During a checkup, the doctor will ask if you cough a lot, especially at night, and whether your breathing problems are worse after physical activity or at certain times of year. The doctor will also ask about chest tightness, wheezing, and colds lasting more than 10 days. They will ask whether anyone in your family has or has had asthma, allergies, or other breathing problems, and they will ask questions about your home. The doctor will also ask if you have missed school or work and about any trouble you may have doing certain things.
The doctor will also do a breathing test, called spirometry, to find out how well your lungs are working. The doctor will use a computer with a mouthpiece to test how much air you can breathe out after taking a very deep breath. The spirometer can measure airflow before and after you use asthma medicine.
