We investigated the relationships between the presence of abdominal induration caused by repeated same site insulin injections and the HbA1c and daily fasting blood glucose (FBG) levels, as well as improvements in these values following injection site education in type 2 diabetes patients. Data regarding the presence/absence of abdominal induration, diurnal FBG variation and the HbA1c levels over the past three months were surveyed in 67 type 2 diabetics. Injection site education was then provided to the patients exhibiting induration, and the diurnal FBG fluctuations were compared over three months after the education. The changes in the HbA1c levels before and after the intervention were also compared. In the comparison of the groups with (n=20) and without (n=47) induration, the daily FBG variations were significantly greater in the group with induration (p<0.01). Both the degree of FBG variation and HbA1c levels significantly improved among the patients with induration who received injection site education (p<0.01, p<0.05 respectively). In addition, the post-education HbA1c improvement in the induration group was also significant compared to the HbA1c changes observed in the group without induration (p<0.05).
