Don't treat the old and unhealthy, say doctors in Britain:
Smokers, heavy drinkers, the obese and the elderly should be barred from receiving some operations, according to doctors, with most saying the health service cannot afford to provide free care to everyone.
Obesity costs the British taxpayer £7 billion a year. Overweight people are more likely to contract diabetes, cancer and heart disease, and to require replacement joints or stomach-stapling operations.
Meanwhile, £1.7 billion is spent treating diseases caused by smoking, such as lung cancer, bronchitis and emphysema, with a similar sum spent by the NHS on alcohol problems. Cases of cirrhosis have tripled over the past decade.
Among the survey of 870 family and hospital doctors, almost 60 per cent said the NHS could not provide full healthcare to everyone and that some individuals should pay for services.
One in three said that elderly patients should not be given free treatment if it were unlikely to do them good for long. Half thought that smokers should be denied a heart bypass, while a quarter believed that the obese should be denied hip replacements.
