Really don't understand what all the fuss is about. I am an ex-heavy smoker and luckily managed to give up five years ago but I would not be at all offended if I was tested for Carbon Monoxide.
To me its the same as being overweight. You don't need to test me to see if I'm overweight - but the MW still gets you to step on the scales. Although I am perfectly aware that being overweight isn't great for my health, in a first pregnancy I would much rather someone sat down and explain exactly what the risk factors were for me as a pregnant woman, because how else am I going to learn? Even if I know the exact medical reasons and implications of being overweight, why would I find it patronising?
IME the only people who feel patronised are the ones who think they know it all but actually don't, but when it comes to medical conditions, unless you're a medically qualified yourself, then do you really think you know more than your MW or doctor?
(BTW, I'm just about a normal weight (well, till I got up the duff - just using it for an example).
How many women out there really know exactly how "smoking when pregnant harms your baby". I consider myself to be well educated and up to date with many things (including being slightly OCD about all things pregnancy related) but still I only have some ideas about how smoking leads to low birth weight and breathing problems. If I were a smoker and someone were to sit down and explain things exactly what the implications were, I might, just might, find the facts were enough to tip me over the edge into giving up?
