Sips?
Take a teaspoon. Use it to drink. If you have no problem getting that amount down, then go up to a tablespoon. You'll be surprised how fast those teaspoons and tablespoons add up.
Getting enough fluid is your job right now. Even more important than protein. So keep working on it. Try differen****er temperatures and see what goes down easiest. And try to remember that this isn't forever; it's just for now!
I'm no scientist or medical professional but bear with me (was that the right "bear")? And if someone has better technical knowledge please correct me. But this is how it was explained to me...
Well hydration is pretty important and nothing to sneeze at especially after a high trauma event like a surgery when your body is super stressed out and you don't want it to lack for anything it needs when it's already so overwhelmed..Hydration effects blood consistency and volume which effects how quickly it gets around which in turn effects how quickly your organs get the oxygen and nutrients they need. Ever had blood drawn early in the morning and had it come out looking like syrup...yeah that's dehydrated blood and it's slow.
.but if you want WLS specific reasons...two words...fat metabolism. Ever wonder where the fat goes? I mean it's a substance that has volume and weight ( obvi) and it has a waste product. It goes somewhere- mostly into our urine. We also exhale it- but that's harder for our body to do so Urine. Also- our kidneys need plenty of water to do their jobs and when they are under resourced their work gets picked up by the liver- the liver that is responsible for...drum roll...metabolism.
But aside from all that- especially post op- you'll just feel better when you are hydrated- at least I did. All I wanted for two weeks was glass after glass of ice cold water.
