The Division of Endocrinology specializes in the diagnosis and management of a wide variety of hormonal disturbances seen in infancy, childhood and adolescence. The activities of the Division divide broadly into General Endocrinology and Diabetes.
Disorders of growth and sexual development are common reasons for referral to the General Endocrinology Clinic. Specific conditions relating to pituitary, thyroid , adrenal and gonadal dysfunction function are diagnosed and treated including certain genetic conditions with endocrine manifestations. In addition, a specialty clinic focusing on disorders of calcium and bone metabolism is offered.
The Diabetes Clinic provides services to a large number of patients and families with type 1 diabetes. We are a tertiary centre within the provincial pediatric diabetes network and provide a model of care that is multi-disciplinary. This includes the services and expertise of certified diabetes nurse educators, dieticians, social work and child life in addition to a team of pediatric endocrinologists/diabetologists. More rare forms of diabetes, including neonatal diabetes and MODY (Maturity Onset Diabetes of the Young) are also seen and managed through our centre as are youth with type 2 diabetes.
Transition to adult care is a challenge for many pediatric patients with chronic illnesses. A pediatric diabetes transition program has been developed that involves an endocrinologist, qualified in both pediatric and adult endocrinology, and the expertise of a specialist in adolescent medicine.
Close collaboration exists between the Division of Endocrinology and the Division of Children's Exercise and Nutrition (CENC).
