You Just Peed — So Why Do You Have to Go Again? Dr. Mandell

Have you ever gone to the bathroom, felt completely emptied out, and then an hour or two later wondered why you have to pee all over again—even though you haven't had anything else to drink? Where is all that urine coming from? In this video, Dr. Alan Mandell explains what happens to the water you drink after it enters your body, how fluid is absorbed through your digestive system and bloodstream, and how your kidneys continuously regulate water and produce urine. You'll discover why urination doesn't always happen immediately after drinking, how hormones such as ADH help control how much water your kidneys conserve or release, why drinking large amounts of fluid at once can increase urine production, and why drinking close to bedtime may contribute to those frustrating middle-of-the-night bathroom trips. You'll also learn how hydration timing, electrolytes, activity, medications, caffeine, alcohol, blood sugar, bladder health, and kidney function can influence how often you need to urinate. Frequent or excessive urination can sometimes have causes beyond simply drinking water, so persistent changes in urinary frequency, excessive thirst, pain, burning, blood in the urine, difficulty urinating, or repeatedly waking during the night should be discussed with a healthcare professional. Understanding how your body handles water can help you make smarter decisions about hydration throughout the day and better understand why sometimes, even though you just peed, your body tells you it's time to go again.
