Hi,
I've low potassium levels, it can drop to 3,2. Because of that I have potassium substitute 1,5g per day to keep a level of 4,2. Otherwise an atrial fibrillation may occure.
I'm not on diuretics, only on ACE inhibitor and on the betablocker bisoprolol. My kidneys are checked and all laboratory levels are very fine. I've no aldosteronism, this is checked too.
What could be causing the potassium loss?
Kind regards,
