In the case of administering insulin, what is the importance of rotating injection sites?

Rotating injection sites when administering insulin is crucial for promoting consistent absorption of the medication. Each injection site can have varying absorption rates due to differences in tissue thickness, blood flow, and the type of fatty tissue in the area. If the same site is used repeatedly, it can lead to lipodystrophy, which is the formation of scar tissue or lumps that can impair insulin absorption. By rotating injection sites, patients can help ensure that insulin is absorbed at a predictable rate, leading to more stable blood glucose levels.

While minimizing discomfort, preventing skin infections, and complying with hospital policies are important considerations in the administration of insulin, the primary purpose of site rotation is to maintain optimal insulin absorption and efficacy.
