Meal Guide for Bariatric Surgery

This meal guide will assist you in making the best dietary choices during your stay in hospital.

After your surgery, you will be admitted to the hospital ward and allowed to have nourishing fluids once cleared by your surgeon. You are recommended to:

  • Prioritise nourishing fluids, drink these first
  • Sip on other low energy fluids regularly throughout the day to maintain hydration. This includes water, tea or coffee (no sugar) or diet cordial.
  • Aim to drink a total of 1.5 litres of fluid per day.

Nourishing fluids will need to be low in fat and sugar, have no lumps and thin enough to drink through a straw. You will receive the following nourishing fluids in hospital:

  • High protein milkshakes or smoothies
  • Liquid pureed soup or consomm√©
  • Ice cream or sorbet (limit intake)
  • Custard
  • Puree fruit
  • Low fat milk
  • Sustagen
  • Fortsip
  • High protein milo
  • Juices (limit intake)

**Please advise your nurse if you have any food allergies or intolerances.

Special note:
Be aware that you will be unable to consume all the fluids served in one sitting.  Sip on these fluids throughout the day and ensure you avoid straws and carbonated drinks as they can cause you to swallow excess air.  If you feel uncomfortable, nauseous or vomit it is likely you have consumed too much.     

*Ensure that you do not use a straw for drinking as it can cause you to swallow excess air.
