There have been a number of clinically-relevant advances in diabetes, obesity, and metabolic syndrome emanating from gastroenterological research. Gastric emptying is a significant factor in the development of upper gastrointestinal symptoms. However, it is not the only mechanism whereby such symptoms occur in patients with diabetes. Disorders of intrinsic pacing are involved in the control of stomach motility in patients with gastroparesis; on the other hand, there is limited impact of glycemic control on gastric emptying in patients with established diabetic gastroparesis. Upper gastrointestinal functions related to emptying and satiations are significantly associated with weight gain in obesity. Medications used in the treatment of diabetes or metabolic syndrome, particularly those related to pancreatic hormones and incretins affect upper gastrointestinal tract function and reduce hyperglycemia and facilitate weight loss. The degree of gastric emptying delay is significantly correlated with the weight loss in response to liraglutide, a glucagon-like peptide-1 analog. Network meta-analysis shows that liraglutide is one of the two most efficacious medical treatments of obesity, the other being the combination treatment phentermine-topiramate. Interventional therapies for the joint management of obesity and diabetes mellitus include newer endoscopic procedures, which require long-term follow-up and bariatric surgical procedure for which long-term follow up shows advantages for individuals with diabetes. Newer bariatric procedures are presently undergoing clinical evaluation. On the horizon, combination therapies, in part directed at gastrointestinal functions, appear promising for these indications. Ongoing and future gastroenterological research when translated to care of individuals with diabetes mellitus should provide additional options to improve their clinical outcomes.Pages 180-18910 page(s)application/pdfenCreative Commons Attribution-NonCommercial 4.0 InternationalObesityGastric emptyingDiabetes mellitusGastric bypassBariatric surgeryWeight lossLAPAROSCOPIC SLEEVE GASTRECTOMYENERGY-EXPENDITURESINGLE-CENTERWEIGHT-LOSSASSOCIATIONGLP-1LIRAGLUTIDEDigestive DiseasesNutritionDiabetesPreventionMetabolic and endocrineCancerOral and gastrointestinalStrokeArticle2022-08-06https://doi.org/10.4239/wjd.v9.i11.180911Koch, Timothy [0000-0002-8026-9653]1948-9358
