Bariatric & metabolic surgery

Weight loss surgery options

Take control of your future with a range of weight loss surgery options.

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.

Bariatric and metabolic surgery options.

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.

Advantages
  • No intestinal surgery
  • Both a restrictive and metabolic procedure
  • No foreign body
  • Good quality of eating
Disadvantages
  • Irreversible operation
  • Risk of gastro-oesophageal reflux
  • Risk of staple line leak
  • Risk of micronutrient deficiency

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.

Advantages
  • Considered the gold standard of weight loss surgery
  • Considered reversible
  • Significant weight loss
  • Maintain good quality of eating
Disadvantages
  • Risk of small bowel obstruction
  • Risk of stomach ulcer
  • Risk of micronutrient deficiencies
  • Risk of dumping syndrome
