Day of Surgery

They day of your surgery is a important and we will be with you every step.  

Preparations for the Day of Surgery

It’s critical that you follow your surgeon’s specific instructions the day of surgery.

These instructions generally include:

  • Pre-surgery fasting, we require a fast to begin 5-days prior to surgery.
  • Drink 6 packets of no added sugar Carnation Instant Breakfast daily (or other low calorie, high protein drink).
  • Drink an additional 32 ounces (4 cups) of non-caloric fluids daily.
  • Do not drink or eat anything prior to surgery—most often this clear liquid fasting period begins the night before surgery.
  • Most medicines can be taken the day of surgery, just with small sips of water. Your doctor will have instructions regarding specific medications.
  • Bring all of your medications with you.
  • If you have a CPAP (Continuous Positive Airway Pressure) machine, bring it with you for use in the hospital.
  • Arrive early. Some hospitals and surgery centers require patients to arrive two hours early.

The purpose of the fast is:

  • To decrease the fat on your liver.
  • To decrease surgical risks.
  • To demonstrate your tolerance to a liquid diet.
  • To mentally prepare yourself for diet changes that will take place after your surgery.

What to Expect the Day of Surgery

  • When you arrive, you will undergo several preoperative steps.
  • You will speak with nurses, your surgeon, and your anesthesiologist.
  • An IV will be started to keep you hydrated and to administer medications.
  • The preoperative experience is often a short one, after which you will be taken to the operating room.
  • Your anesthesiologist will give you anesthesia medications to sedate you before actually putting you to sleep.
  • Bariatric procedures, whether they are minimally invasive or open, generally take 75 to 90 minutes.
  • After surgery, your healthcare team will continue monitoring you in the recovery room, and then will arrange for you to move to the appropriate nursing unit or outpatient discharge area.

If you have questions or concerns about your surgery, please discuss them with your bariatric team.
