The ideal sensor insertion site for you may be based on your body type,
activity, sensitivities, and other personal and physical traits. You can
choose a site above or below your belt line. The best areas to insert
your sensor are usually flat and "pinchable." Avoid sensor insertion
where something may rub or press against the sensor. For example,
avoid sensor insertion along the waist band and seat belt strap, in or
near the belly button, on the upper buttocks near the waist/belt or too
low on the buttocks where you sit.
PRECAUTION
Avoid using the same spot repeatedly for sensor
insertion. Rotate your sensor placement sites, and
do not use the same site for two sensor sessions in
a row. Using the same site might cause scarring or
skin irritation.
• Choose an area at least 3 inches from your insulin pump infusion set
or injection site.
• You may need to shave the area where you plan to put the sensor so
the adhesive patch sticks securely.
• Make sure there are no traces of lotions, perfumes or medications on
the skin where you place the sensor.
For more help on ideal sensor insertion sites for you, contact your
healthcare professional.
