My potassium in on low end of normal right now taking 20-40 meq of KDur, but they are referring me to endocrinologist and nephrologist. I have high Aldosterone and high Renin and they found Adrenal Adenomas, but normally with primary hyperaldosteronism you have low renin. With both elevated its either caused by diuretics, secondary hyperaldosteronism, or renin secreting tumors. I was briefly on diuretics per my doctor for the edema and super low urine output (200ml's/day only) and it caused my potassium to bottom out and again was hospitalized three times in last few months at 2.2, and twice 2.4. In order to get accurate Aldosterone and Renin levels, the nephrologist suggested 6 wks off before drawing and I waited 8 wks. I also have acute hypertension which is indicative of both primary hyperaldosteronism and renin secreting tumors or pheochromocytomas. They tend to cause low or normal low potassium levels. I just feel awful all the time and hope they can figure this out soon, but each dx is super rare and hard to dx.
