What is the normal amount of urine in one time

Normally the amount of urine is relatively regular. Of course, an increase or decrease in urine is not necessarily a disease problem. For example, drinking too much water or too little water can also cause changes in urine. However, if the amount of urine decreases frequently, you must be alert, as it may be related to decreased kidney function. So what is the normal amount of urine at one time? Let's take a look.

What is the normal amount of urine per time?

Medical research results show that the normal daily urine output of a normal person is 1000 to 2000 ml, with an average of about 1500 ml. Because a normal person

Every day, 35 to 50 grams of metabolic products and salt substances need to be excreted from the body in the form of urine through the kidneys. The minimum amount of water required to dissolve these solid substances is about 500 ml, so each person must excrete at least 500 ml of urine every day.

Therefore, according to medical regulations, when a person's urine volume exceeds 2500 ml throughout the day (24 hours), it is considered polyuria; if the urine volume throughout the day is less than 500 ml, it is considered oliguria; even more, if the urine volume is less than 100 ml, it is considered anuria.

If a person urinates too much, it will cause the loss of substances such as water and electrolytes in the body, which may lead to dehydration and electrolyte imbalance. Contrary

Yes, if the amount of urine is too little, the toxins in the body cannot be excreted in time, or cannot be excreted at all, the body's metabolism will still be disordered, and in severe cases it may be life-threatening. Therefore, it is very important to maintain normal urine volume.

The frequency of urination is: Under normal circumstances, a normal person should urinate 3 to 5 times during the day and 0 to 2 times at night, with each urine volume of 200 to 400 ml.

How to tell your health from your first pee

1. Green urine

Green urine will be discharged when taking large amounts of anti-inflammatory drugs or when Pseudomonas aeruginosa grows in the urine.

2. Brown urine

It may be bilirubinuria or urobilinuria. Bilirubinuria is often caused by intrahepatic or extrahepatic bile duct inflammation, tumors or stone blockage, which causes sodium bilirubin to enter the blood. When the amount of sodium bilirubin in the blood exceeds a certain amount, bilirubinuria occurs. Urobilinogenuria is often caused by liver damage, which leads to increased intestinal absorption of urobilinogen, which enters the urine, resulting in urobilinogenuria. Sometimes, in patients with hemolytic anemia, after a large number of red blood cells are destroyed, a large amount of urobilinogen is absorbed through the intestinal wall into the portal vein circulation. Because the liver cannot convert the excess urobilinogen into bilirubin, urobilinuria occurs.

3. Brown urine

Patients with severe burns, hemolytic anemia, wrong blood transfusion, acute nephritis, acute icteric hepatitis, or kidney compression may excrete urine that is the color of soy sauce. Some people excrete brown urine and experience dizziness, nausea, or yellow eyes after eating broad beans. They are medically called favism patients.

4. Milky urine

The most common is chyluria caused by filariasis, which is significantly aggravated especially after drinking milk or a high-fat diet. However, if milky urine is accompanied by abnormal urination, fever, and lower back pain, it should be suspected that it is a serious urinary tract infection, such as pyelonephritis, cystitis, urethritis or renal tuberculosis, which makes the urine milky white.
