What is dawn phenomenon?

Living with type 1 diabetes (T1D) may lead to experiencing a phenomenon known as the “dawn phenomenon” or the “dawn effect.”

During the early hours of the morning, typically between 2 a.m. and 8 a.m., your blood sugar levels may spike, resulting in higher readings even before consuming any food.

Several factors can contribute to this increase in blood sugar, such as the release of hormones early in the morning, which can heighten insulin resistance, insufficient insulin or medication remaining in your system from the previous night, consuming high-carbohydrate meals close to bedtime, or the liver releasing glucose into your bloodstream.

As individuals respond differently to various foods, you may wish to conduct additional testing to understand how specific bedtime snacks impact your blood sugar levels.
