Healthwatch Kirklees calls on NHS chiefs to be honest

He added: “There is something here about the changed relationship that we need to start having with the NHS.

“When Healthwatch asked people about these ideas last year, there was really strong support for them.

“There were strong messages from respondents that said that people needed to take more responsibility for their own health, and not just expect the NHS to pick up the pieces.

“It’s another step towards a changed relationship between people and their NHS.”

Figures suggest as many as one in three of Kirklees’ adult population are set to fall foul of the new policy to be implemented later this year.

Overweight people will be given 12 months to get their BMI down below 30 to discourage patients from attempting “crash diets.”

If they lose 10% of their weight but still have a BMI above 30 they will be listed for surgery.

Smokers will have to be smoke free for four weeks prior to surgery, but will be put on a six-month stop smoking plan to help them to quit.

If they fail to give up smoking after six months they will be listed for surgery anyway.

The system is only in place for non-urgent surgery and does not apply to critical life-saving surgery or certain urgent procedures such as cancer treatment or pregnancy interventions. Children are not affected. Doctors will be allowed to break the rules if they believe it is appropriate, for example if a patient’s condition could get substantially worse by delaying surgery.
