Abstract

We examined the relation between chronic glycaemic control (using glycosylated haemoglobin), haemodynamic autonomic function and rate of gastric emptying in 16 patients with type 1 diabetes mellitus. Gastric emptying was measured using a paracetamol absorption technique. Parameters of gastric emptying include area under the plasma paracetamol concentration time curve. Patients were classified as diabetic autonomic neuropathy positive or negative using five standardized haemodynamic reflex tests. Area under the plasma paracetamol concentration time curve in the neuropathy positive (10.36 (4.5) mmol−1 min) and negative (9.84 (3.0) mmol−1 min) groups were similar (P=0.42) using unpaired Student's t-tests. Glycosylated haemoglobin concentration and area under the plasma paracetamol concentration time curve (n=16) demonstrated a Pearson's correlation co-efficient of 0.24. Neither tests of haemodynamic autonomic function, nor concentration of glycosylated haemoglobin, are predictive of diabetic gastroparesis.
