Hello, I'm Wang Zhihong, a national second-class nutritionist. Vice President of Changsha Health Management Society has been engaged in diabetes health teaching, education and nutritionist training for over 0 years.

There are skills in measuring blood sugar, which can make you feel no pain and leave no scars.

First, wash your hands with warm water and neutral soap, not alcohol. The blood collection pen has a scale of 1-5, which represents the acupuncture depth. To get an appropriate depth, generally choose 3. Press your finger for at least one minute after blood collection, and do not leave any bleeding spots. Don't draw blood at the fingertips, just on both sides, because there are many nerve endings at the fingertips and fewer on both sides, which can reduce the pain.
