Sensor Site Bruising – Qingmu

Questions This Article Can Answer

Bruising at the sensor application site may occur for several reasons:

Cause	Explanation
Anticoagulant medications	Certain medications may increase the likelihood of bruising, such as aspirin and heparin.
Capillary damage during insertion	It cannot be ruled out that bruising may occur due to minor damage to capillaries during sensor application. Generally, this will recover on its own after some time.
Impact or prolonged pressure	Bruising may result from accidental impact during wear or prolonged pressure (e.g., unconsciously pressing on the sensor while sleeping), which can cause capillary bleeding under the skin at the sensor edge. This typically resolves on its own.
Vitamin deficiency	In some cases, vitamin deficiency may contribute to bruising. Accompanying symptoms may include insufficient sleep, poor mental state, loss of appetite, weight loss, and general weakness.

In most cases, bruising does not affect sensor operation. We recommend continuing to wear the sensor and monitor the site.

If bruising occurs without other symptoms: Continue wearing and observe the area.
If bruising is accompanied by increasing discomfort or pain: Remove the sensor and seek medical advice.
If you experience any abnormalities with the device: Please contact us for further assistance.
