Ok, let me preface this by saying I am not seeking a diagnosis, obviously no one can tell me conclusively, but I just want an opinion if this is something worth questioning.
My MIL is morbidly obese, has congestive heart failure, insulin dependent diabetic. She was in hospital a couple of weeks ago because she had fluid on her lungs. Among other things she was given diuretics that she is continuing to take, as per the drs instructions. Whilst in hospital she was told she could only have 1.5 litres a day of fluid and apparently is meant to continue this at home. My question is, does this sound like something that we should be questioning. She is a big woman, passing a lot of fluid, it is 30+ degrees here this week and only able to drink 1.5litres of all fluid each day. I am concerned that dehydration will be more detrimental to her.
