The British Lung Foundation has re-directed its focus away from medical research to providing information and support for people with breathing problems.
The foundation has been running a support network, the Breathe Easy Club, for more than 10 years. But in the past four years it has seen the club's membership numbers double, which has prompted the re-focusing.
The Breathe Easy Club currently supports 20,000 people with lung conditions and the charity intends to more than double that number in the next three years. It aims to have a Breathe Easy Club support group attached to every chest clinic in the country
Dr Mark Britton, chairman of the British Lung Foundation, said: "There is a real demand for support for people who live with a lung disease - which is so often extremely debilitating and isolating. This new strategy will mean that we can plan to expand to meet that demand."
A major volunteer recruitment drive will take place later this year.
