Figure 5
HbA1c levels after BPD-DS dependent on preoperative duration of insuline usage. Group I “OAD” was treated by oral antidiabetic drugs only. HbA1c levels were below 6% as early as 3 months after the operation. Group II used insulin for less than 5 years preoperatively and also showed normal levels of HbA1c from 3 months after the operation on. Group III used insulin for 5 to 10 years. Mean HbA1c normalized 6 months after the operation. Group IV used insulin for more than 10 years. Mean HbA1c in this group normalized not until 2 years after the operation. Shown are mean values and additionally minimum/maximum values for preoperative and 2 years data.
