There are several weight loss surgery options available depending on your needs, general overall health, and weight loss objectives. All operations are not appropriate for all patients.
Dr Benedict Mackay offers a comprehensive range of bariatric surgical treatments. Sleeve Gastrectomy (LSG) and Roux-en-Y Gastric Bypass are two of the more commonly performed bariatric procedures in Australia.
In this procedure, approximately 80% of the stomach is removed. The surgery works by restriction (smaller stomach) and complex metabolic (gastrointestinal hormonal changes). The end result is less hunger and earlier satiety/fullness with food.
The average weight loss is about 65 to 70% of excess weight over twelve to eighteen months.
Sleeve Gastrectomies are performed laparoscopically and require a two- to three-day hospital stay. Patients generally return to work within two to four weeks.
RYGB works with a more profound metabolic and restrictive component than the Sleeve Gastrectomy. Most of the stomach and part of the small intestine is completely bypassed in this procedure. Similar to the sleeve, hunger hormones are reduced and satiety hormones increased. Patients are less hungry and satiated (full) with small amounts of food.
Weight loss is significant for most patients and plateaus over twelve to eighteen months. The average weight loss is 75% of excess weight and weight loss is generally considered more durable than in Sleeve Gastrectomies.
