Natural Progesterone Reduces Hot Flushes and Is Safe for the Heart
Confusing synthetic progestins found in HRT with bioidentical progesterone has led to some wrong assumptions about the effectiveness and safety of the hormone and hidden its real benefits to women.
A new study from a research team at the University of British Columbia has clarified a real confusion among women, and their doctors. We have known for over ten years that oestrogen and progestins increase the risks of heart attack and stroke and this is one of the reasons why long term use of HRT is now discouraged.
Unfortunately there was also a widespread assumption at that time that natural progesterone would have the same risks because of its molecular similarity to progestins, what they failed to see were the very real differences between the two. The late Dr John Lee, the pioneer of natural progesterone cream usage, likened it to having a key cut: the progestin key goes in the lock but does not open the door, but bioidentical progesterone is recognised by the body as a genuine key and the door to hormone balance is readily opened.
Progesterone is safe for heart health, and effective for flushes and night sweats
This new study was reported earlier this year and confirmed that treatment with progesterone was shown to alleviate severe hot flushes and night sweats with no cardiovascular risk. This is no surprise to bioidentical doctors who know progesterone’s role in actually supporting heart health and effectively reducing menopausal symptoms but this study by Dr. Jerilynn C. Prior, a professor of endocrinology and the head of Centre for Menstrual Cycle and Ovulation Research andwho was a colleague of Dr John Lee, makes positive reading.
HRT has been the preferred way for doctors to deal with menopausal symptoms using a combination of synthetic oestrogen and progesterone to reduce the frequency and severity of hot flashes and night sweats, as well as to prevent osteoporosis. However many women find themselves unable to tolerate it, and the ongoing research over this period has shown that it increased the risk of heart disease and strokes plus breast and other cancers.
HRT formulas included a progestin (not progesterone) to guard against a thickening of the endometrium which could lead to uterine cancer. Women who have had a hysterectomy were given oestrogen-only HRT which has led to more problems as they are having unopposed oestrogen and no protection from progesterone at all and so the increased risk of heart disease and breast cancer still remains.
Oestrogen only HRT is not considered safe as a long-term prevention against osteoporosis or any other conditions of aging. Since oestrogen use began to decline, figures from the USA indicate that breast cancer rates have started to fall and health statisticians believe the two trends are linked.
The three month trial took 110 women and gave half a placebo and half progesterone and the researchers used each woman’s age and changes in blood pressure and cholesterol levels to calculate their 10-year risk of a heart attack and other blood vessel diseases. There was no increased risk between those taking progesterone and the control group. Dr Prior commented
“Many women are apprehensive about taking progesterone for hot flashes because of a belief that it carries the same – or even greater – risks than oestrogen. We have already shown that the benefits of progesterone alone have been overlooked. This study demonstrates that progesterone’s risks have been overblown.”
Dr Prior has been prescribing progesterone since it became available in Canada in 1995, for postmenopausal women to treat flashes and night sweats, and for peri-menopausal women to alleviate hot flashes, heavy menstrual flow and sore breasts.
