Patient's question:
Polydipsia, polyphagia, significant weight loss, poor mental state, frequent insomnia recently, and some decline in vision. Over a year.Doctor's answer:
Hello! Diabetes is a metabolic disease characterized by a lack of insulin secretion or poor utilization, with fasting blood glucose levels greater than 7.0 mmol/L and postprandial blood glucose levels greater than 11.1 mmol/L after 2 hours. Its main feature is chronic hyperglycemia, with typical symptoms including polydipsia, polyphagia, polyuria, and weight loss.The diagnostic criteria for diabetes are:
(1) Fasting blood glucose (fasting for 8-12 hours) greater than 7.0 mmol/L
(2) 2-hour blood glucose during an Oral Glucose Tolerance Test (OGTT) greater than 11.1 mmol/L
(3) Random blood glucose greater than 11.1 mmol/L
Any one of the above three criteria, if confirmed on another day by any one of them, leads to a diagnosis. It is recommended to visit a diabetes specialty hospital for testing, including pre-meal and post-meal blood glucose, hemoglobin A1c, glucose tolerance test, pancreatic function tests, lipid profile, and microalbuminuria screening for diabetic complications.
Wishing you good health!
