Simple map may end painful insulin lumps for diabetes patients

This study tested a visual injection site map to help people with diabetes rotate where they inject insulin. The goal was to reduce lipohypertrophy—lumpy fatty tissue caused by repeated shots in the same spot—and improve blood sugar control. 170 adults on insulin for at least six months took part, with half using the map and half getting standard verbal advice. Over six months, researchers checked for lumps, how well patients followed rotation, and changes in HbA1c and blood sugar levels.
