High blood sugar in the morning is dangerous for diabetics
There are three main causes of high blood sugar in the morning. First, blood sugar levels in the morning change due to hormonal changes in the body called the dawn phenomenon.
Hormones such as cortisol and growth hormone often increase every day to stimulate the liver to produce glucose at dawn, causing blood glucose levels to rise slightly.
For people without diabetes will not experience side effects because the body produces enough insulin to regulate blood glucose.
However, diabetics who are unable to produce enough or poor insulin efficiency will not be able to regulate, causing blood sugar levels to rise.
Second, quantity. insulin may decrease in the morning due to the decrease in insulin at night.
When the dawn phenomenon occurs to coincide with the time when insulin decreases in the early morning, blood sugar will rise, because the person does not have enough insulin to regulate blood glucose.
Third, the Somogyi effect is a theory proposed by Dr. Michael Somogyi of the University of Washington in the 1930s. According to this theory, blood sugar levels rise in the morning in response to a bout of hypoglycemia at night.
Nighttime hypoglycemia can also occur if the person uses too much insulin or does not eat enough before going to bed.
