Hello bb, I had my subtotal at the age of 41 and started HRT about 3 years ago (oestrogen only, like you) after I had had symptoms for a while (and didn't know what was causing them). I haven't put on any weight at all, in fact I have lost about half a stone overall although I started thyroxin as well at the end of last year and think my metabolism has speeded up a bit as a result. I also don't eat a huge amount, if anything my appetite has decreased. I would just go with the flow, if I were you, take the HRT and enjoy the benefits it brings. Your doc will monitor you. I started on the 2mg dose and decreased to 1mg (which is low) at the start of the year although I must add that I am now on an SSRI as well - sertraline - due to being diagnosed with generalised anxiety disorder (which is likely meno related). I am feeling the benefits of the latter after a few weeks taking it although I still get days when I feel a bit anxious but it is better overall. Hope that helps.
