Frequency of urination per day?


If a person does not drink water for an entire day, the normal frequency of urination is typically around 3 to 4 times.
However, if someone drinks approximately 1400 cc (about two bottles) of mineral water in a day, the normal frequency of urination would likely increase to about 6 to 8 times, depending on individual factors such as hydration status, kidney function, and overall health.

Hello: There are many factors that influence the frequency of urination, including fluid intake and sweating, among others.
Generally speaking, if the number of times you urinate during the day exceeds 7 times, it is defined as polyuria.
If you have further concerns, it is advisable to consult a urologist.

More Info


Understanding normal urination frequency is essential for assessing hydration status and kidney function. The frequency of urination can vary significantly based on several factors, including fluid intake, individual health conditions, and environmental factors such as temperature and humidity.

In general, the average adult typically urinates about 6 to 8 times a day when adequately hydrated. This frequency can be influenced by the amount of fluid consumed. For instance, if an individual consumes around 1400 cc (or approximately 1.4 liters) of water in a day, it is reasonable to expect a corresponding increase in urination frequency.
When an individual does not consume any fluids throughout the day, the body will conserve water, leading to fewer urination episodes. In such cases, it is not uncommon for a person to urinate only once or twice a day, depending on their overall hydration status and other factors such as diet and physical activity.
For someone who drinks about 1400 cc of water daily, the expected urination frequency could range from 6 to 8 times, assuming normal kidney function and no underlying health issues. However, this can vary based on individual factors such as:
1. Diet: Foods with high water content (like fruits and vegetables) can contribute to overall fluid intake and influence urination frequency.

2. Physical Activity: Increased physical activity can lead to sweating, which may reduce the amount of urine produced.

3. Medications: Some medications, especially diuretics, can increase urination frequency.

4. Health Conditions: Conditions such as diabetes or urinary tract infections can affect urination frequency and volume.

It is also important to note that the color of urine can be a good indicator of hydration status. Clear or light yellow urine typically indicates good hydration, while dark yellow or amber urine may suggest dehydration.

In summary, if you do not drink any fluids throughout the day, you might expect to urinate only once or twice. Conversely, if you consume around 1400 cc of water, you could expect to urinate approximately 6 to 8 times, assuming normal physiological conditions. If you notice significant changes in urination frequency or volume, it may be advisable to consult a healthcare professional to rule out any underlying issues.
