In order to loose weight and keep it off it is necessary not just to have the operation but also to eat a balanced diet and to exercise regularly.  Studies suggest that you will loose between 30% and 74% of your excess weight, the most rapid period of weight loss being in the first 18 to 24 months following surgery.  But, it does depend upon the weight loss treatment you have and how committed you are to your new lifestyle.  

 

 

All surgical procedures are associated with some risk and with an increased risk of complications generally associated with surgery on overweight patients.  In deciding whether to undergo weight loss surgery it is necessary to balance the risks of the procedure against the risks of obesity.  Complications that can occur following surgery include wound and chest infections, bleeding, injuries to the stomach and bowel, and leaks from thjoin in the bowel.

 

You will need to eat a normal balanced diet after surgery.  The operation will help in weight reduction but it is important to develop healthy eating habits and eating small portions.  Patients undergoing bypass surgery will need to take vitamins, iron and calcium supplements for life and increase their protein intake.

 

You should not become pregnant during the period of rapid weight loss but there is no reason not to after your weight loss has stabilised, which is usually about 18 to 24 months after the operation.

 

You may or may not.  Skin is elastic and will try to mould to your new body contour.  Sometimes though it may be beneficial to have excess skin removed via cosmetic surgery, eg a tummy tuck.
