What are common sites for insulin injection?

The common sites for insulin injection are primarily areas of the body with a subcutaneous fat layer, allowing for better absorption of the medication. The abdomen and outer thighs are among the most recommended sites. The abdomen, in particular, is preferred because it tends to have a consistent absorption rate for insulin and allows easy access. The outer thighs are also effective due to the sufficient subcutaneous tissue present.

Using alternative areas like joints and bones or less suitable areas such as cankles and wrists does not provide optimal absorption or may cause discomfort. Similarly, injecting in the navel area and groin could pose risks such as affecting blood vessels or nerves, as well as inconsistent absorption. Thus, the abdomen and outer thighs are the best choices for insulin injection, ensuring both safety and effectiveness in managing blood glucose levels.
