To provide an updated review of the fear of hypoglycemia (FOH) literature published from 2016 to 2025, in youth with type 1 diabetes (T1D) and their caregivers. The Hypoglycemia Fear Surveys (HFS) are the most used questionnaires to assess FOH in studies conducted in the United States and internationally. The factor structure of the Parent and Child versions of the HFS have been updated to better reflect only maladaptive aspects of managing FOH. Diabetes technology studies routinely include the HFS to assess FOH as a secondary outcome. Only two randomized clinical trials (RCT) to reduce FOH have been conducted with youth with T1D and their caregivers. FOH is a common psychological complication occurring in youth with T1D and their caregivers. More research is needed to update the HFS to reflect modern T1D self-management and test interventions that aim to reduce FOH in RCTs.
