Brief Summary:
The purpose of this study is to determine whether young women with functional hypothalamic amenorrhea (premenopausal HypoE) is associated with risk factors for pre-clinical cardiovascular disease (CVD).
For this study, the investigators will measuring vascular function and inflammatory markers on:
* young women with functional hypothalamic amenorrhea (\>3 months of no menstrual cycle due to low estrogen)
* young women with regular menstrual cycles not on hormone therapy.
* recently menopausal women (\<3 years from final menstrual period) not on hormone therapy.
Premenopausal HypoE participants (women with functional hypothalamic amenorrhea) will be randomized to use either an estrogen patch or a placebo patch (no active medicine) for 12 weeks, followed by estrogen or placebo patch plus progesterone or placebo pills for 2 additional weeks. The investigators are looking to see if estrogen improves vascular and inflammation.
Detailed Description:
Study Aims:
1. To test the hypothesis premenopausal HypoE (women with FHA) is associated with pre-clinical CVD as determined by reductions in vascular endothelial function.
2. To test the hypothesis premenopausal HypoE (women with FHA) is associated with increased immune-mediated inflammation.
3. To test the hypothesis whether estrogen replacement can reduce inflammation and improve vascular endothelial function in premenopausal HypoE women (women with FHA).
In a randomized, double-blind placebo-controlled trial in premenopausal HypoE women (women with FHA) the investigators will test 12 weeks of transdermal estradiol 0.1 mg/day patch or placebo followed by 2 weeks of estradiol plus progesterone 200mg (for endometrial safety) on vascular endothelial function and immune-mediated inflammation versus placebo. Patches will be applied by the participant to the lower abdomen twice weekly, alternating sides.
The investigators will be using non-invasive tests to measure vascular function to measures reactive hyperemic index (RHI) using peripheral arterial tonometry (PAT)
