Question

What is the cause of early morning hyperglycemia known as the Dawn phenomenon?

1) Increased insulin resistance
2) Decreased insulin production
3) Excessive nighttime release of growth hormone
4) Inadequate bedtime insulin dose

Answer 1

The cause of early morning hyperglycemia known as the Dawn phenomenon is excessive nighttime release of growth hormone.

Step-by-step explanation:

The cause of early morning hyperglycemia known as the Dawn phenomenon is excessive nighttime release of growth hormone. During the early morning hours, the body naturally releases growth hormone, which can cause an increase in blood glucose levels. This is because growth hormone stimulates the liver to produce more glucose. The rise in blood glucose levels is independent of insulin and can be seen in individuals with both type 1 and type 2 diabetes.
