What phenomenon describes the normal morning increase in blood sugar levels?

The phenomenon that describes the normal increase in blood sugar levels that occurs in the morning is known as the Dawn Phenomenon. This occurs due to a combination of factors, including increased hormone production during the night that affects insulin sensitivity. As the body prepares to wake up, hormones such as cortisol, glucagon, and epinephrine are released, which can raise blood glucose levels in the early morning hours.

Understanding the Dawn Phenomenon is crucial for managing diabetes, particularly in adjusting insulin or medication doses to account for these natural fluctuations. This is unlike other phenomena such as the Somogyi Effect, which involves a rebound of blood sugar following low levels during the night, and is often related to the administration of insulin. Recognizing the Dawn Phenomenon helps healthcare providers and patients make informed decisions about blood sugar management strategies, especially in the context of morning routines and meal planning.
