Brief Answer:
FZluids overload need prompt management

Detailed Answer:
Thank you for asking

I read your question and i understand your concern. 6 litres is too much when a person needs maximum 3 litres and that too in 24 hours time frame. He will be managed for fluid overload and possibly hyponatremia at the hospital. Yes the condition is painful if fluid overload involves multiple organs, like lungs which will cause pulmonary edema and lead to shortness of breath etc. It may involve brain and cause brain swelling, cerebral edema and lead to seizures and respiratory arrest.

no worires with good hospital care, and prompt diuresis i am sure he will get out of this fluid overload just fine. Kidneys have the ability to excrete fluids at rate of 1 litre in an hour maximum. So with in a few hours he should be out of trouble. However work up to sort out this excessive thirst in first place should be done to avoid such mishaps in future.

I hope it helps. take good care of yourself and don't forget to close the discussion please.

Khan

I have had ISADH, for a long time. My nephrologist believes it s from head injuries I sustained over my lifetime. I met with a new nephrologist today, as my previous one left the group. I am confused and concerned, because I don t fully understand this disorder and am told to restrict my water intake to no more than 4, 8 ounce glasses of water a day. We also talked about using pedialyte, Gatorade, Co-Co Nut water, and Almond Milk, as part of this fluid intake. Do I still heavily salt my food? And worst cast scenario, she said I could get brain swelling. Please, if any of you docs can shed further information, and relieve some of my anxiety please do. Thank you. Virginia (Jenna) West
