Urine sugar is not necessarily diabetes

China's traditional Chinese medicine to

        Urine sugar check is the most simple diagnosis of diabetes is the most commonly used method, in many people's mind, as long as the urine sugar inspection result positive, it must be diabetes, urine sugar can reflect the level of blood sugar, both between should be consistent, won't be wrong.

        Indeed, every day from urine can be normal vent trace glucose, generally not more than 32 ~ 93 mg, urine sugar qualitative check for sex. If 24 hours urine sugar quantitative more than 150 mg, namely for glycosuria, the urine sugar qualitative check for more positive, glycosuria, hint diabetes. That is as blood glucose abnormalities is increased more than renal sugar threshold value, urine comes I glycosuria, urine sugar test was positive. Just as normal rule, when the blood sugar more than 160 to 180 mg/dl (8.9 ~ 10 mmol/L), urine did not appear in the urine sugar, urine sugar positive, we often think of the blood sugar level called renal sugar threshold value. Usually only when the blood sugar and sugar with increased more than kidney and value, urine have glycosuria, therefore, glycosuria often prompted the blood glucose abnormalities increases, generally speaking, the emergence of the urine sugar and severe degree and the rise of blood sugar is consistent, namely blood glucose abnormalities rise and urine sugar positive degree is consistent, if 24 hours urine sugar quantity more than 1 g, urine sugar qualitative obvious positive, can be highly suspected diabetes, should further check blood sugar in order to make clear diagnosis.

        But glycosuria are not necessarily diabetes. Because, the blood sugar in the kidney of the discharge depends on three factors: blood sugar concentration of glucose levels in the blood, kidney filtration capacity, kidney of glucose levels in the blood and absorption ability. Instead of the three factors in a state of equilibrium, the urine sugar free. If the three factors of any change, three out of balance, could cause a glycosuria. In addition to diabetes outside, there are many reasons can cause urine sugar test positive:

        1. Renal glycosuria: is mainly due to kidney sugar heavy absorption function is impaired, so that some of the sugar from urine leakage, cause urine sugar test is positive, but the normal level, see more at chronic nephritis, nephrotic syndrome, familial glycosuria and neonatal glycosuria, etc. A few pregnant women also have temporary kidney sugar lower threshold and appear glycosuria.

        2. Inside secretory glycosuria: with endocrine and metabolic disease person, urine sugar often higher. Such as thyroid, adrenal cortical, anterior pituitary and endocrine gland function hyperfunction, urine sugar was positive.

        3. Stress glycosuria: in cerebral hemorrhage, brain tumor, skull fracture, brain trauma, anesthesia, etc., these diseases sometimes blood sugar will be temporary, high with glycosuria, and as the disease relief, blood sugar, urine sugar into a negative return to normal.

        4. A glycosuria: if some people in a short time to eat too much sugar, honey or high sugar content of fruit, sugar soon after intestinal absorption into the blood, blood sugar concentration increases, more than the renal sugar threshold, it will cause diabetes. When to stop eating these foods, the urine sugar will turn quickly.

        5. Urine sugar false positives: some patients taking aminopyrine, caffeine, vitamin C, salicylic acid preparation or adrenal cortical hormone, and oral contraceptives, etc., often inhibit insulin release body, urine sugar can be a false positive reaction. (ChenYanLin)
