Mer, I suppose it's possible. I know that I've always been encouraged to drink a lot of water, which is not my favorite thing. I'm now getting spring water and I carry a bottle of that around with me, everywhere I go. I also mix Crystal Light with it to make it more palatable. Since I'm on Lasix, I could get dehydrated easily, especially in the FL heat. Of course, sometimes when ascites and edema are bad, or there are kidney problems, a patient will be instructed to reduce fluid intake. It all depends on the individual. I've read that by a time a person (anyone, not necessarily a liver disease patient) realizes they are thirsty, they are already dehydrated.
Hugs,
Connie
