Obesity management before and after pancreas transplantation

PURPOSE OF REVIEW

We provide a review on the incidence, consequences, and management of obesity in patients before and after pancreas transplant.

RECENT FINDINGS

Obesity is common in patients with both type 1 and type 2 diabetes. Obesity at the time of pancreas transplant is associated with worse graft and patient survival, while weight gain after transplant is associated with insulin resistance and posttransplant diabetes. Currently, lifestyle interventions are the backbone of obesity management and can improve insulin sensitivity, but result in only modest weight loss. Metabolic and bariatric surgery (MBS) offers the potential for substantial and durable weight loss. Laparoscopic sleeve gastrectomy is the procedure of choice and can be performed safely both before and after pancreas transplant. Antiobesity medications (AOMs) may also be effective, but concerns remain regarding determine the safety and efficacy when used in pancreas transplant recipients. More evidence is needed to guide the use of AOMs and MBS in pancreas transplant recipients.

SUMMARY

Lifestyle interventions, MBS, and AOMs each have a role in managing obesity after pancreas transplantation. In light of limited evidence and unique challenges in pancreas transplant patients, obesity management in pancreas transplant patients requires an individualized approach that leverages multidisciplinary expertise.
