We understand that considering surgery or another medical treatment can be daunting, so we’ve compiled answers to some of our Frequently Asked Questions to try and help you navigate things.

To discuss your individual circumstances, schedule an appointment with a team member.

WEIGHT LOSS (BARIATRIC) SURGERY – GENERAL

When will my family know my surgery is finished?

Dr Balalis contacts all next of kin following surgery, and updates them on your progress. He also sees all patients daily (at least) until discharge.

Who can come and visit me at the hospital after weight loss surgery?

Hospital policy is ever-changing, and this is updated frequently on the hospital websites. The easiest way to stay up to date is to review the hospital website and to contact the hospital closer to your surgical date.

Do most people lose weight after weight loss (bariatric) surgery?

Yes, and they keep it off. Bariatric surgery is the only proven way to lose weight and keep it off. Weight regain is still possible however and a continued effort to maintain a healthy lifestyle is essential to long term results. We have a holistic team to provide patients with support for long term changes.

What does your BMI have to be to have weight loss surgery in Australia?

Current guidelines followed by Dr Balalis recommend a BMI from 30 with a medical condition related to obesity or a BMI of 35.

All patients wanting more information, should consult with Dr Balalis to discuss weight loss surgery and other options.

Is it my fault that I am obese?

No, it is not your fault. Obesity is a chronic disease, that results from a complex interaction between genetics and environment. Your genetics can determine how susceptible you are to weight gain and you can not change your genetics. Surgery can assist to improve lifestyle and health.

Can I use ibuprofen or other anti-inflammatories after weight loss surgery?

Not after a gastric bypass. After a sleeve gastrectomy, Ibuprofen or other anti-inflammatories are OK to use, as long as it is with a PPI (acid-suppression tablet). This is because non-steroidal medication after a gastric bypass can cause ulcerations with subsequent bleeding and perforation (hole in your bowel). There are alternatives for steroidals.

Is my weight loss surgery ‘keyhole’?

Yes – Dr Balalis does not perform open bariatric surgery. He performs laparoscopic or keyhole weight loss surgery, including all revision surgeries.

Does Dr Balalis perform a ‘re-sleeve’?

No – Dr Balalis does not believe in ‘re-sleeve’ operations and is happy to discuss this further. There are more proven and durable revision surgery options available.

What is the recovery time for weight loss surgery (gastric bypass or gastric sleeve)?

2 days in hospital – one night in ICU, and one night on the ward. People who work office jobs, can aim to be back at work after 2 weeks. If you have a more strenuous job, then this will mean more time off work.

When can I start to exercise?

6 weeks of no heavy lifting – no lifting more than 10kgs. Our exercise physiologist will tailor a plan suitable for your specific needs, to ensure you continue to exercise during this time, and into the future, for improved health and quality of life.

When can I start driving?

10-14 days following surgery is usually when you can start driving again. It is important that you are off pain medication, can slam on the brake in case of an emergency, and your insurance company are happy.

What weight loss can I expect?

Usually 65-75% excess weight loss (difference between healthy weight and current weight), over a 2-year period. The majority of this occurs in the first 12 months.

Do I need to take vitamins for life?

A range of multivitamin and mineral supplements are generally required following weight loss surgery. The type and number of supplements will depend on your surgery and results of ongoing blood tests to monitor your nutritional status.

Do I need regular bloods?

Yes, regular blood tests are needed in the first 2 years. It is important to keep on top of your blood monitoring to ensure the best result.

Do I need to come to my appointments?

Dr Balalis feels passionately about the holistic and supportive team that is all under one roof at 149 Ward Street North Adelaide. Their expertise and support is what provides patients with the care and knowhow needed for good outcomes. Please come to your appointments, and also use our online support!

Will I lose my hair?

Only a minority of patients lose their hair, and this is particularly in the first 6-12 months. The hair loss is temporary and associated with rapid weight loss. It is important to liaise with our dietitians and medical team to ensure vitamins, minerals and supplements are optimised during this period.

When can I fall pregnant after weight loss surgery?

Guidelines recommend 24 months after surgery as the ideal timeframe, however 12 months is a minimum recommended time frame. It is important to liaise with our experienced bariatric surgery team, as we need to monitor vitamins, minerals and supplements more closely.

GASTRIC SLEEVE SURGERY (SLEEVE GASTRECTOMY)

Will my Gastric Sleeve stretch?

Yes over time, but not to where it used to be.  Please read the article on Dr Balalis’ website regarding stretching, which is a normal process, and does not equal weight regain.

What is the recovery time for Gastric Sleeve surgery?

2 days in hospital – one night in ICU or HDU, and one night on the ward.  People who work office jobs, can aim to be back at work after 2 weeks.  If you have a more strenuous job, then this will mean more time off work.

Is a Gastric Sleeve better than a Gastric Bypass?

No – a Gastric Sleeve and Gastric Bypass are different.  There is no ‘best surgery’, only different surgeries, with different risks and benefits.  Dr Balalis will discuss the surgical options further during a consultation.

ENSDOSLEEVE PROCEDURE (ENDOSCOPIC SLEEVE GASTROPLASTY)

How long will recovery take after an Endosleeve procedure?

Since no incisions are made with an Endosleeve most patients can return to their normal activities within a few days. While recovery depends on each individual’s circumstances, it is recommended that you plan for at least three days of inactivity following the procedure.

Are there any diet restrictions following an Endosleeve procedure?

