Evaluación nutricional en pacientes candidatos a cirugía bariátrica: estudio del patrón nutricional y prevalencia de deficiencias nutricionales antes de la cirugía en un centro de referencia

The nutritional deficiencies observed in the obese group which is a candidate for obesity surgery could be due to following unbalanced, excessively restrictive and/or uncontrolled diets that they have been on during several periods of their lives until they came for surgical treatment. They could also be related to the lack of dietetic-nutritional education, social factors, the existence of food behaviour disorders or diseases associated with obesity. It is important to detect and correct these altered parameters before surgery, for after it has been performed (BPG) there is an increase in these deficits.
