Diabetes Dialogue: 2026 AACE Guidelines for Type 2 Diabetes

Welcome back to Diabetes Dialogue: Technology, Therapeutics, & Real-World Perspectives!

On March 17, 2026, the American Association of Clinical Endocrinology (AACE) released a consensus statement, which features an algorithm for the management of type 2 diabetes (T2D) in adult patients.1

In this episode of Diabetes Dialogue, cohosts Diana Isaacs, PharmD, and Natalie Bellini, DNP, review the newly released 2026 American Association of Clinical Endocrinology (AACE) type 2 diabetes treatment algorithm, positioning it as an evolution of the 2023 update that integrates a growing body of clinical trial evidence into a more comprehensive, complications-focused framework. They emphasize a paradigm shift away from glucose-centric management alone, highlighting the importance of addressing comorbidities, including cardiovascular disease, chronic kidney disease, obesity, obstructive sleep apnea, and metabolic dysfunction–associated steatotic liver disease (MASLD), as central to optimizing outcomes.

The discussion outlines the guideline’s structure, including its 10 guiding principles, which reinforce lifestyle intervention as foundational, promote individualized glycemic targets (with a preference for A1c ≤6.5% when safely achievable), and strongly encourage early use of continuous glucose monitoring (CGM). The hosts underscore the emphasis on avoiding therapeutic inertia, minimizing hypoglycemia risk, and managing cardiometabolic comorbidities alongside glycemia as part of routine care.

A key highlight is the introduction of a diabetes classification algorithm aimed at reducing misdiagnosis, particularly distinguishing type 1 from type 2 diabetes and identifying less common etiologies. Within this framework, the guidelines newly prioritize screening for hypercortisolism, informed by findings from the CATALYST trial, which demonstrated a higher-than-expected prevalence among patients with difficult-to-control diabetes. Isaacs and Bellini note that recognizing and treating underlying hypercortisolism may significantly improve glycemic control and, in some cases, reduce the need for diabetes-specific therapies.

The episode further reviews updated algorithms for cardiovascular risk reduction, dyslipidemia, and hypertension, emphasizing aggressive, individualized targets and the continued central role of lifestyle modification. Pharmacologic recommendations reflect robust recent evidence, prioritizing SGLT2 inhibitors and GLP-1 receptor agonists (including dual GIP/GLP-1 agents) for patients with cardiorenal or metabolic comorbidities, while also incorporating emerging indications such as heart failure with preserved ejection fraction and MASLD.

Isaacs and Bellini also discuss the guideline’s glucose-centric algorithm for patients without major comorbidities, highlighting patient-centered decision-making based on factors such as hypoglycemia risk, weight considerations, and cost/access. They reinforce recommendations for early combination therapy when A1c is significantly above target and appropriate use of insulin, including guidance on avoiding overbasalization and incorporating prandial strategies.

The conversation concludes with commentary on the guideline’s practical strengths, including clear visual algorithms, concise format, and detailed pharmacotherapy tables summarizing efficacy, safety, and organ-specific benefits. The hosts emphasize that the updated AACE algorithm provides clinicians with an actionable, evidence-based roadmap for delivering holistic, individualized diabetes care that extends beyond glycemic control to address the full spectrum of cardiometabolic risk.
