Living with sleep apnea already makes breathing at night difficult. But when chronic obstructive pulmonary disease (COPD) is also part of the picture, the challenges can grow much more serious.

Many people do not realize that it is possible to have sleep apnea and COPD at the same time, and this combination has a name: overlap syndrome.

Understanding how sleep apnea and COPD interact can help you spot symptoms sooner and get treatment that protects your health.

Can You Have Both Sleep Apnea and COPD?

The short answer is yes. This combination is referred to as overlap syndrome, and it describes people who have both obstructive sleep apnea (OSA) and COPD at the same time.

COPD is a condition where lung damage causes long‑term airflow blockage, while OSA creates repeated airway collapse while you sleep.

COPD and OSA are both relatively common on their own. Their coexistence creates unique challenges because both conditions affect how well the body gets oxygen.

When someone has overlap syndrome, the breathing issues from one condition may worsen the other. COPD causes chronic inflammation and narrowed airways, while OSA causes repeated pauses in breathing during sleep.

Together, sleep apnea and COPD can lead to symptoms like lower oxygen levels, trouble sleeping, breathing problems throughout the night, and more daytime fatigue.

Does Having One Condition Increase the Risk of the Other?

While research on the relationship between COPD and OSA is relatively limited, some evidence suggests that having OSA may raise the risk of developing COPD, while changes in OSA severity may also affect COPD risk.

One study from 2025 found that adults with high baseline OSA risk were more likely to develop COPD over time. The study also noted that people whose OSA risk decreased over time had a lower chance of developing COPD.

This means that managing sleep apnea may not only improve sleep and daytime alertness, it could also help reduce your long-term risk of worsening lung disease.

If you smoke, have obesity, or live with a heart condition, you may be at a higher risk of developing overlap syndrome.

How Common Is It To Have Both Conditions?

Overlap syndrome may be more widespread than many people realize, though exact numbers vary depending on the population being studied.

In the general population, overlap syndrome affects roughly 1 percent of people, but some research suggests that the true prevalence could be even higher, as the condition is often under-recognized and there aren’t clear guidelines for diagnosis.

Another study found that the prevalence rate of COPD and OSA may be as high as 66 percent.

How Does Having Sleep Apnea and COPD Affect Symptoms and Health?

When COPD and sleep apnea occur together, their effects can add up and become more severe than either condition alone.

In addition to symptoms like poor sleep quality, increased daytime fatigue, and trouble breathing at night, studies show that overlap syndrome may also lead to:

• Worse oxygen levels at night — People with both conditions tend to have more severe nighttime drops in blood oxygen levels, which can increase strain on the heart and cause other complications.
• Greater inflammation and stress — The combination of chronic lung blockage and repeated nighttime breathing pauses can cause damage to your body’s tissues and cells. This can raise the risk of problems such as pulmonary hypertension, arrhythmias, and right-sided heart failure.
• More hospital visits — Those with overlap syndrome have more frequent COPD flare-ups and are more likely to need hospital care.
• Longer and complicated hospital stays — Compared to individuals with COPD flare-ups, those who also had OSA had longer hospital stays, higher costs of care, and more need for ventilation.

Signs You Might Have Both Sleep Apnea and COPD

Because symptoms can overlap with many other health problems, recognizing overlap syndrome can sometimes be tricky. You may notice signs from each condition, but sometimes they blend together.

Some common sleep apnea symptoms include:

• Loud snoring
• Breathing pauses while sleep
• Choking or gasping that wakes you up
• Morning headaches
• Daytime sleepiness

COPD may cause symptoms such as:

• Shortness of breath, especially during activity
• Trouble taking deep breaths
• Chronic cough with mucus
• Wheezing
• Frequent respiratory infections
• Chest tightness

If you currently have OSA or COPD, you may suspect overlap syndrome if you notice additional symptoms like:

• Cyanosis (bluish or graying tint to the skin, fingernails, or lips), which may be more or less visible depending on skin tone
• Chest pain or pressure
• Dizziness or fainting
• Rapid or pounding heartbeat
• Fatigue or feeling sluggish throughout the day
• Swelling in the ankles, legs, or abdomen
• Headaches
• Confusion or disorientation
• Depression
• Seizures

These symptoms may be signs of high blood pressure in the lungs (pulmonary hypertension) and low levels of oxygen (hypoxemia) or high levels of carbon dioxide (hypercapnia) in the blood.

With overlap syndrome, individuals are at an increased risk of developing these conditions.

If you think you might have overlap syndrome, discuss your symptoms with your healthcare team. Early diagnosis and treatment measures can lead to a better quality of life and a reduced risk of complications.

How Are Sleep Apnea and COPD Managed Together?

Managing overlap syndrome requires treating both COPD and OSA at the same time. The good news is that effective treatments exist, and treating one condition can often improve the other.

Treating COPD

Your doctor may have you try a variety of COPD treatments, which include:

• Medications like steroids or bronchodilators that open up your airways by reducing inflammation
• Pulmonary rehabilitation education and exercise programs used to improve lung strength
• Oxygen therapy for supplemental oxygen that helps you breathe
• Programs to help you quit smoking

The goal of these treatments is to open the airways, improve COPD symptoms, reduce inflammation, and improve overall lung function.

Reducing Sleep Apnea Symptoms

The main treatment for OSA is positive airway pressure therapy, or PAP therapy. The most common is continuous positive airway pressure, also known as CPAP.

CPAP keeps the airway open at night, preventing pauses in breathing. Research shows that CPAP therapy may also lower hospitalization rates and even improve survival in people with overlap syndrome.

Some other OSA treatment options include sleeping with oral appliances (mouth devices) and surgical procedures.

Making Lifestyle Changes

Making certain changes in your current lifestyle could also help reduce symptoms of both OSA and COPD. Some helpful lifestyle changes include:

• Maintaining a healthy weight
• Quitting smoking
• Staying active throughout the day
• Creating good sleep habits, like sleeping on your stomach and side instead of your back
• Reducing alcohol consumption

• Avoiding any COPD triggers, including stress, pollution, and secondhand smoke

Before making any changes to your current lifestyle, be sure to talk with your healthcare provider first. Together, you can determine the best plan for your individual needs.
