Managing Your Blood Sugar levels

Published on: January 9, 2023


Globally there are around 537 million people living with diabetes,1 many of whom experience phases when blood sugar levels are too high, then too low. This variability can be challenging for people to manage and is associated with an increased risk of developing diabetes-related complications.2

A new standard: ‘Time in Range’ 

‘Time in Range’ (TiR) is the percentage of time that a person spends with blood sugar levels in their target range, complementing HbA1c as another important metric of blood sugar control, and can aid in understanding each individual’s response to balancing diet, daily activity and treatment.

The power of ‘Time in Range’ 

  • The time spent within your target blood sugar range 
  • A way to balance the impact of diet, activity and treatment 
  • Small improvements can be clinically meaningful for glycaemic control3,4 

At Sanofi, we believe it is time to think more about TiR, in efforts to help people living with diabetes increase the time they spend within their target blood sugar range. Small, incremental successes, for example a 5% increase in TiR, is associated with clinically significant benefits for individuals with type 1 or type 2 diabetes, and more daily TiR can help give people feelings of personal or therapeutic success.3,4 

Time-in-Range and glucose variability is now broadly recognized as a measure of glucose control by international experts and local guidelines such as the Advanced Technologies & Treatments for Diabetes (ATTD), the American Diabetes Association (ADA) and the European Association for the Study of Diabetes (EASD), and we are committed, via our clinical research programs, to contribute to the evolving evidence for the use of TiR as a key metric in diabetes management.5
