AF symptoms yet urine test show HYPER...how?!

Hi all..

I've done an adrenal function urine test (measuring sodium chloride in the urine) twice now and both times i'm at the very upper level of HYPER. Less than 0.29% SoCl.

I really don't get it - i feel completely, in every way exhausted, and have a plethora of classic fatigue symptoms - except i'm not putting on weight.
Sweating like crazy, dizzy, foggy head, inability to cope with anything or anyone. Stimulation of life makes me feel 'hyper'...anxious, panicked, on edge etc. I could sleep forever.

What else could cause such a urine reading? I know aldosterone keeps sodium chloride in check, so maybe levels of Aldosterone are super high? What causes that?

Frequent urination day and night is another symptom.

Anyone help me understand this reading? I'm new to learning about AF.

Thanks in advance for any suggestions.
