The first female urine in the morning is yellow. What's going on?

When a woman urinates for the first time after getting up in the morning, the urine color is relatively yellow, which is mostly caused by concentrated urine, but it cannot be ruled out that there is jaundice or metabolic disease. It is recommended to go to the hospital for further examination to clarify the cause. 1. If urine concentration occurs at night, urine color is yellow in the morning, urine color can be restored to normal color after drinking more water or urine color can be restored to normal color at noon or afternoon, this situation does not need to be treated in hospital, only need to supplement water properly. 2. If urine color is yellow all day, it is recommended to further conduct urine routine examination and bilirubin index examination to rule out jaundice disease. If bilirubin and urobilin levels in urine are elevated, liver function and biliary tract system need to be further examined to rule out diseases such as hepatocellular jaundice or obstructive jaundice, resulting in excessive bilirubin and urine staining.
