📖About Continuous Glucose Monitoring
Continuous glucose monitoring (CGM) uses a small sensor worn on the skin, usually on the arm or abdomen, to measure glucose levels in the interstitial fluid every few minutes, providing a detailed picture of blood sugar trends throughout the day and night. Unlike traditional finger-prick testing, which offers only isolated snapshots, CGM reveals patterns such as post-meal spikes, overnight lows, and the impact of exercise or stress on glucose levels. This data helps patients and physicians fine-tune diet, medication and insulin dosing with much greater precision. It is increasingly used by both type 1 and type 2 diabetics seeking tighter glucose control and fewer hypoglycaemic episodes.