An Endosleeve is a restrictive procedure meaning it will limit the amount of food that you can eat. Life-long vitamin/mineral supplementation as well as protein supplementation is also necessary due to decreased intake of food as well as limited absorption of nutrients.

Our expert dieticians will prepare post-procedure nutrition plan for you and continue to monitor your progress as part of our post-procedure support service, Post-Care-Success.

Is the Endosleeve a permanent procedure?

An Endosleeve uses permanent stitches that do not dissolve; however, these can be removed at a later date if required.

It is possible for the stitches to break over time if under too much tension, however this does not necessarily lead to reversal of the Endosleeve or weight gain.

Endosleeve and pregnancy?

If you are planning to get pregnant in the future, this should be discussed with Dr Balalis at your initial consultation.

It is normally advised that patients avoid pregnancy for at least six months following an Endosleeve procedure.

Can I have an Endosleeve following a Gastric Bypass?

While an Endosleeve procedure is not suitable following a Gastric Bypass, it is possible to have a Transoral Outlet Reduction (TORe) using an overstitch device.

If you have previously had a Gastric Bypass and would like to discuss a Transoral Outlet Reduction, please request an appointment to discuss your options with Dr Balalis.

Can I have an Endosleeve following a Gastric Balloon?

Research has shown that people who’ve had a gastric balloon do less well following an Endosleeve in terms of weight loss.

If you have had a gastric balloon and feel like you need additional support, please request an appointment to discuss your options with Dr Balalis.

Can I have an Endosleeve following a Lap Band?

Research has shown that people who’ve had a Lap Band do less well following an Endosleeve in terms of weight loss.

If you have had a Lap Band and feel like you need additional support, please request an appointment to discuss your options with Dr Balalis.

ALLURION GASTRIC BALOON

Am I eligible for the Allurion Balloon?

To be considered for the Allurion Balloon:

No prior surgery to your stomach or oesophagus.

Over the age of 18

A BMI between 27 and 40

Are not currently pregnant or breastfeeding

Are prepared to make changes

Dr Balalis will also formally assess you for all contraindications in your initial consultation and discuss risks and benefits of the procedure. Dr Balalis is very passionate about helping patients improve their health. If you do not meet the criteria for the Allurion Gastric Balloon, but your BMI sits in the obese range, Dr Balalis encourages you to consider other clinically proven options.

What is the Allurion Balloon?

The Allurion Balloon (formerly the Elipse Balloon) is a soft balloon placed in your stomach. It is the first gastric balloon that requires no surgery, endoscopy, or anaesthesia for placement or removal. The balloon is placed during a brief 20-minute outpatient visit. After approximately 16 weeks, it empties and passes naturally.

How does the Allurion Balloon work?

The balloon takes up space in your stomach and induces weight loss by increasing satiety (fullness), delaying gastric emptying and reducing the amount of food eaten at each meal.

How much weight can be lost with Allurion Program?

After approximately 16 weeks of the Allurion Program, clinical studies have demonstrated that patients lose on average 10-15% of their body weight over the 4 months of the balloon.

What happens on placement day?

The patient swallows a capsule containing the deflated balloon along with a thin tube. Once the balloon is confirmed to be in your stomach via x-ray, the balloon is filled through the catheter with 550 ml of water. A second x-ray takes place to make sure the balloon is filled. The placement takes place during a 20-minute outpatient visit.

Is the balloon easy to swallow?

99.9% of patients are able to swallow the Allurion balloon. Dr Balalis has techniques to assist with this and can discuss this with you during your consultation.

What are the possible side-effects after balloon placement?

Some people experience nausea, abdominal cramping, and occasional vomiting after balloon placement. In most cases, these symptoms are well-controlled with the commonly used medications prescribed.

How long does it take to return to normal activities after balloon placement?

Most people return to normal activity within 2-3 days, however some people may experience longer side effects. It can be a good idea to book a few days off work afterwards just in case. Medications are prescribed to assist with the management of this.

How is the balloon removed?

After approximately 16 weeks inside your stomach, a time-activated release valve will open, allowing the balloon to empty and pass naturally through the gastrointestinal tract without the need for a removal procedure.

What are the dietary restrictions?

Following medical approval, there are no absolute dietary restrictions with the Allurion Programme. However, to maximise weight loss and comfort, our dieticians will make recommendations tailored to each patient. The Allurion Balloon must be used in conjunction with a nutrition plan.

What happens after the balloon has passed?

After the Allurion Balloon passes, the Allurion Program and the related support from your healthcare team continue for one month. At the end of the Allurion Programme, you should continue your healthy lifestyle habits.

Is the Allurion Program proven to be better than diet alone?

A recent clinical study has shown that, when coupled with a 16-week intensive lifestyle modification (nutrition and exercise modification), The Allurion Balloon leads to significant weight loss when compared with lifestyle modification alone.

What are the risks of the Allurion Gastric Balloon?

Nausea and vomiting in the first few days after placement.

Intolerance of 2-3%, which may need endoscopic removal [1].

The risk of the balloon itself are rare (less than 1%), and these include hyper inflation or obstruction which would require intervention to remove the balloon (such as an endoscopy). Dr Balalis is a specialist bariatric surgeon and able to perform this in the rare event of it occurring [1].

Over 60,000 + patients have been treated with the Allurion Balloon and serious adverse events have been reported in 0.34% of patients.
