Preoperative Liquid Protein Diet

In preparation for your surgery, you might be asked to lose some weight in order to facilitate laparoscopic approach. This is usually started 2 weeks to 2 days prior to scheduled surgery. This approach is used to reduce thickness and stiffness of the abdominal wall, reduce enlarged liver, and assist the surgeon in flawless execution of the procedure. It also improves your mobility and work of effective breathing.

Liquid protein diet is designed to restrict non-protein calories while maintaining adequate nutritional status, which results in rapid, significant weight loss.

In the weeks before your procedure, your surgeon will place you on a pre-bariatric surgery liquid diet. How long this lasts and what the step-up process looks like varies between patients. Here’s what you need to know about this diet.

With most bariatric procedures, your surgeon needs to make alterations to the stomach, and possibly the intestines and other organs as well. To make these changes safely, the stomach and intestines must be free of food. Even when no surgical alterations are made, an empty stomach is still required for ideal outcomes.

However, the liquid diet before weight loss surgery usually starts well in advance of the point when it is needed to clear the digestive tract. This is because it is also used to reduce the size of the liver. For many people with obesity, their liver is fatty and enlarged, making it more dangerous to alter the stomach.

The specifics of your liquid diet before bariatric surgery can vary based on your unique needs. For example, if you are a diabetic, you might need to consume specific liquids to keep your blood sugar levels steady, while someone prone to muscle loss might need to really up their protein. In any case, follow the diet your doctor creates for you.

A typical liquid diet prior to bariatric surgery is as follows:

• Protein shakes
• Broth
• Skim milk
• Sugar-free drinks without carbonation
• Flavored or infused water (with infusions removed before consumption)
• Sugar-free Jell-O
• Sugar-free popsicles
• Decaf tea

Keep in mind that you usually move from a full liquid diet to a clear liquid diet 24-48 hours before surgery, so during that time, your list of approved items will become more restricted. As always, follow the instructions of your doctor to a T.
