I have stage 3 CKD [ 40%] with hypertention which is being controlled by mediction and includes a water tablet. However I just had a blood test and my potassium is low, so the Dr. thinks it's the water tablet causing the problem and took me off them, the thing is without them I get edema in the feet and ankles, and my body feels bloated. I know there are some potassium sparing diuretics but my Dr. didn't suggest giving them to me. I'm also worried about my kidney's. I'm eating food with high potassium to get the levels up.
