What is the Purpose of Pre-Surgery Diet?

Your liver also has to be healthy to perform this procedure. Generally, to access your stomach for most bariatric surgeries, your surgeon will use a liver retractor. With this device, the surgeon lifts up the liver and performs the operation on stomach easily. But if you have fatty liver disease, this process becomes complicated. This increases the size of your liver. In this case, the surgeon either goes for a non-laparoscopic procedure or asks the patient to follow their 2 week pre-op diet.

What is the Gastric Sleeve Pre-Op Diet?

Before 2 weeks from surgery, you should start on a high protein diet. You can buy a protein shake from your local grocery store. This should be low in sugars and carbohydrates. Drink the protein shake for breakfast. Have lean meat and vegetable for lunch and dinner. This will help the liver shrink in size. You can also be on liquid diet (sugar-free) in-between the meals.
