Why is the abdomen the preferred site for subcutaneous insulin injections?

• A. Closest to the heart
• B. Best for rotation
• C. Largest surface area with fastest absorption
• D. Most comfortable

Answer: (C)

Where you inject insulin affects how quickly it enters the bloodstream. The abdomen provides a large, well-vascularized area with relatively thin subcutaneous tissue, which leads to faster and more predictable absorption than other sites. The sizable surface area also makes it easier to rotate injections, helping prevent lipodystrophy and keeping injections convenient for self-administration. Although comfort and accessibility matter, the main reason this site is favored is the combination of a large surface area and reliable, rapid absorption.
