Analysis and perspective: comparison of insulin diluent leakage post-injection using two different needle lengths and injection volumes in obese patients with type 1 or type 2 diabetes mellitus

The effects of needle gauge and length on the efficacy and tolerability of insulin injection therapy are becoming better understood. This analysis discusses some of these effects and comments on a new study by Ignaut and Fu in this issue of Journal of Diabetes Science and Technology on the effects of needle length on insulin diluent leakage from injection sites.
