At Nutrisense, we're all about helping you achieve your health goals! A key part of that journey is ensuring your glucose monitor provides accurate and consistent readings. This starts with optimizing your sensor placement.

##   

## Site Selection & Skin Preparation

_Choose the right location and prepare your skin properly for optimal sensor adhesion and accuracy._

*   **Select the Right Spot:** Choose an area on the back of your upper arm that has the most fatty tissue. Ensure the skin is intact and free from irritation.
*   **Avoid Muscle Areas:** Do your best to avoid placing the sensor too close to muscles. This can lead to discomfort and, in some cases, even slight bleeding upon insertion.
*   **Clean Skin is Key:** Always apply the sensor to clean, dry skin. If you have naturally oily skin, a gentle exfoliation beforehand can help. Simply use rubbing alcohol to thoroughly clean the chosen area, then wait for it to air dry completely before inserting the sensor.
*   **Hair Management:** If the area where you plan to apply the sensor has a lot of hair, consider shaving a small section. This can help prevent discomfort when it's time to remove the sensor.

## Placement Strategy & Rotation

_Rotate placement sites and consider your daily activities for comfortable, long-term wear._

*   **Allow for Healing:** Give previous insertion sites at least one week to fully heal before placing another sensor in the exact same location. To facilitate this, remember to alternate arms with each new sensor placement.
*   **Consider Your Sleep:** Think about your typical sleeping positions when choosing a sensor spot. If you're a side sleeper, select an area that won't be pressed or bothered while you sleep.

## Environmental & Lifestyle Considerations

_Account for humidity, activity levels, and environmental factors that affect sensor performance._

*   **Avoid Humidity:** Do not apply the sensor immediately after showering or in a steamy bathroom. When possible, dry the area thoroughly with a hairdryer or apply the sensor in a dry environment. This practice significantly helps the sensor and its adhesive patch adhere better to your skin.
*   **Active Lifestyles:** For those with active lifestyles or who sweat frequently, consider using a skin protection barrier like **Skin Tac wipes** or **Skin-Prep wipes** before applying the sensor.
