The bariatric service at the Whittington Hospital is known as the North London Obesity Surgery Service (or NLOSS). The Whittington Hospital has been providing bariatric surgery since 1998 and is one of the most established providers of such services in the UK.
 
At NLOSS, we undertake Gastric banding, Roux-en-Y bypass (gastric bypass), Single Anastomosis Gastric Bypass and Sleeve gastrectomy as well as revision surgeries.  All operations are performed laparoscopically (keyhole surgery), which will help you to get up and around and back to normal very soon after surgery.
 
One of the mainstays of the NLOSS is our multidisciplinary team. Each team member has his or her own role and all together we ensure you are fully informed about weight loss surgery and that your operation is performed in the safest possible environment. Your safety is our first priority.

Bariatric Surgery Pathway Explained

 
Initial Appointment
At your initial assessment you will meet one of our members of the staff, this could be a surgeon, a registrar a specialist nurse or a dietitian.
At your initial appointment, you will be asked a great number of questions regarding your past medical, surgical history, weight management history, psychological wellbeing, eating behaviour and social circumstances.

Your clinician will order tests and investigations to help determine your suitability for surgery.  Most commonly ordered investigations are:

  • Blood Test
  • Oesophago-gastro-duodenoscopy (OGD)
  • Eating Disorder Assessment
  • Cognitive Behaviour Therapy (CBT)
  • Echocardiogram (ECHO) Electrocardiograph (ECG)
  • Sleep Study
  • Attend a virtual education session
  • Other necessary investigations or treatment – based on previous medical history

Having undergone your first assessment does not guarantee that you are a suitable candidate for bariatric surgery; suitability will be determined after the second appointment. 

Follow-up Appointment
After the initial assessment you will be invited to see your surgeon for the second time  approximately 4 – 6 moths later to review the result of the above investigation, which will determine if you are a suitable candidate for bariatric surgery.

After your second appointment the surgeon will do one of three things:

  1. List you for surgery
  2. Request further investigations
  3. Discharge you – if you are found to be unsuitable for surgery.
