The role of comorbidities before and after bariatric surgery is not clear. The aims of this study are to determine whether there are any defining characteristics or comorbidities in patients attending the Comprehensive Metabolic Care Centre at the Royal Adelaide Hospital (RAH) who receive bariatric surgery and to determine any
changes in comorbidities from the time of referral to the time of surgery and 12/12 post surgery. We also wish to
determine any changes over time (using yearly intervals) that have occurred with bariatric surgery at the RAH looking
at total numbers of bariatric surgery, demographics and comorbidities. Patients who had bariatric surgery at
the RAH in the five year period from July 1, 2009 through to June 30, 2014 will be eligible for the study. The
surgeon’s database will be searched for patient descriptors and comorbidities including age, sex, BMI, Aboriginality,
weight (at referral, at last pre surgical appointment, on day of surgery and 12/12 post op), whether the patient has
any hernias, hypertension, diabetes mellitus, sleep apnoea, mental health issues, dyslipidaemia, kidney disease,
hypothyroidism, ischaemic heart disease, fatty liver, oesophageal reflux or asthma.
