Unmasking the Dawn Phenomenon: Why Morning Blood Sugar Spikes?
Published: Apr 30, 2024
Ever wonder why blood sugar levels rise in the early morning? It's called the Dawn Phenomenon, and here's what you need to know.
What is the Dawn Phenomenon?
The Dawn Phenomenon is a term used to describe an early morning increase in blood sugar levels. This happens due to the body's natural release of hormones like growth hormone and cortisol, which can block insulin's effectiveness. These hormones are typically released between 2:00 AM and 8:00 AM, leading to higher blood sugar levels upon waking.
Why Does it Happen?
During the night, the body releases hormones to prepare for the day, which can increase blood sugar levels. This is a natural process that occurs in everyone, but for people with diabetes, it can lead to higher than normal blood sugar levels in the morning. Individuals with diabetes may need to adjust their insulin therapy to counteract this effect.
Managing the Dawn Phenomenon
To manage the Dawn Phenomenon, people with diabetes might need to adjust their insulin dosage or timing. Using an insulin pump can help by allowing for precise adjustments in insulin delivery during early morning hours. Regular blood sugar monitoring is also crucial to make necessary modifications to insulin therapy.
