Nutritional Interventions Before & After Surgery



To maximise best outcomes from surgery we will assess  your current health, and investigate the presence of any medical conditions that could interfere with your outcomes. 

We offer personalised diagnostic tests to investigate your health, which helps to shape the personalised care plan around your weight loss surgery.

Once you have had your 3 initial consultations (bariatric surgeon, dietician and psychotherapist), a full set of blood tests will be taken and the results assessed. These along with your assessments usually lead to clearance for surgery. 

Occasionally something is picked up that may need further tests or opinions. Below are some of the conditions that might be discovered. Click on the boxes to find out more.

Example Of Diagnostic Test Explanations

We use diagnostic tests to assess various health markers and body functions.

These tests will only be requested if clinically required. They help your surgeon shape your clinical experience to make the surgery safer, and will support you in achieving better outcomes from surgery.

If you’ve had previous upper gastrointestinal surgery or even bariatric surgery, you will likely need a CT Scan and / or a Barium Swallow and / or Gastroscopy. 

CT Scan: A computerised tomography (CT) scan uses X-rays and a computer to create detailed images of the inside of the body.

Barium Swallow/Meal: a special type of X-ray test that helps your surgeon take a close look at the back of your mouth and throat, known as the pharynx, and the tube that extends from the back of the tongue down to the stomach, known as the oesophagus and stomach.

Gastroscopy (Upper GI Endoscopy): is a procedure where a thin, flexible tube called an endoscope is used to look inside the oesophagus, stomach and first part of the small intestine (duodenum), carried out under sedation.

Colonoscopy: is a test to check inside your bowels. This test can help find what’s causing your bowel symptoms. A long, thin, flexible tube with a small camera inside it is passed into your bottom, under sedation. You’ll be given a laxative the day before your colonoscopy, so your bowels are empty for the test.

Sleep Test: a sleep study, known as polysomnography, is a test used to diagnose sleep disorders. Polysomnography records your brain waves, the oxygen level in your blood, heart rate and breathing. This test is used to diagnose sleep apnoea.
