The Science Behind The Sexy Years
The New Book by Suzanne Somers
By Edward Rosick, DO, MPH, MS

Tens of millions of women born during the post-World War II baby boom are now entering their forties and fifties, the time when a woman’s body undergoes the significant hormonal changes called menopause. While it seems that menopause is often in the news owing to some new revelation about the adverse effects of estrogen and progestin drugs, many women still do not have a clear picture of what is happening to their bodies as they enter middle age. Knowledge of how the body works, even on a basic level, can empower women to make sensible, positive decisions about their own health care.

Actress and author Suzanne Somers has written a new book, The Sexy Years: Discover the Hormone Connection, on how to not only survive but also prosper from the changes of middle age that affect both women and men. The Sexy Years is about more than the potential benefits of bioidentical hormone therapy; it is the story of how one woman overcame a battered childhood, breast cancer, and self-doubt to become one of the most recognizable and popular female icons in America today.

Overcoming Breast Cancer
Breast cancer will strike more than 200,000 women this year in the US alone, while claiming over 40,000 lives. As with many other cancers, the incidence of breast cancer continues to increase.

Fortunately for Suzanne, her cancer was detected early by the judicious use of ultrasound. Because of prompt detection and early surgery, the chance of her cancer recurring was slim. To further improve the odds against recurrence, her doctors recommended the standard course of postoperative radiation, chemotherapy, and a drug called tamoxifen that blocks estrogen receptor sites. After doing some research, however, Suzanne decided against chemotherapy and tamoxifen:

“The only problem I found . . . was that this drug [tamoxifen] would probably make me depressed . . . plus there was a 40% increased risk of heart attack, stroke, and pulmonary embolism. All this for only a 10% greater chance that the cancer would not reoccur? Didn’t sound like very good odds to me.”

Suzanne’s doctors wanted her to forgo the bioidentical hormones—estrogen, progesterone, and DHEA—that she was taking to alleviate her menopausal symptoms. While most oncologists dictate that women diagnosed with breast cancer must give up exogenous hormones, Suzanne decided to continue using them. Why? Because she had no desire to again experience the debilitating physical, emotional, and psychological symptoms of menopause.

Menopause: No Laughing Matter
In The Sexy Years, Suzanne uses scientific explanations and some insightful humor to describe the myriad changes a woman experiences as her levels of estrogen and progesterone fluctuate and plummet. As these all-important hormone levels change, a woman can experience what Suzanne dubs the “Seven Dwarfs of Menopause: Itchy, Bitchy, Sweaty, Sleepy, Bloated, Forgetful, and All-Dried Up.”

While Suzanne’s description of the “Seven Dwarfs” may be a bit too whimsical for those of a more scientific bent, these adjectives describe quite accurately the distressing symptoms experienced by women during menopause. Estrogen is produced in a woman’s ovaries, body fat, and adrenal glands. Natural estrogen has been shown to promote bone strength, protect heart and brain functioning, and maintain a woman’s sex drive. During perimenopause and menopause, fluctuating and decreasing estrogen levels can cause hot flashes, night sweats, mood swings, headaches, and vaginal dryness. Decreasing levels of another hormone, progesterone, can cause irritability, headaches, and anxiety.

Perils of Synthetic Hormone Replacement
It is not difficult to conclude that if menopausal symptoms are caused by a lack of estrogen and progesterone, then a woman could avoid these symptoms by replacing those hormones. Until recently, a significant percentage of women with menopausal symptoms were given the drugs Premarin®, a compound consisting of several different estrogens extracted from horse urine, and Provera®, a synthetically manufactured progesterone-like chemical. It was common practice for women to walk into a doctor’s office with menopausal complaints and walk out with the same prescription for Premarin® and Provera®.

In 2002, however, a government-funded study of hormone drug replacement therapy (part of the Women’s Health Initiative study) revealed that long-term use of Prempro™ (a combination of Premarin® and Provera®) increased the risk of breast cancer, heart attack, stroke, and blood clots. Because of this study, many mainstream doctors have stopped recommending these types of hormones to women with menopausal symptoms.

