title: [Glycemic patterns and excursions in well-controlled patients with type 2 diabetes mellitus].
abstract: To evaluate the glycemic excursions in well-controlled (HbA1c<7%) patients with type 2 diabetes mellitus.
  
  
  
  Thirty-two patients with type 2 diabetes whose HbA1c were<7% underwent CGMS (continuous glucose monitoring system).
  
  
  
  The highest blood glucose value was in 1.7 h after breakfast. The time duration for blood glucose levels of 7.8 mmol/L, 11.1 mmol/L and 13.9 mmol/L were 28%, 13% and 6%, respectively. The area above 7.8 mmol/L in blood glucose curve was significantly correlated with HbA1c levels. Asymptomatic hypoglycemia and continuous hyperglycemia (BS>13.9 mmol/L more than 2 hours) were also found in the study.
  
  
  
  The apparent hyperglycemia exists in well-controlled type 2 diabetic patients, and CGMS is useful in assessment of glycemia.
