This is something I've started to notice and I've measured myself on several occasions, but I've actually lost height. pre-hrt I was 5'9" and I've been like that for a long while. But now, I'm affirmed 5'7.5" feet.
My brother visited me the other day (he's starting to warm up to talking to me and visiting me, he stopped talking to me for 8 months when I told him I was transitioning). Anyway, my brother has always been shorter than me (he's 5'8"), but now he's taller. He's also much bigger -- although, he hasn't changed in size, but I have.
It's really surreal to see my brother, because we used to look very much alike. We had the same build and looks. But now, I'm much, much smaller. It's a weird feeling, like looking into a mirror into the past. My shoulders are much smaller, my arms, everything. He's so huge, and I used to be built like that.
Anyway, I was wondering if anyone else noticed that they've lost some height while on HRT. I think it's because I've lost a lot of muscle mass.
Oddly enough, my shoe size is a bit smaller as well. And I wouldn't think that feet would shrink.
