This qualitative study examined adults’ recollections of their reactions to their diabetes diagnosis and explored the similarities and differences among those diagnosed with type 1 versus type 2 diabetes. Based on semistructured interviews, the authors identified three themes: 1) shared emotional reactions of fear, sadness, confusion, and worry; 2) perceived differences in expressing concerns for diabetes complications; and 3) differences in perceiving the diagnosis as a surprise versus an inevitability. How health care professionals deliver diabetes diagnoses may be crucial to individuals’ acceptance of the condition and coping strategies. HCPs should consider assessing people’s emotional reactions to their diagnosis.
