Dr. Melissa Mary Kallas-Koeman

Dr. Melissa Kallas-Koeman diagnoses and treats a wide range of hormonal and metabolic disorders, including:

Diabetes & Related Metabolic Disorders

• Diabetes Complications (Neuropathy, Nephropathy, Retinopathy - endocrine management aspects): Management focused on glycemic, blood pressure, and lipid control to prevent or slow the progression of nerve damage, kidney disease, and eye damage associated with diabetes.
• 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.
• 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.

Bone Health & Mineral Metabolism Disorders

• Osteoporosis (Postmenopausal, Senile, Glucocorticoid-Induced): A progressive bone disease characterized by decreased bone mass and density, leading to an increased risk of fractures, particularly of the hip, spine, and wrist.
• 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.
• 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.

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.
• Primary Aldosteronism (Conn's Syndrome): A condition where the adrenal glands produce too much aldosterone, leading to high blood pressure and low potassium levels.

This list is not exhaustive. For personalized advice regarding your specific endocrine condition, please consult with Dr. Melissa Kallas-Koeman.

• 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.
• 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. Kallas-Koeman for care relevant to your specific condition.

Are consultations, hormone tests, and treatments with Dr. Kallas-Koeman, an Endocrinologist (Diabetes & Metabolism Focus), covered by Alberta Health Care Insurance Plan (AHCIP) in AB?

Medically necessary consultations with a licensed Endocrinologist (Diabetes & Metabolism Focus) like Dr. Kallas-Koeman, 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 Alberta Health Care Insurance Plan (AHCIP) in AB 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. Kallas-Koeman's office, the hospital/clinic, or Alberta Health Care Insurance Plan (AHCIP) directly.

Is a referral required to see Dr. Kallas-Koeman, 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. Kallas-Koeman. 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. Kallas-Koeman?

An Endocrinologist (Diabetes & Metabolism Focus) like Dr. Kallas-Koeman 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). She 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. Kallas-Koeman deal with hormonal issues related to infertility or conditions like PCOS?

Yes, as a Reproductive Endocrinologist and Infertility specialist (REI), Dr. Kallas-Koeman 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.

What treatment options for osteoporosis might Dr. Kallas-Koeman discuss?

If you are diagnosed with osteoporosis, Dr. Kallas-Koeman 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.

How does Dr. Kallas-Koeman typically approach managing diabetes (Type 1 or Type 2)?

Dr. Kallas-Koeman'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.
