Objective:
The aim of this study was to characterize the features of vegetative gastric neuropathy observed in diabetic patients based on surface electrogastrographic recordings.
Patients And Methods:
An electrogastrogram was recorded over an 8 hour 30 minute period in 63 patients with asymptomatic insulin-dependent diabetes and in 15 non-diabetic controls. Normal the electrical frequency of the stomach is 2 to 4 cycles per minute (cpm). Bradygastria is defined as a frequency below 2 cpm and tachygastria by a frequency above 4 cpm.
Results:
The diabetic patients showed a below normal gastric frequency and enhanced tachygastria over the entire recording period and during the pre, per and post-prandial periods. These vagal alterations were not correlated with the principle features of diabetes.
Conclusion:
Electrogastrography confirms that vegetative gastric neuropathy occurs early in patients with asymptomatic insulin-dependent diabetes. The tachygastria could lead to the increased rate of gastroparesis reported in these patients.
