Dexcom Continuous Glucose Monitoring
Dexcom continuous glucose monitoring (CGM) systems track glucose levels throughout the day and night, sending readings to a receiver or compatible smart device. Zahrun stocks genuine Dexcom supplies with fast, discreet U.S. shipping.
How CGM Works
A small sensor sits just under the skin and measures glucose in the fluid between cells. A transmitter sends those readings wirelessly to a display device — a dedicated receiver, smartphone, or compatible smartwatch — so you can see your current level and how it's trending, rather than a single point-in-time result.
System Components
- Sensor & applicator: the sensor is inserted with a one-push applicator and worn for a set number of days.
- Transmitter: clips into the sensor and sends readings to your display device.
- Receiver or app: displays real-time readings, trend graphs, and customizable high/low alerts.
Why People Choose CGM
Continuous readings and trend arrows show not just where glucose is but where it's heading, and customizable alerts can warn of highs and lows. Many systems also allow sharing data with family or care partners.
