Which population requires tighter monitoring for hypoglycemia risk when using sulfonylureas or insulin?

• A. Young adults
• B. Pregnant women
• C. Older adults
• D. Athletes

Answer: (C)

Older adults are more susceptible to hypoglycemia from sulfonylureas or insulin because aging changes how the body handles these medications and how it regulates glucose. Kidney and liver function often decline with age, slowing drug clearance and prolonging effects, so a dose can cause longer-lasting low glucose. They also frequently have multiple health conditions and take several drugs that can interact or heighten hypoglycemia risk. Irregular meals, decreased appetite, or social factors can create mismatches between insulin or secretagogue action and intake. Cognitive impairment or frailty can blunt the ability to recognize symptoms or respond quickly, and counterregulatory responses to low glucose may be diminished, making hypoglycemia more dangerous. With these combined factors, tighter monitoring—more frequent glucose checks, cautious dose adjustments, and consideration of regimens with lower hypoglycemia risk—is typically warranted for older patients. In other groups, while hypoglycemia can occur, these complicating factors are less prominent, so the emphasis on ultra-tight monitoring is not as pronounced.
