  • Dawn phenomenon

    Early morning hyperglycemia thought to result from decreased sensitivity to insulin. A marked increase in insulin requirements between 6 A.M. and 9 A.M. as compared with the midnight to 6 A.M. period. The increased dose of insulin required during this period is in contrast to the Somogyi phenomenon, which is managed by decreasing insulin during…
