Which practice helps prevent tissue changes from repeated insulin injections?

• A. Always inject in the same spot
• B. Rotate injection sites
• C. Mix insulin types before injection
• D. Massage the site after injection

Answer: (B)

Rotating injection sites protects the subcutaneous tissue from repeated trauma, which can lead to lipohypertrophy or lipodystrophy—areas of thickened or lumped tissue that alter how insulin is absorbed. When injections land in the same spot over time, the tissue doesn’t heal well and absorption becomes unpredictable, causing blood glucose swings. By using a systematic rotation across different sites (and moving them within a region so you don’t jab the exact same spot each time), you give tissue time to recover and promote more consistent insulin absorption. The other actions don’t prevent tissue changes and can even worsen absorption: sticking to one spot keeps injuring the same tissue, mixing insulins isn’t about tissue health, and massaging after injection can change how quickly insulin enters the bloodstream.
