Nope, I hate it too. The used to have people go barefoot in those gown things to weigh in (which was much better, as the gowns weigh like NOTHING), but now they'll weigh you if you're wearing a leather jacket and biker boots for crying out loud.
AND they like announce your weight to the whole office, no matter who's nearby. Ugh.
What I do is wear lighter, smaller clothes and flip flops or slip-off shoes. If I'm feeling vulnerable and really want a good weigh-in at the doctor's, I'll do the clothing thing even if it's cold (I just wear warm stuff over it).
Maybe try weighing yourself with your lightest clothes on and see what difference that makes.
Or, think of it this way - the doctor weigh-in isn't the REAL one. You're going by your own scale, so that's your real one. It's the same as if you borrowed a friend's scale.
Don't worry about it too much - just remember that you're healthy and doing well.
