I've been having similar (but nowhere near so arsey - I suspect my resting bitch face and ability to draw blood from instinctively adopting my grandmother's clipped tones when irked have something to do with it) conversations with doctors for many, many years.
They always seem so disappointed that my blood pressure, heart rate, blood sugar and other test results are so very, very normal - I've lost count of the number of times I've been asked 'Are you sure? Really?' Well, you can test it again, I'm perfectly happy to oblige with yet another test, but it was fine 2/6/10 weeks/3/6/9 months ago and I don't think anything has changed in the last few days that would make a difference to the most recent result.
The most recent one was when going for the obligatory You're Knocking on a Bit Now, Love checkup I was pressganged into when trying to book a (completely normal, by the way) smear test. I phoned up for the results 'The Nurse will call you soon because there's something she needs to discuss with you'. OK, so something dodgy's shown up, fair enough, probably blood sugar, maybe cholesterol.
She calls the next day and, yes, my blood sugar is too high, as is my cholesterol and I 'need to stop eating all the cakes, fried foods, chocolates, pies and sweets that we all love so much'. And cut down on salt because high blood pressure puts you at risk of dying. Hang on. I don't eat any of those things. What exactly are the numbers we're talking about here?
I had to ask her three times before she answered.
Blood sugar was - normal.
Cholesterol was - normal. Even with taking a medication that is known to raise levels. The ratio was perfect between 'good' and 'bad'.
And my blood pressure? A healthy normal, if not a little low. Which is what always happens, as I was specifically told years ago to slightly increase sodium because my blood pressure is so low that I often faint if I don't.
I appreciate the concern and yes, it would obviously be a very good thing if I were to be lighter because I could spend more on clothes - but when they get to the point of lying about test results to meet their confirmation bias, they really aren't engendering trust in their advice.
I'm past getting upset by it now. Because if I'm getting upset, I'm not making sure that my actual medical conditions that I have had since childhood and completely independently of being overweight, underweight and everything in between are being effectively treated.
However, if somebody were actually rude to me, I would complain. Politely and calmly. But very strongly.
