Dawn phenomenon is a normal early-morning rise in glucose (blood sugar) that occurs before or shortly after waking. Everybody experiences this physiological phenomenon,but it can be troublesome for people with diabetes. Such people may need to adjust their treatment regimen to account for dawn phenomenon.
Between 4 a.m. and 8 a.m., the body increases the production of certain hormones. These natural body chemicals suppress the activity of insulin, a hormone that transports glucose into cells to use for energy and reduces blood sugar levels.
These hormones trigger the liver to release enough glucose to give the body the energy to wake up. In non-diabetic people, the body responds to the excess glucose that accumulates as a result of this process by producing insulin. The insulin then moves the excess glucose into the cells. However, people with diabetes either fail to produce insulin or cannot properly use the insulin that is available. As a result, glucose continues to rise to abnormally high levels (hyperglycemia).
This interfere with treatment of patients with diabetes especially when it comes to dosing of the insulin
