Choosing to pursue weight loss surgery is a significant step toward a healthier life, and it all starts with determining if you are a suitable candidate. Dr Peter Hamer and his weight loss surgery team are here to help you navigate this important decision.

Before moving forward, Dr Peter will carefully evaluate your medical history and current health status by considering key factors:

🔹Is your Body Mass Index (BMI) 35 or higher?
🔹Do you currently have Type 2 Diabetes or other signs of Metabolic Syndrome?
🔹Have you genuinely tried to lose weight and keep it off through non-surgical methods without long-term success?

If you answered yes to these questions, weight loss surgery might be the effective solution you need. Dr Hamer offers a comprehensive range of surgical options tailored to your specific needs. For consultations with Dr Hamer, book an appointment by calling (02) 4380 8404.

It's Gastro-Oesophageal Reflux Disease (GORD) Awareness Week—a condition affecting millions that is far more serious than "just heartburn."

Chronic reflux can significantly impact your quality of life and even pose serious health risks if ignored. Understanding GORD is the first step toward effective management and protection of your long-term health.

If you are experiencing regular symptoms, the best first step is to seek professional help by consulting your GP.

Use our established videoconference service to attend your crucial appointments with ease, right from your own smartphone, tablet, or computer.

For those living close to our rooms at 33 Etna Street in Gosford or 18 Wiowera Road in Kanwal, we still encourage you to attend in-person if possible, as patients often find that face-to-face consultations are more valuable.

For consultations or more information, feel free to reach out by calling (02) 4380 8404.

Excess sugar consumption is a major driver of weight gain and can significantly impact your long-term health. As we mark Sugar Awareness Week, it’s a crucial time to think about the 'hidden' sugars in your daily diet—and they don't always appear as 'sugar' on the ingredients list!

Sugar can be added in many forms (like dextrose, maltose, or syrups). Learning to identify these different names is a vital first step in controlling your intake for a healthier life.

We focus on more than just weight loss; we aim for a sustainable, healthier lifestyle. Understanding and controlling your sugar intake is a vital step toward achieving lasting results, whether through surgical weight loss options or tailored dietary plans with our dietician, Sarah.

For consultations or more information about weight loss surgery, or to book an appointment with our dietitian, please call (02) 4380 8404.

This World Diabetes Day, I want to highlight an undeniable fact: excess weight and Type 2 Diabetes (T2D) are deeply connected, driven by issues with the body’s metabolism. Weight loss surgery is a powerful tool to interrupt this cycle and drive T2D into remission.

For some people who have had type 2 diabetes for less than 7 years, surgery is likely to cause diabetic remission and normalise blood sugar levels.

If you have had diabetes for longer than 7 years, sometimes surgery can cause diabetic remission, but is more likely to lead to decreased need for tablets or insulin.

Want to explore if you're suitable candidate for weight loss surgery? Call us at (02) 4380 8404 for a consultation with Dr Hamer.

You can also book an appointment with our Dietitian, Sarah, with or without a GP referral and no need to be a patient of Dr Hamer.

On Remembrance Day, we join the nation in a moment of sincere reflection and gratitude.

To the brave men and women who have served and sacrificed for our freedom—thank you. As a surgeon, I am reminded of the fragility of life and the immense courage it takes to protect it.

Lest We Forget.

Sarah is our in-house dietitian, and is an invaluable part of Dr Peter Hamer's care team.

She specialises in providing essential, evidence-based nutritional guidance for patients undergoing surgery—including weight loss, reflux, and cancer surgery—ensuring every individual receives a tailored dietary plan for optimal recovery and long-term health.

Sarah is also available for general dietary issues with or without a GP referral. This means you can access professional, expert nutritional advice—like managing diabetes, high cholesterol, or food intolerances—without a surgical consult or being a current patient of Dr Hamer!

To book an appointment with Sarah, please call us on (02) 4380 8404.

November is Stomach Cancer Awareness Month, also known as Gastric Cancer Awareness Month, a crucial time to spotlight a disease that is often diagnosed too late.

Stomach cancer (or gastric cancer) can be a quiet disease. Its early symptoms are often mistaken for common indigestion or reflux.

If you experience any of these symptoms, please do not dismiss it. A thorough evaluation can make all the difference. If you have a family history or are concerned about your personal risk, consult with your GP. Early diagnosis drastically improves treatment outcomes.

For consultations with Dr Peter Hamer, book an appointment by calling (02) 4380 8404.

If you've developed a hernia that you believe is the result of your work duties, you may be able to have your hernia fixed through Workers Compensation (in NSW, this is managed by icare).

Fixing your work-related hernia through this system allows you to access the private hospital system, often resulting in much shorter waiting times compared to the public system.

Dr Peter Hamer is happy to perform your hernia repair under the workers compensation scheme. However, this process does require prior approval from icare. Remember to report any work injury to your employer immediately—this is the first step!

Did you know the potential benefits of weight loss surgery go far beyond the scale? Many patients report a significant improvement in their sleep quality and a potential reduction in snoring.

This improvement often relates to Obstructive Sleep Apnoea (OSA). For people with severe obesity, excess weight around the airway can cause breathing to repeatedly pause at night, leading to interrupted sleep, chronic fatigue, and long-term health risks.

Weight loss surgery is a recognised strategy in managing OSA. As substantial weight loss is achieved, the physical pressure on the airway can be relieved. Research indicates that surgery is associated with a high rate of significant improvement or resolution of OSA symptoms within the first year.

If you are struggling with sleep issues or fatigue, explore if weight loss surgery might be the solution for you. Book a consultation with Dr Peter Hamer today by calling (02) 4380 8404.

Gallbladder removal (cholecystectomy) is one of the most common keyhole operations we perform, and it's remarkably safe and effective.

The procedure involves making 4 to 5 small incisions in your belly wall. We detach the gallbladder from the bile duct and liver, then remove it. Sometimes, we perform an x-ray test (cholangiogram) during the surgery to ensure no gallstones have moved into the bile duct.

Most patients go home the same day or after just one night in the hospital.

Have questions about your gallstones or keyhole surgery? Book a consultation with Dr Peter Hamer today by calling (02) 4380 8404.
