Dr. Jean-Hugues Brossard

Dr. Jean-Hugues Brossard diagnoses and treats a wide range of hormonal and metabolic disorders, including:

Diabetes & Related Metabolic Disorders

• 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.
• 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

• 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.
• Vitamin D Deficiency and Insufficiency: Inadequate levels of vitamin D, which is essential for calcium absorption and bone mineralization, leading to potential bone pain, muscle weakness, and increased fracture risk.

Pituitary, Adrenal & Gonadal Axis Disorders

• 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.
• Polycystic Ovary Syndrome (PCOS) - Endocrine Management: A common hormonal disorder among women of reproductive age, characterized by irregular periods, signs of androgen excess (e.g., hirsutism, acne), and polycystic ovaries on ultrasound, with associated metabolic risks.

This list is not exhaustive. For personalized advice regarding your specific endocrine condition, please consult with Dr. Jean-Hugues Brossard.

• 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.
• 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.
• 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.

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

Are consultations, hormone tests, and treatments with Dr. Brossard, 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. Brossard, 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. Brossard's office, the hospital/clinic, or Régie de l'assurance maladie du Québec (RAMQ) directly.

Is a referral required to see Dr. Brossard, 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. Brossard. 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 types of diagnostic tests are commonly used by an Endocrinologist (Diabetes & Metabolism Focus) like Dr. Brossard?

An Endocrinologist (Diabetes & Metabolism Focus) like Dr. Brossard utilizes a variety of tests to diagnose endocrine disorders. Blood tests are fundamental for measuring levels of specific hormones (e.g., TSH, free T4, cortisol, ACTH, testosterone, estrogen, LH, FSH, insulin, HbA1c, prolactin, PTH, calcium, vitamin D). He often orders dynamic endocrine function tests, where hormone levels are measured after administering a stimulating or suppressing agent (e.g., ACTH stimulation test for adrenal function, oral glucose tolerance test for diabetes/acromegaly, dexamethasone suppression test for Cushing's). Imaging studies like thyroid ultrasounds, CT scans, or MRIs of the pituitary or adrenal glands are common. Bone mineral density (DXA) scans assess for osteoporosis. For thyroid nodules, a fine-needle aspiration (FNA) biopsy might be performed or arranged.

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

As a general Endocrinologist (Diabetes & Metabolism Focus), Dr. Brossard 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, he would typically collaborate with or refer patients to a subspecialist in Reproductive Endocrinology and Infertility (REI). However, he has extensive experience in managing hormonal disorders affecting fertility and reproductive health.

What symptoms might lead my doctor to refer me to an Endocrinologist like Dr. Brossard?

Your doctor might refer you to an Endocrinologist like Dr. Brossard if you experience symptoms or test results suggestive of a hormone imbalance or endocrine gland problem. This could include unexplained significant weight gain or loss; persistent fatigue or lethargy; mood or energy changes; excessive thirst or urination; high or fluctuating blood sugar levels; symptoms of thyroid dysfunction such as palpitations, heat or cold intolerance, hair or skin changes; bone density loss; recurrent kidney stones; menstrual irregularities or fertility issues; unexplained high blood pressure; or physical signs like excessive hair growth, acromegaly features, or Cushing's syndrome.

What treatment options for osteoporosis might Dr. Brossard discuss?

If you are diagnosed with osteoporosis, Dr. Brossard will discuss a management plan aimed at reducing your risk of fractures. This includes lifestyle modifications such as adequate calcium and vitamin D intake, weight-bearing and muscle-strengthening exercises, smoking cessation, and alcohol moderation. Fall prevention strategies are also emphasized. Pharmacologic options may include antiresorptive medications like bisphosphonates or denosumab, or anabolic agents such as teriparatide or romosozumab, tailored to your individual risk profile and preferences.
