Key Takeaway
Consider mindfulness interventions as an adjunct to improve HbA1c and psychological health in diabetes, but note study heterogeneity.

This meta-analysis pooled data from randomized controlled trials involving 1,987 individuals with diabetes mellitus (942 in the intervention group, 955 in controls) to assess the effects of mindfulness-based interventions (MBIs) on glycemic control and psychological outcomes. The primary outcome was HbA1c, and secondary outcomes included stress, anxiety, and depression.

The analysis showed a statistically significant improvement in HbA1c with MBIs compared to controls (Hedges' g = 0.564; 95% CI 0.221 to 0.908; p = 0.001). Larger effect sizes were observed for psychological outcomes: stress (g = 1.132; 95% CI 0.551 to 1.714; p < 0.001), anxiety (g = 1.321; 95% CI 0.569 to 2.072; p = 0.001), and depression (g = 1.059; 95% CI 0.564 to 1.555; p < 0.001).

The authors noted several limitations, including heterogeneity in MBI format, variation in intention-to-treat analysis and concealed allocation, attrition differences, and funding source variations. The lack of a priori analysis was also acknowledged. Adverse events and follow-up duration were not reported.

While these results suggest potential benefits of MBIs for both glycemic and psychological outcomes in diabetes, the limitations caution against overinterpretation. Clinicians may consider MBIs as an adjunctive approach, but further high-quality, standardized trials are needed.

A large review of studies looked at how mindfulness-based interventions affect people living with diabetes. The researchers analyzed data from nearly 2,000 participants to see if these mental health practices could impact physical markers like HbA1c levels, as well as emotional states.

The findings showed that those who practiced mindfulness saw improvements in their blood sugar levels compared to the group that did not. Additionally, the study reported significant improvements in feelings of stress, anxiety, and depression among participants with diabetes. These results suggest that mindfulness might be a helpful tool for both physical and mental health.

Because this was a large review of many different studies, there were several variations in how the programs were taught. The findings are promising, but they do not replace standard medical care. Patients should talk to their healthcare team to see if adding a mindfulness program is right for their specific treatment plan.

What this means for you:
Mindfulness may help people with diabetes improve blood sugar levels and reduce feelings of stress or anxiety.

Common questions

Can mindfulness help my blood sugar?

The study found that mindfulness-based interventions were linked to improvements in HbA1c levels for people with diabetes. While this shows a positive link between the practice and blood sugar management, you should consult your doctor to see how it fits into your specific medical plan.

Does mindfulness help with the stress of having diabetes?

Yes, the study reported significant improvements in stress, anxiety, and depression for those who used mindfulness-based interventions. These results suggest that these programs may help improve the emotional well-being of people living with diabetes.

Is it safe to try a mindfulness program?

The study did not report any specific safety concerns or adverse events for those participating in mindfulness programs. However, you should always speak with your healthcare provider before starting any new therapy to ensure it is appropriate for your health needs.

We synthesized the effects of MBIs on psychological outcomes and HbA1c in diabetic patients and conducted subgroup analyses to investigate the sources of heterogeneity. Nine electronic databases were methodically explored from their inception through May 2025. We reviewed studies on the outcomes for individuals with diabetes mellitus who participated in mindfulness-based interventions. A random-effects model was employed to calculate the effect size. The funnel plot, Q statistics, and I2 were employed to assess heterogeneity among studies. Across 24 primary studies (N = 1987), 942 participants engaged in mindfulness-based interventions and 955 functioning as controls. Mean age ranged from 18.3 to 66.3 years. Overall, mindfulness-based interventions showed improvement of HbA1c (Hedges' g = 0.564, 95%Confidence interval, CI, 0.221, 0.908, p = 0.001), stress (g = 1.132, 95%CI 0.551, 1.714, p < 0.001), anxiety (g = 1.321, 95%CI 0.569, 2.072, p = 0.001) and depression (g = 1.059, 95%CI 0.564, 1.555, p < 0.001). MBI format, intention-to-treat analysis, concealed allocation, attrition, funding sources, and a priori analysis were modifiers affecting the effect size. To sum up, mindfulness-based therapies markedly improved HbA1c levels and psychological outcomes, among individuals with diabetes mellitus. Future studies with robust designs are warranted. Healthcare professionals may consider using these therapies to improve psychological outcomes and HbA1c levels in individuals with diabetes mellitus.
