Gastric Sleeve Advice

Diet & Nutrition expectations

Once you decide to have gastric sleeve surgery you will be given advice about the diet you will need to follow and your nutrition requirements.

You will start your pre-op diet two weeks before surgery and continue afterwards with a post-op diet that takes your through five stages: clear liquids, full liquids, pureed foods, soft foods, and your ongoing normal low-calorie, protein-rich diet.

You must follow a gastric sleeve diet to achieve your desired weight loss after gastric sleeve surgery and eventually to maintain your weight.

Your stomach is reduced by approximately 75% after gastric sleeve surgery so you will be satisfied with much less food.

Weight loss following gastric sleeve surgery

The amount of weight loss you will lose following gastric sleeve surgery will depend on a number of things including: your diet, the amount you exercise, and your overall commitment to changing your lifestyle.

On average gastric sleeve patients lose around 60 percent of their excess body weight after surgery.

You will start losing weight from day one after your gastric sleeve operation. You can expect most of your weight loss to occur in the first six months.

Once you start to see your weight loss results you will be motivated to lose more, eat healthier and show off your amazing progress.

You need to maintain a limited calorie intake to keep losing excess weight.

Rapid substantial weight loss can also help you to become more active faster. An increase in physical activities helps burn calories and lose weight. Eventually you may reach a weight plateau and you will need to consider increasing the amount of time, type and pace of exercise you do.

Try to keep motivated and celebrate your successes of reaching your weight loss goals.

Once you reach your desired weight you must continue your gastric sleeve diet to maintain your weight and ensure it does not start to increase again.

Medical Issues following surgery

Gastric sleeve surgery is major surgery. As such it has potential risks and complications. However, you should keep in mind that most patients do not have complications after a gastric sleeve surgery.

It is important that you are informed before your gastric sleeve surgery about all the possible medical issues. Your weight loss surgeon will discuss these in detail with you before you decide to have gastric sleeve surgery.

Possible gastric sleeve complications include:

  • Staple line leakage of your digestive content that could lead to serious infection.
  • A wound site infection where your surgeon made the small incisions for their instruments.
  • A stricture where the opening to or from your stomach is inflamed and/or blocked preventing all or some of your food from entering your stomach or intestines.
  • Injury to organs adjacent to the surgical site including your stomach and intestines.
  • An inflamed stomach lining known as Gastritis, heartburn, or stomach ulcers.
  • Vomiting from overeating as your small stomach cannot hold the contents.
  • Dumping syndrome, also called rapid gastric emptying, is when food moves from your stomach to your small intestine before your stomach has adequately digested it. Trigger foods tend to be fatty, sugary, or generally rich foods that are not recommended in your gastric sleeve advice and are not supportive of your gastric sleeve diet. Symptoms include: stomach cramps, dizziness, nausea, vomiting and diarrhoea. This is less common in gastric sleeve patients than gastric bypass patients.
