The book is needed for several reasons. Bariatric surgery is one of the most clinically effective and cost effective services in any field of medicine, and is growing in popularity, and the non-specialist family practitioner, allied health professional and pharmacist need to know exactly what it involves. Bariatric surgery is in everyone’s interest – whether medic or patient, as it offers improvement in diabetes, heart disease, sleep apnoea, fatty liver and many cancers, whilst reducing benefits, housing costs and the general burden on the economy. There is a lot of flawed thinking on surgery in primary care, with only a minority of family practitioner specialists making the majority of referrals, whilst many are denying their patients access because of their own misconceived ideas. A ‘back to basics’ book will help tackle the negative views surrounding the topic, and improve the volume and quality of referrals. Very often patients turning up to obesity centres have been given poor advice, and inappropriate treatment, and arrive with little or no idea what to expect. Many medics prioritise other conditions first, overlooking the underlying cause, i.e. obesity. Basic education on obesity and co-morbidities is fast becoming essential.
