An evaluation of the bariatric surgical patient

Abstract

Obesity continues to be one of the most common prevalent chronic diseases worldwide with recent data stating that it has now reached global pandemic proportions making it a major public health problem. In 2008 the World Health Organisation (WHO) stated that worldwide around 1.4 billion adults were overweight (body mass index [BMI] 25.0-29.9 kg/m2) and a further 500 million were obese (BMI ?30 kg/m2). Of note, the prevalence of obesity has tripled in Europe over the last 30 years with around 50% of the population in the majority of European countries being overweight or obese.1-4 Locally, the situation is also alarming with data from the European Health Interview Survey (EHIS) in 2011 stating that Malta had the highest rate of obese males in Europe (24.7%) and when it comes to females, Maltese women were the second most obese after British women (21.1% and 23.9% respectively).5 Even more worrisome is the fact that Malta also tops the charts for the highest prevalence of overweight and obesity in school-aged children thus accentuating the fact that urgent action needs to be taken in order to tackle effectively this world-wide epidemic.6 Unfortunately obesity is strongly linked to several co-morbid conditions such as type 2 diabetes, hypertension, cardiovascular disease, dyslipidaemia, obstructive sleep apnoea, non-alcoholic steatohepatitis, osteoarthrosis, as well as some cancers (including breast, ovary, prostate, endometrium and colon) and psychiatric illnesses and thus it stands to reason that an increase in prevalence of obesity has also led to an increase in prevalence of these co-morbidities resulting in an impaired overall quality of life and decreased life expectancy in these subjects.
