A Guide to Preventing "Compression Lows" From Your CGM

Compression lows, also known as hypoglycemic events, are a serious concern for individuals with diabetes who wear Continuous Glucose Monitors (CGMs). These events can occur when the sensor on your CGM is compressed, causing it to inaccurately read low blood sugar levels. In this article, we will provide you with a comprehensive guide on how to prevent compression lows from your CGM.

What Causes Compression Lows?

Before we dive into the prevention methods, it's essential to understand what causes compression lows. The main cause is the compression of the sensor on your CGM, which can be caused by various factors such as:

  • Wearing tight clothing that constricts the sensor
  • Sitting or sleeping on the sensor
  • Engaging in activities that cause pressure on the sensor, such as working out or playing sports
  • Using adhesive bandages or tape that are too tight

How to Prevent Compression Lows

To prevent compression lows from your CGM, follow these simple steps:

1. Choose the Right CGM

When selecting a CGM, look for one that is designed to minimize compression lows. Some CGMs have features such as flexible sensors or adjustable straps that can help reduce pressure on the sensor.

2. Wear Your CGM Correctly

Wearing your CGM correctly is essential to preventing compression lows. Make sure the sensor is placed in the correct location, and the straps or adhesive are not too tight.

3. Avoid Tight Clothing

Wearing tight clothing that constricts the sensor can cause compression lows. Choose loose-fitting clothing that allows the sensor to breathe.

4. Be Mindful of Your Activities

If you engage in activities that cause pressure on the sensor, such as working out or playing sports, take regular breaks to check your CGM and adjust the sensor if necessary.

5. Use Adhesive Bandages or Tape with Caution

When using adhesive bandages or tape, make sure they are not too tight, and do not cover the sensor. If you need to use bandages or tape, choose ones that are specifically designed for use with CGMs.

6. Monitor Your CGM Regularly

Regularly monitoring your CGM can help you identify potential compression lows before they become a serious issue. Check your CGM at least once a day, and adjust the sensor as needed.

7. Keep Your CGM Clean and Dry

Keeping your CGM clean and dry is essential to preventing compression lows. Wash your CGM with soap and water, and dry it thoroughly after each use.

8. Replace Your CGM as Needed

Replace your CGM as recommended by the manufacturer. Worn-out or damaged CGMs can cause inaccurate readings, which can lead to compression lows.

9. Seek Medical Attention if Necessary

If you experience a compression low, seek medical attention immediately. While most compression lows are not life-threatening, they can still cause serious health complications if left untreated.

10. Stay Informed

Stay informed about the latest developments in CGM technology and best practices for preventing compression lows. Attend seminars, workshops, or online forums to learn from experts and other individuals with diabetes.
