Upper GI & General Surgery

We get it. Surgery is a big decision, but sometimes it’s the right one. Not only for your health but also for your general wellbeing.

So you’ve been referred to Dr Balalis for surgery, but it’s not related to weight loss? You’re still in the right hands.

In addition to his passion for supporting people on their weight loss journeys, Dr Balalis is a multi-faceted surgeon, having trained nationally and internationally with several world-renowned surgeons.

His surgical specialties include bariatric, upper gastrointestinal and general. All of which he routinely performs from Calvary Adelaide Hospital.


Upper GI issues include any problem of the oesophagus or stomach. Common upper GI conditions include gastro-oesophageal reflux, hiatus hernias, cancer, achalasia and other motility disorders.

Dr Balalis provides a holistic and complete upper GI service, including surgery, endoscopic options (such as per oral endoscopic myotomy procedures for achalasia sufferers), pH and manometry testing, and specialised advice on lifestyle modifications and other factors.

He has a Masters Degree in Oesophageal Cancer, frequently publishes peer-reviewed journals and is active in extending research in the upper GI field.


Dr Balalis performs many general surgeries, including gallbladder and hernia repairs as well as gastroscopy and colonoscopy procedures.

He also offers ongoing support to patients of other surgeons, following post-surgical complications.
