Marc P. Sim is an endocrinologist based in Joondalup, Perth. You can find his practice at 270 Joondalup Drive, Joondalup WA 6027. Endocrinology is about hormones and the way they affect the whole body, from blood sugar to weight and bone health.
Marc looks after people with long-term metabolic and hormone-related conditions, especially type 2 diabetes and metabolic syndrome. That often includes issues like abdominal obesity, ongoing weight concerns, and problems with blood pressure. In many cases, the goal is to get things steady and help prevent complications over time.
He also helps with concerns that can link back to hormone and body chemistry changes, including osteoporosis and frail bones. Pain and mobility problems can come along with that, and at times people may have acute pain or fractures that need careful follow-up. There are also situations where blood-related issues like anaemia, iron deficiency anaemia, and haemolysis are part of the overall picture, so the approach can be more than just one symptom at a time.
Some patients come in with heart and blood vessel risk concerns too, including atherosclerosis and hypertension. Others may be dealing with slower, broader health changes such as dementia. These are tough, and treatment plans usually focus on practical steps that fit the person’s daily life, not just test results.
Over time, Marc brings experience in managing complex, connected health problems. His work often involves coordinating care with other health professionals so treatment is consistent, and so people understand what matters most right now. He keeps an eye on how new findings can support day-to-day decisions, but without making things complicated.
Education details and any formal research or clinical trials are not listed here. If you’d like to know what specific training or research Marc has done, it’s best to ask the clinic directly when you book.
