Post-operative diet

Bariatric surgery patients will need to follow a special, customized diet following surgery. A dietician who is part of your care team will provide dietary guidelines. It’s essential that these guidelines are followed, as non-compliance can lead to serious malnutrition and general poor health. Below are basic rules for eating, drinking and exercise that will help patients get the best results:

  • Eat only three meals per day
  • Eat slowly and chew thoroughly
  • Stop eating as soon as you feel full
  • Do not drink while you are eating
  • Do not eat between meals
  • Eat only good quality foods
  • Avoid fibrous foods
  • Drink enough fluids during the day in between meals
  • Drink only low-calorie liquids
  • Exercise at least 30 minutes per day
  • Take your multi-vitamins daily

Any weight loss surgery may cause malnutrition and or malabsorption, which may lead to some vitamin/mineral deficiencies. The most common are ones B12, iron and protein deficiencies. Supplementation is necessary.

Patients should plan to see their surgeon for important follow-up visits. At each visit your general health, diet, exercise regimen, medications and/or vitamin/mineral supplements will be reviewed. Patients should use this opportunity to discuss any problems or concerns they may be having related to the surgery. Blood work will also be done periodically. Patients may wish to see the dietician periodically to re-evaluate their diet. Weight loss will also be monitored to help ensure patients are moving toward their desired goals.
