Pharmacotherapy prevention and management of nutritional deficiencies post Roux-en-Y gastric bypass

Abstract

Roux-en-Y gastric bypass is the most commonly performed bariatric procedure. It is associated with nutritional deficiencies due to gastric reduction, intestinal bypass, reduced caloric intake, avoidance of nutrient-rich foods, noncompliance with supplementation and poor food tolerability. Although there are multiple publications on this topic, there is a lack of consistent guidance for the healthcare practitioner caring for the bariatric patient. This article will encompass literature reviewing the pharmacotherapy approach to prevention and management of nutritional deficiencies since the American Society of Metabolic and Bariatric Surgery guidelines were published in 2008.
