Synthetic progesterones such as Provera also know as progestins have been used for over 35 years to treat menopause. Over the last 5 years, there has been mounting evidence showing that synthetic progesterones have numerous adverse effects on women. Progestins can cause thrombophlebitis, pulmonary embolism, fluid retention, depression, bloating, headaches, fatigue, and weight gain. Well, another study has been published that shows it is linked to hearing-loss in older women.
Progestins do not provide the “full spectrum of natural progesterone’s biological activity, nor are they as safe. It is a sad commentary on the pursuit of profit over women’s well-being that the pharmaceutical companies take perfectly good natural hormones that our bodies know and can use and alter them, creating synthetic compounds with similar hormonal effects but toxic side effects. Thus dies industrial profit influence the path of science and medicine.
