How much urine does a normal person produce per day?

A normal person has a certain amount of urine every day. Some people have frequent urination after drinking water, which is also normal. But some people have frequent urination without drinking water, which is abnormal. Some friends do not urinate even if they drink a lot of water. Many friends have no concept of how much urine is normal every day. How much urine does a normal person have every day? Let’s take a look at it next.

1. How much urine does a normal person produce per day?

Regarding urine volume, the average daily urine volume for a normal adult is 1500 ml, and the average is between 1000-2000 ml. If the daily urine volume often exceeds 2500 ml, it is a manifestation of polyuria. If the daily urine volume is often less than 400 ml, it is oliguria. If it is less than 100 ml per day, it is anuria. The above is normal urine volume. Polyuria or oliguria are both abnormal. The amount of urine volume is related to the lack of water intake and water loss through other channels. It is normal to maintain a daily urine volume between 1000-2000 ml.

2. Urine

Urine, commonly known as "urine" or "pee". It is metabolic waste and toxins excreted from organisms. It is a liquid that is generally yellow or colorless. Human urine is formed when blood flows through the glomerulus. Substances such as uric acid, urea, water, inorganic salts and glucose in the blood are filtered into the renal capsule through the filtration action of the glomerulus to form primary urine.

3. Formation

When the primary urine flows through the renal tubules, all the glucose, most of the water and some inorganic salts in the primary urine that are useful to the human body are reabsorbed by the renal tubules and return to the blood in the capillaries around the renal tubules. After the primary urine is reabsorbed by the renal tubules, the remaining water, inorganic salts, urea, uric acid, etc. form urine.

The urine formed in the renal tubules reaches the renal medulla through the renal papilla, and the renal medulla connects to the ureter to the bladder and is finally excreted from the body through the urethra.
