Post-Operation Bariatric Surgery Diet

Post-Operation Bariatric Surgery Diet

Once the gastric surgery has been completed, it is very important that you follow a strict diet, as this ensures your stomach can heal correctly. Eating solid foods too soon can put too much stress on the stomach wound, causing leakages.

The post-surgery diet is comprised of three stages:

  • Weeks 1 to 4
  • Weeks 4 to 6
  • Weeks 6+

Weeks 1 to 4

During this time, no solid food should be consumed, as it can damage the stomach. Food must be puréed, and you can do this with a blender or food processor.

Eat four or five 100g portions of puréed food per day. Take small mouthfuls and eat food slowly, ensuring to stop as soon as you feel full.

Foods that can be puréed include lean meats, fish, eggs, soft fruit and cottage cheese. These foods should be blended with liquid. Drink small mouthfuls of water often, aiming for 1.5 litres per day, but never drink during your meal, wait at least 30 minutes.

Weeks 4 to 6

Although food at this stage does not need to be puréed, it should still be soft. Foods such as porridge, mashed potatoes, soup, melted cheese, yoghurt and rice pudding can all be consumed in moderation. However, if these cause any distress then it is advisable to go back to the puréed diet for another week.

Weeks 6+

After six weeks you should start to introduce foods that you have not consumed since the surgery, and see how your body reacts to them. Do this slowly, introducing foods one by one. It is important that once you can eat normally, you don’t go back to unhealthy eating patterns.
