Dr. Richard Dumas

Dr. Richard Dumas diagnoses and treats a wide range of hormonal and metabolic disorders, including:

Diabetes & Related Metabolic Disorders

• 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.
• Hypoglycemia (Low Blood Sugar - various causes): Abnormally low blood glucose levels, which can occur as a side effect of diabetes treatment (insulin or certain oral medications), or due to other underlying conditions like insulinoma or adrenal insufficiency.
• Prediabetes & Insulin Resistance: A state where blood glucose levels are higher than normal but not yet high enough for a type 2 diabetes diagnosis. Insulin resistance is a key feature, where cells don't respond well to insulin.

Bone Health & Mineral Metabolism Disorders

• 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.
• Osteopenia (Low Bone Mass): A condition where bone mineral density is lower than normal peak density but not yet low enough to be classified as osteoporosis. It indicates an increased risk for developing osteoporosis.

Thyroid & Parathyroid Gland Disorders

• Hypothyroidism (Underactive Thyroid - e.g., Hashimoto's Thyroiditis, Post-Ablation): A common condition where the thyroid gland doesn't produce enough thyroid hormone, leading to symptoms like fatigue, weight gain, cold intolerance, constipation, and dry skin.
• 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.
• Thyroid Nodules & Multinodular Goiter: Solid or fluid-filled lumps (nodules) that form within the thyroid gland, or an enlarged thyroid gland with multiple nodules. Most are benign but require evaluation for cancer risk.

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

• 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.
• 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.
• 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.
• 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.
• 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.
• 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.

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

Are consultations, hormone tests, and treatments with Dr. Dumas, an Endocrinologist (Diabetes & Metabolism Focus), covered by Régie de l'assurance maladie du Québec (RAMQ) in QC?

Medically necessary consultations with a licensed Endocrinologist (Diabetes & Metabolism Focus) like Dr. Dumas, 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. Dumas's office, the hospital/clinic, or Régie de l'assurance maladie du Québec (RAMQ) directly.

Is a referral required to see Dr. Dumas, an Endocrinologist (Diabetes & Metabolism Focus)?

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 Endocrinologist (Diabetes & Metabolism Focus) such as Dr. Dumas. 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. Dumas recommend it?

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

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

Yes, as a Reproductive Endocrinologist and Infertility specialist (REI), Dr. Dumas 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.

What treatment options for osteoporosis might Dr. Dumas discuss?

If you are diagnosed with osteoporosis, Dr. Dumas 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). He will help choose the most appropriate therapy based on your individual circumstances, potential side effects, and treatment goals.

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

When evaluating a thyroid nodule, an Endocrinologist like Dr. Dumas 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. Dumas 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.
