Waratah Private Hospital is proud to offer people a complete holistic approach in weight loss through bariatric surgery with the most expert surgeons in this field and a team of dietitians, psychologists and rehabilitation services.

With over 67% of the Australian population aged 18 and over identified as overweight or obese, our team are dedicated to supporting people on their journey of weight loss and a healthy lifestyle.

What is Bariatric surgery?

Bariatric surgery is designed to reduce the stomach size and how food is digested, leading you to feel fuller after ingesting a small amount of food. This reduces your desire to eat and how often you feel hungry. But it is important to remember that surgery is only a tool to achieve weight loss and its success depends on other factors such as nutrition, exercise and behavior change.

Who benefits?

Bariatric surgery can be considered for both adults and adolescents. A thorough pre-operative assessment is required by your specialist and other health care professionals in your team to ensure your highest success.



Why consider Bariatric surgery?

Besides offering people with significant and sustained weight loss, bariatric surgery can provide multiple positive effects on your general health after surgery:

  • Long term remission for Type 2 Diabetes: Studies shows that between 45 to 95% of patients experience remission of type 2 diabetes due to the dramatic weight loss. Many of them are in total remission and no longer must use diabetic medications and can be insulin free.
  • Improvement of cardiovascular health: Bariatric surgery may improve blood pressure and reduce the risks of coronary heart disease and peripheral heart disease. Bariatric surgery can also help to prevent the risk of death associated with stroke, hypertension, and myocardial infarction.
  • Relief of depression: Obesity often leads people to depression and anxiety due to a decrease in self-esteem and poor body image. Weight loss through bariatric surgery enables people to become more social and active which improves their emotional health and can reduce depression.
  • Eradicate obstructive sleep apnoea: Reaching and maintaining a healthy weight has proven to be the success in the remission of Obstructive Sleep Apnoea. It is found to greatly improve post-surgery CPAP use, with a reduction of up to 75%.
  • Decrease joint pain: Obesity and excessive weigh impact patients’ weight bearing joints. Many people with weight issues experience joint pain and potentially joint impairment with the need for orthopaedic surgery. Weight loss following bariatric surgery has demonstrated being a major factor in reducing joint pain and improving function in patients suffering from hip and knee osteoarthritis.
  • Reduces infertility and issues during pregnancies: Bariatric surgery has a great impact on hormonal balance and sex drive. Males have an increase in sperm count and females, an increase chance in becoming pregnant. Weight loss can increase the success rate in assisted conception and reduces the risk of miscarriage, gestational diabetes, hypertension, macrosomia (large babies) and congenital abnormalities.

Differences in Procedures

In Australia three types of bariatric surgeries are performed, usually through laparoscopy or keyhole surgery being small cuts in the abdomen:

  • Lap band Surgery or gastric banding.
  • Gastric bypass or Roux-en-Y gastric bypass.
  • Gastric sleeve or sleeve gastrectomy.
