Abstract

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 and metabolic surgery (BMS). 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 BMS and the anticipated results. This will aid the MDT in assessing if BMS is an appropriate treatment option 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 BMS, including the preoperative blood tests and dietetic preparation required.
