As with all operations, risks and chances of complications are involved with bariatric surgery. However, these are rare. Your bariatric surgeon and specialist team will do everything to prevent these complications. Therefore before, during and after surgery you are carefully monitored.


Your surgical risk is not equal to that of someone else. Moreover, not every operation involves the same risk. Your surgeon will discuss your specific situation with you.


If necessary, after surgery you will stay on a special monitoring department. Also,before the operation takes place you will be examined for disorders or illnesses that may increase surgical risk.


The biggest risk is a leak occurring in the intestine or stomach after the surgery. This allows a peritonitis due to body fluids in the abdominal cavity. If someone has undergone previous surgery in the same area, they have a higher risk of such leakage.


Another risk is the occurrence of a pulmonary embolism caused by deep vein thrombosis (DVT). Overweight people have a much greater chance that during surgery DVT occurs. This risk is minimized by the patient by moving as quickly as possible after the operation. Also, blood thinning medication will be administered.


Other risks are (after) bleeding, wound infections, pneumonia or urinary tract infections.

After the operation

A final risk is formed by the diet afterwards. Depending on the surgery, the diet should be adjusted. For example, eating different and less food. The NOK will address this issue extensively during the subsequent course.
