Dr. Robert David Barnes 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.
• Dyslipidemia (High Cholesterol, High Triglycerides, Low HDL): Abnormal levels of lipids (fats) in the blood, including elevated LDL ('bad') cholesterol, high triglycerides, or low HDL ('good') cholesterol, significantly increasing cardiovascular disease risk.

Bone Health & Mineral Metabolism Disorders

• 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.
• 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.
• Rickets & Osteomalacia: Conditions characterized by softening and weakening of bones, typically due to severe and prolonged vitamin D deficiency. Rickets occurs in children, leading to skeletal deformities, while osteomalacia occurs in adults.

Pituitary, Adrenal & Gonadal Axis Disorders

• 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.
• Male Hypogonadism (Primary & Secondary Testosterone Deficiency): Condition in which the body doesn't produce enough testosterone, leading to symptoms like low libido, fatigue, muscle loss, and infertility. Can be due to testicular failure or pituitary/hypothalamic issues.
• Hypopituitarism (Panhypopituitarism, Isolated Hormone Disclosures): Condition where the pituitary gland fails to produce adequate amounts of one or more crucial hormones (e.g., GH, ACTH, TSH, LH/FSH, ADH), requiring hormone replacement therapy.

This list is not exhaustive. For personalized advice regarding your specific endocrine condition, please consult with Dr. Robert David Barnes.

• 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.
• 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.
• 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.
• 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.
• 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. Barnes for care relevant to your specific condition.

All medical services are provided in accordance with the standards of practice set by the Collège des médecins du Québec (CMQ) 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. Barnes, 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. Barnes, 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. Barnes's office, the hospital/clinic, or Régie de l'assurance maladie du Québec (RAMQ) directly.

Is a referral required to see Dr. Barnes, 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. Barnes. 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 Endocrinologist (Diabetes & Metabolism Focus) like Dr. Barnes typically treat?

An Endocrinologist (Diabetes & Metabolism Focus) 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. He is an Endocrinologist (Diabetes & Metabolism Focus), specializing in Diabetes & Metabolism. Dr. Barnes 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. Barnes recommend it?

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