Posted by Margaret Groves on Friday, 15 September

One of the primary objectives of the Women's Health Initiative was to see if postmenopausal hormone replacement therapy (HRT) improved long-term risk of coronary heart disease, among other chronic diseases.

However, the combined estrogen/progestin (Prempro) arm was halted in 2002, citing that the participants’ risk of cardiovascular disease outweighed any potential benefit of HRT in the prevention of colorectal cancer and bone fracture [1]. The conjugated equine estrogen (CEE)-only arm was also halted in 2004 citing no improvement in heart disease risk but an increased incidence of stroke, and no benefit in terms of fractures, although there was a reduced breast cancer risk [2].

Yet the WHI investigators published a report this week [3] after a cumulative follow-up of 18 years finding that there was no overall increase in all-cause, cardiovascular, or cancer mortality as a result of either Prempro or CEE-only treatment during their participation in the trial.

Providers routinely call ZRT for support in addressing low libido for their patients during the menopausal transition.

Low libido is a multidimensional issue that can have a little bit of everything infused into its mosaic. It's not uncommon that the symptom of low libido is accompanied by fatigue, sleep disturbances, mood swings, and perhaps even mild depression. Helping patients with waning libido is attainable, and one just needs to know where to look. There are a number of factors that appear to be intimately linked to libido that can be divided into three broad categories – endocrine, lifestyle, and physical.

5 Tips to Being a Balanced Menopausal Mom

Menopausal mom facing away from daughter

How well I remember the dismaying shock of menopause storming into my life...I was in my late 40s then and had just moved back to the States from England – a culture clash and-a-half. My daughters were still pretty young, 9 and 6 years old, and having a hard time adjusting to new schools on top of coping with an older mom whose hormones were suddenly in full revolt.

As I recall, Christmas was fast approaching but with hot flashes hitting me every 20 minutes, and mood swings in between, no amount of holiday cheer could cheer this mama up. In the dead of winter I kept cranking the windows wide open, and G’awd help anyone who complained of frostbite. “Try putting on another sweater,” I’d bark at my husband and shivering little ones. Needless to say, my family was beginning to hate me.

Estrogen. 

We've heard Dr. Zava call it the "angel of life, and the angel of death." Too much can be hazardous. Too little can be problematic also. 

Not many people realize this, but estrogen plays a role in more bodily functions than just reproduction. In fact, estrogen has many important functions in the brain. 

Studies show that decreasing levels of estrogen can cause two of the most common perimenopause symptoms hot flashes and mood fluctuations. Curious how this happens? Read on to learn the details of this biochemistry.
