Preoperative Dietary Evaluation of the Bariatric Surgery Patient
As an essential member of the bariatric multidisciplinary team (MDT), the dietitian has a key role in assessing, evaluating and preparing the patient for bariatric surgery. Patients presenting for surgery generally have a long history of unsuccessful attempts at losing weight or in maintaining a clinically significant weight loss. Careful assessment and evaluation of the patient is essential to determine the current nutritional status, eating patterns, disordered eating, socioeconomic status and lifestyle, along with the patient’s understanding of the surgery and the anticipated results. This assessment will aid the MDT in assessing if the surgery is suitable for the patient. It will also assist in the preoperative planning and preparation, if surgery is scheduled.
This chapter covers the key points in the dietary and nutritional assessment and evaluation of the patient scheduled for bariatric surgery, including the preoperative blood tests and dietetic preparation of the patients for surgery.
