A study presented at the ENDO 2025 conference by researchers from the University of Southern California suggests that social isolation significantly increases the risk of developing diabetes and experiencing poor blood sugar control in older adults. This finding highlights a potentially underestimated factor in metabolic health.
The research involved analyzing data from nearly 4,000 Americans aged 60 to 84, originally collected as part of the 2003–2008 National Health and Nutrition Examination Survey (NHANES). After accounting for other known risk factors, the study revealed a strong correlation: older individuals who reported experiencing social isolation—defined by factors like infrequent social contact, lack of support, or living alone—were found to be 34 percent more likely to have diabetes. Furthermore, they were 75 percent more likely to have issues with blood sugar levels compared to their peers who were not socially isolated.
This study is noteworthy as one of the first large-scale investigations to establish a clear link between social isolation and disturbances in carbohydrate metabolism. While biological and behavioral causes of diabetes have been the primary focus for clinicians, these results indicate that loneliness and lack of social connection should be considered a significant, potentially modifiable risk factor.
The authors emphasize the critical implications of this finding, especially in the context of an aging global population and the rising prevalence of loneliness, which has been particularly amplified by recent global events like the pandemic. They argue that healthcare providers should recognize social isolation as an important marker of risk. Promoting and supporting social connections among older adults could therefore play a vital role not only in enhancing their overall quality of life but also in reducing the likelihood of developing serious metabolic diseases like diabetes.

In a separate area of research related to diabetes treatment, scientists recently announced a breakthrough in therapy for type 1 diabetes using stem cells. This experimental treatment reportedly enabled the majority of participants to regain their body`s ability to produce insulin, significantly reducing or potentially eliminating their dependence on daily insulin injections.
