Bioidentical Hormone Replacement Therapy for Hormone
Imbalance Symptoms
Portland, Oregon

by Dr. Kathryn Retzler
As a primary care physician who specializes in natural medicine, I think the most important role
doctors can play is that of teacher – to provide complete, unbiased information so that patients can make
their own informed decisions. Following is a list of facts I provide my patients when they seek help for
hormone imbalance symptoms:
- Many women and men have significant symptoms as they age.
- No two people are identical in terms of their hormone production or the symptoms they
experience.
- Eating a healthy diet, exercising regularly, minimizing stress, and avoiding environmental
toxins are the foundations for preventing and managing hormone imbalance symptoms.
- If symptoms persist, bioidentical hormone replacement
therapy is an option that contains benefits and risks.
- People have different medication needs and drug detoxifying capacities. Testing baseline
hormone levels and following up with repeat testing after treatment is a reasonable way to determine
whether a patient is receiving too much hormone. Symptom improvement usually determines if a patient is
receiving enough medication.
- Synthetic hormones have been shown to have serious health consequences including increased risk
of breast cancer, blood clots, heart disease, and stroke. Synthetic oral testosterone has been shown to
increase the risk for liver inflammation and liver cancer.
- When I refer to the term Bioidentical hormones I am referring to the molecular structure of the hormone,
not the marketing term. That is, they are identical in structure to those hormones made by the
body. There is a large body of research involving the effectiveness of bioidentical estradiol,
progesterone, and testosterone. Bioidentical hormones do carry risks, especially when administered in
excessive dosages, outside of physiological levels; overall, however, they have a lower risk profile than
their synthetic counterparts (this is especially true for bioidentical progesterone vs. progestins, and
bioidentical testosterone vs. methyltestosterone). More research about long-term effects of bioidentical
hormone replacement therapy needs to be done.
- "Bioidentical hormones" are found in pharmaceuticals (e.g., bioidentical estradiol patches such
as Climara or Vivelle, bioidentical progesterone such as Prometrium, and bioidentical testosterone such
as Androderm, Androgel, or Testopel) as well as in individual preparations made by compounding
pharmacists.
- Compounded medications have been available since the 1930s. Organizations such as the
Professional Compounding Centers of America (PCCA) provide continuing education seminars for pharmacists
and physicians, as well as a source of FDA-approved ingredients subjected to quality assurance standards.
- Treating hormone imbalance requires a comprehensive understanding of endocrinology and
gynecology, as well as significant clinical experience.
I also share the following opinions with my patients:
- It makes sense to test baseline hormone production, and then if low levels and/or
hormone imbalance symptoms deem necessary, to prescribe low dosages of bioidentical hormones that
eliminate or minimize symptoms, or to bring a patient's hormone levels to within physiological range.
There is no established protocol for such treatment and potential risks exist; therefore, a conservative
approach to treatment is most prudent.
- Choosing an doctor who listens, provides you with information, and respects your treatment
decisions is your right and responsibility. Expect your physician to provide you with available research,
benefits, and risks of any treatment you choose. Do not be afraid to question any treatment or to make
your own healthcare decisions
