Abstract
Bariatric surgery is becoming increasingly more common for the treatment of morbid obesity. Preoperative weight loss leads to decreases in the size of the liver and the amount of intra-abdominal fat, which improve the surgical field and therefore the operative times and complication rates as well. Well-planned dietary advancement ensures proper healing from the surgery and develops life-long healthy eating habits. The recommended postoperative diet starts with soft food and gradually advances to solid food. Bariatric surgery has the potential to cause a variety of nutritional and metabolic complications, which are mostly due to the extensive surgically-induced anatomical changes incurred by the patient's gastrointestinal tract. Counseling, monitoring, and nutrient and mineral supplementation are essential for treatment, and dietary intake and eating behavior after bariatric surgery should also be changed to achieve long-lasting success. Structured nutritional counseling can help weight reduction and maintenance.
