A very yellow color of urine is most often a symptom of concentrated urine. If you have concentrated urine, you should drink more water, eat more vegetables and fruits, and eat a light diet to avoid fire. Because of fire, the color of urine will also be yellow. If you can’t get relief you have to go for a urine routine, because some liver and biliary diseases also have yellow urine, such as elevated urinary bilirubin or urinary bilirubinogen. Be sure to get an ultrasound of the liver, gallbladder and spleen to see if there is an obstruction or hemolytic liver disease, and if there is a disease such as cholecystitis. Again increased nitrate levels in the urine will also yellow the urine, and it is also necessary to drink more water to relieve. Generally drink more than 2000mL of water per day, the urine will no longer be concentrated and diluted, the urine will no longer be yellow and return to normal.
