What is asthma?

Asthma is a lung disease that makes breathing difficult. Chronic inflammation and reactions to triggers narrow the airways in the lungs. Asthma can become life-threatening if it is not managed.

What is cough-variant asthma?

Cough-variant asthma is a type of asthma that causes a dry cough that keeps coming back. A dry cough may be your only symptom, or you may also have chest tightness. These symptoms may be caused by exercise or exposure to odors, allergens, or respiratory tract infections. Cough-variant asthma is treated the same way as typical asthma.

How is asthma diagnosed?

Your healthcare provider will examine you and listen to your lungs. He or she will ask how often you have symptoms and what makes them worse. Tell him or her if you have trouble sleeping, exercising, or doing other activities because of shortness of breath. Your provider will ask about your allergies and past colds, and if anyone in your family has allergies or asthma. Tell your healthcare provider about medicines you take, including over-the-counter drugs and herbal supplements. You may need a chest x-ray to check for lung problems, or a lung function test. Lung function tests show how well you can breathe.
