Why is it important for insulin injection sites to be rotated?

The importance of rotating insulin injection sites primarily relates to the prevention of lipodystrophy, which can significantly affect insulin absorption. When insulin is injected into the same site repeatedly, it can cause fat tissue to become lumpy or pitted, a condition known as lipodystrophy. This can lead to unpredictable insulin absorption, where insulin may not work effectively due to changes in the fatty tissue in that area.

Consistent absorption of insulin is essential for maintaining stable blood glucose levels. Rotating injection sites helps ensure that the insulin enters an area of healthy tissue that can absorb it properly, promoting better overall glycemic control. Therefore, rotating injection sites is crucial not only for effective diabetes management but also for maintaining the integrity of tissue and ensuring that insulin continues to be absorbed as intended.
