Understanding The Causes Of Excessive Water Consumption

The tendency to consume excessive amounts of water, known as polydipsia, can stem from various underlying factors, both physiological and emotional. One potential cause is a medical condition, such as high blood sugar levels (hyperglycemia), which is often associated with diabetes. Experiencing an unquenchable thirst is a prevalent symptom in such cases. Additionally, heightened thirst may also arise as a response to fluid depletion during physical activity or after the consumption of salty foods. This phenomenon underscores the importance of understanding the diverse triggers that can lead to excessive water intake. This information was last updated on February 2, 2023.

The question of “How much water is too much in a day?” is crucial for maintaining proper hydration. According to Hultin, a registered dietitian, consuming an amount of water that exceeds the kidneys’ capacity for elimination could lead to a condition called hyponatremia in certain individuals. It’s important to note that the kidneys are capable of processing and excreting approximately 27 to 34 ounces (about 800 to 1000 milliliters) of water per hour, totaling between 676 to 947 ounces (approximately 20 to 28 liters) in a day. Going beyond this range may potentially put you at risk. This information is based on data available as of March 1, 2022.
