Charmaine S. Tam is a Bariatric Surgeon based in Sydney, NSW, Australia. Her work focuses on helping people manage weight and the health problems that can come with it. This can include people who’ve tried diet and lifestyle changes, but still struggle to get lasting results.
In clinic and in theatre, Charmaine looks after patients who are dealing with obesity and weight-related conditions. Many people she sees also live with Type 2 Diabetes (T2D). At times, weight gain can make blood sugar harder to control, and that’s where bariatric surgery may be an option people consider. She also helps people understand what different procedures involve and what recovery can look like in real life, not just on paper.
Charmaine performs common bariatric operations, including sleeve gastrectomy and gastric bypass. She may also be involved in other gastric procedures when they fit a person’s situation. The goal is usually to support healthier eating patterns, improve metabolic health, and make it easier to manage diabetes over time. For many patients, it’s not only about weight. It’s about energy, day-to-day comfort, and feeling more in control of health.
Her care also reaches beyond weight, where relevant. She treats ovarian cysts and looks after people with ovarian overproduction of androgens, as well as Polycystic Ovary Syndrome (PCOS). These hormone and ovarian issues can affect periods, skin changes, and overall wellbeing. In many cases, weight and hormones are linked, so treatment plans often need to be thought about together, with clear next steps.
Charmaine stays grounded in practical care and works within the usual surgical standards and current clinical guidelines. She keeps an eye on what’s changing in treatment approaches, so decisions are based on good evidence and what matters for patient outcomes. She does not focus on listing research or clinical trial details as a main part of her practice, but ongoing learning and careful follow-up are part of how she works.
