The amount of urine may be related to physical health, so it is necessary for us to understand the amount of urine a normal person produces in a day. So how much urine does a normal person produce in a day? Next, this article will introduce to you the normal amount of urine a person should have per day, for your reference only. Friends who want to know more related knowledge can continue reading! Please see the detailed introduction below.

How much urine does a normal person produce in a day? 1500 ml per day. Our daily urine output should be around 1500 ml, but because people drink different amounts of water, there is no problem as long as the daily urine output is more than 400 ml and less than 3000 ml.

Experts remind that a daily urine volume of less than 400 ml is a manifestation of oliguria. The causes of oliguria are often shock of any reason, massive bleeding, severe dehydration, severe edema caused by large amounts of protein, urinary tract obstruction, heart failure, severe diarrhea, vomiting, high temperature or dehydration. If it is more than 3000 ml, it is considered polyuria, which can be due to renal or non-renal factors. Non-renal factors are common in patients with diabetes who have poor blood sugar control, those who consume too much water (psychological or compulsive), pituitary tumors, etc.; renal factors are more common in patients with nephrogenic diabetes insipidus, patients using diuretics, and chronic nephritis, chronic pyelonephritis, glomerulosclerosis and tubular diseases that cause renal tubular concentrating insufficiency.

Under normal circumstances, the amount of urine during the day is greater than the amount of urine at night (6 pm to 6 am the next morning). If the amount of urine at night exceeds half of the total urine volume for the whole day, it is called nocturia, which can be seen in chronic progressive kidney disease or tubulointerstitial disease.

Theoretically, a person should not urinate more than 8 times a day. 7 times during the day and 1 time at night is the best ratio. However, the amount of water consumed by each person is different, and it is normal to urinate 4-6 times during the day. However, it is best not to urinate at night more than twice. If you drink a lot of water before going to bed, the number of times you get up at night will increase, which is normal. But if you don’t drink much water at night and always get up at night, you should pay attention to illness.

Experts point out that healthy urine should be light yellow and transparent, without any precipitation or turbidity. But many factors can affect the color of urine, such as the amount of water you drink, changes in body temperature, and the effects of food and medication. When you drink a lot of water, your urine may be colorless like boiled water; when you drink less water and sweat a lot, your urine may be beer yellow. These are all normal.

The above is an introduction to how much urine a normal person should produce in a day. I believe that after reading the above introduction, you already know how much urine volume a normal person should have in a day. Generally speaking, a normal person's daily urine volume is 1500 ml. If it is less than 400 ml or more than 3000 ml, there is a problem and everyone should pay attention to it!
