Insulin Injection Site Adverse Effect in a Type 1 Diabetes Patient: An Unusual Presentation

Insulin is an integral part of Type 1 diabetes management. Patient education is of utmost importance to ensure proper injection technique for getting appropriate glycaemic control as well as to avoid injection site adverse effects. Commonest injection site adverse effect is lipodystrophy, attributable to localized manifestation of the pharmacological action of insulin. However, we present a case where incorrect injection technique led to an unusual presentation of injection site adverse effect. Apart from the abnormal skin changes, the incorrect technique also adversely affected the glycaemic control. Though less prominent, some marks are still evident one and a half years after correction of the injection technique. However, the glycaemic control has substantially improved. This emphasizes the need of proper patient education regarding insulin injection technique.
