About Us


Clinical Associate Professor Michelle Jack, established Sydney Paediatric Endocrinology in 2016. We aim to provide excellent, private specialist medical care for children and adolescents with diabetes and other endocrine (hormonal) conditions. We believe in an evidence-based approach that is tailored to meet the individual needs of children and their families. Together, we have more than 50 years of clinical experience in caring for children and teenagers with endocrine conditions.

What is Paediatric Endocrinology?

Paediatric endocrinology is the branch of medicine that provides medical care to infants, children and adolescents with problems affecting the endocrine glands in the body. Endocrine glands produce hormones. Hormones are chemicals that affect how other parts of the body function.

Endocrine glands include the pancreas, thyroid, adrenal, pituitary, ovaries and testes. Examples of hormones include insulin, thyroid hormone, cortisol, growth hormone and the hormones responsible for puberty, oestrogen and testosterone.

Paediatric endocrinologists are the medical specialists that care for children and adolescents with the following medical issues:

  • Diabetes mellitus (Type 1; Type 2; insulin pump therapy)
  • Insulin resistance and pre-diabetes
  • Obesity and weight management
  • Polycystic ovarian syndrome
  • Short stature
  • Delayed or precocious (early) puberty
  • Thyroid disorders including overactive or underactive thyroid gland, congenital hypothyroidism, autoimmune thyroiditis, Hashimoto's disease and Graves' disease.
  • Disorders of pituitary function including growth hormone deficiency and hypopituitarism
  • Disorders of adrenal function

Children cannot be treated as if they are only small adults. They have specific needs related to growth and development. Hormone problems affecting growth or sexual development can have significant negative consequences on a child's physical and emotional well-being. Paediatric endocrinologists understand these issues because of their training and experience.

Paediatric endocrinologists complete medical school then undertake at least three years of general paediatric training, followed by three years or more of specialised training in paediatric endocrinology. Many paediatric endocrinologists also complete a higher research degree, such as a PhD or medical doctorate, contributing to research and developing a capacity for life-long learning and practice of evidence-based medicine.
