Possible causes of yellow urine in women: 1. If there is an infection of the urinary system there will be yellow urine and cloudy urine, accompanied by frequent urination, urinary urgency and painful urination. The urinary routine examination shows more white blood cells, or the number of bacteria significantly exceeds the normal level, anti-infection treatment is needed to restore the urine color to normal conditions. 2, if the diet or taking vitamin B drugs can lead to yellow urine, stop the relevant food or drugs after the urine color can be restored to normal. This is not a disease condition, just stop the food or medication and drink more water.3. If there are diseases of the liver or biliary system, such as viral hepatitis, alcoholic hepatitis or the presence of biliary stones or biliary tumors, yellow urine color can occur. Because the serum bilirubin level is elevated, which is the level of conjugated bilirubin excreted through the urine is elevated, the phenomenon of yellow urine will appear.
