I get that we need so many oz of water per day but what I don't understand is why does it seem that the risk of dehydration is more after surgery?

I think it's probably because we actually consume alot more liquid in the average course of a day than we think we do. Just think about how often you get a pop, a coffee, something to drink with Breakfast, lunch, dinner, etc. And of course we have liquids in our meals as well. So plenty of fluids in the course of the average day.

Now, we have a tiny stomach, so during our meals, we are not drinking (no room!). We can't just quickly guzzle down a bottle of Water when we're thirsty. We're not drinking the endless cans of soda we were before our VSG, and probably not having as much coffee, tea, etc. either.

So we're getting dry.....alot more dry than we were when our stomachs were at our original size.

I could be wrong, but this is what makes sense to me........can some of the local "experts" chime in on this?
