A BBC doctor has issued a warning after encountering two patients this week whose persistent coughs were linked to a serious, incurable lung condition. Dr Punam Krishan, speaking on BBC Morning Live, shared crucial insights into chronic obstructive pulmonary disease (COPD), a progressive illness affecting around 1.7 million people in the UK—many of whom remain undiagnosed.
Addressing concerns raised by presenter Nick Knowles about misleading online claims that COPD can be cured within one to two weeks, Dr Krishan urged the public to be cautious about misinformation. She stressed the importance of seeking advice from trusted medical sources, such as the NHS or healthcare professionals, before trying unproven treatments.
“COPD is a progressive lung condition that worsens over time, and unfortunately, there is no quick cure,” Dr Krishan explained. “Symptoms often develop slowly and are frequently mistaken for normal aging or lack of fitness, causing many to delay seeking help.” She emphasized that early diagnosis is essential for managing symptoms effectively.

Smoking is a leading cause of COPD, which primarily involves emphysema and chronic bronchitis. These conditions cause lung inflammation, airway narrowing, and damage to the tiny air sacs responsible for oxygen exchange, leading to long-term breathing difficulties.
Dr Krishan urged anyone experiencing a cough lasting more than four to six weeks without a clear cause to consult a doctor. “Many people ignore persistent coughs, but getting diagnosed early can improve symptom management and quality of life,” she said.
With spring approaching, hay fever is another factor that can exacerbate respiratory issues, especially for those with COPD. “Around a quarter of people with COPD are sensitive to pollen, which can trigger flare-ups or mimic infections,” Dr Krishan noted. She encouraged people to monitor their symptoms closely, especially if they notice increased coughing, phlegm production, or congestion.
In summary, persistent coughs should never be dismissed lightly. Early medical evaluation could be crucial in identifying chronic lung disease and starting appropriate care.
