Question: Dear Doctor,
One year ago I was diagnosed with PVC-induced cardiomyopathy. I had an ablation surgery and my heart function and size returned to normal three weeks after ablation.

My first cardiologist told me that cardiomyopathy cannot be cured and I would die of fluid overload. My current cardiologist says I'm cured and have no need to worry however the first cardio's words keep going through my head and I am terrified while drinking, fearful I will retain the water and go into heart failure. I have seen a nephrologist and urologist who have told me my kidneys are in great shape.

My problem is that I feel I urinate less often than my co-workers and family members and I seem to have decreased bladder sensitivity- unless my bladder is very full, I don't strongly feel the urge to go unless I press on my abdomen to check. Also I am drinking a lot because if I drink less, I simply don't feel the need to urinate. I'm so frightened of not urinating that I measure and time every drop taken in and out.

I've attached a day's voiding diary. I have a watery diet as I'm vegan and eat a lot of fruit and vegetables. Also some lab reports with kidney function. My last kidney function tests were 4 months ago. Is there any need to repeat those tests now or would things likely be the same now?

I am so fluid obsessed it is making it impossible for me to live a normal
Life. Is the fluid retention I fear so much impossible?

Thank you,
XXXX

Hello,
No breathlessness now, no cough, and no edema of feet. When I had cardiomyopathy, I had a cough, orthopnea, and some mild edema in lower legs. That all resolved right after my ablation.

Thank you.

Thank you so much doctor,
I have a few questions which have been concerning me.
Is it normal to urinate less at night, close to bedtime, maybe because of anti-diuretic hormone kicking in for sleep? This has long worried me.

Are magnesium supplements bad for the kidneys even when kidney function is normal? I take a 600 magnesium supplement.

And lastly- is more fluid retained when active? I don't mean during exercise when there is sweating, but just walking around and doing everyday things. It seems I need to urinate more when I am sitting quietly at my desk ans less so when walking around. I do understand water is lost insensibly through respiration but does even very easy activity like walking use more water?

Thank you so much dr. I am trying very hard to live normally but got very close to death exactly a year ago so I'm having some trouble adjusting to the idea that I am now cured and healthy.

Thank you very muchz

Thank you so much, doctor.
I know my lab tests and overall urine volume are fine but I am worried about what seems to be decreased bladder sensation. It seems like I never feel great urgency, and have to push down on my abdomen a bit to feel if I have to go. For many months I was so anxious, I was pressing on my bladder all the time because I was so afraid I was retaining water. The ur
