Lea D. Delbridge is an Endocrinologist based at Royal North Shore Hospital in Sydney, NSW.
Endocrinology is all about hormones and how they affect the whole body. In day-to-day work, Lea looks after people with long-term hormone and metabolic conditions, where careful checks and ongoing support really matter.
At the hospital, care often covers thyroid problems, including thyroid cancer such as papillary thyroid cancer and thyroid cancer more broadly, plus medullary thyroid carcinoma. There are also cases involving parathyroid hormone issues, like hyperparathyroidism.
Lea also works with patients who have genetic or inherited hormone conditions. That can include multiple endocrine neoplasia (MEN) syndromes, including MEN type 2, and other inherited disorders where hormones need close monitoring over time. Some patients may have issues linked to aromatase deficiency, and others may be managing complex rare conditions that affect how the body uses energy.
Diabetes care is another part of the picture, especially type 2 diabetes (T2D). This can involve looking at hormone-related drivers of blood sugar problems, spotting risks early, and helping people make sense of what changes to expect.
While the main focus is hormones, some referrals also come with heart-related concerns. In many cases, this means working alongside other teams when patients have heart failure, including heart failure with preserved ejection fraction (HFpEF), and conditions like cardiomyopathy. Mitral valve prolapse also appears in some patient pathways, where hormone balance can still be part of the wider health story.
At times, care may include people with movement or nerve-related conditions as well, such as Friedreich ataxia and hereditary ataxia. There can also be metabolic conditions like very long-chain acyl-CoA dehydrogenase (VLCAD) deficiency, which brings its own set of challenges and monitoring needs.
Across all of this, the aim is steady, practical support. Lea’s work focuses on getting the right tests, making sense of results, and helping patients and families plan next steps in a way that feels manageable.
