Dr. Andrew Kum-Charm Mok

Dr. Andrew Kum-Charm Mok 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.
• Male Infertility (Hormonal Causes, e.g., Hypogonadotropic Hypogonadism): Endocrine disorders contributing to male infertility, such as low testosterone production due to pituitary or testicular issues, affecting sperm production and function.

Diabetes & Related Metabolic Disorders

• 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.
• Type 1 Diabetes Mellitus (T1DM): An autoimmune condition resulting in the destruction of insulin-producing beta cells in the pancreas, requiring lifelong insulin therapy for survival and glucose management.

Pituitary, Adrenal & Gonadal Axis Disorders

• Diabetes Insipidus (Central or Nephrogenic): A rare disorder characterized by intense thirst and the excretion of large amounts of dilute urine, caused by problems with the hormone vasopressin (ADH) or the kidneys' response to it.
• 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).

This list is not exhaustive. For personalized advice regarding your specific endocrine condition, please consult with Dr. Andrew Kum-Charm Mok.

• 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.
• 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.
• 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.
• 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.

Are consultations, hormone tests, and treatments with Dr. Mok, an Reproductive Endocrinologist (Fertility Specialist), covered by Régie de l'assurance maladie du Québec (RAMQ) in QC?

Medically necessary consultations with a licensed Reproductive Endocrinologist (Fertility Specialist) like Dr. Mok, 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 Régie de l'assurance maladie du Québec (RAMQ) in QC 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. Mok's office, the hospital/clinic, or Régie de l'assurance maladie du Québec (RAMQ) directly.

Is a referral required to see Dr. Mok, 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. Mok. 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.

Dr. Mok mentioned 'dynamic endocrine testing'. What does that mean?

Dynamic endocrine testing involves tests that assess how your endocrine glands respond when stimulated or suppressed by specific substances. Unlike simple blood tests that measure baseline hormone levels, these tests evaluate the gland's functional reserve or its responsiveness to normal control mechanisms. For example, an ACTH stimulation test checks how well your adrenal glands produce cortisol when stimulated. A dexamethasone suppression test helps diagnose Cushing's syndrome by seeing if cortisol production can be suppressed. An oral glucose tolerance test can be used to diagnose diabetes or acromegaly. These tests usually involve taking a baseline blood sample, then administering a medication or substance, followed by one or more timed blood samples to measure hormone changes. Dr. Mok uses these tests for more precise diagnosis of certain complex endocrine conditions.

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

Yes, as a Reproductive Endocrinologist and Infertility specialist (REI), Dr. Mok 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. He can manage ovulation induction, provide hormonal support for assisted reproductive technologies like IVF, and address other intricate reproductive endocrine problems.

How does Dr. Mok typically approach managing diabetes (Type 1 or Type 2)?

Dr. Mok's approach to diabetes management is comprehensive and individualized. For Type 1 diabetes, the focus is on intensive insulin therapy (using multiple daily injections or an insulin pump), continuous glucose monitoring (CGM), carbohydrate counting, and education on managing blood sugar fluctuations and preventing hypoglycemia. For Type 2 diabetes, management often starts with lifestyle modifications (diet, exercise, weight loss), followed by oral medications if needed. Newer injectable medications (like GLP-1 receptor agonists or SGLT2 inhibitors) or insulin may be added as the disease progresses or if blood sugar targets aren't met. In both types, a key goal is to achieve optimal glycemic control (measured by HbA1c and glucose monitoring) while minimizing side effects and preventing long-term complications affecting the eyes, kidneys, nerves, and cardiovascular system. This often involves a multidisciplinary team approach.

I have a thyroid nodule. What can I expect during an evaluation with an Endocrinologist like Dr. Mok?

When evaluating a thyroid nodule, an Endocrinologist like Dr. Mok will conduct a thorough assessment. This typically involves reviewing your medical history (including any symptoms of thyroid dysfunction or family history of thyroid disease), performing a physical examination of your neck and thyroid gland, and ordering blood tests to check your thyroid function (TSH, and possibly free T4, T3, and thyroid antibodies). A thyroid ultrasound is almost always performed to precisely characterize the nodule's size, number, and sonographic features (e.g., solid, cystic, calcifications, irregular margins). Based on these ultrasound characteristics and the nodule's size, Dr. Mok will determine if a fine-needle aspiration (FNA) biopsy is needed to obtain cells for microscopic examination to rule out thyroid cancer. Most thyroid nodules are benign.
