New treatment allows severe asthma sufferers to breathe more easily.
Professor Pallav Shah, a consultant in respiratory medicine at Royal Brompton Hospital, is pioneering a new treatment for severe asthma sufferers called 'bronchial thermoplasty'.
Its main benefit to patients is that it can reduce or eliminate the need for steroid medication for asthma, which can lead to side effects like weight gain, depression and osteoporosis.
The procedure itself involves reducing the amount of muscle around the airways, which are known to be thicker in asthma sufferers.
