The role of any weight loss surgery is to control one’s hunger. The sleeve gastrectomy achieves this by reducing the stomach capacity from 2L down to 100-150ml, so providing a physical barrier to help portion control the meals. In addition, recent studies have shown that the hunger hormone Grehlin is removed when the top fundus of the stomach is removed during the procedure.
Similar to the Lap Band, the transitional dietary phases the liver needs to be reduced by following through with Optifast for 2-4 weeks prior to surgery, as recommended by your specific weight loss surgery clinic. There are also Optifast recipes which are carbohydrate free and suitable during the optifast phase.
This is followed by 2 weeks of fluids post the sleeve gastrectomy surgery to ensure the scar line is healed, minimizing any leaks from occurring. Helen Bauzon recommends you keep to Optifast of three VLCD meal replacements per day as a minimum as it is hard to consume adequate nutrition otherwise.
Once 125ml of liquid can be tolerated comfortably in a 5-10min sitting, at the beginning of week three you can begin to transition onto solid food otherwise you need to wait additional time until the swelling has settled more before beginning to eat solid food.
Similar to the Lap Band, the degree of chewing is crucial to maintaining a good variety of food with the sleeve gsatrectomy. Another key point to remember, do not stretch your sleeve beyond 3/4 to 1 cup volume in one sitting.
The sleeve gastrectomy is not a set and forget surgery.things can go wrong. Malnutrition must be avoided as the effect of some deficiencies can not be reversed. An appointment with Dietitian Helen Bauzon is highly recommended to help make your diet nutritionally adequate especially early after surgery.
