NUTRITIONAL CHANGES AFTER BARIATRIC SURGERY

For most patients, the benefits of bariatric surgery far outweigh the risks. Patients need to know that, maintaining  weight loss requires some work on their part particularly with regard to diet and exercises.

Patients need to be on a liquid diet for 2 weeks after surgery. Then they switch to semi solid
diet and gradually progress to soft and then normal diet. The duration of this transition depends upon the type of surgery.

LIQUIDS:

  •  Patients are encouraged to drink at least 2 L of fluids daily to avoid dehydration, constipation and kidney stones.
  •  You can tell if you are getting enough fluid, if you are passing clear light coloured urine 5 to 10 times a day.

PROTEINS:

  • Patients are advised to take between 60 to 80 g of proteins daily.
  • During raid weight loss after surgery, the body needs additional proteins to maintain the muscle proteins.
  • The daily requirement of proteins needs to be taken in multiple doses as the body cannot absorb more than 30 g in one go.

CARBOHYDRATES:

  • ·Patients are asked to cut down on excessive carbohydrate intake (rice, rotis, breads, pastas, cakes, candy). Limiting the carbohydrate intake to 50 g or less helps avoid rebound hunger problems.

VITAMINS & MINERALS:

  • ·Multivitamins, calcium and vitamin D are supplemented in most patients after a bariatric surgery. In case of mal-absorptive surgery (Gastric Bypass), iron, vitamin B12 and sometimes vitamin A also need to be supplemented.
