Severe Hypoglycemia in Older Adults with Type 1 Diabetes: A Study to Identify Factors Associated with the Occurrence of Severe Hypoglycemia in Older Adults with T1D.

Principal Investigator

Andrew Ahmann

Study Purpose

The T1D Exchange has a registry of more than 25,000 individuals with type 1 diabetes (T1D). Information collected in the registry shows that severe low blood sugars occur more commonly in older adults who have had T1D for a long time. This study is being done to try to find out why that might be. In particular, we want to see if we can find out ways that severe low blood sugars could be prevented.
