Question

A 47-year-old man recently experienced a decline in vision, feeling like he has presbyopia, and often feels hungry, has frequent urination, is unwilling to walk, experiences pain in his feet when standing, has long-term abdominal bloating, increases his appetite but reduces bowel movements, and often feels dizzy. He has undergone routine blood tests, hepatitis B series tests, and rapid blood glucose tests. His hemoglobin is slightly elevated, all hepatitis B tests are negative, and the rapid blood glucose test result is 4.6mmol/L. He ate a cookie after lunch. He inquires whether these symptoms are indicative of diabetes.

Answer

The typical symptoms of diabetes include polydipsia, polyphagia, polyuria, and weight loss. Due to individual differences, many early-stage patients may not have obvious symptoms. The diagnosis of diabetes mainly relies on blood glucose levels. If the fasting blood glucose is greater than or equal to 7.0mmol/L, or the 2-hour postprandial blood glucose is greater than or equal to 11.0mmol/L, or the 2-hour blood glucose during the oral glucose tolerance test is greater than or equal to 11.0mmol/L, diabetes can be diagnosed. It is recommended to undergo blood glucose tests, such as glycosylated hemoglobin and oral glucose tolerance test, for a definitive diagnosis and subsequent treatment.
