New research highlights importance of long-term support after bariatric surgery

Led by senior clinical dietitian Sally Badorrek at Nepean Hospital, the study explored the experiences of both patients and general practitioners (GPs) across metropolitan and regional settings, and public and private healthcare pathways.

Bariatric surgery is widely recognised as one of the most effective treatments for obesity, delivering sustained weight loss and improvements in conditions such as diabetes, high blood pressure and sleep apnoea. The study builds on this by examining what supports patients need beyond the surgical phase.

Findings show that while many patients experience significant health and quality of life improvements, ongoing care plays a key role in maintaining these outcomes over time.

“Bariatric surgery is effective, but patients often need support well beyond the early post-operative period. Coordinated, long-term care is key to maintaining outcomes,” says Sally.

The study captured a wide range of patient experiences, with many describing positive outcomes including increased energy, improved mobility, and greater confidence. Both patients and GPs also emphasised that success extends beyond weight loss alone, encompassing overall health, wellbeing, and quality of life.

Importantly, the research highlights the role of primary care in supporting patients over the long term. GPs were identified as central to ongoing care, particularly as patients transition from surgical services back into the community.

“GPs play a central role in long-term follow-up, but many report unclear responsibilities. Stronger shared-care pathways would help improve continuity.”

The study also reinforces the importance of multidisciplinary support, including access to dietitians, psychologists, and other allied health professionals, particularly as patients adjust to changes in eating patterns, lifestyle, and overall health following surgery.

“Recovery extends beyond physical changes after surgery. Ongoing nutritional, medical and psychological support is often needed,” explains Sally.

Patients highlighted the value of regular check-ins, clear information, and supportive communication from healthcare providers. However, many also described having to coordinate their own follow-up care, particularly when services were not well connected.

“Patients often end up driving their own follow-up care. This can be difficult when services are fragmented.”

The research also points to opportunities to further strengthen care through clear communication between healthcare providers, structured follow-up approaches, and ongoing patient education.

“A more connected model of care, similar to the Family Metabolic Health Service at Nepean Hospital, is needed across hospital, primary care and community services. This would improve continuity and long-term outcomes.”

The findings support a continued focus on integrated, multidisciplinary models of care that extend beyond the surgical phase and into long-term health management.
