Asthma is a chronic disease affecting more than 25 million people in the United States. Patients suffering from asthma feel shortness of breath, chest tightness and experience coughing and wheezing. Asthma symptoms are due to inflammation and spasms of the lungs’ airways and can be triggered by infections, exercise, allergens, strong smells, and cold air. There is no cure for asthma, but there are many effective treatments. For decades, asthma treatment has been focused on the complications of asthma, including inflammation, as well as relief of acute symptoms. Common medications include inhaled steroids, leukotriene antagonists and bronchodilators. However, despite wide use of these medications, many patients still experience continued symptoms and uncontrolled asthma. Fortunately, new therapies are now available which target specific root causes of asthma, not just the effects. These therapies are called biologics.

When asthma doesn't respond to consistent treatment, it's considered severe asthma. Watch this video for more severe asthma facts.
