dawn phenomenon

dawn phe·nom·e·non

abrupt increases in fasting levels of plasma glucose concentrations between 5 and 9 AM, in the absence of antecedent hypoglycemia; occurs in diabetic patients receiving insulin therapy.

Early morning hyperglycemia not preceded by hypoglycemia, linked to increased insulin requirements in type 1 DM, possibly due to nocturnal pulses of hGH; DP also occurs in insulin-pump users receiving continuous subcutaneous insulin infusion who are presumed to be euglycemic. The phenomenon is attributed to residual endogenous insulin or insulin-like molecules

Diabetology Early morning hyperglycemia not preceded by hypoglycemia, linked to ↑ insulin requirements in type 1 DM, possibly due to nocturnal pulses of hGH; DP also occurs in insulin-pump users receiving continuous subcutaneous insulin infusion, who are presumed to be euglycemic; DP is attributed to residual endogenous insulin or insulin-like molecules. Cf Somogyi phenomenon, Subcutaneous insulin resistance syndrome.

dawn phe·nom·e·non

(dawn fĕ-nom'ĕ-non) Abrupt increases in fasting levels of plasma glucose concentrations between 5-9 am in the absence of antecedent hypoglycemia; occurs in diabetic patients receiving insulin therapy.

dawn phenomenon

A sharp rise in the blood sugar level in the early morning in insulin-dependent diabetics. The rise is thought to be caused by nocturnal growth hormone secretion.
