What is the primary result of the Dawn Phenomenon in regards to blood sugar levels?

The Dawn Phenomenon refers to the natural increase in insulin resistance that occurs in the early morning hours, leading to elevated blood sugar levels when an individual wakes up. This physiological response is primarily due to the release of hormones, such as cortisol and glucagon, that increase glucose production by the liver.

As a result, individuals, particularly those with diabetes, may experience pre-breakfast hyperglycemia, meaning their blood sugar levels are higher than normal upon waking. This occurs despite no food intake during the night. The phenomenon often causes challenges in managing blood glucose levels, making it critical for people with diabetes to monitor their levels carefully and adjust their insulin or medication regimens accordingly.

The correct answer identifies the Dawn Phenomenon’s direct effect on blood sugar levels, highlighting the increase in glucose levels that occurs in the morning hours prior to eating breakfast.
