Will there be a drain in my abdomen after my gastric bypass surgery?
Your surgeon should use a thin silicone drain to prevent fluid accumulation in the abdomen and as a precaution. This is a safety measure, does not mean there is a problem related to your operation. Usually, your nurse will remove your drain on the 2nd or 3rd day of the surgery. In general, the drain does not cause any serious problems.
Is the gall bladder also removed in my gastric bypass surgery?
It is not a common surgery process to remove gallbladder. Unless you have an ultrasound proven gallbladder stone, you can request the same. Your surgeon should inform you about some medications to prevent the development of gallstones during the rapid weight loss period of 6 months after surgery. This can change to patient to patient and thus will be decided accordingly.
