According to the latest reports from the International Diabetes Federation (IDF), the prevalence of diabetes among the population aged 65 and older is rising sharply every year. It has been revealed that 'Glucose Spikes'—sharp rises in blood sugar after meals—rather than just high fasting blood sugar, are a primary cause of cardiovascular incidents due to the impact they have on vessel walls.
In the past, diabetes management was a 'reactive' process involving finger pricks to check blood. However, modern IT technology in the form of CGM sensors collects blood sugar data every 5 minutes and transmits it to cloud servers. Even from a distance, children can receive immediate smartphone push notifications if their parents' blood sugar rises sharply or if they are at risk of hypoglycemia.
Online Medical Data Analysis: "Seniors often mistake symptoms such as thirst or lethargy as a normal part of aging, thereby missing blood sugar abnormalities. Automated biometric data monitoring through IT devices systematically blocks such human errors."
The key to preventing blood sugar spikes is transparency in ingredients. Health apps on smartphones scan for hidden sugars (such as high-fructose corn syrup) in processed foods based on global nutrition databases. Utilizing digital tools to read nutritional labels is the first step toward the most scientific dietary approach.

The paradigm of diabetes management is rapidly shifting from "fasting glucose numbers" to Glucose Variability (GV). The 2023 American Diabetes Association (ADA) guidelines formally introduced the concept of Time In Range (TIR) alongside traditional fasting glucose targets. TIR represents the percentage of a 24-hour period during which blood glucose stays between 70–180 mg/dL. Clinical data now consistently show that achieving TIR above 70% is associated with significantly reduced risk of retinopathy and nephropathy.
For seniors aged 65 and older, a particularly dangerous condition called Hypoglycemia Unawareness becomes increasingly common — where the body fails to produce the usual warning symptoms of low blood sugar. Research from the American Endocrine Society found that approximately 40% of diabetic patients over age 70 mistake hypoglycemic symptoms for simple fatigue or aging, missing critical intervention windows. The real-time alert system of CGM sensors represents the most effective technological countermeasure against this silent risk.
Among glucose variability metrics, the Coefficient of Variation (CV) should be maintained below 20%. Copenhagen Heart Study data indicates that patients with CV exceeding 36% face a 1.9-fold increased risk of major cardiovascular events compared to those within normal range. The true goal of diabetes management is not simply to lower glucose numbers, but to stabilize them — and continuous CGM monitoring with physician data sharing has become the new standard of modern diabetes care.
