When to See a Doctor
🚨 Seek care urgentlySee a doctor if you have a persistent cough with phlegm, or are short of breath doing things that used to be easy. Call 911 for: sudden severe breathing difficulty, blue lips, confusion, or inability to speak due to breathlessness.
Early Warning Signs
2 symptomsChronic productive cough
A long-standing cough that produces mucus (sputum) — particularly in the morning. Often dismissed as a "smoker's cough" but is an early COPD warning sign.
Shortness of breath with exertion
Initially only with vigorous activity, but progressively worsening to breathlessness with mild activity or even at rest as COPD advances.
Common Symptoms
1 symptomWheezing
A high-pitched whistling sound when breathing out, caused by narrowed airways obstructed by mucus and inflammation.
Advanced Symptoms
3 symptomsFrequent respiratory infections
Damaged airways are more susceptible to bacterial and viral infections, and each exacerbation can permanently accelerate lung function decline.
Barrel chest appearance
Air trapped in over-inflated lungs causes the chest to appear rounded and barrel-shaped. Sign of advanced emphysema.
Unexplained weight loss
The work of breathing with severe COPD burns enormous calories. Weight loss despite normal eating is a sign of advanced disease.

1 symptomCyanosis (blue lips or fingertips)
Blue discoloration from severely low oxygen levels. Requires emergency oxygen therapy immediately — call 911.
