A new surgical treatment that uses tiny electrodes to burn away nerves that causes breathlessness is being tested on patients with lung disease.
Sufferers of severe lung disease are being offered a new surgical treatment which uses tiny electrodes to burn away nerves that make them feel breathless.
The operation, which is being tested on NHS patients at the Royal Brompton and Chelsea and Westminster Hospitals in London, is the latest hope for those with COPD.
The hour-long procedure works by burning away damaged nerves, and in doing so prevents the abnormal narrowing of the airways and over-production of mucus.
In patients with COPD, nerves in the lungs become overactive, often because of damage caused by smoking. Chemical signals from these nerves prompt the airways in the lungs to contract and narrow, so patients feel very short of breath.
