Understanding Blood Sugar Variability in Elderly HHS Patients

Te Pathophysiology of HHS in Older Adults

HHS is specifized by profound hyperglycemia, hyperosmolality, and dehydration in absence of signitant ketosis. In elderly individuals, the patogenesis is often multifactorial: stress- induced contrietatoria estates (cortisol, glucagon, catecholamines), relative insulin impapency, and expetioned gluconeogenesis from catobaboyc such ais infections or mycardial ention.

Blood sugar variability emerges from the interplay of these forces. For example, a patent may receive supplemental insulin boluses to correct hyperglycemia, only ty experience a rapid drop due te improwid to hydration or enhancanced insulin sensitivity during recovery. Conversele, a missed dose of oral hypoglycemic agent or an insiversistent reduction in fluid intake can send glucose levelsoaring.

In hospital- based geriatric units, glycemic variability is independently associated with longer length of stay, increaged incidence of infections, and higher 90- day interity.
