Background
Goal: To identify mechanisms, treatment, & preventative
strategies for hypoglycemia in type 2 diabetes.
Phase 1 translational research (aka “clinical research”).
Rate of severe events vary: 60-170 per year.
Hospitalizations cost between $200M - $1B per year.
Retrospective studies identify age, fasting, sulfonylurea
usage, polypharmacy, and intercurrent illness as risk
factors for severe hypoglycemia.
