ABSTRACT
Introduction: Hypoglycemia is a frequent event in
patients with diabetes mellitus (DM). When the
reduction is severe and prolonged blood glucose can
cause brain damage manifested by memory and/or
cognitive impairment, dementia and brain death. The
mechanisms involved in hypoglycemic neuronal death
are varied and have as a common element the
oxidative stress, which suggest that the greatest
neuronal damage does not occur during the period
of hypoglycemia, but possibly during glucose
replacement.
Case report: We report the case of a
diabetic patient with hypoglycemia associated with
prolonged diarrhea syndrome and hyporexia, who
progressed to coma and death.
Conclusions: The main
limiting factor in the management of type 1 and 2
DM is hypoglycemia. Brain death secondary to severe
reduction in blood glucose levels is rare, but it must
be considered in patients with risk factors for
prolonged hypoglycemia, due to the association with
altered nutritional status, heart failure, kidney or liver
disease, neoplasia, infection or sepsis. Knowledge of
the mechanisms leading to neuronal death during
glucose replacement, force us to be cautious after
an episode of hypoglycemia, which avoid severe
complications and even death.
