why the heck do drinks that contain caffeine gotta make me pee so gosh darn much!? it really "pisses" me off! so why does drinking beverages with a high level of caffeine such as coffee, tea and soda turn your penis into a super soaker? you see, your pituitary gland located at the base of the brain is responsible for the release of a hormone called the antidiuretic hormone. or adh for short. adh is secreted into the blood stream where it will be taken to various places.
lighter roast coffee has more caffeine, one of which will be the kidney. during dehydration, adh will induce the production of aquaporins in the kidneys, specifically at the collecting ducts. aquaporins are proteins, or sometimes referred to as water channels that are embedded into the kidney to allow for water to pass through the walls of the collecting ducts. this is a nephron, the basic structural and functional unit of the kidney.
it has many different components to it, but we will only need to worry about the collecting ducts for this video. the collecting ducts is the final location where your body will decide to absorb more water or forever hold its peace as water issecreted out the tip of your bazooka, never to be seen again. more aquaporins means yourbody would be able to retain more water instead off peeing it out. which is a good thing sinceyour body is more than 60 percent water!
what the heck does all this talk about adh and water regulation have to do with drinks that contain caffeine!? well, caffeine is a party pooper that inhibits the release of adh! as a result, aquaporin production decreases and more water will enter your bladder instead of being reabsorbed. and that is why you gottato drain the main vein more often when you're drinking beverages with high levels of caffeine.
