Ann I. Mccormack is an Endocrinologist based at St. Vincent's Clinical School in Sydney, NSW 2052, Australia. She looks after people with hormone-related health issues. This can include problems with the pituitary gland, the hypothalamus, and other parts of the body that help control growth, energy, and metabolism.
Many of the patients she sees have long-term conditions that can feel confusing at first. Hormone levels can affect how you feel day to day, not just test results. In many cases, her work helps people understand what is going on and what options may help.
Her clinical care covers a wide range of endocrine problems. This includes diabetes insipidus (DI), SIADH, and different forms of hormone imbalance such as Cushing’s disease and Cushing’s syndrome. She also sees people for pituitary and brain related conditions like prolactinoma, acromegaly, hypopituitarism, and hypothyroidism. At times, this includes tumours such as pituitary tumours, craniopharyngioma, and other brain tumour conditions that can affect hormone control.
She also works with parathyroid and calcium-related issues. That can mean looking after hyperparathyroidism, familial isolated hyperparathyroidism, and parathyroid adenoma. In some cases, hormone problems can link in with other conditions like multiple endocrine neoplasia (including MEN1).
Because endocrine conditions can be linked to other medical issues, her approach is practical and focused on the whole picture. For example, she may coordinate care when someone has ongoing symptoms like headaches, or when there are complications such as cerebrospinal fluid leak and related skull base concerns. Her scope also includes support around procedures used for pituitary and related areas, such as endoscopic transnasal transsphenoidal surgery.
Ann’s education and training are in medicine with specialist focus on endocrine disorders and hormone-related diagnosis. Over time, she keeps up with changing care approaches for conditions that affect the pituitary, thyroid, adrenal hormones, and calcium balance. She also pays attention to research and new clinical findings where they are relevant to day-to-day care.
If you’re dealing with hormone problems, it can help to get clear answers about what might be causing symptoms. Ann aims to do that in a calm, straightforward way, using tests, scans, and clinical history to guide next steps.
