Low potassium from poor diet, now eating better, doing 24 hr urine test to check. nephrologist thinks it's all diet related. fixable with good diet?

Low potassium: If you have a poor diet, you may have a low serum magnesium (m) level. If your m is low, you will have a low serum potassium (k), which will not be normal until you increase your m with diet. Ask your neprhologist (n) what your m is. If it is low, and you replete it, you should no longer have low k level in your blood. Good luck.

Low potassium: Yes, indeed; if low potassium is truly from poor diet, then a potassium rich diet will fix the problem. A 24 hour urine test for potassium and magnesium and sodium is proper testing. Ask about aldosterone level, too.
