If you’re feeling overwhelmed by constant beeps and vibrations from your continuous glucose monitor (CGM), you’re not alone. Many seniors experience
CGM alert fatigue seniors often report, which can make managing diabetes more stressful than it needs to be. Let’s explore simple ways to make your CGM work better for your lifestyle.
Understanding CGM Alert Fatigue in Seniors
CGM alert fatigue happens when you receive so many alerts that you start ignoring them or feeling stressed by them. This is especially common for seniors who may be new to diabetes
technology or managing multiple medical devices.
What you need to know: Not every alert needs immediate attention. We’ll help you identify which alerts are most important and how to adjust others for peace of mind.
Simple Steps to Reduce CGM Alert Fatigue
1. Personalize Your Alert Settings
Your CGM comes with pre-set alerts, but these settings aren’t one-size-fits-all, especially for seniors.
Pro Tip: Ask your healthcare provider about adjusting alert ranges specifically for your needs as a senior. Many older adults can safely have wider target ranges than younger people.
- High glucose alert: Consider setting this slightly higher initially
- Low glucose alert: Work with your doctor to set this at a safe but not too sensitive level
- Rate of change alerts: You might not need these as often as younger users
2. Create Quiet Times
Most CGMs allow you to set specific times when alerts are less frequent or silent, except for urgent low glucose warnings.

Setting Up Your Ideal Alert Schedule
Morning Hours (6 AM – 9 AM)
Recommended Settings:
- Keep low alerts active
- Reduce high alert sensitivity
- Turn off rise rate alerts during breakfast
Why: Morning glucose naturally rises; frequent alerts during this time can be discouraging.
Daytime Hours (9 AM – 6 PM)
Recommended Settings:
- Standard alert ranges
- Enable fall rate alerts
- Keep vibration on
Why: You’re active and need awareness without disruption.
Evening Hours (6 PM – 10 PM)
Recommended Settings:
- Slightly relaxed high alerts
- Maintain low alerts
- Reduce repeat alerts
Why: Dinner and relaxation time shouldn’t be constantly interrupted.
Nighttime (10 PM – 6 AM)
Recommended Settings:
- Essential alerts only
- Louder low glucose alerts
- Extend snooze time for highs
Why: Quality sleep is crucial; only urgent alerts should wake you.
Which Alerts You Can (and Can’t) Silence
Alerts You CANNOT Turn Off:
- Urgent Low (below 55 mg/dL) – For your safety
- Sensor errors – Need immediate attention
- Transmitter issues – Affects all readings
Alerts You CAN Customize:
- High glucose levels
- Low glucose (above 55)
- Rise and fall rates

Smart Strategies from Fellow Seniors
Margaret, 72:
“I set my high alert at 250 instead of 180. My doctor agreed that for my age and health, this prevents constant beeping while still warning me of serious highs.”
Robert, 69:
“I turned off prediction alerts completely. They made me anxious about things that might not even happen. Now I just focus on actual numbers.”
Dorothy, 75:
“My granddaughter helped me set different alert sounds. Low glucose plays a loud tune, while high glucose is just a gentle chime. It helps me know what’s happening without looking.”
