Continuous glucose monitors (CGMs) have transformed diabetes care by providing real-time glucose readings without the need for frequent finger pricks. However, many users experience discomfort, skin irritation, or sensor failures when using the most common CGM sites. If you’re looking for pain-free and more comfortable alternatives, you’re in the right place.
Let’s explore seven alternative CGM sites that may offer better comfort, improved accuracy, and enhanced wearability for your diabetes management.
Why Consider Alternative CGM Sites?
The most common CGM placement areas—such as the upper arm or abdomen—work well for many, but they are not ideal for everyone. Reasons to explore alternative CGM sites include:
- Pain or Discomfort – Some areas are more sensitive than others, making CGM insertion painful.
- Skin Sensitivities – Reactions like rashes, redness, or adhesive allergies can cause irritation.
- Sensor Adhesion Issues – Sweaty, active lifestyles can lead to sensors falling off prematurely.
- Scar Tissue or Bruising – Repeated use of the same area can cause scarring, affecting sensor accuracy.
- Personal Comfort & Preference – Some people find certain locations more comfortable or less noticeable.
Finding the right alternative CGM site can make diabetes management easier and less intrusive. Now, let’s look at seven placement options that could improve your CGM experience.
1. Thighs – A Hidden & Comfortable Option
Best For:
People who want a discreet location with minimal interference from clothing or movement.
The thigh is an excellent alternative to traditional CGM sites, particularly for those who find abdominal placements uncomfortable. The front or outer thigh provides a good amount of soft tissue, allowing for better absorption of interstitial fluid (which is what CGMs measure).
Tips for Success:
- Place the sensor on the upper or outer thigh where there is some fat.
- Avoid the inner thigh to prevent rubbing from clothing.
- If you’re active, use strong adhesive to keep the sensor secure.
Considerations:
- Can be affected by movement, especially during running or workouts.
- Some users report slight variations in readings due to muscle activity.
2. Lower Back – Great for Sleepers
Best For:
Those who sleep on their sides or find abdomen placements uncomfortable.
The lower back (above the buttocks) offers a hidden and pain-free placement option. Since this area has a decent fat layer and minimal muscle movement, sensors stay secure and comfortable.
Tips for Success:
- Place the CGM just above the buttocks, near the love handle area.
- Choose an area with some fat for better accuracy.
- Ideal for people who sit for long periods since there’s less friction.
Considerations:
- Harder to reach without assistance.
- Adhesive may need reinforcement due to clothing friction.
3. Upper Buttocks – A Less Irritated Site
Best For:
Kids, athletes, and anyone who experiences skin irritation in traditional areas.
Placing the CGM on the upper part of the buttocks provides a low-movement, soft-tissue option that can be particularly helpful for children and active individuals. This area is less prone to accidental bumps and typically offers great sensor adhesion.
Tips for Success:
- Works well with high-waisted clothing for extra protection.
- Consider using a flexible overlay patch to ensure strong adhesion.
- Avoid placing directly where you sit to prevent pressure-related discomfort.
Considerations:
- Can be tricky to insert without a mirror or assistance.
- May be less ideal for those who frequently wear tight clothing in this area.
4. Forearm – A Surprising but Effective Choice
Best For:
Individuals looking for an alternative to upper arm placements.
The forearm isn’t a traditional CGM site, but many users find it comfortable and effective. With proper sensor placement, it can provide consistent readings and is easy to access for insertion and maintenance.
Tips for Success:
- Choose the outer forearm where there’s some fat and minimal muscle movement.
- Avoid placing too close to the elbow to prevent interference.
- Ideal for those who frequently wear short sleeves.
Considerations:
- Some users report variations in readings compared to traditional sites.
- May not work as well for those with very lean arms.
5. Calf – Ideal for Active Individuals
Best For:
Athletes and those who struggle with adhesion in upper-body placements.
The calf provides a unique alternative for CGM wearers who need a location that stays secure during workouts or daily activities. The lower leg area has some soft tissue, making it a viable option for many.
Tips for Success:
- Place on the outer or back part of the calf where there is some fat.
- Secure with an overpatch, especially if sweating is an issue.
- Great for those who wear longer socks or leggings to help with adhesion.
Considerations:
- Can be uncomfortable for those with very muscular calves.
- May have slight variations in readings due to increased blood flow in legs.
6. Side of the Chest – A Low-Interference Spot
Best For:
Those who want a low-contact area that avoids pressure from sleeping positions.
The side of the chest, near the ribcage or below the armpit, is another excellent CGM site for those looking for comfort and stability. It’s a lesser-known spot but offers reliable readings with minimal interference.
Tips for Success:
- Choose a location with some fat to help the sensor sit securely.
- Works well for those who wear loose clothing.
- Offers a discreet placement under tank tops or bras.
Considerations:
- Can be affected by body hair, requiring extra preparation.
- Some users find the chest area less comfortable due to occasional sensor pressure.
7. Upper Shoulder – A Secure & Easy-to-Reach Location
Best For:
Those who need easy sensor placement and excellent adhesion.
The upper back of the shoulder is a fantastic alternative for people who experience discomfort with abdominal or arm placements. Since the shoulder has some soft tissue, the sensor can stay secure without excessive movement.
Tips for Success:
- Place slightly below the shoulder blade for comfort.
- Works well with tank tops or loose shirts.
- Use a mirror or ask for assistance to insert correctly.
Considerations:
- Can be harder to reach for self-application.
- May not work well for those who frequently carry backpacks or shoulder bags.
Final Thoughts
Exploring alternative CGM sites can greatly improve comfort, reduce irritation, and enhance long-term wearability. If you struggle with pain, sensor failures, or skin reactions, switching to a different placement may be the key to a better experience. Each person’s body responds differently, so experimenting with various sites can help you find the most comfortable and effective option. Using additional adhesive, rotating placements, and choosing areas with adequate fatty tissue can improve sensor security and accuracy.
To keep your skin healthy and prevent scarring, it’s essential to rotate CGM sites regularly and avoid using the same spot repeatedly. If you’re unsure about a new placement, consult your doctor or diabetes educator for guidance. By finding a site that works best for you, glucose monitoring can become a pain-free and stress-free part of your routine, allowing you to focus on living well with diabetes.
