The possible causes of cloudy morning urine: 1. Chronic urinary tract infection. When the urine containing bacteria is discharged from the body, cloudy urine can be seen, and flocculent or filamentous precipitates can be seen in it, and patients may have discomfort such as frequent urination, urgent urination and painful urination. It is recommended that the cloudy urine be retained for routine urine examination and urine culture examination. If bacteria are visible in the culture and a large number of white cells are visible in the routine urine, it suggests bacteriuria, and further antibiotic anti-infection treatment is recommended. 2. Crystalluria. The organic fraction in the urine is cold and precipitates out, which can be manifested as crystalline material visible in the urine, which can be manifested as cloudy urine, generally without symptoms such as painful urination. When this type of urine is heated, the urine can change to a clear color, which often indicates crystalluria. In this case, it is recommended to drink more water and no oral medication is usually needed for treatment. Blood can be drawn to check trace elements and uric acid, etc. If there are metabolic problems, related medical treatment is needed, such as high uric acid, oral allopurinol tablets are recommended to lower uric acid and other treatments. 3. No water at night or too little water during the day, cloudy urine is visible in the morning, and yellowish urine is visible, mostly considered caused by excessive concentration. If the urine gradually turns to clear color after drinking a lot of water, the urine concentration is considered. However, if you drink a lot of water and still see cloudy urine every time you urinate, it is recommended to go to the hospital for further examination to clarify the specific diagnosis.
