When she poured her son’s urine in the morning, she found that the potty was a white, cloudy urine that would form a precipitate at the bottom of the potty.

She took her son to the hospital to check his urine and found nothing abnormal. Analysis: There is no need for Zhang’s mother to be anxious. This white urine is actually caused by the crystallization of salts contained in the urine, which is a physiological phenomenon. There are phosphates and other salts in the urine, and as the temperature drops after discharge, the salts will precipitate out to form a precipitate, which will form white cloudy urine after the shock. Because children have a high metabolism and drink less water, this condition is most common in children in winter.

But a yellow urine color like strong tea is not caused by physiological reasons. Bilirubin is the main factor that makes urine yellow, and bilirubin can be excreted both through urine and through the intestines. When liver or biliary disease occurs, the bilirubin excreted from the intestines decreases, while the bilirubin excreted in the urine increases, and the color of the urine changes to dark yellow. Not only is this urine extremely yellow in color, it also tends to hang on the walls of the container when poured out from the container and is not easily poured clean, and often has foam after shaking. Bilirubin can also cause yellow staining of the skin and mucous membranes, called jaundice. In the early stages of hepatitis, when jaundice has not yet appeared, it is often observed that the urine is as thick as tea, so dark yellow urine is often an early sign of hepatitis. Other causes of yellow urine include eating large amounts of carrots and taking Chinese and Western medicines such as riboflavin, dysentery and rhubarb. Once you stop taking them, the yellow urine then disappears.
