Glucose Sensors 101: How Continuous Monitoring Helps You Navigate Holiday Meals and Avoid Highs and Lows
The holiday season brings joy, celebration, and plenty of delicious food. For people living with diabetes, it can also bring unpredictable blood sugar swings. That’s where glucose sensors, also known as continuous glucose monitors (CGMs), come in.
These small, wearable devices provide real-time glucose readings, helping you stay in control even when your plate is full of festive favorites. Whether you’re newly diagnosed or supporting a loved one, understanding how continuous monitoring works can make a big difference during the holidays and beyond.
What Is a Continuous Glucose Monitor (CGM)?
A continuous glucose monitor (CGM) is a device that tracks your blood sugar levels around the clock. Instead of relying on fingersticks, CGMs use a tiny sensor placed under the skin, usually on the arm or abdomen, to measure glucose in the interstitial fluid.
That sensor sends data to a receiver or smartphone app, displaying your glucose trends in real time.
Key Features of CGMs:
- Real-time alerts for highs and lows
- Trend arrows showing whether glucose is rising, falling, or steady
- “Time-in-range” tracking to help you stay within your target zone
- Data sharing with caregivers, family members, or healthcare providers

Why CGMs Matter During the Holidays
Holiday meals tend to be high in carbohydrates and sugar, which can cause sharp glucose spikes. A CGM helps you see exactly how your body responds to different foods, so you can make smarter choices, without missing out on the celebration.
How a CGM Can Help During Holiday Eating:
- Track glucose levels before, during, and after meals
- Spot patterns from traditional dishes like stuffing, pie, or sweet potatoes
- Make simple swaps, such as pairing carbs with protein or fiber, to reduce spikes
- Avoid surprises from alcohol, stress, or lack of sleep
Even small changes, like choosing lean proteins or adding vegetables, can help keep glucose levels steady. With real-time alerts, you’ll know when it’s time to take action, before a high or low becomes a problem.
Understanding “Time-in-Range” and Alerts
Time-in-range refers to the percentage of time your glucose stays within your target zone (typically 70–180 mg/dL). The more time you spend in range, the better your overall glucose control and long-term health.
CGMs Also Include:
- High and low alerts to warn you when levels go outside your range
- Urgent low soon alerts to help prevent severe drops
- Customizable thresholds for personalized control
These features are especially valuable during busy holiday events, when your usual schedule, meals, and activity level may change.

Tips for Using Your CGM During the Holidays
- Check your sensor placement before travel or parties to ensure comfort and adhesion.
- Pack extra supplies like sensors, wipes, snacks, and chargers.
- Use your CGM as a guide, not a restriction, to enjoy your favorite treats in moderation.
- Stay active! A short walk after meals can help lower glucose levels.
- Monitor alcohol carefully, if you drink, pair beverages with food and keep an eye out for delayed lows.
Is a CGM Right for You or a Loved One?
CGMs are now available for many people with type 1 or type 2 diabetes, including those using insulin or oral medications. Some models are even available over the counter, offering easier access to real-time glucose tracking.
