Dr. Bonnie Alyssa Woolnough

Dr. Bonnie Woolnough diagnoses and treats a wide range of hormonal and metabolic disorders, including:

Reproductive Health & Infertility (Endocrine Aspects)

• Recurrent Pregnancy Loss (Endocrine Evaluation): Investigation into potential underlying hormonal factors that may contribute to repeated miscarriages, such as thyroid disorders, uncontrolled diabetes, or progesterone deficiency.
• Hormonal Management of Transgender Individuals (Gender-Affirming Hormone Therapy): Prescription and monitoring of hormone therapy for transgender individuals as part of their gender affirmation process, often in a multidisciplinary setting.
• Female Infertility (Ovulatory Dysfunction, PCOS-related, Luteal Phase Defect): Hormonal imbalances that can impair a woman's ability to conceive, such as problems with ovulation (e.g., due to PCOS), or issues with the uterine lining preparation.

Pituitary, Adrenal & Gonadal Axis Disorders

• Primary Aldosteronism (Conn's Syndrome): A condition where the adrenal glands produce too much aldosterone, leading to high blood pressure and low potassium levels.
• Adrenal Nodules (Incidentalomas) & Adrenal Tumors (e.g., Pheochromocytoma, Aldosteronoma): Masses found on the adrenal glands, often discovered incidentally. Evaluation is needed to determine if they are hormonally active or potentially malignant.
• Cushing's Syndrome & Cushing's Disease (Hypercortisolism): A hormonal disorder caused by prolonged exposure of the body's tissues to high levels of cortisol, either from medication (exogenous) or due to overproduction by the body (endogenous - e.g., pituitary or adrenal tumor).

Thyroid & Parathyroid Gland Disorders

• Thyroiditis (e.g., Subacute/De Quervain's, Postpartum, Silent/Painless): Inflammation of the thyroid gland, which can cause temporary hyperthyroidism followed by hypothyroidism, or persistent thyroid dysfunction, depending on the type.
• Primary Hyperparathyroidism: A disorder where one or more parathyroid glands become overactive, producing too much parathyroid hormone (PTH), leading to high blood calcium levels (hypercalcemia) and potential bone and kidney problems.
• Hypercalcemia & Hypocalcemia (Disorders of Calcium Metabolism): Evaluation and management of abnormally high or low levels of calcium in the blood, which can have various underlying endocrine or non-endocrine causes.

This list is not exhaustive. For personalized advice regarding your specific endocrine condition, please consult with Dr. Bonnie Woolnough.

• Expert Second Opinion Consultations for Complex or Rare Endocrine Disorders: Providing specialized second opinions on challenging endocrine diagnoses, interpretation of ambiguous hormone test results, or evaluation of complex or multi-faceted treatment plans.
• Comprehensive Endocrine System Consultation & Hormonal Health Evaluation: In-depth clinical assessment of potential hormonal imbalances and disorders affecting the endocrine glands (e.g., thyroid, pituitary, adrenal, pancreas, parathyroid, gonads). Includes detailed medical history, family history review, targeted physical examination, analysis of symptoms, and formulation of a personalized diagnostic and management plan.
• Transitional Care for Young Adults with Chronic Endocrine Conditions: Facilitating the smooth transition of adolescents and young adults with lifelong endocrine disorders (e.g., Type 1 diabetes, congenital adrenal hyperplasia, hypopituitarism) from pediatric to adult endocrine care services.
• Interpretation of Complex Hormonal Assays, Dynamic Endocrine Function Tests & Genetic Markers: Expert analysis and clinical correlation of specialized blood, urine, and saliva tests measuring various hormone levels. Includes interpretation of dynamic stimulation and suppression tests (e.g., ACTH stimulation, dexamethasone suppression, oral glucose tolerance test for acromegaly) to precisely evaluate endocrine gland function and identify genetic predispositions.
• Genetic Counseling Coordination & Testing for Hereditary Endocrine Neoplasia Syndromes & Familial Disorders: Risk assessment and coordination of genetic testing and counseling for individuals and families with suspected hereditary endocrine tumor syndromes (e.g., Multiple Endocrine Neoplasia - MEN1, MEN2; Von Hippel-Lindau), familial thyroid cancer, or other inherited endocrine conditions.
• Inpatient & Outpatient Management of Endocrine Emergencies & Crises: Acute diagnosis and management of potentially life-threatening hormonal imbalances such as diabetic ketoacidosis (DKA), hyperglycemic hyperosmolar state (HHS), thyroid storm, myxedema coma, adrenal crisis, severe hypoglycemia, and acute hyper/hypocalcemia, typically initiated in an emergency or hospital setting with ongoing outpatient follow-up.

