About of John M. Wentworth

John M. Wentworth is an endocrinologist based in Melbourne, working from 99 Commercial Road, Melbourne, VIC 3004, Australia. His focus is on hormone-related health issues, especially problems that affect blood sugar, weight, and the way the body manages water.


For many people, endocrine care is about getting control back. John works with adults and families dealing with type 1 diabetes (T1D) and type 2 diabetes (T2D). He also looks after people with obesity and abdominal weight gain, including metabolic syndrome, where blood sugar, cholesterol, and blood pressure can all be out of balance at the same time.


Some cases are more urgent too. At times, he supports patients who have had diabetic ketoacidosis, helping them understand what happened and what steps can reduce the risk next time. He also treats diabetes insipidus (DI), including neurohypophyseal diabetes insipidus, which can cause strong thirst and frequent urination. Getting the right plan here can make day-to-day life feel much more manageable.


Care doesn’t only happen in the consulting room. John also provides endoscopy as part of his broader service approach. Depending on the situation, this can be used to investigate certain health concerns and guide next steps. It’s often about taking a practical route—checking what needs checking, then working out a plan that fits.


Over time, his work has centred on spotting what’s driving symptoms, then connecting the dots between hormones, metabolism, and everyday habits. In many cases, that means careful monitoring and clear advice that patients can actually use. At times, treatment involves adjusting medicines and reviewing targets, especially when numbers change or symptoms don’t match what someone expects.


John’s education is in medicine and endocrine training, with a strong focus on modern diabetes and hormone care. He keeps up with new guidance and treatment options, including what’s coming through from ongoing research, so care stays up to date. If clinical trials are relevant for someone’s situation, this is discussed in a straightforward way, focused on what would help and what the trade-offs might be.


If you’re looking for steady, down-to-earth endocrine support in Melbourne, John M. Wentworth provides care for common and complex hormone and metabolic conditions, with an emphasis on practical next steps and real-world follow-up.
