Is urine glucose 3 plus serious?

If the blood sugar is above 10mmol/L, the urine sugar will show positive. The urine sugar increase is not used as a standard for the diagnosis of diabetes. If the patient has three plus urine sugar, it is recommended to go to the hospital to check the venous blood sugar to see if he has diabetes. If the blood sugar is not high after the examination, it means that the renal sugar threshold is lowered, not diabetes, and at this time it is necessary to go to the nephrology department for diagnosis and treatment. If the blood sugar is increased after the examination, it is diagnosed as diabetes, and it is necessary to go to the endocrinology department for medical treatment. The blood sugar is controlled by drugs.
