Urine sugar (++++) is considered more serious, and normal people do not contain glucose in their urine. The most likely case of glucose in urine is elevated blood sugar. Due to high blood sugar, excessive sugar is eliminated from urine, causing elevated urine sugar, and it is important to check the value of blood sugar to determine whether it is caused by elevated blood sugar. In addition, due to kidney disease, the renal glucose threshold is lowered and the ability of the renal tubules to reabsorb glucose is reduced, which also causes sugar to be excreted from the urine, so you can further check the kidney ultrasound and other related tests to rule out kidney disease. In addition, the renal glucose threshold also decreases in women in the case of pregnancy, causing glucose to appear in the urine. No matter which condition causes glucose to appear in the urine, it is important to pay attention to it and actively check the cause. If the urine glucose is caused by elevated blood sugar, further diagnosis and treatment at the endocrinology department is essential.
