Auricular Acupuncture for Lowering Blood Glucose in Type 2 Diabetes: A Pilot Study

Although type 2 diabetes mellitus (T2DM) is a major health epidemic, little research on auricular acupuncture for reducing blood glucose levels has been published. In Guatemala, where this study was conducted, the prevalence of T2DM is high and access to care is limited. The purpose of this pilot study was to determine if an auricular acupuncture protocol could be a feasible, effective treatment for reducing blood glucose, thus offering another potential accessible treatment.

Utilizing a self-controlled design approach, 28 participants diagnosed with T2DM were recruited and received 2 weeks of treatment consisting of a set protocol of 5 points in each ear. Pre- and post-treatment surveys were used to assess patients' health status, treatment expectations, and quality of life. Paired t-tests were used to measure pre- to post-treatment glucose levels.

Treatment produced significant reduction in the patients' fasting and postprandial blood glucose levels, averaging 45.35 (n = 19; P = 0.014) and 109.45 points (n = 10; P = 0.008), respectively. Surveys indicated that all participants would be interested in using the treatment again to help manage their blood glucose.

An auricular protocol may provide a low-cost, effective treatment for lowering blood glucose in patients with T2DM. The results of this study are promising, suggesting that further investigation is warranted.
