Abstract: Hemodialysis is one of the important treatment measures for end-stage diabetes patients with kidney disease. Diabetes patients treated with hemodialysis have significant blood glucose fluctuations，and maintaining stable blood glucose is one of the important strategies to improve the prognosis of patients. Conventional blood glucose testing methods such as self monitoring of blood glucose，glycated hemoglobin，and glycated albumin have certain limitations. The application of continuous blood glucose monitoring system for blood glucose is gradually being recognized，realizing the visualization of blood glucose fluctuations，which is beneficial for guiding treatment and improving patient prognosis.

Key words: continuous glucose monitoring, diabetes, hemodialysis, blood glucose fluctuations
