When Two Conditions Meet

Chronic Obstructive Pulmonary Disease (COPD) and Obstructive Sleep Apnoea (OSA) are both common respiratory conditions.

When a patient has both conditions together, it is known as “Overlap Syndrome.”

Why Is It Important?

COPD affects breathing during the day, while sleep apnoea affects breathing during sleep.

Together they may contribute to:

• Lower oxygen levels
• Poor sleep quality
• Increased cardiac strain
• Greater fatigue

Common Symptoms

Patients may experience:

• Snoring
• Breathlessness
• Poor sleep quality
• Morning headaches
• Excessive tiredness

The Importance of Investigation

Patients with COPD who experience ongoing fatigue or poor sleep should discuss whether sleep testing may be appropriate.

Key Message

Understanding both daytime and overnight breathing is important for achieving the best possible respiratory health.
