CGM Skin Irritation: Prevention and Treatment Guide for Seniors

This article provides general information about CGM skin irritation treatment and is not medical advice. Always consult your healthcare provider about specific skin concerns or changes to your CGM routine.

Dealing with skin irritation from your continuous glucose monitor (CGM) can be frustrating and uncomfortable. As many as 40% of CGM users experience some form of skin reaction, but there are proven ways to prevent and treat CGM skin irritation treatment issues. Let’s walk through exactly what you can do to keep your skin healthy while using your CGM.

Understanding CGM Skin Reactions

Your skin might react to your CGM sensor in several ways:

• Redness around the sensor site
• Itching or burning sensation
• Small bumps or rash
• Dry, flaky patches

Most skin reactions are mild and can be managed at home. However, if you develop severe itching, swelling, or blistering, contact your doctor right away.

Simple Steps to Prevent CGM Skin Irritation

Let’s start with prevention – it’s easier to avoid skin problems than to treat them after they develop.

1. Proper Site Preparation

Before applying your sensor:

• Wash hands thoroughly with soap and water
• Clean the insertion site with plain alcohol (avoid scented products)
• Let your skin dry completely (count to 30)

Ask a family member to help if you have trouble seeing or reaching your sensor site. Many seniors find it helpful to use a mirror or ask a grandchild to assist with placement.

Effective CGM Skin Irritation Treatment Options

If you’re already experiencing irritation, here are gentle solutions:

Immediate Relief Steps:

• Apply a barrier wipe before sensor placement
• Try different approved adhesive products
• Rotate insertion sites more frequently

Medicare covers most CGM supplies, including approved barrier products. Contact your supplier at 727-831-3729 to check your coverage.

Common Causes of CGM Skin Irritation

1. Adhesive Sensitivity

The Problem: The sensor adhesive contains chemicals that some people’s skin doesn’t tolerate well.

The Solution:

• Use barrier sprays or wipes
• Try hypoallergenic overlay patches
• Switch to medical-grade adhesives
• Allow skin to breathe between sensors

2. Moisture Buildup

The Problem: Trapped moisture under the sensor creates irritation and promotes bacterial growth.

The Solution:

• Ensure skin is completely dry before application
• Use antiperspirant (aluminum-free) around site
• Apply thin layer of barrier film
• Change sensors if they get waterlogged

3. Mechanical Irritation

The Problem: The sensor rubbing against skin or clothing causes friction.

The Solution:

• Choose flatter body areas
• Wear loose-fitting clothes
• Use protective covers
• Secure edges with medical tape

4. Allergic Reactions

The Problem: True allergies to sensor materials, though less common.

The Solution:

• Consult allergist for testing
• Try different CGM brands
• Use prescription barrier creams
• Consider alternative monitoring methods
