Which area is NOT recommended for insulin injections?

The middle of the abdomen is not recommended as a site for insulin injections due to the increased potential for variability in absorption rates and the risk of accidentally injecting into muscle or deeper tissue layers. The most effective and commonly recommended injection sites for insulin are those that are muscle-sparing and have a consistent absorption rate. The back of the arms, outer thighs, and abdomen are preferred areas because they typically provide a layer of fat where insulin can be absorbed more evenly.

Injecting insulin in the middle of the abdomen may also lead to discomfort or bruising, particularly if there is any tension in the area or if the injection technique is not ideal. Furthermore, any scar tissue or post-injection reactions can further complicate consistent insulin absorption in that area. Thus, selecting sites that are less prone to these issues is critical for optimal insulin management.
