Why does my FreeStyle Libre keep beeping?

Answered by James Kissner

The FreeStyle Libre system is designed to help individuals monitor their blood sugar levels continuously and conveniently. One of the features of this system is the ability to set up alarms to alert you when your sugar levels are either too high or too low. These alarms can be quite helpful in managing your diabetes effectively.

Now, let’s address the question of why your FreeStyle Libre keeps beeping. There can be a few reasons for this:

1. Low or high glucose alarm: If you have set up your FreeStyle Libre to sound an alarm when your sugar levels go below a certain threshold (low alarm) or above a certain threshold (high alarm), the device will beep to notify you. This is a beneficial feature as it ensures that you are aware of any significant fluctuations in your glucose levels and can take appropriate action.

2. Sensor expiration reminder: The FreeStyle Libre sensors have a limited lifespan, usually around 14 days. Once a sensor reaches its expiration date, the reader may beep to remind you that it’s time to replace the sensor. It’s essential to adhere to the recommended sensor replacement schedule to ensure accurate readings and reliable alarms.

3. Sensor error or malfunction: Occasionally, the FreeStyle Libre system may encounter sensor errors or malfunctions. These errors can result in false alarms or constant beeping. If you consistently experience this issue, it’s advisable to contact the manufacturer’s customer support for assistance. They can guide you through troubleshooting steps or provide a replacement if necessary.

It’s important to note that the beeping sound comes from the FreeStyle Libre reader, not the sensor itself. The sensor is responsible for continuously measuring your glucose levels, while the reader displays the readings and provides alarm notifications. You have the option to choose whether you want the reader or your phone to sound the alarms when setting up your preferences.

In my personal experience, I have found the alarms on the FreeStyle Libre system to be quite effective in alerting me to any significant changes in my glucose levels. The beeping sound serves as a helpful reminder to check my readings and take appropriate actions, such as adjusting my insulin dosage or consuming a snack to raise my blood sugar.

To summarize, your FreeStyle Libre may keep beeping due to low or high glucose alarms, sensor expiration reminders, or sensor errors. It’s crucial to pay attention to these alarms as they play a vital role in managing your diabetes effectively. If you encounter persistent issues with false alarms or malfunctions, reach out to the manufacturer’s customer support for assistance.
