What do 1 plus sign, No.2 plus sign and No.3 plus sign mean in urine sugar? My friends are two plus signs!

There is no glucose in urine of normal people. If the blood sugar is too high, the kidney will excrete too much glucose from the urine, and there will be glucose in the urine, which is urine sugar. Only when the blood sugar reaches a certain height can sugar leak out of urine, and the lowest concentration of glucose that the kidney can excrete from urine is called "renal sugar threshold".

According to this situation, you may have a temporary high urine sugar, which may be related to eating foods with high sugar content in recent days. Guidance: I suggest you don't worry, just observe. I wish you good health

Fasting blood glucose should be detected in the diagnosis of diabetes mellitus. The diagnostic criteria of diabetes mellitus are: normal fasting blood glucose range is 6. 1mmol/L, 2-hour postprandial blood glucose is less than 7.8mmol/L, when fasting blood glucose is ≥7.0mmol/L, 2-hour postprandial blood glucose is ≥1.1mmol.

Simply put, it is high blood sugar and too much urine protein. Suggest going to the hospital.

Extended data:

Primary renal glycosuria is the result of glucose reabsorption disorder in proximal renal tubules, also known as familial renal diabetes or benign glycosuria. Klemperer first described the primary nephrotic syndrome in 1896. Its characteristic is that when the blood sugar and the sugar concentration in the filtrate are normal, due to the obstacle of glucose reabsorption by renal tubules, too much glucose is excreted in urine, so it is called renal diabetes. Complications: dehydration, malnutrition, hypoglycemia and so on.
