About of Stan B. Sidhu

Stan B. Sidhu is an Endocrinologist based in Sydney, NSW, Australia. He looks after people with hormone-related health issues, where the body’s glands and signals don’t quite line up.


Endocrine problems can be hard to explain because they affect lots of different parts of the body. Over time, hormone imbalances can show up as tiredness, weight change, feeling “off”, blood test changes, or symptoms that come and go. In many cases, the goal is to find the cause, not just treat the results.


Stan works with patients who have thyroid and parathyroid conditions. This can include things like thyroid nodules, thyroid inflammation such as Hashimoto’s thyroiditis, and gland hormone problems like hyperparathyroidism or hypoparathyroidism. He also helps people after surgery, including parathyroidectomy or thyroidectomy, with follow-up care and ongoing monitoring.


He also cares for people dealing with more complex hormone disorders. This includes adrenal gland conditions such as hyperaldosteronism, adrenal gland adenoma, and adrenal hormone tumours. At times, patients need help with rarer conditions linked to hormone growth patterns, including multiple endocrine neoplasia type 1 and type 2, plus related cancers. He can also manage endocrine issues seen in congenital adrenal hyperplasia (CAH).


Some patients come in with concerns about endocrine cancers. These may include thyroid cancers such as papillary, follicular, and anaplastic thyroid cancer, along with medullary thyroid carcinoma, parathyroid cancer, and neuroendocrine tumours. For others, the focus may be adrenal cancer or conditions linked to unusual hormone swings, like pheochromocytoma.


Stan also looks at hormone issues that connect with other body systems. For example, chronic kidney disease and end-stage renal disease can go hand-in-hand with hormone and salt balance changes, and that can affect things like acid balance in the body. He also supports patients with intersex-related endocrine needs, where hormone management is part of long-term care.


While he may not be the first person you see, his role is to help bring clarity. He uses blood tests and clinical history to guide next steps, and he works alongside other health professionals to support safe, sensible treatment plans.


He keeps up with current care approaches through ongoing learning and guideline updates. If a patient is ever looking at clinical trials, Stan can help explain what the options may be and whether research care is relevant to their situation.

Frequently Asked Questions

Which conditions do you treat as an endocrinologist?
I focus on thyroid and parathyroid problems, adrenal disorders, metabolic issues, and related conditions. My listed service areas include thyroid cancer, thyroid nodules, Hashimoto's thyroiditis, hyperparathyroidism, parathyroid disease, pheochromocytoma, and various endocrine cancers.
What thyroid and parathyroid conditions do you manage?
I treat thyroid cancers (including papillary, follicular, medullary, and anaplastic), thyroid nodules, Hashimoto’s thyroiditis, hyperparathyroidism, parathyroid adenomas and cancers, parathyroid hyperplasia, and related gland disorders.
Do you treat adrenal and kidney related conditions?
Yes. My practice covers adrenal diseases such as adrenal cancer and pheochromocytoma, and kidney-related concerns including chronic kidney disease and end-stage renal disease when they relate to endocrine issues.
Can you help with multiple endocrine neoplasia and other genetic syndromes?
I work with conditions like Multiple Endocrine Neoplasia types 1 and 2, and other endocrine-related genetic concerns as part of comprehensive care.
How do I arrange an appointment?
If you need endocrine care in Sydney, you can book an appointment to see me. We’ll discuss your health concerns and plan testing or treatment as needed.
What should I bring to my first visit?
Bring any relevant medical records, previous test results, imaging, and a list of current medications. If you have specific concerns about cancer or thyroid disease, note them so we can cover them during your visit.
