Ladies - we can't hold back the ageing process - energy, stamina, muscle loss etc will happen whether on HRT or not.
Oestrogen can help reduce ‘some' of the negative effects of ageing, supporting bone density and helping to prevent urogenital atrophy but it cannot keep us young. I was a professional dancer, have always been very active and now at 62 I have had to adjust my life to include lots of good brisk walking, Pilates, leading the odd dance class myself and eating small meals regularly to avoid blood sugar lows. Relaxation and pacing myself are absolutely key to my wellbeing.
Instead of trying to push too hard and maintain the things you did through your 40s and early 50s, perhaps consider adjusting what you do to balance life better.
I found high doses of oestrogen made me feel awful and I'm not convinced big doses of hormones are the answer unless you are not absorbing the hormones from HRT for some reason. A blood test to look at oestrogen levels would be advisable to see what you levels are.
BE kind to yourselves ladies. Dg x
