Blog — #Progesterone

By Dr. Kate Placzek, ZRT Laboratory 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.  SUMMARY The main focus of this blog is the time in a woman’s life...

Original of this artickle was Posted by Dr Kate Placzek, on ZRT Laboratory. Keeping awake, throwing blankets off at night. Fatigue and irritation punctuated throughout the day by heat dissipating from every pore, clouding thoughts, reinforcing forgetfulness. Hair falling out so stubbornly fast. Clothes choosing when to fit. Flooding periods coming sporadically, unexpectedly. They call it “the change of life” – but I feel like a different person altogether. What is happening?          In perimenopause, the physiological landscape is subject to tremendous change with estradiol and progesterone at the heart of the transition. Progesterone levels fall quickly – no ovulation...

A Recipe for Beating (and Preventing) Breast Cancer The latest research on natural progesterone and breast cancer clearly indicates how important it is for women to maintain healthy, normal levels of progesterone that are in proper balance with estrogen. Doing so could not only increase many womens’ chances of recovering from breast cancer – as the latest research indicates – but could also help them to avoid getting breast cancer in the first place. As Dr. John Lee and Dr. David Zava point out in their book, hormonal imbalances have reached epidemic proportions in most developed countries over the last...

 A large team of scientists working on multiple continents published a research study that came to startling conclusions about breast cancer and natural progesterone. The team determined that unlike synthetic progestins, which increase breast cancer risks, natural progesterone has the potential to slow the growth of many breast cancer tumors or even shrink them. While this finding is stunning, it is not new. It is one of several conclusions about progesterone that Dr. John R. Lee, M.D. and Dr. David Zava, Ph.D. made more than a decade ago when they co-wrote the book, What Your Doctor May Not Tell You...

I remember the uncertain winter of my entrance into perimenopause so well. It began in my late 40s, with hot flashes that came on like heat waves every half hour. In the dead of winter, I found myself flinging open windows to let in the freezing air; I soon found out that having hot flashes in winter was nothing like having them in summer, when the added heat and humidity made them feel more like mini-meltdowns.   How to Cool Down without Melting Down Perimenopause is a hormonally challenged transition during which the ovaries gradually begin to make less estrogen and progesterone; it...
