Weight-reducing diabetes medications increase fall risk in patients with type 2 diabetes

Tsukuba, Japan—Patients with low skeletal muscle mass are at a higher risk of falling. Certain diabetes medications, particularly SGLT2 (SGLT2) inhibitors and GLP-1 (GLP-1) receptor agonists, are associated with weight reduction, which may contribute to muscle mass loss and, consequently, an increased risk of falls. To explore this association, researchers investigated the impact of diabetes medications on fall risk in patients with type 2 diabetes.

The study involved a longitudinal follow-up of 471 patients (median age: 64 yr) who were admitted to the Department of Endocrinology, Diabetes, and Metabolism at the University of Tsukuba Hospital. Following their discharge, annual fall-related questionnaire surveys were conducted for up to 5 yr. The researchers reported a fall incidence rate of 17.1 falls per 100 person-years.

A detailed analysis identified three significant risk factors for falls: a history of falls at the time of hospitalization, the use of SGLT2 inhibitors at discharge, and advanced age. While GLP-1 receptor antagonists alone did not significantly influence fall risk, the combination of SGLT2 inhibitors and GLP-1 receptor antagonists resulted in a higher incidence of falls compared with SGLT2 inhibitors monotherapy.

These findings underscore the importance of monitoring fall risk in patients prescribed SGLT2i, particularly those also receiving GLP-1RA. Healthcare providers should implement appropriate dietary and exercise interventions to mitigate muscle loss and reduce fall risk following hospital discharge in patients with type 2 diabetes.
