I keep having to take potassium because I keep losing it. What can cause this?

Diagnosis first: I would first have to ask why you know you are always losing potassium. The kidneys are very good at being able to hold onto potassium, especially when you aren't eating very much.

What causes a low blood calcium level?  Mine is 8.5 and i already take potassium and magnesium.  Do they have anything to do with it? Vit d 57.6
