Dr. Niamh Mary Tallon

Dr. Niamh Tallon diagnoses and treats a wide range of hormonal and metabolic disorders, including:

Reproductive Health & Infertility (Endocrine Aspects)

• Amenorrhea (Absent Menstruation) & Oligomenorrhea (Infrequent Menstruation): Absence or infrequent occurrence of menstrual periods, which can be caused by a variety of hormonal imbalances affecting the hypothalamic-pituitary-ovarian axis.
• Hyperprolactinemia: Elevated levels of prolactin hormone in the blood, which can cause irregular periods, infertility, and milky nipple discharge (galactorrhea) in women, and low libido or erectile dysfunction in men.

Bone Health & Mineral Metabolism Disorders

• Paget's Disease of Bone: A chronic skeletal disorder that disrupts the normal bone remodeling process, resulting in bones that are enlarged, misshapen, and structurally unsound, leading to pain, deformities, and fractures.
• Disorders of Phosphate Homeostasis (Hypophosphatemia, Hyperphosphatemia): Imbalances in blood phosphate levels, which can be caused by various underlying conditions and affect bone health, muscle function, and energy metabolism.

Diabetes & Related Metabolic Disorders

• Type 2 Diabetes Mellitus (T2DM): A progressive condition characterized by insulin resistance (where the body's cells don't respond effectively to insulin) and/or relative insulin deficiency, often linked to genetics, lifestyle factors, and obesity.
• Gestational Diabetes Mellitus (GDM): Diabetes diagnosed during pregnancy that was not clearly overt diabetes prior to gestation, requiring careful management to ensure healthy outcomes for both mother and baby.
• Monogenic Forms of Diabetes (e.g., MODY, Neonatal Diabetes): Rare types of diabetes caused by mutations in a single gene, differing from the more common Type 1 and Type 2 diabetes in presentation and management.

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

• 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.
• 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.
• 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.
• 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.

Note: This list provides a general overview. Specific tests and treatments are determined after a thorough evaluation. Discuss with Dr. Tallon 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.

Are consultations, hormone tests, and treatments with Dr. Tallon, 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. Tallon, 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. Tallon's office, the hospital/clinic, or Medical Services Plan (MSP) directly.

Is a referral required to see Dr. Tallon, 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. Tallon. 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 is Hormone Replacement Therapy (HRT) and when might Dr. Tallon recommend it?

Hormone Replacement Therapy (HRT) involves taking medication to replace hormones that the body is no longer producing in sufficient amounts. Dr. Tallon 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. Tallon will discuss thoroughly.

Does Dr. Tallon deal with hormonal issues related to infertility or conditions like PCOS?

[IF PROVIDER IS REPRODUCTIVE ENDOCRINOLOGIST (REI):] Yes, as a Reproductive Endocrinologist and Infertility specialist (REI), Dr. Tallon has advanced training in diagnosing and treating complex hormonal disorders that affect fertility and reproductive health in both women and men. This includes conditions like Polycystic Ovary Syndrome (PCOS), ovulatory dysfunction, endometriosis-related hormonal issues, premature ovarian insufficiency, male hypogonadism impacting fertility, and recurrent pregnancy loss. She can manage ovulation induction, provide hormonal support for assisted reproductive technologies like IVF, and address other intricate reproductive endocrine problems. [ELSE:] A general Reproductive Endocrinologist (Fertility Specialist) like Dr. Tallon routinely manages common endocrine conditions that can impact reproductive health, such as thyroid disorders or prolactin imbalances, and can provide initial evaluation and management for Polycystic Ovary Syndrome (PCOS), including its metabolic and hormonal aspects. For complex infertility requiring assisted reproductive technologies (like IVF) or highly specialized reproductive surgeries, She would typically collaborate with or refer patients to a subspecialist in Reproductive Endocrinology and Infertility (REI).

What treatment options for osteoporosis might Dr. Tallon discuss?

If you are diagnosed with osteoporosis, Dr. Tallon will discuss a management plan aimed at reducing your risk of fractures. This starts with lifestyle modifications, including ensuring adequate intake of calcium and vitamin D (through diet and/or supplements), engaging in regular weight-bearing and muscle-strengthening exercises, smoking cessation, and limiting alcohol intake. Fall prevention strategies are also important. If medication is indicated based on your bone density (DXA scan) and fracture risk assessment (e.g., using FRAX or CAROC tools), options include antiresorptive medications that slow bone loss (like bisphosphonates or denosumab) or anabolic agents that stimulate new bone formation (like teriparatide or romosozumab). She will help choose the most appropriate therapy based on your individual circumstances, potential side effects, and treatment goals.
