The US Preventative Services Task Force is advising post-menopausal women to avoid taking progestin and/or estrogen for the prevention of chronic conditions. Those would include heart disease dementia or bone fractures.
The groups says, for these illnesses, the risk outweighs any benefits.
This latest recommendation is largely based on revised analyses of the landmark Women's Health Initiative.
But this does not necessarily apply to women who use HRT to reduce menopause symptoms such as hot flashes and night sweats.
