Have you had 2 or more respiratory infections in the past 12 months? Could it be bronchiectasis?

Bronchiectasis can be tricky and often goes undiagnosed or misdiagnosed for quite some time. It’s important to understand how COPD can contribute to bronchiectasis and why catching it early can make a big difference. Let’s take a closer look together!

Understanding Bronchiectasis and COPD Overlap Syndrome (BCOS)

This blog post was authored by Alyssa Dittner, BS, RRT, and reviewed by the Bronchiectasis and NTM Content Review and Evaluation Committee

Have you heard of bronchiectasis and chronic obstructive pulmonary disease (COPD) overlap syndrome (BCOS)? This condition happens when someone has both bronchiectasis and COPD.¹ Bronchiectasis is a lung disease where the airways get wider and scarred, making it hard for mucus to clear out.² This can lead to frequent lung infections. COPD is a different lung disease that makes breathing difficult because airways become blocked and the lungs lose elasticity that helps air move in and out.⁵ Although they are different diseases, they can show similar symptoms.

Common Symptoms of BCOS Include:¹

• Frequent lung infections
• Daily cough
• Shortness of breath
• Mucus production
• Feeling tired
• Weight loss

Because COPD and bronchiectasis can share similar symptoms, some people may take 12 to 17 years to get the right diagnosis.³ COPD can be caused by breathing in irritants like tobacco smoke, pollution, and chemicals.⁶ But bronchiectasis can be caused by things outside a person’s control, like frequent lung infections, autoimmune diseases (such as Rheumatoid arthritis and Sjogren’s syndrome), and conditions like gastroesophageal reflux disease (GERD), which causes stomach acid to flow back into the lungs.⁶ However, in about 40% of cases, the cause is unknown.⁷

Research shows that BCOS is not fully understood, with diagnosis rates ranging from 4% to 72%.³ High-resolution CT scans are helping health care providers find bronchiectasis more often in people with COPD.²

COPD Does Not Mean You Will Get Bronchiectasis, But You Could Have a Higher Risk

More research is needed to understand the link between the two conditions.³ While COPD can make the lungs more sensitive and lead to inflammation (swelling in the airways) from irritants, this can cause the airways to narrow and produce more mucus.³ Over time, this can lead to lung infections and scarring, which might increase the risk of bronchiectasis.⁴

Early Detection Matters

Identifying bronchiectasis early is important to help slow down lung damage.³ If you produce mucus daily, have a constant cough, feel tired, or experience shortness of breath, talk to your health care provider about the possibility of being tested for bronchiectasis.

Tests Your Health Care Provider Might Recommend

Your health care provider may suggest several tests including:²

• Chest CT scan: Painless test that takes detailed pictures of your lungs.
• Sputum culture: A collection of mucus to look for bacteria or fungi.
• Pulmonary function test: Breathing test that’s checks how well your lungs are working.

While there is no cure for bronchiectasis, it can be managed.² Treatment focuses on treating underlying conditions, managing lung infections, using airway clearance techniques, inhaled medications, and mucus thinners.⁷
