Pathophysiology of Bariatric Surgery: Metabolism, Nutrition, Procedures, Outcomes and Adverse Effects uses a metabolic and nutritional theme to explain the complex interrelationships between obesity and metabolic profiles before and after bariatric surgery. The book is sectioned into seven distinct areas, Features of Obesity, Surgical Procedures, Nutritional Aspects, Metabolic Aspects, Diabetes, Insulin Resistance and Glucose Control, Cardiovascular and Physiological Effects, and Psychological and Behavioral Effects. Included is coverage on the various types of bariatric surgery, including Roux-en-Y gastric bypass, gastric banding, sleeve gastrectomy, biliopancreatic diversion, and jejunoileal bypass, as well as the variations upon these procedures.

Rajkumar Rajendram

Dr Rajkumar Rajendram is a clinician scientist with a focus on internal medicine, anaesthesia, intensive care and peri-operative medicine. He graduated with distinctions from Guy’s, King’s and St. Thomas Medical School, King’s College London in 2001. As an undergraduate he was awarded several prizes, merits and distinctions in pre-clinical and clinical subjects.

Dr Rajendram began his post-graduate medical training in general medicine and intensive care in Oxford. He attained membership of the Royal College of Physicians (MRCP) in 2004 and completed specialist training in acute and general medicine in Oxford in 2010. Dr Rajendram subsequently practiced as a Consultant in Acute General Medicine at the John Radcliffe Hospital, Oxford.

Dr Rajendram also trained in anaesthesia and intensive care in London and was awarded a fellowship of the Royal College of Anaesthetists (FRCA) in 2009. He completed advanced training in regional anaesthesia and intensive care. He was awarded a fellowship of the Faculty of Intensive Care Medicine (FFICM) in 2013 and obtained the European diploma of intensive care medicine (EDIC) in 2014. He then moved to the Royal Free London Hospitals as a Consultant in Intensive Care, Anaesthesia and Peri-operative Medicine. He has been a fellow of the Royal College of Physicians of Edinburgh (FRCP Edin) and the Royal College of Physicians of London (FRCP Lond) since 2017 and 2019 respectively. He is currently a Consultant in Internal Medicine at King Abdulaziz Medical City, National Guard Heath Affairs, Riyadh, Saudi Arabia.

Dr Rajendram’s focus on improving outcomes from Coronavirus Disease 2019 (COVID-19) has involved research on point of care ultrasound and phenotypes of COVID-19. Dr Rajendram also recognises that nutritional support is a fundamental aspect of medical care. This is particularly important for patients with COVID-19. As a clinician scientist he has therefore devoted significant time and effort into nutritional science research and education. He is an affiliated member of the Nutritional Sciences Research Division of King’s College London and has published over 400 textbook chapters, review articles, peer-reviewed papers and abstracts.
