● Rotation Flexibility: The stomach provides a larger surface area, allowing users to rotate placement sites, minimizing skin fatigue and irritation.
● Challenges of Stomach Placement
● Sleep Discomfort: For those who sleep on their stomachs, having a sensor there might cause discomfort.
● Clothing Concerns: Tight-fitting clothing, belts, or waistbands might exert pressure on the sensor, potentially affecting readings.
Can you put a CGM on your stomach?
Certainly. The lower abdominal area, specifically below the waist but above the groin, is ideal. It’s recommended to place the sensor at least 3 inches away from the belly button to avoid areas with denser nerve endings.
The 20 Rule for Dexcom G6
The Dexcom G6, like many continuous glucose monitors (CGMs), operates based on specific principles to ensure accurate readings. One such principle that users often come across is the “20 rule.” But what exactly is this rule, and how does it relate to sensor placement?
What is the 20 Rule for Dexcom G6?
The “20 rule” for Dexcom G6 refers to the accuracy range of the device. In simpler terms, if your Dexcom G6 reads 100 mg/dL for your blood glucose, the actual reading can be anywhere from 80 mg/dL to 120 mg/dL – a 20% range above or below the displayed number. This rule is crucial for users to understand, especially when making treatment decisions based on CGM readings.
Relevance to Sensor Placement
Accurate readings are the cornerstone of any CGM device, and the Dexcom G6 is no exception. The placement of the sensor plays a pivotal role in ensuring that readings fall within this 20% accuracy range. While the arm and stomach are both FDA-approved locations, ensuring the sensor is placed flat against the skin without any folds or obstructions is vital. Proper placement minimizes the chances of readings falling outside the 20% range, ensuring users get the most accurate data possible.
For those who are integrating their Dexcom G6 with insulin pumps, understanding this rule becomes even more critical. Our guide on how to connect Dexcom G6 to the Tandem pump offers insights into ensuring seamless integration while maintaining accuracy.
Other Recommended Placement Areas for Dexcom G6
While the arm and stomach are popular choices for many Dexcom G6 users, it’s essential to understand that the device offers flexibility in terms of placement. The key is to find a spot that ensures accurate readings while maximizing comfort and convenience.
Where is the best place to put Dexcom G6?
The ideal placement for the Dexcom G6 sensor varies from person to person, depending on factors like body type, daily activities, and personal comfort. However, the manufacturer’s guidelines recommend the following areas:
1- Upper Buttocks: Especially recommended for children aged 2 to 17. This area offers a good amount of subcutaneous fat, which can help in getting consistent readings.
2- Lower Back: An area that’s often overlooked but can be suitable for many, especially if they want to give their usual sites a break.
3- Thighs: Some users find the outer thigh to be a comfortable spot, especially if they have more fatty tissue in that area.
It’s essential to avoid placing the sensor over areas with tattoos, scars, or any skin abnormalities, as these can interfere with the sensor’s ability to measure glucose levels accurately.
