Diabetes management before, during, and after bariatric and metabolic surgery.

Overview

Metabolic surgery is unrivaled by other therapeutic modalities due to its ability to foster diabetes remission. Metabolic surgery is an integral therapeutic modality in obese and morbidly obese populations because pharmacological and behavioral therapy often fail to effectively manage type II diabetes. However, given the invasiveness of the metabolic surgery relative to behavioral therapy and the need to conform to preparatory and discharge guidelines, patients must adhere to strict nutritional and diabetes management protocols. Also, the pharmacological regimen that is instituted upon discharge is distinct from the preoperative regimen. Oftentimes, the dose for insulin and oral medications are significantly decreased or withdrawn. As time elapses and depending on several factors (e.g., exercise adherence), diabetes control becomes tenuous in a small portion of the patients because there is weight regain and on-going beta cell failure. At this time interval, intensification of diabetes therapy becomes prudent. Indeed, pharmacotherapy from the preoperative to the postoperative phase is labile and may be complex. Therefore, by discussing pharmacology options during the preoperative, perioperative, and postoperative period, the goal is to guide clinician-driven care.