As Suzanne relates in The Sexy Years, Prempro™ was still in vogue when she was searching for a natural means of relief from her menopausal symptoms. She describes what was, until all too recently, a common occurrence in doctors’ offices around the nation:

“I went on to yet another doctor, who came highly recommended. He asked, ‘Why do you want to take natural hormones?’ I said, ‘Because I want to take the hormones I’ve lost in the aging process, not simply take away the symptoms.’ At that, he patted me on the head and said, ‘The drug companies know best, dear.’”

Discovering Bioidentical Hormone Replacement
Fortunately, Suzanne finally did find a physician who was well versed in integrative medicine and natural ways to deal with menopause. Dr. Diana Schwarzbein, a physician in Santa Barbara, CA, set Suzanne on a regimen of bioidentical hormone replacement therapy, with remarkable results:

“The good news was that I started to feel relief immediately. I began to sleep better, the hot flashes subsided, and slowly my sex drive returned. My thinking also got better, and the horrible itch on my legs went away.”

Suzanne’s experience with bioidentical hormones is not unique, yet the vast majority of mainstream physicians knows nothing about them. Why? Because most doctors have very little training in endocrinology, and because drug companies can make much more money by manufacturing and promoting their patented hormone drugs. As Suzanne details in her book, the tragedy is that while hormone drugs such as Provera® and Premarin® can eliminate some of the distressing symptoms of menopause, they do nothing to address the body’s loss of natural hormones:

“The lost hormones are gone for good. The life-sustaining nutrients supplied by your hormones are absent, and silently you begin to shut down metabolically. Aging and all that comes with it—aches, pains, weight loss or gain, disease, memory loss, and loss of mobility, agility, and libido—begin to set in.”

Switching to Bioidentical Hormones
With the huge success of The Sexy Years, many women will undoubtedly be asking their physicians about bioidentical hormone replacement therapy or researching the subject themselves. What they will find is that many mainstream physicians believe that there is no difference between bioidentical hormone replacement and synthetic hormone replacement. The question is, is there a real difference?

I believe that there is a difference. While those in mainstream medicine sometimes argue that Premarin® is a natural hormone because it is made from estrogens excreted in horse urine, is there anything “natural” about women taking horse estrogens? Provera®, which is supposed to replace progesterone, is in fact not even synthetic progesterone; rather, it is a progestin, a manufactured chemical that is unlike the chemical structure of natural progesterone.

Bioidentical hormones are specifically made to have a chemical structure that is identical to that of natural hormones produced by the human body. They are generally made from plant oils (such as diosgenin in Mexican yams) and directly match the structure and function of human hormones. With these facts in hand, it is ludicrous to say that bioidentical hormone replacement therapy and synthetic hormone replacement therapy are the same.

It is true that bioidentical hormone replacement therapy has not been subjected to the rigorous, double-blind, placebo-controlled studies that have been done using synthetic hormone replacement therapy. The studies that have been conducted, however, show the promise of using bioidentical hormone replacement to treat menopausal symptoms.1 A study that compared bioidentical hormone replacement with conventional hormone replacement showed that bioidentical therapy gave women the same symptomatic relief as conventional hormone replacement therapy. In a 1996 Japanese study that examined the use of bioidentical hormone replacement, specifically estriol, for osteoporosis, women who used estriol had significantly less bone loss. Natural progesterone has been shown to help alleviate hot flashes in women and have fewer side effects than Provera®.

So how should a woman who is considering bioidentical hormone replacement therapy proceed? According to The Sexy Years, she should strictly adhere to four rules:

  • Do not take a hormone that is not low or missing
  • Take only bioidentical hormones
  • Mimic normal physiology as much as possible
  • Track the hormone levels and their effects.

By following these rules, women can help alleviate menopausal symptoms. Moreover, as Suzanne states, “balancing hormones [with bioidentical hormone replacement therapy] is our best bet to fight the diseases of aging.”

The first part of The Sexy Years concludes with advice on how to find a doctor who is well versed in bioidentical hormone replacement therapy, an interview with a 45-year-old woman who is just beginning bioidentical hormone replacement therapy, and in-depth interviews with Dr. Schwarzbein and Dr. Uzzi Reiss, both of whom are nationally recognized experts in bioidentical hormone replacement therapy.
