Bariatric and
General Surgeon

So What Should You Expect?

To prepare for surgery you will be required to be on a very low-calorie diet for two weeks prior to your surgery date. This includes using Optifast (or similar product) meal replacements as well as drinking plenty of water and eating plenty of ‘free’ vegetables. Free vegetables contain a decent amount of fibre per carbohydrate along with vitamins and minerals.

The purpose of this phase is to:

  • Reduce the size of your liver and decrease fat around your abdomen to allow easier access to the stomach during surgery
  • A reduction in any pre-existing metabolic abnormalities (e.g. hypertension, high blood glucose levels, high blood cholesterol)
  • Increase confidence that you will be able to comply with the post-operative dietary restriction

In the long term you should expect:

  • Reduced portion sizes
  • Good quality food with an emphasis on ensuring adequate protein
  • Daily supplementation with multivitamins and other nutrients as individually prescribed by the dietitian
  • Regular meals and snacks
  • Separation of food and fluid
  • That some foods which you eat regularly now may not be well tolerated

Our highly skilled dietitians have extensive bariatric surgery knowledge and are committed to working with you to support you through your surgical experience and into the future.

Dietitian appointments are usually scheduled for 10-14 days after surgery to upgrade your liquid diet to solid foods. Soon after, a soft and semi-solid diet will start, followed by a full bariatric diet. It is recommended that patients have five to six small meals a day. Regular sips of water are required to prevent dehydration since the consumption of large amounts of water in very short periods is not possible after bariatric surgery. Additional appointments and exercise consultations may be of benefit and can be arranged privately. Private health and/or Medicare rebates for these visits may be available.

Implications of
Bariatric Surgery

After any weight loss operation deficiencies particularly of iron, protein, calcium, micronutrients and different vitamins are possible. Therefore regular blood tests are required and sometimes an intramuscular vitamin B12 injection or iron infusion might be necessary. In most patients, these deficiencies are easily preventable by following the diet recommendations and taking daily multivitamin tablets.


Pregnancy must be avoided 24 months after weight loss surgery.

Smoking can promote inflammation of the stomach, which can lead to a gastric ulcer. Therefore, smoking should be avoided.

Sometimes loose bowel motions are possible and may require oral medication. Also reported are changes to the taste of food and sometimes reversible loss of hair.

Weight regain can occur after all types of bariatric surgery. Up to a certain level this is expected since the body adapts after surgery and becomes more efficient with food. If over time an increasing volume of food is consumed, the sleeve will enlarge causing the procedure to lose its effectiveness. A stretching of the gastric pouch, when overeating has also been reported after gastric bypass. Similar to a SG, a Minimizer gastric ring can be placed around the upper part of the gastric pouch during bypass surgery to prevent stretching some years down the line. Regular attention to weight gain and consultation with a dietician is necessary to minimise this possibility.

After any gastric bypass surgery, the anatomy has been changed due to the transection of the upper part of the stomach to create the pouch. Therefore the distal stomach cannot be entered with an endoscope (gastroscopy). In the case of stones in the bile duct (dislodged gallstones) an endoscopy (ERCP) is not possible to retrieve the stones, so if necessary, the bile duct may be operated on by using minimal invasive keyhole techniques.

Postoperative follow up after all bariatric operations:
Dr Puhalla and his team do regular medical check-ups after surgery to ensure the best possible outcome. The daily intake of a multi vitamin tablet to prevent vitamin or micronutrients deficiencies is strongly recommended.
