Bariatric (Weight Loss) Surgery
Bariatric (weight loss) surgery is increasing in Australia as clinical research supporting its effectiveness in weight control and co-morbidity (associated health risks) improvement continues to accumulate.
According to WHO (World Health Organization) data 65% of the world's population live in a country where overweight and obesity kills more people than underweight. This includes all high-income and middle-income countries. Globally, 44% of diabetes, 23% of ischaemic heart disease and 7–41% of certain cancers are attributable to overweight and obesity.
With levels of obesity and associated medical conditions (particularly type 2 Diabetes) in our community at an all-time high, it is important that doctors and patients be familiar with the range of treatment options available, including bariatric surgery.
Types of Bariatric Surgery
Gastric Banding & Lapband Surgery - the gastric band is particularly effective in people who have excessive hunger and/or need big portions to feel satisfied. Patients who can lose weight quite easily with diets and exercise but struggle to keep it off tend to do very well with the gastric band, which helps end the yo-yo cycles and is more powerful than diets and exercise alone. One of the main reasons gastric band surgery is more popular than other forms of weight-loss surgery is because it can be reversed.
Gastric Sleeve - involves the permanent removal of 85-90% of the stomach, performed under a General Anaesthetic using advanced laparoscopic keyhole surgery. Although the physical size of the stomach is reduced, the normal direction of the food stream through the stomach and the rest of the intestinal tract is not altered. This means that all nutrients including vitamins, minerals and protein will continue to be absorbed normally. It simply reduces the holding capacity from about 1.5 litres of food and liquid to approximately 200mls. This allows a person to feel comfortably satisfied and full with a meal size approximately equivalent to a cup of food.
Gastric Bypass - Gastric Bypass is one of the most common surgical procedures used in the treatment of Obesity around the world. Gastric Bypass surgery is a restrictive/malabsorptive surgical procedure. It is restrictive in the sense that it “restricts” how much food the stomach can hold and is “malabsorptive” in that it affects how food and calories are absorbed into the bloodstream. This combination surgery has the highest success rate for amount of weight lost, making it an incredibly popular weight loss surgery option.
