Pre-op diet before your VSG | Gastric Sleeve Surgery | Questions and Answers

For most people undergoing gastric sleeve surgery, the amount of time you will need to be on the pre-op diet depends on your BMI. Check BMI requirements to see how long your pre-op diet will take.

The purpose of this diet is to help shrink your liver prior to surgery by depleting stored glycogen.

  • 1 2 protein shakes per day -You may purchase these in any health food store or many grocery stores. Please be sure it contains at least 20 grams of protein per serving. Sugar should be 5 grams or less.

  • You can make your shake with unsweetened vanilla almond milk or unsweetened coconut milk

  • NO bread, rice, pasta, refined grains, tortillas, sauces with sugar, and no dairy

  • STOP nicotine products 2 months before surgery. Ask your primary care provider for Chantix and Wellbutrin. These two medications taken together are highly effective in stopping nicotine cravings.

  • OPTIONAL: Start taking a probiotic 6 weeks prior to surgery or as soon as possible. You want one that has a minimum of 50 billion units and the more strains the more effective and discontinue 2 weeks before surgery.

Hypoglycemia And Dumping Syndrome

Diagnosis of post BS hypoglycemia requires the compresence of neuro-glycopenic symptoms , blood glucose concentration less than 3.0 mmol/L , and symptoms relief by carbohydrates, according to the Whipples triad . Available provocation tests are the oral glucose tolerance test and the mixed meal tolerance test. Although the latest test should be considered the best provocative test to diagnose post-prandial reactive hypoglycemia, there is no currently an accepted standard meal test.

The terms hypoglycemia and late dumping syndrome have often been used interchangeably. Hypoglycemia after BS is exclusively post-prandial and many bariatric patients have postprandial autonomic symptoms, such as lightheadedness, palpitations and fatigue, which may represent manifestations of the dumping syndrome but also overlap significantly with the autonomic symptoms of hypoglycemia. To differentiate between symptoms related to post-RYGB hypoglycemia or late dumping, we can use the time of onset from surgery, with dumping usually developing shortly after RYGB and hypoglycemia generally manifesting later . In a cross-sectional study with and without documented post-RYGB hypoglycemia, it was demonstrated that a history of dumping syndrome did not increase the likelihood of hypoglycemia during meal studies , suggesting that dumping and hypoglycemia may share the common underlying mechanism , but they manifest different aspects of deregulated gut physiology.

Reason #: Decrease Liver Size

Reason number three is, in my opinion, the most important one. As you gained weight your liver grew with you. You get was its called a Fatty Liver.

The problem with having a large liver during bariatric surgery is that your surgeon might not be able to complete the operation.

Let me explain.

The stomach is located under the liver. During surgery, your bariatric surgeon will elevate the liver to get to the stomach so he can make it smaller so you can lose weight.

If your liver is excessively enlarged, the surgeon might not be able to get to the stomach. I saw two patients during my residency at the University of Florida in Gainesville prior to implementing the liquid diet that the surgery had to be aborted due to a large liver.

It is scientifically proven that just 2 weeks on a Low Fat, Low Carbs, High Protein, Low-Calorie diet will decrease your liver size by at least 25 percent.

So, dont take the chance. Stick to the diet and your surgery most likely will be completed as planned.

Gastric Sleeve Diet Restrictions

Going from eating a lot to eating very little is the main concept of a gastric sleeve diet. Before surgery, pre-op patients are put on a liquid diet fourteen days before their procedure. They are also told to skip certain vices and follow their restrictive diet to the core.

Once the patients have gone under the knife, they are put on a clear liquid diet for the first week. This means they can only consume water, green tea, light broths, sugar-free drinks and the like.

The liquid diet goes on for two more weeks. Come Week 4, patients are now slowly introducing solid yet soft foods into their diet. Steamed fish, scrambled eggs, unsweetened applesauce are some of the best examples of food consumed during this stage. Red meat and foods high in fat and sugar are prohibited.

