What Causes COPD to Flare-Up?
Published: Sep 25, 2023
COPD flare-ups often leave patients struggling with worsened symptoms. Understanding the causes of these exacerbations is crucial for managing the condition effectively.
The Main Culprit: Infections
Respiratory infections are behind most COPD exacerbations, with viruses and bacteria playing the lead roles. While viruses like rhinoviruses and influenza are frequent offenders, bacteria such as Haemophilus influenzae also contribute significantly. Interestingly, the pandemic highlighted how measures like masking reduced viral infections, impacting COPD hospitalizations.
Other Triggers: Beyond Infections
Besides infections, factors like environmental pollution, eosinophilic inflammation, and medication non-compliance can trigger COPD exacerbations. Pollution and new bacterial strains often lead to increased airway inflammation, while skipping medications can destabilize the condition. Understanding these triggers is vital for prevention.
Coinfections: A Double Trouble
Coinfections involving both viruses and bacteria can worsen COPD exacerbations. Studies show such scenarios lead to more severe symptoms, longer hospital stays, and a greater drop in lung function. Addressing both pathogens during treatment is crucial for better outcomes.
