Check into them, but beware! I was on the bioidentical hormones for 5 years (pellets implanted), and I was doing fine - or so I thought. Then at the age of 55, I became very ill with extreme fatigue, dizziness, and nausea. I had to quit my job because I couldn't function at work. The diagnosis was Mono, and then I found out SEVERAL other woman just in my small town who were getting the implants, were also diagnosed with Mono and couldn't get well. I finally found a gynecologist who explained that when you receive these implants, your body recognizes them as a foreign object and all your body's defenses concentrate on fighting off the foreign object, which leaves your body open to other infections and viruses. I wish I had NEVER started the implants. If they did cause this hideous illness I've been dealing with for 20 months now, they ruined my life and I've been trying to recover it ever since.
