Asthma and COPD both make it harder to move air out of the lungs, and both cause cough, wheeze, and breathlessness. They are frequently confused, including by patients who have been treated for one for years while actually having the other, or both. Getting the distinction right matters, because the treatments, the triggers, and the long-term outlook are different.
Elon Health Primary Care in Davenport, FL manages both conditions as ongoing care: confirming the diagnosis properly, getting the inhalers right, keeping vaccinations current, and catching flare-ups before they become hospital admissions.
The clinical picture usually separates them, and lung function testing confirms it.
The two can also coexist, particularly in adults who had asthma as children and later smoked. That combination needs a treatment plan that accounts for both rather than one or the other.
Neither condition should be diagnosed on symptoms alone. Spirometry, a breathing test that measures how much air you can blow out and how fast, is the objective test. In asthma it typically shows obstruction that improves substantially after a bronchodilator. In COPD it shows obstruction that persists after one.
Alongside that, we take a careful history of exposures and symptoms, examine you, and use chest X-ray and blood work where needed to rule out the conditions that imitate both, particularly heart failure, anemia, and reflux.
One point worth stating plainly: the U.S. Preventive Services Task Force recommends against screening for COPD in adults who have no symptoms, a Grade D recommendation reaffirmed in 2022. That is the strongest negative grade it issues. Spirometry is a diagnostic test for people with symptoms or significant exposure, not a screening test for everyone.
Modern asthma care is built around controlling inflammation rather than only relieving symptoms. Relying on a rescue inhaler several times a week is a signal that the underlying inflammation is not controlled, not a sign the inhaler is working well.
COPD treatment aims to reduce symptoms, improve what you can do in a day, and prevent exacerbations, which is where most of the harm sits.
A large share of people using inhalers do not get the medication into their lungs, because the technique is wrong or the device does not suit them. This is one of the most common reasons an inhaler seems not to work. We check technique in the room, watching you use your own device, and change the device if it is not right for you. It takes two minutes and is often worth more than adding another medication.
Respiratory infections are the usual trigger for asthma attacks and COPD exacerbations, so keeping vaccines current is genuinely disease-modifying for these patients. Under the CDC and ACIP adult immunization schedule current in 2026, that generally means an annual influenza vaccine, a COVID-19 vaccine decision made with your doctor (since October 2025 the CDC schedule treats COVID-19 vaccination as an individual, shared decision rather than a blanket recommendation), a pneumococcal conjugate vaccine (ACIP lowered the age-based recommendation to 50 and older in October 2024), and RSV vaccination for adults 75 and older or adults 50 to 74 at increased risk, a group that includes people with chronic lung disease. See immunizations and the adult vaccine schedule.
Call 911 or go to the nearest emergency department for severe breathlessness, difficulty speaking a full sentence, blue or grey lips or fingertips, confusion or drowsiness, or a rescue inhaler that is not working. Do not wait for an appointment for any of those.
Contact the office promptly, rather than waiting for a routine visit, if you are using your rescue inhaler more than usual, waking at night with symptoms, coughing up more or discoloured sputum, or finding your usual walk suddenly harder. Caught early, most flare-ups are managed at home. See also respiratory care and when to see a doctor versus wait.

Frequently Asked Questions
Asthma usually starts younger, comes and goes with identifiable triggers, and the airway narrowing largely reverses with a bronchodilator. COPD usually appears after 40 following years of exposure, most often to cigarette smoke, is persistent rather than episodic, gets gradually worse, and only partly reverses. Spirometry is the test that separates them, and some people have both.
Yes. Neither asthma nor COPD should be diagnosed on symptoms alone, because heart failure, anemia, reflux, and anxiety can all cause similar breathlessness. Spirometry measures how much air you can blow out and how fast, before and after a bronchodilator, and is the objective basis for the diagnosis.
The U.S. Preventive Services Task Force recommends against screening for COPD in adults without symptoms, a Grade D recommendation reaffirmed in 2022, because screening asymptomatic people has not been shown to improve outcomes. If you have a cough, sputum, wheeze, or breathlessness on exertion, that is a different situation and testing is appropriate.
The most common reason is technique. A large share of people using inhalers do not get the medication into the lungs, because of how they breathe in, the timing, or a device that does not suit them. We watch you use your own inhaler and correct the technique or change the device. The second most common reason is relying on a rescue inhaler when the underlying inflammation needs a regular controller.
Respiratory infections are the usual trigger for attacks and exacerbations, so vaccination is one of the most effective preventive steps available. Under the CDC schedule current in 2026 that generally means annual influenza vaccination, a COVID-19 vaccine decision made with your doctor, which the CDC schedule has treated as an individual, shared decision since October 2025, pneumococcal vaccination (recommended from age 50 since ACIP lowered the threshold in October 2024), and RSV vaccination for adults 75 and older or 50 to 74 at increased risk, which includes chronic lung disease.
