Why does drinking a certain amount of water turn into SO much more urine?
In: 375
Water in equals water out. You can’t pee out more water than you consume. In fact, you lose less water as urine than what you take in, since you also lose water through your sweat and through breathing, and a small amount in your poop.
In principle, though, you *can* pee out more than you *drink*, because drinking isn’t the only way you consume water. You also get water from your food. Fresh fruit and veg can be more than 90% water, and even a cooked piece of meat is more than 50%. If you have a glass of water and eat a cucumber, your total water intake is a lot more than one glass. And so, if you’re not sweating much, you may subsequently pee out more than a glass’ worth of urine.
However, the more likely explanation is that you’re simply mistaken, because this is very hard to track. Even if you’re keeping meticulous track of how much fluid you drink, you’re likely not keeping track of how much urine you pee out. You’re just eyeballing it and thinking “gee, that sure seems like a lot”. Also, the water you consume (in drink or food) takes time to be reflected in your urine output – sometimes more, sometimes less. If you drink a glass of water, and then shortly after you have a pee, you shouldn’t expect that that pee equals the glass of water. You might have had something to eat or drink earlier that’s also now showing up in there (not literally as the same water molecules, but in terms of the amount of urine that your body produces).
