Bariatric surgery is an effective tool for helping to treat obesity and combat weight gain.
With statistics showing that every 2 in 3 Australian adults are overweight, it’s undeniable that obesity is a growing issue. However, contrary to popular belief, obesity is complex. Things like genetics, insulin and certain medications can affect how your body retains weight. Dr Dolan understands that losing weight can be both physically and emotionally challenging but with over twenty years of experience he has helped thousands of patients to lose weight.
If you are morbidly obese, overweight by more than 20 kilograms, or have battled obesity for many years, weight loss surgery may be the solution you have been looking for. These procedures can facilitate weight loss and improve the overall quality of your life.
Dr Dolan’s Weight Loss Procedures
Gastric Sleeve – involves removing three-quarters of the bottom part of the stomach.
This restricts the amount of food a patient can consume and more importantly reduces the amount of hunger hormone ghrelin that the stomach produces. This helps patients lose weight by decreasing the amount they can eat and also decreasing their hunger between meals.
Mini Gastric Bypass – a simplified form of a standard gastric bypass surgery.
The surgery uses a combination of restrictive and malabsorptive techniques to reduce the size of the stomach and alter hormones involved in appetite control. It is also an operation which is gaining recognition for the eradication of diabetes in insulin and non-insulin dependent patients.
Stomach Intestinal Pylorus Preserving Surgery (SIPS) – a modified version of the duodenal switch, which has been used for the treatment of morbid obesity for 30 years. SIPS combines the benefits of sleeve gastrectomy and intestinal bypass.
Sleeve gastrectomy removes 75% of the stomach resulting in a reduced capacity to eat and a reduced level of ghrelin, the hormone which causes hunger. Intestinal bypass involves dividing the top part of the small bowel (duodenum) just beyond the outlet of the stomach (pylorus), and joining the lower part of the small bowel (ileum) to this top part.
This results in food bypassing part of the small intestine which causes a reduction in the absorption of fats, sugar and calories that are consumed. The amount of the small bowel bypassed can be varied depending on the desired weight loss.
Laparoscopic Adjustable Gastric Band Surgery – a reversible procedure where an adjustable silicon band is placed around the upper section of the patient’s stomach. Adjusting the size of the band restricts the amount of food that can be consumed by the patient, facilitating weight loss.
Lap-band surgery is suitable for patients who want to permanently lose a significant amount of weight. After surgery patients should expect to lose between 0.5-1 kilogram a week for the first 12-18 months
Roux-en-Y Gastric Bypass – often the most effective treatment for patients suffering from morbid obesity and those who have severe acid reflux. The size of the patient’s stomach is decreased so that only small portions of food can be consumed and part of the intestines are bypassed meaning that fewer calories are absorbed.
If you are morbidly obese with severe reflux RYGB may be a suitable treatment. Within the first two years, patients can expect to lose between 70-80 percent of their excess body weight.
