Optimal glycemic control reduces surgical complications in diabetes patients

A study analyzed the impact of glycemic control on surgical outcomes in 502,478 patients, revealing that diagnosed diabetes and Hba1c levels significantly influence postoperative complications. While undiagnosed prediabetes correlated with lower surgical risks, undiagnosed diabetes increased medical complications. Notably, those with very low and high Hba1c levels faced more complications, with moderate control (Hba1c 7-8%) deemed optimal. The findings highlight the importance of preoperative screening and personalized diabetes management to improve surgical outcomes.
