​Overweight and obesity have become serious public health issues worldwide. Research has shown that being overweight or obese increases one’s risk of developing many chronic illnesses such as diabetes and cardiac diseases. Adopting a healthy lifestyle to achieve meaningful weight loss can significantly reduce the risk of developing these diseases. The Singapore General Hospital (SGH) Obesity Centre was formed to bring together healthcare professionals across disciplines to cater to these needs.


The SGH Obesity Centre uses evidence-based integrated approaches to help people with obesity lead a healthier lifestyle and, in the process, achieve sustained weight loss, weight maintenance and improved health for themselves.

The Centre’s multidisciplinary team consists of endocrinologists, surgeons, gastroenterologists, dietitians, physiotherapists, psychologists, pharmacists, specialty nurses and clinical coordinators – all of whom play an important role in holistic patient care.


  • Medical Weight Loss
  • Metabolic Bariatric Surgery
  • Endoscopic Bariatric Procedures
  • Allied Health / Lifestyle Interventions
  • Bariatric Support Group


We welcome the opportunity to co-manage patients with general practitioners (GPs), who remain central to their care.

It is common for patients to see the dietitians, physiotherapists and psychologists at the Centre, while continuing to follow up with their GPs for chronic medical conditions. Patients who have their own GP may also only see the Centre’s endocrinologists once or twice yearly, to check on their weight loss progress.
