My doctor had me on Lasix and potassium for 3 years because of edema and the threat of pulmonary edema. I finally took myself off it nearly a year ago because I had lost nearly all of the swelling except that which appears towards the end of the day but is usually gone in the mornings when I wake up (probably from me being inclined for 6 to 8 hours ). My edema is probably the result of having bad airways to my lungs and simply not getting enough oxygen for my heart to pump properly, thus causing my kidneys to operate somewhat incorrectly. I think you ll know what I mean ? Am I okay to stay off the lasix and potassium ? Thanks, Thomy
