I noticed I had gained over 6 pounds since starting
CPAP. After just one night without the
CPAP I dropped 3 pounds, which I believe is all fluids.
My question is this: Could CPAP use cause your kidneys not to filter out fluids from your blood? When using CPAP I do not get up during the night to urinate. After one night without using CPAP I did get up to go to the bathroom, my weight dropped by 3 pounds and the pain is greatly reduced.
