Why is urine always yellow?

The urine color of ordinary people is light yellow. How clear it is when it is cold and how yellow it is when it is hot is related to sweating and drinking water, but it can also change with diet. If you eat an acidic diet, the urine color will darken; If you eat an alkaline diet, your urine will be light in color. Sometimes after taking a few tablets of riboflavin orally, the urine color will be dark yellow. Changes in urine color like this are extremely short-lived and will soon recover on their own.

Yellow brown urine should be distinguished from bilirubin urine or urine bile urine. Bilirubin urine disease is often caused by inflammation inside and outside the liver, tumors and stones blocking the biliary tract, which leads to the increase of bile duct pressure, bile duct rupture and bile overflow, leading to sodium bilirubin entering the systemic circulation. When sodium bilirubin exceeds a certain amount, bilirubin urine will appear. Urinary cholangitis is often caused by liver injury, which leads to an increase in urinary cholangitis absorbed by the intestine. When urine enters, urinary cholangitis will occur. Or patients with hemolytic anemia, because a large number of red blood cells are destroyed, a large number of urinary bile components are absorbed through the intestinal wall and enter the portal vein circulation. Because the liver can't convert excessive urinary bile elements into bilirubin, urinary bile elements also occur.

But that doesn't mean the urine is yellow or you have hepatitis. First of all, consider whether you don't drink enough water, sweat too much, take medicine, etc. If you only pee yellow once or twice and there is nothing wrong with yourself, don't worry. If the urine color is yellow all the time, and you feel tired and weak, loss of appetite, etc. Need to go to the hospital for examination in time.
