What a person actually weighs isn't necessarily an indicator of whether or not they're over weight, nor is their BMI.
I'm in my mid 50's, have been on HRT since my early 30's which increases bone density hence it's positive effect on osteoporosis. I attend a gym 3 to 4 times a week and have done so for several years, regularly lifting weights which increases my muscle mass; muscle weighs more than fat.
People are often surprised when they know how much I weigh, expecting it to be less because I don't look over weight yet, if I were to do my BMI I would most certainly come out as weighing more than I should.
I smoke on average 10 to 12 cigarettes a day, haven't been to the doctors for years (apart from getting sleeping pills due to Mr. S.'s snoring) and enjoy more than the occasional glass of wine.
I received a 'phone call from our doctor's surgery several months ago, was told they were updating their records and asked if I smoked. Before answering, I asked if they'd be asking me any other questions and when I was told 'no', I told them it was none of their business as it isn't, unless of course I develop health problems directly linked to smoking.
I see no reason why anyone should be judged and then denied medical treatment. As so many other posters have pointed out, where would it end? Would someone who is no longer overweight, no longer smokes or no longer drinks alcohol be denied treatment because they have a medical condition bought about by the fact that they used to do all, or one of those things?
A couple of months ago I took my brother to hospital for tests and was
at how many members of the medical profession were not just overweight but how many could have been judged as morbidly obese.
