Blood sugar and poor sleep may be related. Poor sleep tends to increase sympathetic excitability, induce oxidative stress, activate inflammatory pathways, cause alterations in the hypothalamic-pituitary-adrenal axis, and is a risk factor for impaired pancreatic β-cell function, insulin resistance, impaired glucose tolerance, and type 2 diabetes. It can be seen that poor sleep is likely to cause elevated blood glucose. In daily life, you need to pay attention to rest, do not stay up late for a long time, and patients with poor sleep can consult a doctor in time to improve their sleep condition and quality of sleep under the guidance of a professional doctor. Diabetic patients who do not sleep well are recommended to be treated under the guidance of an endocrinologist.