After the first four weeks, patients are now free to eat solid foods again. However, whatever they consume must always be low in fat, low in carbohydrates, and high in proteins. Other nutrients such as fiber and omega 3 fatty acids can also aid in maintaining better health. Furthermore, vitamins and dietary minerals should be part of their daily meals as well as regular exercise. In fact, exercise plays a major role in keeping the weight off.

Diet Before Your Surgery

Losing weight before surgery helps reduce the amount of fat in and around your liver and abdomen. This may allow you to have a laparoscopy rather than open surgery. Laparoscopic surgery is less invasive, requires much less recovery time, and is easier on your body.

Losing weight prior to surgery not only keeps you safer during the procedure, but it also helps train you for a new way of eating.

Your exact eating plan and pre-op weight loss goal will be determined by your healthcare provider and likely with the help of a registered dietitian.

Your eating plan may begin as soon as youre cleared for the procedure. If sufficient weight loss doesnt occur, the procedure may be postponed or canceled. For this reason, you should start the diet plan as soon as you can.

There are some liquids that should be avoided such as high sugar liquids, fruit juices, some sports drinks, alcoholic beverages, whole or 2% milk, soda, coffee, and caffeinated tea.

Why Is A Liquid Diet Before Bariatric Surgery Important

One of the most important reasons for strictly following a liquid diet is simply because it is easier and safer to perform bariatric surgery on patients with fewer barriers to the stomach. Many obese patients have a fatty liver, meaning the liver has expanded in size as they gained excessive weight.

Because the liver sits atop the stomach, surgeons may not be able to access the stomach and cancel surgery in these situations. A liquid diet in the weeks before bariatric surgery is known to decrease the size of fatty livers, helping it to be a successful surgery.

Furthermore, the liquid diet that your surgeon or dietitian assigns to you will include many protein shakes. During periods of rapid weight loss, healthy muscle mass breaks down as well. Following your liquid diet will ensure that you are consuming at least 60 grams of protein a day.

Nutritional Assessment Before Bs

RNY Gastric Bypass Nutrition

Assessment of nutritional status of candidates to BS before the operation plays an important role in the post-surgical management. During the last few years, several studies demonstrated that patients with severe obesity often display micronutrient deficiencies when compared to normal weight controls. In 2008, Asheim et al. analyzed the vitamin status of 110 patients affected by severe obesity as compared with 58 normal weight subjects: patients with obesity had significantly lower concentrations of vitamins A, B6, C, 25-hydroxyvitamin D, and lipid-standardized vitamin E . Similarly, Van Rutte et al. demonstrated in 200 patients affected by severe obesity that 38% of them had low serum iron, 24% had low serum folate, 11% had low serum vit. B12 and 81% had hypovitaminosis D . Finally, Peterson et al. demonstrated a frank deficiency of vitamin D and iron in 71.4% and 36.2% of 58 BS candidates .

MDs in patients with severe obesity could be attributed to a poor-quality, non-varied, high-calorie and high-fat diet. For example, excessive simple sugar, milk products or fats could lead to a deficit of vitamin B1 . Moreover, iron status could be affected by adipose tissue inflammation and increased expression of the systemic iron regulatory protein hepcidin . Lastly, the increased adipose mass could act as a storage site for highly lipophilic molecules, such as vitamin D, and this could explain the difference in 25D levels between people with or without obesity .

  • Take your time and eat slowly.
  • Walking can help food move out of stomach pouch.
  • Overall goal is to get 100 grams of protein and 100 grams carbohydrate each day, but you are doing well to get over 50-60gms of protein and carbs at this stage. Drinking 3 cups double milk each day provides 48 grams protein and 72 grams carbohydrate. These can be consumed hot, cold or flavored in a variety of ways.
  • If you feel gassy, bloated or have loose stools on this diet, it may be lactose intolerance. This is generally temporary. Take Lactase enzyme tablets or eat yogurt or try soy milk or lactose-free milk to alleviate symptoms.
  • Constipation is not uncommon on this diet. Add Benefiber, FiberSure or Metamucil-Smooth to each double milk to promote regularity.

Keep walking to promote regularity, as well. Walk at least 30 minutes/day. If you lift weights, you need to lift less than 10 lbs and avoid any abdominal exercises.
