I've heared about height decrease/shrinking a few incehs (1-2 i think)
and i also hearde that it comes from slight collapse of spine since muscles
supporting it also shrink. Athough, my endo said HRT does not reduce height!
But sure there was some evidence of that, on pretty much every forum on line
u can hear from some girls that thay have shrank a bit.
And in your case FallenLeaves, it certanly isn't shrinking from ageing so i assume
it is hrt. How long have u been on it? I just stated and want to see when to check it
out myself.

As for the waight: HRT will increase you apetite and decrease your metabolism so
we are indeed prone to weight gain i.e. if you don't cahnge your eating habits after
u start hrt you will find yourself gaining weight even though you eat the same amounts
before.
If you are not satisfied with your weight, try reducing your daily calorie intake, and
try to exercisse, but moderately, because i heared that intenisve exercisse can actually
boost your androgen levels, which will slow HRT. My endo said 3 times a week is enough.
Hope i helped somehow. take care
