Bariatric Surgery : Pre and Post-Operative Care & Diet

The success rate and Effective Weight Loss (EWL) of bariatric surgery depends a lot on the preparation you do do BOTH before and after the surgery.  It will also help to reduce the side effects of the surgery and help you recover faster.

Pre Operative Care Guidelines

Prior to the surgery, you should be motivated to change your lifestyle and diet to get the maximum benefit and results from your surgery.  Discuss with your nutritionist or dietician how to prepare for the surgery.

Post Operative Care Guidelines

1. Diet.  Immediately after surgery, your gut will need time to adjust to solid foods.  If not, your food will pass too quickly from your stomach (which has been shortened after the surgery) to your small intestine causing nausea, dizziness, diarrhoea or vomiting.  This is known as the ‘dumping syndrome’.

In the first week starting with clear fluids before progressing to thicker liquid such as soups or protein drinks

  • Water
  • Tea or decaffeinated coffee without sugar
  • Soup
  • Diluted fruit juice
  • Special protein liquid drink

In the second week, you may progress to liquid or pureed foods such as

  • Pureed vegetables or beans
  • Pureed meats
  • Yoghurt
  • Tofu in any form
  • Eggs
  • Fish (preferably steamed)

In the first month, you can progress to a soft diet which consists of foods which are easy to chew, swallow and digest.  This includes

  • Steamed or cooked vegetables with no skin or seeds
  • Mashed potatoes
  • Steamed fish
  • Shredded meat
  • Eggs
  • White rice
  • White bread
  • Pasta
  • Soups
  • Tofu

Finally, you need a change to a new diet to get the maximum benefit and success from the surgery.  Discuss with your doctor, dietician or nutritionist to create a dietary plan which you can enjoy to eat and follow without giving up.  Adopt the following good eating habits

  • Eat frequent but small meals (such as 5 small meals instead of 3 big ones)
  • Take your time to chew your foods before swallowing
  • Stop eating when you feel full.  Avoid over eating.
  • Drink and keep hydrated between meals
  • Avoid snacking on junk foods between meals

Avoid hard foods like nuts, spicy or fried foods, carbonated or sugary drinks and high calorie foods such as biscuits. sweets or chocolates

2. Supplements. After surgery, you need to take vitamin and mineral supplements such as multivitamins, Vitamin B12, Vitamin D, Iron and Calcium. 

3. Exercise.  You must try not to spend too much time being immobile and do some exercises with the help of a family member, fitness trainer or physiotherapist if need be.  This will increase your weight loss and well reduce the risk of the following possible conditions;

  • Deep vein thrombosis
  • Pulmonary embolism
  • Skin bed sores
