My potium level is 3.2, should I be worried?

This forum has its limitations. I do not have the benefit of a medical history, a physical examination, I do not know why your potium level was checked, and I do not know what your physician told you. A potium of 3.2 mmol/L if accurate needs to be corrected. If there is no obvious reason for a low potium level I most often repeat it to validate the finding. It is reproducibly low then potium replacement is appropriate along with further evaluation to try and identify the cause. If I may be of further istance please let me know. I wish you the very best of health and in all things may God bless.
