Urine glucose 1+ is usually abnormal, and there are two main categories of physiologic and pathologic causes. Under normal circumstances, the renal tubules in the kidneys can reabsorb almost 100% of the glucose in the glomerular filtrate back into the blood, and glucose will not appear in the urine.
1. Physiological causes: including eating a lot of carbohydrates, strenuous exercise, after injecting a large amount of glucose, etc. In this case, there will be a transient increase in blood glucose, resulting in urine glucose 1+.
2. Pathological causes: it can be divided into urine glucose positivity caused by elevated blood glucose and urine glucose positivity caused by renal reabsorption disorders, the former is mostly seen in diabetic patients, and the latter can be seen in chronic nephritis, nephrotic syndrome, interstitial nephritis and other renal diseases.
When the patient appeared urine glucose 1 + need to go to the hospital in time, follow the doctor’s instructions to carry out relevant examinations to clarify the cause of the disease, according to the doctor’s advice for the next step in the treatment.
