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
