Bariatric surgery results in caloric restriction and may also cause long term malabsorption of nutrients. This causes a gradual and sustained weight loss which may continue for a year or more.
Many patients are concerned that surgery may result in weakness of their body over the long term. This may happen if there is deficiency of protein or essential vitamins and minerals in the body. To prevent this complication from occurring, the patients are educated regarding their diet and supplements right from the beginning. There are instructed to consume a high protein diet with plenty of vitamins and minerals. Besides, calcium, iron and B complex vitamins are supplemented right from day 1 of bariatric surgery. Protein is also supplemented in the form of protein powder. Sometimes, vitamins may be required as injections.
If the diet plan is adhered to strictly along with regular supplements then there are very less chances of deficiency and body weakness after bariatric surgery.
