Shortness of breath is usually the first sign of COPD. It may worsen over time, especially during physical activity. Additional symptoms that may worsen over time include a persistent, productive cough; wheezing, squeaking, or whistling while breathing; and tightness in the chest.
A sudden aggravation of symptoms is called an exacerbation. Signs of an exacerbation include worsening:
- Cough
- Shortness of breath
- Fatigue
- Difficulty sleeping
- Confusion
- Headaches
- Pulse oximeter readings (blood oxygen levels)
Medications and breathing exercises can help during an exacerbation. You should always contact your doctor if your symptoms are getting worse. There are many therapies to get you back on track and feeling better.
