Whether we are awake or asleep, our kidneys never rest and work hard all the time. It is up to the kidneys to discharge metabolic waste and realize the balance of water and salt in the body.
Urine can be said to be the sweat of kidney work. Urine contains water, a handful of metabolic wastes from blood, uric acid, creatinine and other substances.
In fact, urine contains many small secrets, which is a barometer of kidney health.
In this article, I will solve some questions about urine for everyone. Let’s not mention routine urine tests or other high-level tests, but only start with the most direct urine volume, urine color and urine smell of the senses, and talk about some interesting news and their relationship with health.
How much does a healthy person urinate in a day?
The amount of urine in a person depends on the glomerulus and renal tubules (functional units of the kidney) in the kidney.
The normal adult urine volume ranges from 1,000 to 1,500 per day, which is about the amount of a large barrel of beverages. Usually, the urine volume during the day is more than that at night.
More than 2,500 milliliters of urine per day is polyuria, less than 400 milliliters is oliguria, and less than 100 milliliters is considered anuria. In case of these problems, be sure to go to the hospital in time to check if there is something wrong with the kidney or other organ systems.
In addition, urine volume is also related to climate, drinking water and food. Recently, the weather is hot and dry, sweating more, urine volume will decrease. Be sure to remember to supplement more water appropriately.
The amount of urine is also related to the size of the body. Big sumo wrestlers will definitely urinate more than babies.
If you look at the entire animal kingdom, the difference is even more interesting. Ten mice urinate only one tablespoon a day, a horse urinates in two barrels a day, and an adult elephant can fill the bathtub with urine in one day.
Different urine colors indicate what?
As early as the Middle Ages, charts recorded doctors’ intuitive feelings about urine color and health. Now, we have a more detailed understanding of this.
Healthy urine is light yellow, and different colors of urine have different reasons. Sometimes, it indicates that further examination is needed in the hospital.
The following picture reflects the possible causes of urine color correspondence. How about a comparison?
Some of the above abnormal colors are related to diet and are usually only transient. When there is any abnormality, you may as well think about whether you have eaten anything special from what on that day.
However, if the urine color continues to change, or if there are abnormalities such as blood color, soy sauce color, milky white and black, please see a doctor as soon as possible to find out the reason.
Can the smell of urine explain what?
The smell of urine sometimes changes. Apart from a few cases that have pathological implications (e.g. Diabetic urine has honey smell), it is more often related to the food eaten.
Under normal circumstances, the smell of urine is faint ammonia, which is definitely not good to smell, but it is not pungent.
After drinking strong coffee, the smell of urine may also be permeated with the smell of coffee. If you don’t believe it, you can carefully experience the difference between cafe toilets and ordinary toilets.
The most famous and interesting example is asparagus. After eating asparagus, not only green urine may appear, but the smell of urine will also become moldy egg smell-but not all people can smell it, because only 22% of the population have genes that can smell this smell.
After eating tuna, onions, saffron and other foods, urine will also be contaminated with their breath.
A little anecdote: ancient Roman ladies tried to take turpentine to fill their urine with the [noble] rose smell. This is obviously a foolish act that is not desirable because turpentine is toxic.
I hope this article can make readers intuitively feel the significance of urine to health.
