I had a complete hysterectomy 16 years ago. I suffered from hot flashes all day and night sweats all night. An OB/GYN had a seminar explaining the benefits of bioidenticals. Within three days of beginning treatment, my hot flashes and night sweats diminished and my memory started coming back. I was able to do crossword puzzles again and think clearly. I see so many women suffering from hot flashes and night sweats- not just for a few years. These can last into a woman's 70's. They have really made my senior years so much better. Even women without hysterectomies receive so much benefit, but those of us with hysterectomies no longer have any natural hormones, and those who have cancer cannot under any reason take hormones. I am 78 and am in much better health than those who do not take the bioidenticals. I still get around like most people in their 60's. Having hot flashes is something that most women had to endure until the bioidenticals came out.
