Gastric Sleeve


This works on a relatively similar principle as the Gastric Bypass approach, namely it reduces the size of the stomach’s volume this reducing both physical capacity and the surface area through which digested food can be taken into the body.

Instead of moving the ‘plumbing’ to form a bypass, with a Sleeve, a part of the stomach itself is simply removed and the place from which it was separated is closed leaving a smaller and narrower stomach.

The effect on the patient is an earlier feeling of fullness during a meal, leading to a smaller food intake.

As with the Gastric Bypass technique, research has shown that this approach has interesting and dramatic effects on weight loss and diabetes, including helpful changes in certain hormones produced in the digestive system that affect appetite and the metabolism of sugars and fats.

The advantages of the Sleeve approach:

  • The operation is quick – typically taking about 45 − 60 minutes.
  • It is less complex to perform than the Gastric Bypass approach – with perhaps an even better impact on reducing Type II Diabetes and Hypertension (high blood pressure)
  • Once performed there are no later hospital visits for adjustment as there are with the Band technique
  • Equal in effectiveness to the Gastric Band approach
  • Can be converted to a bypass later, if deemed helpful.
