Upper gastrointestinal symptoms particularly postprandial nausea, vomiting, early satiety, fullness and abdominal pain are common in diabetic patients. Autonomic neuropathy was thought to be the underlying factors and it may affect all parts of gastrointestinal tract. Aim of the present study is to study the effect of diabetes on the motility of gastrointestinal tract specially motility of esophagus, stomach and gallbladder, and to study the correlation between any abnormal findings on one hand and symptoms of gastrointestinal dysfunction, chronic complications of diabetes especially autonomic neuropathy, demographic data and metabolic control. The study included 30 diabetic children ( 19 males and 11 females ), their ages ranged between (9.3 – 19.7) years with duration of diabetes varied between 5-12 years. They are subjected to scintigraphy for esophagus, stomach and gallbladder and ultrasonography for gallbladder. Results revealed reduced gallbladder ejection fraction in 76 % of diabetic group by scintigraphy and in 35% by ultrasonography, decreased esophageal emptying in 43% and accelerated gastric emptying in 36% and delayed gastric emptying in 20% of diabetic patients. We can conclude from this study that gastrointestinal motility disorders in the form of impaired gallbladder contractility, decreased esophageal emptying and impaired gastric emptying are common in type 1 diabetes and occur more frequently in patients with autonomic neuropathy.
