Closed-Loop Insulin System Improves Glucose Control in Pregnant Women with Type 1 Diabetes: JAMA

Closed-Loop Insulin System Improves Glucose Control in Pregnant Women with Type 1 Diabetes

A recent study published in JAMA, the CIRCUIT trial, found that pregnant women with type 1 diabetes who used a closed-loop insulin delivery system had improved glucose control.

The study, conducted in Canada, showed that women using the closed-loop system spent more time within the pregnancy-specific glucose range, with less time above or below targets, and had lower average glucose and HbA1c levels compared to those receiving standard care.

The randomized CIRCUIT trial demonstrated significant benefits of closed-loop insulin delivery in pregnant women with type 1 diabetes.
