In normal people, after urination, the situation of stickiness does not occur after the urine dries up, if it occurs then the possible causes: 1. Diabetic patients. When diabetic patients have poor blood sugar control, they can have a positive urine sugar expression. Because urine contains a large amount of sugar, this can occur after urination and after the urine is dry. If patients find that their urine is dry and sticky after urination, they should consider whether they have diabetes, and a routine urine test is recommended to find out whether urine sugar is elevated. If the single urine sugar is elevated, you need to check the fasting blood sugar level to rule out diabetes. 2, when the urinary tract infection, there may also be dry urine after the sticky situation. The reason is that after the infection, there is an increase in the formation of urine, and the urine contains a lot of flocculent material, including sticky bacteria, purulent cells, white blood cells and other conditions, and the urine becomes sticky. If there are also symptoms of frequent urination, urgency and painful urination, urinary tract infection should be highly suspected. It is recommended to retain urine and do urine routine and bacterial culture examination to rule out the presence of urinary tract infection.
