Steve Bowen, a retired police officer, knew something was gravely amiss when a routine walk to pick up his grandson Riggs from school left him gasping for air. His head throbbed, and he found himself needing frequent breaks just to catch his breath.

“My grandson kept urging me to pause and rest,” Steve, now 71, recalls. “I genuinely feared for my life—I simply couldn’t breathe.”

Initially, these alarming symptoms seemed to appear out of the blue. However, Steve later realized that his energy levels and lung capacity had been gradually declining over the years, an issue that had gone unnoticed until this wake-up call.

Following medical consultations, Steve was diagnosed with chronic obstructive pulmonary disease (COPD), a progressive lung condition. By this stage, even climbing a flight of stairs had become an uphill battle.

In the UK, COPD impacts approximately 1.7 million individuals. Alarmingly, the charity Asthma + Lung reports that about 600,000 people are living with the condition without a diagnosis.

Tragically, COPD claims the lives of around 30,000 Britons annually. It can lead to organ failure and significantly increases the risk of fatal lung infections. Research indicates that most patients have a life expectancy of fewer than ten years following their diagnosis.

Steve, from Essex, says: ‘What was scary was that no one told me how long I would have, and I feared I wouldn’t see my grandchildren grow up.’

However, the grandfather of four, who was a smoker for decades, explains his diagnosis gave him a new motivation. ‘I had given up smoking about ten months before I was diagnosed but I knew I couldn’t let it beat me,’ he says. ‘My youngest grandson was three, and I gave myself the target of reaching his tenth birthday.’

Steve was given prescription inhalers – drugs that can open up the airways making it easier to breath. Yet following his own research he also committed himself to an ambitious exercise routine and diet.

He would walk six miles a day, attend the gym twice a week and eat just 1,500 calories a day – half the average.

Steve admits at the beginning these changes were challenging, and says: ‘I struggled with walking, and it took me about six months to get to a slow jog.’

Yet he persevered. After three months he had lost two-and-a-half stone – and the improvements did not stop there.

After a few more months of training, Steve joined a running club and, four years on from his diagnosis, he fulfilled a remarkable achievement – he completed last year’s London Marathon.

While Steve’s recovery is particularly astounding, experts claim the majority of COPD patients can improve their symptoms with similar steps.

Dr Nick Hopkinson, medical director at Asthma + Lung UK, says: ‘Patients can make a difference to their condition through lifestyle changes. We do have effective medicines but these are best used in combination with these changes everyone can do.’

COPD is primarily caused by exposure to irritants such as cigarette smoke and air pollution that damage the air sacs – alveoli – in the lungs that allow oxygen to enter the bloodstream. It can also inflame the airways, making it difficult for air to enter the lungs.

The first symptoms are a persistent cough, excessive mucus production and shortness of breath, which can disrupt sleep. These issues gradually worsen until they become life-threatening.

However, lifestyle changes can reverse this decline.

A 2024 review found that patients who started exercise programmes within three weeks of being in hospital were half as likely to be readmitted later on.

While exercise cannot reverse the damage to the lungs, it can help strengthen the remaining healthy tissue, improving patients’ breathing and quality of life.

Professor Russell, an expert in respiratory medicine at King’s College London, says: ‘Patients are often scared of exercise when they have COPD, because being breathless triggers a fear response in the brain. But exercising will improve quality of life and can prolong length of life.’

He recommends increasing walking distance and lifting light weights. Diet changes can also make a big difference – one low in salt and high in fruit and vegetables can improve lung function.

Crucially, experts say people with breathing difficulties should not wait for a COPD diagnosis before they make these changes.

Interestingly, they also insist that managing the anxiety and depression that often comes following a COPD diagnosis is really important for reducing symptoms.

Yoga, breathing workshops and choir singing are recommended.

Five years on from his diagnosis, Steve is doing well and his lung function has improved.

‘I am feeling so much better now,’ he says.

‘My youngest grandson is eight, and when he gets to ten I will set a new target – I am determined to keep going.’
