Chronic obstructive pulmonary disease (COPD) is a group of lung diseases that makes it harder for you to breathe.1 With COPD, your airways may be inflamed, narrowed or damaged, limiting airflow in and out of your lungs. The two most common forms are chronic bronchitis and emphysema. COPD is often diagnosed in adults over age 65 and is strongly linked to long-term exposure to lung irritants, especially cigarette smoke.

What Are the Symptoms of COPD?

COPD symptoms often start slowly and may be mistaken for normal aging at first. Over time, symptoms become more noticeable and can interfere with your daily routine.

Common COPD symptoms include:

  • Shortness of breath, especially during physical activity
  • Chronic cough that may produce mucus
  • Wheezing or chest tightness
  • Frequent respiratory infections
  • Fatigue or low energy
  • Difficulty taking deep breaths

If your symptoms suddenly worsen or “flare up,” it may be a COPD exacerbation, and you should contact your provider.2

Types of COPD

There are different types of COPD. Many people have a combination. Each type affects your lungs differently.

Types of COPD
Type of COPD Description
Chronic bronchitis Ongoing inflammation of the airways that leads to a daily cough and mucus production
Emphysema Damage to the air sacs (alveoli), reducing oxygen exchange and causing breathlessness
Asthma-COPD overlap (ACO)3 Features of both asthma and COPD often requiring tailored treatment
Refractory (advanced) COPD Severe disease that does not respond well to standard therapies

Stages of COPD

COPD stages describe the severity of the condition.4 Your provider may use breathing tests, symptoms and flare-up history to determine your stage and help guide treatment.

  • Stage 1 (mild): Symptoms are minimal; airflow limitation is mild.
  • Stage 2 (moderate): Shortness of breath becomes more noticeable during activity.
  • Stage 3 (severe): Frequent symptoms and reduced ability to exercise.
  • Stage 4 (very severe): Serious breathing difficulty and reduced quality of life.

Your provider may also group your risk for exacerbations using letters:

  • Group A: Low symptoms, low risk
  • Group B: More symptoms, low risk
  • Group E: High risk of exacerbations5

What Are the COPD Risk Factors?

COPD risk factors are things that increase your chances of developing the condition. Having one risk factor does not mean you will get COPD, but it does mean you should pay attention to symptoms.

Common COPD risk factors include:

  • Current or former smoking
  • Long-term exposure to secondhand smoke
  • Air pollution or occupational dust and chemicals
  • History of childhood lung infections
  • Older age
  • Genetic factors, including rare conditions affecting lung health

Avoiding lung irritants and quitting smoking can help slow COPD progression.6

How Is COPD Diagnosed?

If you are wondering how COPD is diagnosed, it often starts with your primary care provider (PCP). Your PCP will review your symptoms, medical history and risk factors. If COPD is suspected, your provider may order initial testing and refer you to a pulmonologist for confirmation.

COPD diagnosis often includes:

  • Spirometry: A breathing test that measures lung function
  • Chest imaging: X-ray or CT scan
  • Oxygen testing: A check of oxygen levels in your blood

Early COPD testing helps confirm the cause of your symptoms and can help prevent complications.7

COPD Management and Treatment

COPD has no cure, but treatment can help you breathe easier, stay active and reduce flare-ups. Your care plan will depend on your symptoms and your stage.8

Common COPD treatment options include:

  • COPD inhalers to open the airways and reduce inflammation
  • COPD medications, such as bronchodilators or steroidsv
  • Pulmonary rehabilitation and guided exercise
  • Oxygen therapy, if needed
  • Lifestyle changes, including smoking cessation and vaccinations

Your care team can help you find the right mix of treatments and support for your day-to-day life.

Frequently Asked Questions About COPD

COPD is most often caused by long-term exposure to lung irritants, especially smoking. Genetics can also play a role. A rare inherited condition called alpha-1 antitrypsin deficiency can increase COPD risk, even if you never smoked.9 If you have a strong family history of lung disease, ask your provider whether genetic testing or earlier screening makes sense for you.

You cannot fully test yourself for COPD at home. However, symptom checklists and peak flow readings may raise early concerns. If you have an ongoing cough, shortness of breath, wheezing or frequent respiratory infections, especially with a smoking history, schedule a visit with your PCP. A breathing test called spirometry is needed to confirm COPD and rule out other conditions.

A COPD exacerbation is a sudden worsening of symptoms such as shortness of breath, coughing or increased mucus. Common triggers include respiratory infections and air pollution. Exacerbations may require medication changes, urgent care or hospitalization. They can also speed up COPD progression, so it is important to contact your provider quickly if symptoms flare up.

