Metabolic Obesity Service

The MLHD Metabolic Obesity Service (MOS) offers a pathway to bariatric (weight loss) surgery, through education and support, focussing on lasting behaviour change. 

Obesity is a complex, chronic, relapsing condition and is unlikely to benefit from a 'one size fits all' approach. 

The management of obesity requires a team approach with ongoing support and monitoring. The MOS team offer this through individualised recommendations from our qualified health professionals to achieve the best opportunities for health improvement.



Why would you choose Bariatric Surgery?

Compared with non-surgical approaches like diet and exercise, there is international consensus that bariatric surgery is by far the most effective intervention for sustained weight loss and improvements in obesity related health conditions. 

Surgery is irreversible, and is a tool to manage obesity and improve health and wellbeing.

What to Expect

Initially you will attend an information session where you will learn about our service, the surgery, expectations and an opportunity to ask questions.

From here you elect to see the MOS Doctor for suitability and planning.

MOS uses a combination of virtual appointments and face to face. This can help you remain in touch with us without the inconvenience for some of losing a day to travel and interrupting work and home life. (You can read more about Virtual Care on our site).

The appointment phases are:

  • Phase 1 - Appointment with the team, weekly workshops in small groups
  • Phase 2 - Putting new skills into practice, monthly appointments with MOS team. Ability to demonstrate behaviour change, up to 12 months.
  • Phase 3 - When the MOS team and you agree, proceed to surgical consultation.
  • Phase 4 - Post surgical follow-up, support and coaching for at least 2 years.

Commitment to all phases is essential for long term weight loss and long term improvement to your health.

Weight loss through surgery is not easy. It requires commitment and hard work. The team are here to support you through all phases of the program.    

The MOS will help you identify barriers to behaviour change to support you to improve your health and quality of life.
