Description of intervention(s) / exposure
Patients presenting for obesity surgery who are at high risk of NASH by having all three of Type 2 diabetes or insulin resistance, hypertension and abnormal liver function tests (LFT) will undergo a 6 week program of weight loss finishing just prior to surgery using a VLCD (Optifast). Prior to VLCD intervention, biochemistry will be collected and a percutaneous liver biopsy and liver CT performed. Repeat measures of biochemistry and liver CT will be performed on completion of the VLCD course and the liver biopsy will be repeated during laparoscopy for the obesity surgery.
