ongoing treatment, build strong partnerships with your doctor and other health care providers.

Family ENT, Allergy & Asthma Center Can Help You Keep Asthma Under Control

There are many triggers that can produce symptoms of asthma and lead to rapid worsening of breathing. Triggers may include pollen, animal dander, dust mites, mold, chemical exposure, smoke, and viruses. Common symptoms of asthma include breathlessness, wheezing, coughing, and chest tightness. To diagnose asthma our allergists will look at your health history and conduct an in-office pulmonary function testing. They also perform an innovative test called Exhaled Nitric Oxide (eNO) measurement, which helps determine the amount of lung inflammation.

Once we diagnose your asthma, an individualized treatment plan will be developed to help get you on the road to good health right away. Regardless of which of these treatments you receive, controlling your asthma is an attainable goal. Some of the methods our clinicians use are:

  • Preventive measures
  • Trigger avoidance
  • Activity and lifestyle modification
  • Allergy shots (immunotherapy)
  • Solutions for other conditions
  • With their advanced training in allergy, asthma, immune disorders, and pediatrics our physicians are naturally well-suited to diagnose and treat a variety of conditions including:
  • Sinus problems/nasal congestion/postnasal drip
  • Sinus headaches
  • Recurrent Ear infections
  • Chronic cough
  • Croup (barking cough)
  • Gastroesophageal reflux disease (GERD)

Since the respiratory tract is “one system,” any disease or condition affecting the nose and sinuses can also affect the larynx, trachea and lungs, and vice versa.

Family Allergy Care

Our goal is to deliver compassionate cutting-edge allergy care for the whole family. After conducting a comprehensive health history and exam, we will develop a personalized treatment plan designed to give you the freedom you seek from your condition.
