Yi Y. Wang is an Endocrinologist based at St Vincent's Hospital Melbourne in Melbourne, VIC, Australia.
In day-to-day work, Dr Wang looks after people with hormone problems, especially those that involve the pituitary gland and the area around it. This can include issues like acromegaly, hypopituitarism, and diabetes insipidus (DI). At times, hormone imbalances can also show up as low sodium levels, and that can feel quite worrying when it’s new.
Dr Wang also works across care that involves the brain structures connected to hormone control. Services listed include endoscopic approaches such as endoscopic transnasal transsphenoidal surgery. This is used for conditions like pituitary tumours and hypothalamic tumours, as well as some related brain tumours. It can also be considered for things like a cerebrospinal fluid (CSF) leak and Rathke cleft cysts. In many cases, this kind of work needs close teamwork with other specialists, because hormone health and brain health are linked.
There are other conditions also mentioned in the scope of care, including Sheehan syndrome and headaches that come along with pituitary problems. Some people are referred after scans show changes such as arachnoid cysts. Others may be dealing with rarer problems that affect hormone balance or nearby structures, such as ganglioneuroma or arachnoid cyst-related symptoms. Over time, the goal is to make things steady again, both with treatment and with follow-up.
Dr Wang’s hospital-based work also lists procedures and support that go beyond hormones alone, like endoscopy and spinal fusion. That wider set of services can matter when someone has more than one health issue happening at the same time. If you’re coming in because of endocrine symptoms, it helps that the focus stays practical: understanding what’s driving the hormone change, managing it properly, and keeping an eye on how you’re going from one step to the next.
