A condition which causes people to struggle with breathing while carrying out everyday activities is to be recgonised as a 'syndrome' in a bid to raise awareness.
Chronic breathlessness is sometimes referred to as dyspnoea. It often develops gradually and lasts for weeks, months or years.
Researchers at the University of Hull say that people are often embarrassed to report to doctors or nurses, or feel that the condition is their own fault.
They hope that by categorising the illness as a syndrome, people will be more inclined to seek help for the condition.
