First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a new map for insulin injection sites (either digital or paper) could reduce skin lumps caused by insulin. 170 adults with diabetes who had been using insulin for at least six months took part. The map helped people rotate injection spots, aiming to improve blood sugar control and prevent skin problems.
