Bioidentical Hormone Therapy/BHRT

Bioidentical Hormone Replacement Therapy (BHRT) refers to the use of hormones that are structurally identical to those naturally produced by the human body, most commonly estrogen, progesterone, and thyroid hormones.

BHRT is one option that may be considered in the management of symptoms related to hormonal changes, particularly during perimenopause and menopause, following clinical assessment.

BHRT is not a first-line or universal treatment and is only considered when clinically appropriate based on symptoms, medical history, and laboratory findings.

Clinical Purpose of BHRT

BHRT may be used within a broader clinical context to support symptom management associated with hormonal changes.

It may be considered to:

Response varies between individuals and outcomes cannot be guaranteed.

Symptoms That May Be Considered in Assessment

BHRT may be discussed as part of care when individuals present with symptoms such as:

Hot flashes and night sweats
Sleep disturbance
Mood changes or emotional fluctuations
Fatigue
Changes in libido
Menstrual irregularities (in appropriate clinical contexts)
Vaginal dryness

Conditions such as endometriosis, fibroids, or infertility are not treated directly with BHRT, but may be considered within broader hormonal assessment and care planning.

Potential Clinical Context (Not Indications)

Hormonal therapy may be discussed in relation to:

Perimenopausal or menopausal transitions
Documented hormonal deficiencies
Symptom patterns consistent with hormonal fluctuation

BHRT is not used as a standalone treatment for chronic disease prevention.

Potential Benefits (Individual Variation Applies)

Some individuals may experience improvements in:

Sleep quality
Energy levels
Mood stability
Vasomotor symptoms (e.g., hot flashes)
Vaginal dryness

These outcomes are variable and depend on multiple factors including formulation, baseline hormone status, dosing, and individual response. They are not guaranteed outcomes.

Prescribing & Clinical Use (Ontario)

In Ontario, naturopathic doctors with additional prescribing authority may prescribe certain bioidentical hormones following appropriate training and certification.

These may include:

Bioidentical progesterone
Transdermal estradiol and estriol preparations
Desiccated thyroid hormone (where clinically indicated and within scope)

All prescribing is based on clinical assessment and includes appropriate monitoring and follow-up where indicated.

Treatment is reviewed regularly and may be adjusted or discontinued based on response, safety considerations, and clinical status.

Access to BHRT

BHRT is available only to active patients under ongoing care
A full clinical assessment is required prior to prescribing
Laboratory testing is typically used to guide prescribing decisions
Treatment is reviewed and adjusted based on response and safety considerations

Professional Standards

Naturopathic doctors in Ontario must complete additional prescribing education and examination before being authorized to prescribe hormonal therapies.

Prescribing is governed by regulatory standards and is based on clinical assessment rather than patient request alone.
