Why is my urine yellow in the morning?

When getting up in the morning, one thing many people have to do is to urinate, but the color of urine is often yellow. What does this have to do with our body? Generally speaking, the urine excreted from the body by a normal person is indeed a bit yellow. If you want to know the specific reasons why the urine is yellow, then read the introduction below.

The color of urine is also related to the temperature of the weather. It is clear when it is cold and yellow when it is hot. This is related to sweating and how much water you drink, but it can also change with diet. Or if you consume too much acidic food, your urine will be dark in color, and if you consume too much alkaline food, your urine will be light in color. Sometimes, taking a few riboflavin tablets orally can cause the urine to turn dark yellow. However, these changes in urine color are extremely short-lived and will recover on their own soon.

Normally, the waste produced by the human body and the urine pigments excreted every day are generally relatively constant, so the color of urine will not change much. 96%-99% of urine is water, and most of the rest is waste, such as uric acid, creatinine, etc. The normal daily urine volume of a person is 1000-2000 ml, among which men produce 1500-2000 ml per day. 1000-1500 ml for women. The urine is light yellow in color and transparent without any precipitation or turbidity. Freshly excreted urine has a special grassy aroma, but after being left for a long time, it develops an ammonia smell due to decomposition.

Hepatitis may also cause yellow urine, but yellow urine does not mean you have hepatitis. When you wake up in the morning with yellow urine, you should first consider whether you are not drinking enough water, sweating too much, or taking any medicine, etc. If your urine is yellow only once or twice and you don’t feel any discomfort, you don’t need to worry. If your urine is always yellow, and you feel tired, weak, and have loss of appetite, you need to go to the hospital for a check-up in time.

There are many reasons why your urine is a little yellow in the morning, which are related to our diet and weather changes. If there is no problem with your body, the yellow urine will not last too long, just a few days. However, if it lasts too long, you should be prepared to go to the hospital for examination in advance.
