Description of intervention(s) / exposure
Therapeutic venesection in non-alcoholic steatohepatitis study participants who have iron overload.

'Visit 1 (Screening) - Obtain informed consent - Inclusion and exclusion criteria - Record medical history including alcohol, dietary and lifestyle - Return within 2 weeks

Visit 2( Baseline-month 0) - Inclusion/exclusion criteria - Physical examination including vital signs, waist and hips measurement - Alcohol and lifestyle questionnaires - Fasting blood test, urine sample - Dietary and lifestyle counselling - Ferriscan - Randomisation

Visit 3 (month 3- for both groups) - Physical examination including vital signs, waist and hips measurement - Alcohol and lifestyle questionnaires - Fasting blood test, urine sample - Dietary and lifestyle counseling Visit 4 (month 18- for both groups) - Physical examination including vital signs, waist and hips measurement - Alcohol and lifestyle questionnaires - Fasting blood test, urine sample - Dietary and lifestyle counseling - Liver biopsy - Ferriscan Liver biopsy and Ferriscan will be performed in two major tertiary teaching hospitals. For the venesection (intervention) group: - Visits will be initially scheduled for 1 month after randomisation, then 3 monthly if necessary - Fortnightly venesection until serum ferritin level is <50 ug/L - Skip one session of venesection if anaemia (Hb <115g/L (female) <135g/L (male) - Further maintenance on a three monthly basis or as frequently as required to keep ferritin level <50ug/L - Iron studies will be performed prior to each venesection - Vital signs and any adverse events will be recorded at each visit.

Duration of each visit:
Visits 1, 2, 3 and 4 (final visit)- between 1- 1.5 hours.

Ferriscan visits- 1 hour

Venesection visits- This can varies between one hour or more depending if there are any adverse events post venesection.

Standard dietary and lifestyle counselling- advice will be given at each visit by the research nurse who is experienced in counselling type 2 diabetics and NAFLD patients, on a generally low fat and low glycaemic index diet, and regular exercise of moderate to high intensity of minimal 60-90 minutes a day. The session will be of approximately 30 minutes duration.

Period of overall intervention is 18 months
