Diabetic lipohypertrophy delays insulin absorption
RJ Young, WJ Hannan, BM Frier, JM Steel and LJ Duncan
The effect of lipohypertrophy at injection sites on insulin absorption has
been studied in 12 insulin-dependent diabetic patients. The clearance of
125I-insulin from sites with lipohypertrophy was significantly slower than
from complementary nonhypertrophied sites (% clearance in 3 h, 43.8 +/- 3.5
+/- SEM) control; 35.3 +/- 3.9 lipohypertrophy, P less than 0.05). The
degree of the effect was variable but sufficient in several patients to be
of clinical importance. Injection-site lipohypertrophy is another factor
that modifies the absorption of subcutaneously injected insulin.
