Patients will typically be required to undergo two diet regimens, one before surgery (pre-op) and one after (post-op). They follow a brief guide to what you can expect from the dieting process before and after surgery. We specifically left out surgery types, but all patients will under similar dieting regimens. Here is what you can expect:
The main purpose of dieting before weight loss surgery is to decrease surgical risks that comes as a result of too much fat surrounding the abdominal and the liver.
Pre-Op Dieting and Nutrition
Some patients will be required to undergo a strict dieting plan for several weeks before the surgery date; some patients will need to be on a diet for several months before surgery. The main purpose of the pre-op diet is not to lose weight, but to decrease the fat that lives around the stomach and liver.
The diet is a low calorie, high protein diet that will need to be strictly maintained. Patients will normally consume 800 to 1200 calories per day for two weeks or in some cases much longer. The diet will normally be high in protein and low in sugar and fat.
The diet prescribed by surgeons will often be predominately liquid. The liquid diet will be easy for patients to consume the required protein intake. Patients should also avoid sugary drinks including soda, juices, and alcohol. Patients should try to consume lean meats and high-fiber foods: chicken breast, eggs, oatmeal, etc.
Post-Op Dieting and Nutrition
Post-surgery, patients, will again be put on a strict dieting plan. This time, it’s especially important for patients to follow the physician’s orders. Following the first few weeks from surgery, patients will need to follow the guidelines adamantly. Failure could cause delay healing, serious complications, or malnutrition.
Complications that Can Arise By Not Following Diet Plan Includes: Vomiting, Lap-Band displacement, disruption internally, pain, stomach stretching, bleeding at the sutures, stomach expansion and stomach blockage.
First Few Weeks: Patients will likely put on a strict liquid-based diet. This diet is specifically designed to help patient’s stomach heal. Overall, patients will be required to consume protein-rich liquids and at least 64-ounces of water throughout the day.
Clear Liquid Diet includes liquids like water, tea, diluted juices, protein fruit drinks, non-sugary or non-carbonated drinks.
Two Weeks After Surgery: Past the first few weeks patients will be allowed to consume more and more free types, as well as to consume pureed food. Other liquids include low-fat milk, soups, yogurt, and sugar-free jello.
Progressing past a few months patients will be able to incorporate soft foods, more pureed foods and eventually solid foods.
Each patient will be on a different schedule based on patient’s tolerance and their recovery. It will also be based on which surgery type ( gastric bypass, gastric sleeve, gastric banding, gastric plication) the patient has undergone. Patients with a gastric sleeve will in most cases be able to consume a longer list of foods than a gastric banding patient.
