Frequently Asked Questions


There is no ‘one size fits all’ operation when considering metabolic surgery. Each surgery has its advantages and disadvantages, as well as slightly different risk profiles. What is ‘best’ for you, may not be best for your neighbour. At your initial consultation we will discuss your individual circumstances – (e.g. your BMI, goals and medical history) as well as the pro’s and con’s of the different surgeries. I have outlined a few points below addressing some pertinent considerations.

It is important to remember that surgery (irrespective of which one) is an aid to help you achieve your goals. Metabolic surgery offers powerful neuro-hormonal effects to suppress your appetite, alter your food absorption and metabolism as well as significantly reduce your stomach size. Surgery will not, however, force you to make the appropriate food and lifestyle choices. That decision is up to you. Our program incorporates dietitian and psychology support to help you understand and adjust to the changes you should be implementing.

Things to consider:
Do you have gastro-oesophageal reflux disease?

Following a sleeve gastrectomy (LSG) the stomach has a higher internal pressure compared to a bypassed stomach. This can promote gastro-oesophageal reflux disease. It is preferable to avoid a sleeve gastrectomy if you have oesophagitis or Barrett’s oesophagus. On the other hand the Roux-en-Y Gastric Bypass (RYGB) is the ‘gold standard’ anti-reflux operation. The One Anastomosis Gastric Bypass (OAGB) is also an anti-reflux operation.

Are you a smoker?

Smokers are prone to developing an anastomotic ulcer following a RYGB or OAGB. The risk of this is very high and I do not offer gastric bypasses to smokers for this reason.

Will I develop an internal hernia?

Internal hernias can develop following a gastric bypass. The RYGB has two anastomosis and there is a lifetime risk of developing a hernia and small bowel obstruction. The OAGB (with one anastomosis!) minimises this risk. During the sleeve gastrectomy the small bowel position is not adjusted and thus there is no risk of an internal hernia.

Are you female and planning a future pregnancy?

Our Practice recommends allowing for a minimum of 18 months after your surgery to fall pregnant. The American College of Obstetricians and Gynaecologists advise: ‘ a women should wait 12-24 months before conceiving so that the foetus is not affected by rapid maternal weight loss, and so that the patient can achieve her weight loss goals.

Are there any situations when I should not undergo a gastric bypass?

In general, if you suffer from Crohn’s disease, faecal incontinence or significant osteoporosis then a gastric bypass would not be recommended. In these circumstances, a sleeve gastrectomy would be the preferable option instead.

Where will my operation be performed?

All operations are performed at the Sunshine Coast University Private Hospital (SCUPH). SCUPH is a Level 6 accredited hospital with a 6 bed Intensive Care Unit.
All ward beds are individual private rooms with ensuites. The SCUPH team – ranging from the surgical scrub nurses to the recovery and ward staff – are experienced with bariatric surgery and patients.

Will I see Dr Askew after surgery?

Dr Askew is a thorough and meticulous surgeon – both during surgery and also in your aftercare. Dr Askew attends the hospital daily and will be personally keeping a close eye on your recovery.
