About Obesity and Bariatric Surgery

   
 

Obesity is a complex condition with physical, social, and psychological implications. It can affect virtually all age and socioeconomic groups. The world we live in is very obesogenic – our foods have become very high in calories and our environments makes physical activity challenging.

Research has shown that our bodies don’t like us losing and weight and will try to defend against changing. The concept that the body weight stays stable despite changes in diet and energy expenditure is known as the body weight “set-point”. Surgery is a useful tool to help reset the body weight “set-point”.

Bariatrics is a branch of medicine that specializes in the causes, prevention, and treatment of obesity. Bariatric surgery is a major procedure and a life-altering event. The surgery intentionally alters your gastrointestinal tract to facilitate weight-loss. This weight loss is significant and is usually associated with substantial improvements in obesity related illnesses such as diabetes and sleep apnoea.

Expected Outcomes

  • Weight loss – 20-30%
  • Diabetes – 60% chance of remission
  • Hypertension – 50% chance of remission
  • Fatty Liver – 80% chance of remission
  • Sleep Apnoea – 50% chance of remission

The Bariatric Surgery Journey

   
 

The actual operation is only part of your weight management journey. A team of specialised health professionals will support you before, during and for three years after your surgery.

The team consists of:

  • a registered nurse
  • registered dietitian
  • psychologist
  • anaesthetist
  • bariatric surgeon
  • your GP

Before your surgery you will be working with the members of the team to prepare you for your surgery and on-going lifestyle changes. A treatment plan will be formulated alongside you. This will require your attendance at a number of clinic appointments and education sessions. It is compulsory to attend all appointments.

Prior to your operation you will need to undergo some medical investigations including a gastroscopy. You will also require blood tests both pre and post-surgery.

In the weeks prior to your surgery you will be prescribed a liquid diet (Opti-fast®). It is crucial that you keep to this diet prior to your operation as the purpose of the diet is to shrink your liver size and reduce the fat around your stomach. If the diet is not maintained surgery may not be possible.

 

  

Life after Surgery

   
 

The Bariatric Team will continue to support you after your surgery. You cannot fully control how much weight you lose after surgery. Focus on the behaviour changes that you can control for your best health and well-being.

Regular follow-up appointments and blood tests continue after your surgery particularly in the first year.  You will also be required to take lifelong vitamin supplements. 

Follow up continues for 3 years after your surgery.
