Gastric bypass surgery—also called Roux-en-Y gastric bypass surgery (RYGB)—is a type of bariatric surgery that involves creating a small pouch out of a patient's existing stomach. This scheduled surgery requires careful preparation, as the end result demands a lifelong commitment to healthy diet and exercise habits.

Months before the surgery, patients must attend a presurgical education/lifestyle program. Then, two weeks before the operation, patients must stick to a liquid-only diet.

What to Wear

Your surgeon will likely advise you to shower either the night before or the morning of the surgery using a special type of antibacterial soap. You may be asked to focus on washing your abdominal area (where the surgery will take place).

 

 

It's important to leave jewelry, credit cards, and other valuables at home. In addition, do not wear any of the following on the day of your surgery:

 

 

  • Makeup
  • Fingernail polish
  • Perfume
  • Deodorant
  • Moisturizers

 

 

Food and Drink

 

 

About one to four weeks prior to surgery, your surgeon will ask you to begin a low-calorie liquid diet. This diet generally consists of two or more protein shakes daily, along with eight glasses of zero-calorie liquids, such as:

  • Water
  • Crystal Light
  • Unsweetened tea

 


In small amounts, patients can also usually have the following:

 

  • Sugar-free jello or popsicles
  • Black coffee with no sugar
  • Broths

 

 

The purpose of this strictly liquid diet is to decrease the size and stiffness of your liver. This will help your surgeon avoid injury to your abdominal organs during the actual surgery.

One or two days before surgery, you will probably be asked to only consume clear liquids. Then, on the eve of your surgery, you will be told not to eat or drink anything after 10 pm or midnight.

 

 

 

Medications

Your surgeon and anesthesiologist will instruct you to stop various medications prior to undergoing surgery. For example, about seven to 10 days prior to surgery, you will be advised to stop any nonsteroidal anti-inflammatory drugs (NSAIDs) like Motrin (ibuprofen), or Aleve (naproxen).

Starting the day or night before your operation, you may be asked to begin a bowel cleansing preparation. Instructions may vary, so be sure to follow your surgeon's directions. Reach out to them if you have any questions.

What to Bring

For gastric bypass surgery, you can expect to stay in the hospital for approximately two to five days.5 To prepare for your stay, pack these items and bring them with you on the day of your surgery:

  • Your driver's license and insurance card
  • Comfortable clothes to leave the hospital in
  • Personal items for your hospital stay, such as underwear, toothbrush, comb, glasses or contact lenses (with container), and a cell phone charger.
  • One or more "comfort" items, such as a sleep mask or a small pillow
  • Sleep apnea mask (if you have one)
  • Entertainment materials such as an e-book reader, tablet, books, music, headphones, etc.

 

 

Pre-Op Lifestyle Changes

Prior to undergoing gastric bypass surgery, your surgeon will ask you to do the following:

 

 

  • Engaging in an education/lifestyle program: Most insurance companies require that patients undergo a six-month pre-operative program to learn all about the surgery, including the short and long-term recovery process.
  • Losing weight: Your surgeon may advise you to lose weight on your own before surgery by starting an exercise routine and restricting your calorie intake.
  • Stopping smoking: Your surgeon will ask you to stop smoking for at least three months prior to your surgery. Stopping smoking lowers your chances of developing serious surgical complications, such as impaired wound healing.
  • Avoiding caffeine: Some surgeons ask their patients to avoid caffeine for at least one month before surgery.
