Type 2 Diabetes Remission: A Systematic Review and Meta-analysis of Nonsurgical Randomized Controlled Trials

Area of Science:

• Endocrinology
• Metabolic Diseases
• Clinical Trials

Background:

• Reversal of type 2 diabetes (T2D) remains challenging due to limited understanding and implementation of effective interventions.
• Evidence for T2D remission is growing but requires further investigation into core intervention components.

Purpose of the Study:

• To assess the impact of nonsurgical randomized controlled trials (RCTs) on achieving type 2 diabetes remission.
• To identify and characterize the core components of successful T2D remission interventions.

Main Methods:

• A systematic review and meta-analysis of randomized controlled trials (RCTs) published in MEDLINE and Embase up to April 2025.
• Included RCTs focused on multimodal pharmacological or nonpharmacological interventions for T2D remission in adults.
• Extracted data included study characteristics, clinical/population health outcomes, patient-reported outcomes, and adverse events.

Main Results:

• Multimodal interventions demonstrated a higher likelihood of achieving T2D remission (RR 1.75) compared to control groups.
• Nonpharmacological interventions showed a significantly higher remission rate (RR 5.80) than control groups.
• Intervention groups also showed significant improvements in HbA1c, weight loss, quality of life, and reduced hypoglycemia events.

Conclusions:

• Heterogeneity exists in studies regarding nonpharmacological components, intervention protocols, participant selection, and remission definitions.
• Tailored, strict protocols can induce T2D remission in newly diagnosed patients.
• Future research must address long-term sustainability, effectiveness, and patient preferences for T2D remission strategies.
