Lipohypertrophy is reported ubiquitously in insulin-treated people with type 2 diabetes, displaying an average frequency of 47%, up to a maximum of 75%, and subtly causing severe disabling consequences.

Its mere presence is proof of a lack of educational activities by the care team.

In doctors from general and diabetic hospital wards, awareness of the importance and metabolic consequences of lipohypertrophy appears to be poor.

Educational deficiencies on correct injection practice have also been documented among nurses.

This study documents, from the patients’ point of view, that educational gaps are significant.

Even in patients initially trained, education on correct injection techniques has a fleeting effect if not regularly recalled.

Therefore, for efficient preventative and rehabilitation purposes, it is urgent to educate both doctors and nurses repeatedly on the importance of correctly injecting insulin to improve patients’ knowledge and skills.
