Central Coast Weight Loss Surgery

22/12/2025

As many of my trusted patients already know, I have retired from surgical practice after many years caring for the Central Coast community. To ensure your care continues seamlessly, Dr Peter Hamer will be taking over my practice at 33 Etna Street, Gosford.

Peter and I share the same values: compassionate care, clear communication and a commitment to patient wellbeing. You’ll be in excellent hands with him.

Thank you for the trust you’ve placed in me over the years. I’m confident this transition will be smooth and supportive for every patient.

Hello everyone and valued patients.

After many fulfilling years caring for bariatric patients, the time has come for me to retire from surgical practice. Making this decision has not been easy, as my work has always been deeply meaningful to me. I have had the privilege of supporting thousands of patients through transformative journeys and I want to sincerely thank you for trusting me with your health.

As part of retiring, it was incredibly important to me that every patient continues to receive high-quality and compassionate care. For that reason, I have chosen Dr Peter Hamer to take over my practice and continue caring for my patients.

Many of you may already know Dr Hamer, as he has worked alongside me locally for many years. He is a highly experienced General, Upper Gastrointestinal and Bariatric Surgeon with extensive training across world-leading centres

What has always stood out about Peter is not only his technical expertise, but his genuine compassion, humility and patient-centred approach. His commitment to evidence-based care, minimally invasive techniques, and long-term patient support aligns closely with the approach I have always prioritised.

Dr Hamer consults from:

• 33 Etna Street, Gosford NSW 2250

• 18 Wiowera Road, Kanwal NSW 2259

📞 02 4380 8404

🌐 www.drpeterhamer.com.au

Your medical records will be transferred securely to ensure your care continues without interruption. If you need a follow-up appointment, review, second opinion or ongoing support with weight-loss surgery, Dr Hamer and his team will be ready to help.

As I enter retirement, I do so with gratitude and confidence, knowing that my patients are being left in excellent hands. Thank you, once again, for allowing me to be part of your health journey. It has truly been my honour.

Warmly,

Dr Ken Wong

Had a great morning catching up with Dr Craig Taylor, bariatric surgeon from the O Clinic in Sydney. We talked about bariatric surgery, life and coffee. Craig's experience and passion for weight loss surgery are inspiring. His facilities and programs for weight management were most impressive. Always good to exchange ideas with experienced colleagues so that we can provide better patient care.

Be careful if taking weight loss medications before surgery. Let the doctor know.

A London-based consultant plastic and cosmetic surgeon, has warned of a mistake those on weight loss jabs can make that could leave them 'choking to death' on the operation table.

Wowsers, two decades have passed by quickly. It has been a privilege and pleasure to be part of tens of thousands of health journeys.

BMI (body mass index) is no longer a reason to deny patients requiring bariatric surgery.

The ABC has previously reported cases of patients being turned away from essential surgeries based on BMI cut-offs.

The Global Commission on Clinical Obesity has put forward 18 criteria for diagnosing clinical obesity, moving away from the use of the Body Mass Index.

Combining medications with bariatric surgery may be more effective in the management of obesity for better long term outcomes.

Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are cost effective in the long term only when combined with bariatric surgery, according to a study, ‘Comparative cost-effectiveness analysis of bariatric surgery and GLP-1 receptor agonists for the management of obesity’, presented at the Am...

When the air con dies and it hits 30 degrees, sleeves must go on and the surgical team will lose weight too with a few liters of sweat

Latest data from the national bariatric surgery registry helps to answer the debate between gastric sleeve surgery vs bypass.

Bypass has three times the complication rate of sleeve. Weight loss is very similar over 4 years after surgery.

Always sad to read these stories.

A heartbroken husband has issued a horrifying warning after his wife tragically died just months into her weight loss journey.
