Catherine S. Choong is an endocrinologist based in Nedlands, Western Australia. She works at the Department of Haematology and Oncology, 5 Hospital Ave, Nedlands WA 6009. If you’re dealing with hormone problems, growth issues, or changes in energy and sleep, her care is aimed at sorting out what’s going on and helping you find a clear next step.
Endocrinology can touch lots of parts of life. Catherine looks after people who need help with growth hormone and growth-related conditions, including growth hormone deficiency, short stature (growth disorders), and conditions like gigantism and acromegaly. She also supports patients with syndromes where hormones and growth don’t follow the usual pattern.
Many referrals are for the pituitary or hypothalamus side of the hormone system. That can include pituitary tumour, hypothalamic tumour, and related issues such as hypopituitarism, plus things like Sheehan syndrome. At times, hormone problems can show up in surprising ways, so it helps to have someone who can connect the dots between symptoms and hormone levels.
Hormones also affect blood sugar and body balance. Catherine cares for people with problems like congenital hyperinsulinism, low blood sugar, and hormone-related hormone replacement needs (HRT). She also sees cases involving high potassium, low sodium, renal tubular acidosis, and pseudohypoaldosteronism types 1 and 2. For some people, those lab changes can link to feeling unwell, tired, or just “not right”, and working out the cause matters.
Sleep and daily energy are another important area. Catherine works with people who have central sleep apnea, excessive daytime sleepiness, and drowsiness. Some conditions can affect how alert someone feels during the day, which can really impact school, work, and family life.
There are also rarer hormone and growth-related conditions she manages, such as Turner syndrome, Prader-Willi syndrome, Russell-Silver dwarfism, Swyer syndrome, and intersex conditions. She also looks after patients with certain hormone-making or hormone-related tumours, including Sertoli-Leydig cell tumours, Leydig cell tumours, testicular cancer, and brain tumour. Over time, she focuses on practical care and steady follow-up, because hormone conditions often need ongoing monitoring.
