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

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.

Bariatric surgery pharmacy consultation service.

Bariatric surgical patients often need changes in formulation and dosages of their medications. The literature contains minimal information regarding pharmaceutical care and consultation services for the bariatric surgery patient. Complex medication regimens and safety concerns initiated a collaborative effort between surgeons and pharmacists to manage more effectively bariatric patients perioperatively. The consultation service included patient identification, pharmacy referral, pharmacist consultation with the patient, communication of recommendations with surgeons, follow-up, and documentation. There were 124 consultations performed from February 2, 2009 to December 1, 2010 with an average of 7.7 medications optimized per patient. Every patient required a minimum of one adjustment to their regimen. The surgeons approved 98% of these recommendations. Of recommendations provided, the majority focused on changing the formulation of the medication in some manner. The collaborative effort between surgeons and pharmacists effected changes in medication transitioning perioperatively and resulted in improved pharmaceutical care for this patient population.
