This study demonstrated the high frequency with which neuroglycopenic symptoms occur at the onset of hypoglycemia and the symptoms that could be used by an individual patient as a warning of the development of acute hypoglycemia, although the rapid reduction of plasma glucose is faster than experienced by the ambulant diabetic patient. Factor analysis assisted with the allocation of symptoms to either the autonomic or neuroglycopenic groupings, but the allocation of some symptoms remained undefined, and care must be taken when assessing symptoms such as hunger, weakness, blurred vision, and drowsiness when comparing the frequency of autonomic versus neuroglycopenic symptoms. To reduce the confusion resulting from the use of different symptom questionnaires in studies of hypoglycemia, a sample questionnaire is presented, the development of which was assisted by our analysis.
