Is Your Daily Water Intake Normal? Hydration Needs - Family Medicine

Regarding daily water intake?


Symptoms: I have read some reports stating that one should drink at least 1500 to 2000 cc of water per day.
However, I drink less than 1500 cc daily.
Whenever I drink more than 1000 cc, I have to go to the bathroom every 40 to 50 minutes, and the urine output is quite high, with the color ranging from light yellow to colorless.
Is this normal for me? Is it necessary to drink 1500 to 2000 cc? It’s quite bothersome to keep running to the bathroom after drinking.
Duration: This has been the case for a long time.

Hello MIMI: Water constitutes about 70% to 80% of body weight and provides various essential components to cells while also helping to metabolize waste products from the cells.
In general, aside from obtaining moisture from food, an individual should drink 6 to 8 cups of water and beverages daily (approximately 900 to 1,500 cc).
The appropriate amount of water intake is closely related to each person's kidney function.
Generally, the daily water intake should be the total urine output from the previous day plus 500 to 800 cc for optimal hydration.
Gout patients have specific needs and should aim to drink seven large cups daily, with each cup being about 300 cc (approximately 1,500 to 2,500 cc) to increase urine output and eliminate toxins.
However, one should not consume too much water at once; drinking 3,000 cc of water in a single sitting can lead to water intoxication, which can be life-threatening.
It is best to drink water four times a day, with 1 to 2 cups (about 150 cc per cup) at a time.
The recommended schedule is as follows: (1) upon waking up in the morning (before getting out of bed), 1 to 2 cups (1 cup = 150 cc); (2) between 9:00 and 10:00 AM (1 to 2 cups); (3) between 3:00 and 4:00 PM (2 cups); (4) before bedtime (0.5 to 1 cup).
If water intake is excessive, it may lead to frequent urination, so it is advisable to reduce intake in the evening.
Sincerely, Dr.

More Info


When it comes to daily water intake, understanding your body's hydration needs is crucial for maintaining overall health. The general recommendation for adults is to drink between 1500 to 2000 cc (or milliliters) of water per day, which translates to about 6 to 8 cups. However, individual hydration needs can vary significantly based on factors such as body weight, activity level, climate, and overall health.

From your description, it seems you are experiencing some challenges with your water intake. You mentioned that you struggle to consume more than 1500 cc of water daily and that drinking over 1000 cc at once leads to frequent urination every 40 to 50 minutes. This can indeed be bothersome and may indicate that your body is reacting to the volume of water consumed at once or possibly your hydration status.

The color of your urine, which ranges from pale yellow to clear, generally indicates good hydration. Clear urine typically suggests that you are well-hydrated, while darker urine can be a sign of dehydration. However, the frequency of urination you are experiencing after drinking larger amounts of water could be a normal physiological response, especially if your kidneys are functioning well. The kidneys regulate fluid balance and can excrete excess water, leading to increased urination.

It's important to note that the recommended water intake is not a one-size-fits-all guideline. Factors such as your activity level, the climate you live in, and your diet can all influence how much water you need. For example, if you consume a lot of salty or sugary foods, your body may require more water to help process these substances. Additionally, if you are physically active or live in a hot climate, your water needs may increase.

If you find that drinking water in large quantities leads to discomfort or frequent trips to the bathroom, consider spreading your water intake throughout the day rather than consuming large amounts at once. This approach can help your body manage hydration more effectively and may reduce the urgency to urinate. A good strategy is to drink small amounts of water consistently, such as a cup every hour, rather than trying to meet your daily goal in fewer, larger servings.

If you continue to experience discomfort or if your symptoms worsen, it may be wise to consult a healthcare professional. They can assess your overall health, review your dietary habits, and possibly conduct tests to rule out any underlying conditions that could be affecting your hydration status or urinary frequency.

In summary, while the general guideline suggests a daily intake of 1500 to 2000 cc of water, individual needs can vary. Your current intake and the frequency of urination you experience may be normal for your body, but adjusting how you consume water could lead to a more comfortable experience. Always listen to your body and seek medical advice if you have concerns about your hydration or urinary habits.
