My BMI is twice what it should be and I would never think of approaching my doctor for non-urgent surgery. It would risky for me, expensive for the NHS and my cats would have to go and live with my brother if I died.
I have seen women of my size moaning in the press that they have been turned down for boob reduction operations.
The NHS is stretched as it is and it is not going to improve unless we all accept its limitations.
I have always had excellent service from my GP and his practice, my psychiatrist is approachable. I may just be lucky in that everything is much better north of the border (that was a joke).
I have excellent service from my vet too but that costs lots of money. I currently pay £50 per month in insurance for two moggies, as one is asthmatic and has an ongoing claim I can't change to another company. Maybe that is the way that the NHS may be headed in.