Note: This list provides a general overview. Specific tests and treatments are determined after a thorough evaluation. Discuss with Dr. Woolnough for care relevant to your specific condition.

All medical services are provided in accordance with the standards of practice set by the College of Physicians and Surgeons of British Columbia (CPSBC) and relevant endocrinological care guidelines. Contact the clinic or your referring physician regarding new patient intake and referral processes.

Are consultations, hormone tests, and treatments with Dr. Woolnough, an Reproductive Endocrinologist (Fertility Specialist), covered by Medical Services Plan (MSP) in BC?

Medically necessary consultations with a licensed Reproductive Endocrinologist (Fertility Specialist) like Dr. Woolnough, most standard diagnostic hormone blood tests, dynamic endocrine function tests when indicated, and treatments for provincially insured endocrine conditions (e.g., diabetes, thyroid disorders, adrenal insufficiency, osteoporosis management as per guidelines) are generally covered by Medical Services Plan (MSP) in BC when a referral from a family doctor or another specialist is in place. Some newer or specialized medications (e.g., certain advanced diabetes drugs, some growth hormone therapies, specific osteoporosis agents), medical devices (like some insulin pumps or continuous glucose monitors and their supplies), or treatments considered primarily for lifestyle or cosmetic reasons may have different coverage criteria or require special authorization. It's crucial to discuss coverage specifics for any proposed investigation or treatment with Dr. Woolnough's office, the hospital/clinic, or Medical Services Plan (MSP) directly.

Is a referral required to see Dr. Woolnough, an Reproductive Endocrinologist (Fertility Specialist)?

Yes, for services covered by the provincial health plan, a referral from your family physician or another specialist (e.g., an internist, pediatrician, or gynecologist) is almost always required to schedule an appointment with an Reproductive Endocrinologist (Fertility Specialist) such as Dr. Woolnough. Endocrine system disorders often involve complex interactions and can have wide-ranging effects, so an initial assessment by your primary care provider helps determine if specialist care is needed and ensures that relevant preliminary tests and medical history are available to the endocrinologist. This facilitates a more focused and efficient consultation.

What conditions does an Reproductive Endocrinologist (Fertility Specialist) like Dr. Woolnough typically treat?

An Reproductive Endocrinologist (Fertility Specialist) is a medical doctor who specializes in diagnosing and treating diseases related to the endocrine system, which is the network of glands that produce and release hormones. These hormones control many important body functions, including metabolism (how your body gets energy from foods), growth and development, sexual function and reproduction, sleep, and mood. She is a Reproductive Endocrinologist (Fertility Specialist), concentrating on hormonal issues related to fertility, pregnancy, and reproductive health. Dr. Woolnough manages conditions such as diabetes, thyroid diseases (hyperthyroidism, hypothyroidism, nodules), osteoporosis, adrenal gland disorders (like Cushing's or Addison's disease), pituitary gland disorders, parathyroid and calcium imbalances, polycystic ovary syndrome (PCOS), and some forms of hypertension or lipid disorders related to hormonal imbalances.

What is Hormone Replacement Therapy (HRT) and when might Dr. Woolnough recommend it?

Hormone Replacement Therapy (HRT) involves taking medication to replace hormones that the body is no longer producing in sufficient amounts. Dr. Woolnough might recommend HRT for various conditions. For example, thyroid hormone replacement (levothyroxine) is used for hypothyroidism. For women experiencing troublesome menopausal symptoms, menopausal hormone therapy (MHT, using estrogen with or without progestogen) can be considered. For men with confirmed hypogonadism (low testosterone) and symptoms, testosterone replacement therapy may be an option. HRT is also crucial for individuals with adrenal insufficiency (cortisol/aldosterone replacement) or hypopituitarism (replacing deficient pituitary hormones). The decision to use HRT is highly individualized, based on the specific condition, symptoms, benefits, and potential risks, which Dr. Woolnough will discuss thoroughly.
