Type 2 Diabetes Mellitus, Bariatric Surgery, Lifestyle Intervention, Obesity, Systematic Review


Obesity, with coexisting T2DM, is difficult to treat successfully for various reasons and carries enormous health risks and financial burdens. The purpose of this systematic review is to compare outcomes of conventional medical treatment to bariatric surgery for the treatment of T2DM, and determine which patients may be appropriate for referral. Data Sources: An electronic search of the literature was conducted to identify studies from 2008 to 2014 in the following databases: CINAHL, National Library of Medicine PubMed®/MEDLINE®, EBSCO, SciVerse®, Springer Link®, and the Cochrane library. Conclusions: Bariatric surgical options, even before weight loss occurs, positively affect glucose homeostasis and in some bariatric procedures and individuals with particular characteristics, produce considerable weight loss and remission of diabetes. Positive correlates were younger age, shorter disease duration, and BMI >30 kg/m2. Secondary outcomes are also improved. The same effects are seldom realized through conservative methods. Results/Implications for Practice: All obese patients should be referred for intensive intervention, with the minimum goal of 10% weight loss. Under certain circumstances, referral for bariatric surgery should be considered, particularly for individuals with BMI >40 kg/m2, or BMI ≥35 kg/m2 and at least one obesity related co-morbidity. Others may be considered on a case-by-case basis.-by-case basis.


The College of Nursing showcases some of our best evidence based scholarly papers from graduate students in the Family Nurse Practitioner Program. The papers address relevant clinical problems for advance practice nurses and are based on the best evidence available. Using a systematic approach students critically analyze and synthesize the research studies to determine the strength of the evidence regarding the clinical problem. Based on the findings, recommendations are made for clinical practice. The papers are published in professional journals and presented at professional meetings.
