Sarah J. Glastras is an endocrinologist based at Royal North Shore Hospital in St Leonards, NSW, Australia.
Endocrinology is the area of medicine that deals with hormones and how they affect the whole body. Sarah looks after people when hormone-related health issues affect blood sugar, growth, metabolism, and other important body systems.
In day-to-day care, her patients may include people living with type 1 diabetes and type 2 diabetes. She also works with families dealing with gestational diabetes during pregnancy. Pregnancy and blood sugar can be tricky, and getting the plan right early can make a real difference.
Sarah also supports newborns and infants where blood sugar is low. This can happen in the first days of life, and it needs careful monitoring. She looks after situations like newborn low blood sugar and infant hyperglycaemia, where the body’s sugar levels can shift quickly.
Metabolic conditions are a big part of her work too. That includes obesity, metabolic syndrome, and non-alcoholic fatty liver disease. At times these conditions travel together, so it’s common for patients to need a clear, steady approach that covers lifestyle changes, regular checks, and hormone or sugar management.
She also manages people with low blood sugar more broadly, not just in newborns. When sugar levels keep dropping, it can affect energy, mood, and safety, so assessment and follow-up matter.
Sarah’s work goes beyond diabetes. She cares for people with conditions like medullary thyroid carcinoma and helps with longer-term planning around hormone and cancer-related follow-up. She also works with people affected by Wilson disease, a condition that affects how the body handles copper.
Some endocrine issues develop slowly, and others show up suddenly. Over time, Sarah aims to keep things practical and understandable, so patients know what’s happening and what the next steps are. Clear communication is part of good care, especially when there are different moving parts across blood sugar, weight, and overall health.
If you’re looking for an endocrinologist at Royal North Shore Hospital, Sarah J. Glastras is a local option for hormone-related care, including diabetes, pregnancy-related blood sugar problems, infant and newborn blood sugar concerns, and several other endocrine and metabolic conditions.
