Dawn Phenomenon And The Somogyi Effect - Overview

The dawn phenomenon and the Somogyi effect cause high blood sugar levels, especially in the morning before breakfast, in people who have diabetes. The dawn phenomenon is a normal rise in blood sugar as a person's body prepares to wake up. In the early morning hours, hormones (growth hormone, cortisol, and catecholamines) cause the liver to release large amounts of sugar into the bloodstream. For most people, the body produces insulin to control the rise in blood sugar. If the body doesn't produce enough insulin, blood sugar levels can rise. This may cause high blood sugar in the morning (before eating). If the blood sugar level drops too low in the early morning hours, hormones (such as growth hormone, cortisol, and catecholamines) are released. These help reverse the low blood sugar level but may lead to blood sugar levels that are higher than normal in the morning. An example of the Somogyi effect is: A person who takes insulin doesn't eat a regular bedtime snack, and the person's blood sugar level drops during the night. The person's body responds to the low blood sugar by releasing hormones that raise the blood sugar level. This may cause a high blood sugar level in the early m Continue reading >>

    "response tp excessive dose of insulin. is a hypoglycemic condition that usually occurs in the predawn hrs of 2-4am. there is a rapid decrease in blood glucose which stimulates a release of hormones (eg cortisol, glucagon, epinephrine) to increase blood glucose by lipolysis, gluconeogenesis, & glycogenolysis. blood sugars must be monitored between 2-4 am & reduce the bedtime insulin level"
    this is straight from the pharm book

    Basically means rebound hyperglycemia. Your blood glucose level drops too low overnight, and to compensate the body over-reacts by releasing a whole bunch of chemicals which result in elevated blood sugar in the morning.
    Way to avoid the rebound is to avoid the hypo - may mean timing or dosing the night time insulin differently.
