Water is the source of all things and the basic substance necessary for the activities of life. When the human body ingests water, after a series of absorption and metabolism of water, excess water will carry the waste produced in the body in the form of urine to excrete.
Under normal circumstances, the normal discharge of urine is a clear light yellow, and sometimes the water is drunk too much and the urine is diluted and is close to colorless. But many people occasionally find that their urine has turned yellow, brownish yellow, and some even turned black and red, which looks shocking.
Why does the color of urine change, and is it good or bad for the change in urine color? After reading the article, you may have a new understanding of urine.
First, what is the matter with the yellowing of urine, is it because there is less water?
Urine is the excrement formed by excess water and waste components in the human body, in the public mind, urine is useless, no one cares about its color, in fact, the color change of urine is also a health signal, and it has a great effect on the right.
The most common color change of urine is from light yellow to thick yellow, brownish yellow, this situation often occurs in morning urine, is the human body can not replenish water at night, but the metabolism increases the waste in the urine, so most people's morning urine will deepen in color and become thick yellow.
Similarly, sometimes the human body is dehydrated, the water is reduced, the concentration of waste matter increases, and the urine becomes a thick yellow color. However, morning urine and lack of water is only one of the most common causes of urine discoloration, and there are 3 major factors that can also lead to aggravation and thickening of urine color, many of which have the risk of disease, so be vigilant.
Dietary factors: carrots, kiwifruit, dragon fruit and other vegetables, melon and fruit foods, have natural pigment components, when the human body intakes too much in a short period of time, pigment has an impact on urine, which will lead to urine discoloration.
Drug factors: Rhubarb, dysenterythrox, and some drugs containing large amounts of riboflavin can also cause discoloration of the urine and recover on its own after stopping the drug.
Disease factors: when inflammation and fire occur in the human body, it may cause dehydration to deepen the color of the urine; Functional damage caused by hepatobiliary diseases, which increases urinary biliary or bilirubin in the urine and deepens the color of the urine; In addition, urinary disorders such as kidney disease, prostate disease, and urinary tract infections can also cause urine to turn yellow.
Second, the urine has these 7 color abnormalities, and we must also be vigilant
The color change of urine is far more than the deepening of this phenomenon, sometimes there will be other colors, we must be vigilant and check the root cause of the color change of urine in time.
Excluding the effects of diet, drugs and diseases, under the influence of water intake, human metabolism, sleep, etc., it is possible to urinate from light yellow to dark yellow, and it is necessary to analyze the specific situation.
