Symptoms of COPD often don't appear until significant lung damage has occurred, and they usually worsen over time, particularly if smoking exposure continues. For chronic bronchitis, the main symptom is a daily cough and sputum production at least three months a year for two consecutive years.

Other signs and symptoms of COPD include:

  • Shortness of breath, especially during physical activities
  • Wheezing
  • Chest tightness
  • Having to clear your throat first thing in the morning, due to excess mucus in your lungs
  • A chronic cough that produces sputum that may be clear, white, yellow or greenish
  • Blueness of the lips or fingernail beds (cyanosis)
  • Frequent respiratory infections
  • Lack of energy
  • Unintended weight loss (in later stages)

People with COPD are also likely to experience episodes called exacerbations, during which their symptoms become worse than usual day-to-day variation and persist for at least several days.
