Glycemic Control and Osteohealth in Adults Living With Type 1 Diabetes
Recruiting now
Conditions studied: Type 1 Diabetes
In brief
Bone damage is frequently observed in type 1 diabetes, and hyperglycemia is associated with an increased risk of fracture. This pilot study in 25 people living with type 1 diabetes aims to determine whether the introduction of an automated insulin delivery (AID) system improves bone markers through rapide optimization of glycemic control. Measurements will be taken before the start of AID, 2 months and 4 months afterwards.
