Dawn phenomenon is a phrase that is used in relation to the elevation of blood sugar or glucose that occurs in the early morning hours in people affected by diabetes. This most often occurs in the very early hours of the morning, generally between 2 and 8 am.
It is believed by some that this is caused by the release of hormones that occurs naturally overnight. Some of these natural hormones include glucagon, epinephrine and cortisol and may increase the resistance to insulin. This is because these hormones are actually produced to work against the effects of insulin which causes the levels of insulin to rise.

Some of these causes may include taking the wrong amount of insulin the night before, consuming snacks containing carbohydrates close to bedtime or taking the wrong amount of other medications. It may become necessary to check your sugar levels during the early morning hours to determine if this is actually to the dawn phenomenon or if there may be another cause for this issue.

Some of these steps may include changing your insulin dosage or that of other medications, changing medications, using a pump to deliver additional insulin during the early hours of the morning and not consuming carbohydrates close to bedtime.

Your doctor may suggest you check your glucose levels around 2 or 3 in the morning to see if this is the issue.
