Bariatric (weight loss) Surgery

Obesity commonly affects 3 out of 5 Australians and is due to a number of factors. Factors that we are not able to change include genetics, the environment, farming and industry and our lived experiences. Obesity is complex and each patient is unique and this is why calorie restriction and dieting are largely unsuccessful. Weight loss surgery can cause weight loss over a shorter period of time, by reducing the stomach's capacity or reducing the intestines ability to absorb food, or both. On balance, surgery is a good solution if its risks and consequences are considered. Some patients with obesity suffer other medical conditions that are directly related to their weight or body mass index (BMI). In these patients, the risks of these medical conditions negatively impacting their life are greater than the risk and consequences of surgery. Here are some benefits of weight loss surgery for patients with obesity:

Heart and Lungs

  • Manage the risks of heart disease and coronary artery disease

  • Reduce severity or cease use of CPAP in OSA patients

  • Metabolic syndrome including risk factors for cardiac disease

  • Reduce or cease the puffers or medications needed to treat diabetes

  • Better control of Hba1c or the blood index for diabetes

  • Reduce or cease the puffers or medications needed to treat asthma

Bones and Joints

  • Reduce joint stress and arthritis

  • Increase mobility, activity and weight loss

  • Reach target weight for orthopaedic or spinal surgery

  • Increase access to care in different hospitals that have a cap on BMI

  • Increase the life of prosthesis or new joints in the hips and knees

Hormones and Reproduction

  • Reduce insulin resistance in PCOS patients

  • Improve fertility and menstrual cycle

  • Improve egg retrieval in IVF

  • Reduce the risk of pre-ecclampsia and gestational diabetes.

  • Reducing the risks of delivering the baby 

  • Improve infant and mother outcomes 

Risk Reduction

  • Improve access to other surgery

  • Improve outcomes of other surgery such as hernia and transplant surgery

  • Reduce the risk of cancer such as lung, thyroid, ovarian, uterine and colorectal cancer

  • Psychological disorders such as anxiety and depression are associated with obesity

Procedures

Sleeve Gastrectomy

Mini gastric bypass

Roux-en-Y gastric bypass (RYGB)

Laparoscopic Gastric Band (Revision only)

Laparoscopic Sleeve Gastrectomy

  • Primary restrictive procedure that reduces the volume of the stomach

  • Staged weight-loss operation with planned conversion to Roux-en-Y bypass for patients with very high BMIs

Mini Gastric Bypass

  • Primary restrictive (reduces the volume of the stomach) and malabsorptive (reduces absoprtion in the intestines) procedure

Laparoscopic Roux-en-Y gastric bypass (RYGB)

  • Primary restrictive (reduces the volume of the stomach) and malabsorptive (reduces absoprtion in the intestines) procedure

  • Staged revision surgery after failed primary restrictive procedure or due to reflux from primary restrictive procedure

Laparoscopic Gastric Banding (revision only)

  • Replacement of band or port

  • Removal of band or port

  • Reversal of banding with or without staged revision bypass surgery for weight loss
