What to Expect Before Bariatric Surgery
The following are explanations of important preparations to take before bariatric surgery.
On the morning of your bariatric procedure, do not eat or drink anything – not even juice, coffee, water, or gum!
Continue to take all your usual medications in their usual doses. If you normally take any medications for blood pressure or heart problems in the morning, these can be taken with a SMALL sip of water on the morning of surgery.
Please follow these directions with regard to medications, prescription and over-the-counter medications:
- Continue all your usual medications in their usual doses. Nothing to eat or drink after midnight the night before your bariatric surgery (unless if taking medication for blood pressure and/or diabetes. Anything more specific, please ask).
- Please ask your doctor whether to continue any pill medications for your diabetes. If you use insulin, we will frequently suggest that you only take half of your normal morning dose, but please verify this with Dr. Bhoyrul if instructions have not been given to you.
- If you take Coumadin (a type of blood thinner), we will frequently suggest that you discontinue this medication 5 days prior to your operation. Only discontinue this following the specific instructions of your doctor.
Due to the risk of increased bleeding, you should stop any of the following medications at least 10 days prior to surgery:
Any other medications not listed, please discuss with your surgeon. It is okay to take Tylenol.
The same day of surgery: You must have a responsible adult available to drive you home following your procedure. Due to anesthesia considerations, you also need to have a responsible adult available at home that evening.
Physical Limitations: Do not lift more than 10 pounds for 4 weeks following your surgery.
Liver Shrinking Diet for weight loss surgery patients
The purpose of the Liver Shrinking Diet before weight loss surgery is to reduce the size of your liver and make it easier for the surgeon to operate as the stomach is located underneath the liver. You will need to start this liquid diet 5-10 days before surgery. Remember to get at least 60gm of protein and minimize your intake of high sugar and high fat liquids. Choices include:
A. PROTEIN SHAKES:

You may drink 1-2 shakes a day and can use them as a meal replacement only during this diet phase. You will find them at Costco, Walgreens, CVS and GNC. DO NOT BUY: Regular Slim Fast, Ensure, Boost, Atkins.
