What is the reason for yellow urine?

The main causes of yellow urine are too little drinking water, special diet and red blood cells in urine, as follows:

First, physiological reasons:

1, too little drinking water: when the weather is hot, sweating often turns the urine yellow, but under normal circumstances, if you drink too little, have insufficient rest or are tired, it can cause the urine color to deepen;

2, special diet: eating a lot of high-protein foods, as well as some special foods, will also make the urine color yellow and deepen;

Therefore, yellowing of urine is very common in normal life. If you drink less water and sweat more, the urine itself will be concentrated, so the urine will turn yellow. If you increase the amount of drinking water, that is, after drinking more water, the color of urine will gradually fade and return to a relatively normal range.

Second, the pathological reasons:

If the urine is abnormal, such as when there are red blood cells in the urine, the urine will turn yellow and dark brown or dark brown, because there are red blood cells in the urine. At this time, you should go to the hospital for examination, such as observing whether there are red blood cells in the urine and hematuria under the microscope. In addition, some patients will have intermittent gross hematuria in addition to the yellow urine color, and the urine will turn red like the color of the meat sample, so they should go to the hospital for further examination.
