Weight regain after bariatric surgery doesn’t mean the surgery failed, and it doesn’t mean you failed either.

Some regain from your lowest post-surgical weight is common and expected. Obesity is a chronic biological disease, not a single event that surgery switches off forever. Regain can come from a number of places: shifts in appetite biology, changes in medication, nutrition patterns, reduced activity, or the anatomy of the original operation itself.

If regain is significant, the right next step isn’t automatically another operation. It starts with an assessment: reviewing what the original surgery involved, how weight and symptoms have changed over time, and what your current anatomy looks like. That process is what identifies the actual cause, and from there, treatment might mean renewed dietetic support, a medication option, or in selected cases, revisional surgery. Surgery is a possible outcome of that assessment, not the starting point.

If weight has returned and you’ve been carrying some shame about it, that’s a common experience, and it’s not a fair one. The more useful question isn’t “did I fail,” it’s “what’s changed, and what can be done about it.”

Self-referrals are welcome. A GP referral isn’t required to arrange an assessment.

Travelling through Croatia, I have found myself noticing the extraordinary old stone walls and imagining the messages they could carry.

This is the one I would leave:

“They call it cheating.
We’re treating the biology.”

Bariatric surgery is not a shortcut or a failure of willpower. It is an evidence-based treatment for a chronic, complex disease, supported by nutrition, psychological care and long-term follow-up.

Different surroundings. Same message.

Weight loss surgery patients often arrive at their first assessment already apologising. They have usually spent two decades being told their weight was a discipline problem, and they believed it.

I have sat across from hundreds of people who were certain they had failed. Almost none of them had. What they had done was lose weight repeatedly, then run into a hormonal response that made regain close to inevitable, and then blame themselves for a mechanism nobody had ever explained to them.

The information was available. It just wasn’t given to them. That is not the same thing as a personal failing, and the difference matters, because people who understand what they are actually up against make better decisions about treatment than people who are busy being ashamed.

If you have been carrying that blame, you can put it down. It was never yours.

Send this to someone who has been apologising for years.

Lipoedema is a chronic fat tissue disorder that affects women almost exclusively, and it is routinely mistaken for obesity or simple weight gain. It causes symmetrical, tender fat deposition in the legs and sometimes the arms, sparing the hands and feet, and it typically appears or worsens at puberty, pregnancy or menopause.

The reason it matters in an obesity clinic is that the two conditions frequently coexist, and the treatment conversation is different. Weight loss reduces leg volume in these women, but it does not reliably resolve the pain or the disproportion. Bariatric surgery is adjunctive here, not the primary treatment. Lipoedema-specific liposuction is the disease-directed option and it is not publicly funded in New Zealand.

A word of caution on the other side of this. Lipoedema is discussed widely online now, and self-diagnosis has become common. Prevalence figures quoted as one in nine women have no solid epidemiological basis. Not every woman with heavy legs has lipoedema, and the label carries real consequences for what treatment gets offered. That is a conversation for a clinical assessment, not a checklist.

This isn’t a movie review.

It is a reminder that willpower was never the only character in the story.

Body weight is influenced by multiple, interacting biological and environmental factors:

Hormones can affect hunger and fullness.
Sleep can alter appetite signalling and energy.
Some medications can influence weight.
Stress can affect eating patterns, recovery and sleep.
Metabolism can adapt when energy intake falls.

That is why effective obesity treatment is rarely about simply “trying harder”. Depending on the individual, care may include nutrition, movement, sleep support, psychological support, weight-loss medication, bariatric surgery, or a combination of approaches.

Dunner stunner: City tops quality of life survey again

Weight loss surgery is not the only pathway at Southern Weight Loss, and it is not the right pathway for everyone. Two people can book the same assessment in Dunedin and leave with completely different plans.

One may go on to a sleeve or a bypass. Another may start medical treatment and never need an operation at all. That decision is made with the person in front of me, not handed to them.

What does not change is the structure underneath it. Every patient sees a dietitian and a psychologist as part of the assessment. Every surgical patient is followed for two full years, at one, four, eight, twelve, eighteen and twenty four months. No GP referral is needed to get started.

The plan is built around the person. The care behind it stays the same.

Weight loss surgery in Dunedin does not start with me telling someone which operation to have. It starts with a conversation about what each option actually costs the person having it.

There is usually an option the evidence favours. For reflux, for diabetes, for a particular starting point, the data leans somewhere, and I will always say where it leans. That is my job.

But the evidence cannot tell me how permanence feels to the person in the chair. It cannot weigh what changing their anatomy means to them, or what they are willing to trade for it, or what they are not. That part only they know, and it belongs in the decision just as much as the numbers do.

So the conversation in my clinic is not “here is what you should have.” It is here is what the evidence favours, here is what it costs, here is what the alternatives give up, here is what happens if nothing changes for now. Then they decide.

Not every preference gets honoured. If an option would cause harm, it is not on the table, and I say plainly why. The compromise sits inside the safe range, never outside it. That is the line, and it does not move.

But inside that range there is more room than most people are told. A sleeve when the numbers lean slightly toward a bypass. Medication first, with surgery still on the table later. Waiting six months because the timing is wrong at home. These are not failures of the process. They are the process working.

An unbiased consultation is not one where the surgeon has no opinion. It is one where the patient hears that opinion and still gets to choose.
