INTRODUCTION. The goal of the study was to assess the influence of metabolic control in diabetes 1 patients, assessed by means of the glicated haemoglobin value, on gastric myoelectric activity in a electrogastrographic examination.
MATERIAL AND METHODS. The study was performed on 106 patients with diabetes type 1. The electrogastrographic examination allowed us to determine the percentage share of frequencies in the ranges from 1.8 to 15 cycles/min. The percentage share of frequencies in the range of 2-4 cycles/min was the object of this study. For further study the results were divided into two classes for the preprandial and postprandial period, based on the calculated mean percentages frequencies share. The electrogastrographic parameters: Period Dominant Frequency, Period Dominant Power, Dominant Frequency Instability Coefficient, Dominant Power Instability Coefficient were assessed. The patients were divided in two groups accordingly to the value of glicated haemoglobin, with values £ 7.5%, and > 7.5%.
RESULTS. Confirmed the mutual relationships between the electrogastrographic record and recording frequency, and with the glicated haemoglobin value. Low glicated haemoglobin values, high percentages share of frequencies in the range of 2-4 cycles/min in postprandial period, caused that the electrogastrographic parameters behave similarly as in patients with normal/near normal electrogastrographic function, with low glicated haemoglobin value. In group with high glicated haemoglobin values and low percentages share of frequencies in the range of 2–4 cycles/ min in postprandial period, electrogastrographic parameters behave similarly as in patients with normal/ near normal electrogastrographic function and, with high glicated haemoglobin.
