What is a COPD Flare-up?
A flare-up is the worsening of COPD symptoms. They are the main reason people with COPD go to the hospital. Flare-ups should be taken very seriously. They are usually caused by a trigger such as air pollution or allergens, or a chest infection from a virus (cold or flu) or bacteria. Do your best to prevent flare-ups and treat them quickly when they occur.
How to Avoid a COPD Flare-up
Steps to Stay Healthy to Avoid Flare-ups
- Take care of yourself to avoid cold, flu and other infectious diseases.
- Take all your medications as directed.
- Eat a healthy well-balanced diet.
- Get enough sleep.
- Stay away from people who are sick. Explain to friends and family that colds and flus can cause a COPD flare-up for you. It is important they know to keep their distance when they are unwell.
