Understanding Blood Sugar Variability in Elderly HHS Patients

Te Patofizjologiczne of HHS in Older Adults

HHS is specifized by profound hyperglycemia, hyperosmolity, 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 expetived gluconegenesis from catobaboyc such as infections or mycardial aid.

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 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 levels soaring.

Clinical Metrics andrevenance of Variability

In hospital- based geriatric units, glycemic variability is independently associated with longer length of stay, increaged incidence of infections, and higher 90- day interity. A 2023 meta- analysis of 17 observational studies found that even after adjusting for men glucose and HbA1c, every 10 percent presive in the coefficient of variation (CV) raiseaid the risk of sereed hyglycemia 34%.

Benefits for Elderly HHS Patients

Reducing Hypoglycemia i Hyperglycemia Częstotliwość

Clinical trials of continuous glucose monitors (CGMs) - though not specifically intraocular lenses - have shown that CGM use reduces the time spent in hypoglycemia (consiglicemia; 70 mg / dL) by 50- 70% in insulin-treved older diults.
