Chronic obstructive pulmonary disease (COPD) makes breathing increasingly more difficult. But it develops slowly over many years and you may not be aware you have it at first.
Most people with COPD do not have any noticeable symptoms until they reach their late 40s or 50s.
Common symptoms of COPD include:
The symptoms will usually get gradually worse over time and make daily activities increasingly difficult, although treatment can help slow the progression.
Sometimes there may be periods when your symptoms get suddenly worse – known as a flare-up or exacerbation. It's common to have a few flare-ups a year, particularly during the winter.
Less common symptoms of COPD include:
These additional symptoms only tend to happen when COPD reaches an advanced stage.
See your GP if you have persistent symptoms of COPD, particularly if you're over 35 and smoke or used to smoke.
