Dr Punam Krishan, a BBC medical expert, has issued a strong warning after encountering two patients this week with a persistent cough that turned out to be chronic obstructive pulmonary disease (COPD), an incurable lung condition affecting an estimated 1.7 million people in the UK.
Speaking on BBC Morning Live, Dr Krishan emphasized the importance of not dismissing a prolonged cough. Addressing misconceptions, she highlighted that COPD is a progressive disease that worsens over time and cannot be cured within days or weeks, despite misleading online claims suggesting rapid remedies.
Presenter Nick Knowles referenced a viewer’s question about whether COPD symptoms can resolve within 7 to 14 days. Dr Krishan clarified that COPD involves chronic inflammation, airway narrowing, and lung tissue damage, making quick recovery impossible. Smoking remains the most common cause, although symptoms often develop slowly and are frequently mistaken for aging or fitness issues.

“With COPD, early diagnosis is crucial,” Dr Krishan explained. “If you have a new cough lasting more than four weeks, especially if it’s unexplained, you should consult a healthcare professional. Early intervention can help manage symptoms effectively.”
She also addressed how seasonal allergens like pollen can aggravate COPD, as roughly one in four people with the disease are sensitive to pollen. This sensitivity can worsen symptoms, such as increased coughing and phlegm production, which might be mistaken for infections or flares.
Dr Krishan urged the public to rely on trusted medical sources, like the NHS website, and to avoid unproven treatments promoted on social media. She underscored the importance of medical advice from healthcare providers to properly diagnose and manage lung conditions.
In summary, a cough persisting beyond four weeks should not be ignored. Timely evaluation can identify underlying causes, including COPD, and improve quality of life through appropriate management.
