BandBoozled on liquids following surgery

Share Story

Following weight loss surgery, whether that is a gastric band, sleeve or bypass, you will usually be required to follow a liquid only diet for around 2 weeks.

This is important in order to allow the stomach area to heal properly as this way, particularly if it is swollen as liquids are able to pass through much more easily without causing any problems.

Gastric band experts Sue and Nic from the UK slimming club BandBoozled gave us their top tips for the initial liquid diet following surgery:

  • Liquids should be thin in consistency with no lumps and bumps – basically they should fit through a straw however we don’t recommend that you use a straw.
  • Sip your liquids slowly and have at least a 20-second rest between each mouthful.
  • You may find that you can’t manage much and you are having to sip almost continuously throughout the day. A recommended portion size is around 200mls and the focus should be on protein-containing liquids like milk, meal replacements, pulse-based soups and drinking yoghurt to aid your healing.
  • Aim to have around 5 or 6 portions daily depending on your chosen weight loss surgery and then drink extra water (or tea and coffee) to increase your total fluid intake.
  • A good tip is to measure the colour of your urine – it should be pale and straw coloured however if it is darker and more concentrated then this is an indication that you need to drink more fluids.

Your specialist dietitians will be there to support you every step of the way and will give you the advice and guidance you need during your post-operative consultations.
