Hi I’m new here...I have Atypical anti-GBM disease I have been on 80mg of Prednisone for the last 4 months . I too have the extremely big & hard belly it is so uncontrollable I feel like I haveing quintuplets every day. The constant pressure is horrible breathing is a chore. I also have the moon face & with this disease & the prednisone the water retention is also a battle ...My Doctor just this week has put my dose down to 60mg i have not noticed any changes yet but to be fair only been a week I don’t care about the moon face but this belly needs to go ....Any suggestion on how to get water retention down . I’m on a limited fluid intake 1.5 litres a day & I do take 2 different water pills everyday to get the water off ....not working so good if I’m on my feet for more a couple hours my legs & feet start look like California Red Woods .....any suggestions would be greatly appreciated.
