If the urine appears cloudy in the morning, then the possible causes: 1. The phenomenon of concentrated and cloudy urine in the morning is manifested by the appearance of cloudy single urine, followed by urination belonging to the normal clear color. At the same time there are no symptoms such as frequent urination, urinary urgency and painful urination. It may be related to the phenomenon that urine stays in the bladder for too long and concentrated urine.2. After infection occurs in the urinary tract, urine containing bacteria can appear cloudy, and even urine containing pus can also appear cloudy. White flocculent material is visible after urine precipitation, accompanied by a history of frequent urination, urinary urgency, painful urination, burning in the urethra and pain in the small abdomen. A routine urine examination can be performed to rule out infectious diseases.3. Stones in the urinary tract and bladder can also cause cloudy urination. Because the urine contains stone particles, a transient cloudy urination can be seen during the urination process, and after the stones are completely discharged, the urine can return to its normal color.
