[Continuous glucose monitoring in type 2 diabetes with gastroparesis].

Objective: To observe the glucose profile in type 2 diabetic gastroparesis.

Methods: 31 patients diagnosed with type 2 diabetes were enrolled into this study for measurement of gastric emptying of solids and continuous glucose monitoring to observe blood glucose levels for 72 hours on a balanced diet; the results were compared with 7 subjects with normal glucose regulation.

Results: 58.1% of 31 type 2 diabetic patients were found to have delayed gastric emptying of solids. The average glucose level was lower after breakfast [(7.82 +/- 1.42) mmol/L vs (9.35 +/- 2.28) mmol/L, P < 0.01] in the patients with gastroparesis than in those without. Maximal blood glucose level after breakfast [(10.21 +/- 2.17) mmol/L vs (12.24 +/- 2.82) mmol/L, P < 0.01] was lower in the patients with gastroparesis but it reached the peak at a similar time. Two hour AUC was also lower after breakfast in the patients with gastroparesis [(877.62 +/- 272.78) min x mmol x L(-1) vs (1028.40 +/- 283.98) min x mmol x L(-1), P < 0.05].

Conclusion: Post-prandial glucose level in type 2 diabetic patients with gastroparesis tends to be lower than those without.
