Time in range (TIR) using continuous glucose monitoring (CGM) is vital for managing pregnant patients with type 1 diabetes. Further research is needed to establish its effectiveness for gestational diabetes and pre-pregnant type 2 diabetes.
Area of Science:
- Endocrinology
- Maternal-Fetal Medicine
- Metabolic Disorders
Background:
- Rising rates of adverse pregnancy outcomes linked to poor glycemic control necessitate improved blood glucose monitoring.
- Continuous glucose monitoring (CGM) offers dynamic glucose insights, leading to the development of Time in Range (TIR) as a key metric.
- International guidelines recognize TIR for type 1 diabetes in pregnancy, highlighting its superiority over traditional methods in reflecting glucose fluctuations and improving outcomes.
Purpose of the Study:
- To review the current research on Time in Range (TIR) in pregnant women.
- To highlight the potential of TIR as a critical indicator for blood glucose management in hyperglycemic pregnancies.
- To inform clinicians about the advancements in blood glucose monitoring for pregnant individuals with hyperglycemia.
Main Methods:
- Review of existing research on Continuous Glucose Monitoring (CGM) and Time in Range (TIR) in pregnancy.
- Analysis of the application and effectiveness of TIR in different diabetic pregnancy cohorts.
- Synthesis of current understanding regarding TIR's role in managing maternal hyperglycemia.
Main Results:
- TIR is established as an important blood glucose assessment method for pregnant patients with type 1 diabetes mellitus.
- TIR effectively overcomes limitations of conventional monitoring and improves maternal and neonatal outcomes.
- Limited clinical evidence currently exists for TIR's use in gestational diabetes mellitus and pre-pregnant type 2 diabetes mellitus.
Conclusions:
- Time in Range (TIR) is poised to become a critical indicator for blood glucose control in hyperglycemic pregnancies.
- Further clinical investigation is warranted to validate TIR's efficacy in gestational diabetes and pre-pregnant type 2 diabetes.
- Advancements in CGM technology are transforming glucose monitoring paradigms in high-risk pregnancies.
