Dawn phenomenon does not necessarily mean that diabetes is aggravated, but it needs to be taken seriously and certain measures should be taken. The dawn phenomenon of diabetes mainly refers to the fact that some diabetic patients have an abnormal increase in blood glucose between 3:00 a.m. and 9:00 a.m., but their blood glucose levels are well controlled at other times of the night, which may be due to the excessive secretion of free cortisol and growth hormone in the early morning. If diabetic patients experience the dawn phenomenon, certain treatment measures are required, such as strict dietary control, taking medication to lower blood glucose as prescribed by the doctor, and adding insulin. There are individual differences in the specific treatment plan, so it is recommended to consult a professional doctor and make adjustments to the lifestyle and medication plan according to your own situation.
