About Me

Dr Clement Tsang is a specialist weight loss surgeon who has sub-specialised training in modern weight loss procedures. He has focused his clinical practice on advanced laparoscopic (keyhole) surgery. He is an Australian-trained surgeon having completed his medical education and surgical training in Australia. He also undertook additional sub-specialised training in Hong Kong and the United States. Dr Tsang holds a Master of Surgery Degree (Upper-GI Surgery) from the University of Sydney with specialisation in the management of gastrointestinal reflux disease, hiatal hernia surgery and the metabolic impact of surgery.

He now focused his clinical and surgical practice into upper-gi and bariatric surgery to provide greater sub-specialisation for his patients. Dr Tsang currently manages more than 3,500+ patients in his clinic and has performed more than 5,000+ weight loss procedures, making him one of the most experienced in total case volume in Sydney. He is the Clinical Director of the Keyhole and Obesity Surgery Centre with a multidisciplinary team comprised of a psychologist, dietitian and weight loss physician, whose goal is to help you achieving the maximum weight loss.

Dr Tsang provides the full range of obesity surgery procedures, including gastric band, sleeve gastrectomy, revision weight loss surgery, gastric balloon procedure and gastric bypass. The majority of his operations are performed with minimally invasive laparoscopic techniques which result in less pain, early discharge, early return to work and better cosmetic results. He has a reputation for performing extremely safe surgery with a very low complication rate and a zero mortality rate.