Taking Care of Yourself with COPD

Staying active and exercising safely

Being active is one of the most important things you can do to protect your lungs, keep up your strength, and stay independent when you have COPD. Even a few minutes of movement spread throughout the day can help you breathe easier, have more energy, and feel less stressed.10, 11, 12

Try to include three kinds of activity most days of the week:11, 12

  • Aerobic exercise (for your heart and lungs):

    • Examples: walking on level ground, slow cycling on a stationary bike, or light swimming.
    • Goal: Work toward about 20–30 minutes, 3–4 days per week, which you can break into 5–10 minute blocks with rest in between.12, 11
    • You should feel “a little short of breath but able to talk in full sentences.” If you cannot speak in full sentences, slow down or rest.
  • Strength exercises (for your arms and legs):

    • 2–3 days per week, do simple exercises like:

      • Sit-to-stand from a sturdy chair
      • Wall push‑ups
      • Lifting light hand weights or resistance bands for your arms13, 11
    • Aim for 1–2 sets of 8–12 repetitions, resting as needed. Stronger muscles help you walk farther and do daily tasks with less breathlessness.14, 11
  • Flexibility and breathing exercises:

    • Gentle stretching of your shoulders, chest, back, and legs before and after exercise helps you move more easily and warms up your body.11, 12
    • Practice pursed‑lip breathing (inhale through your nose for 2 counts, exhale slowly through pursed lips for 4 counts) and diaphragmatic breathing to help control shortness of breath during activity.11

Practical tips:15, 12, 11

  • Use your rescue inhaler as directed by your provider before activity if recommended.
  • Avoid exercising outdoors in extreme heat, cold, or on days with poor air quality.
  • Stop and rest right away if you feel chest pain, dizziness, severe shortness of breath, or if your symptoms feel different than usual, and follow your action plan.
  • If you have heart disease or other health conditions, talk with your provider before starting or changing your exercise routine.15

How to recognize a COPD exacerbation

A COPD exacerbation (also called a flare‑up) is when your breathing symptoms suddenly get worse and do not improve with your usual medications. Recognizing early warning signs and acting quickly can prevent a hospital stay and protect your lungs.16, 17, 18

Call your clinic promptly if you notice any of these changes:17, 18, 16

  • More shortness of breath than usual, especially at rest or with light activity.
  • Needing your rescue inhaler more often than usual.
  • New or worse wheezing or chest tightness.
  • More coughing than usual or coughing that keeps you from sleeping.
  • Increased mucus (phlegm) — more than usual, or it becomes thicker, stickier, or changes color (yellow, green, brown, or bloody).
  • New or worse swelling in your ankles or legs.
  • Feeling much more tired or having trouble doing your normal activities.

Call 911 or go to the emergency room right away if:18, 17

  • You are struggling to catch your breath or cannot speak in full sentences.
  • Your lips or fingertips look blue or gray.
  • You feel confused, very drowsy, or suddenly cannot think clearly.
  • You have severe chest pain, or your usual oxygen level (if you monitor it) suddenly drops and does not improve with your usual treatments.

Having an exacerbation (flare-up) plan

Every person with COPD should have a written plan for what to do when symptoms flare so you and your care team can act quickly. This plan helps you know which medicines to take, when to call your doctor, and when to seek emergency care.19, 16, 17

Ask your doctor or clinic to help you create a simple COPD action plan that includes:16, 17

  • Your “everyday” plan

    • The names and doses of your regular inhalers and medications.
    • When and how to use your rescue inhaler or nebulizer.
  • Your “yellow zone” (worsening symptoms) plan

    • Clear instructions for what to do when you first notice more shortness of breath, cough, or mucus.
    • If appropriate, a “rescue pack” at home (for example, a short course of steroid pills and/or an antibiotic) with written instructions on when to start them and when to call the clinic first.
    • How often to use your rescue inhaler or nebulizer during a flare‑up.
  • Your “red zone” (emergency) plan

    • A list of symptoms that mean you should call 911 or go straight to the emergency room.
    • Your current medication list and any allergies, kept in a wallet card or on your phone so emergency teams can see it.

To start the conversation with your doctor, you might say:

  • “I’d like a written COPD action plan so I know what to do if my breathing gets worse.”
  • “Can we review when I should call the clinic, when to start extra medicines at home, and when I should go to the ER?”
  • “These are the flare‑ups I’ve had in the past year — can we talk about how to prevent them and what to do earlier next time?”

Bring this plan (or a photo of it on your phone) to every visit and to the emergency room if you ever need to go and ask your care team to review and update it at least once a year or after any hospitalization.19, 17, 16
