Low potassium: You low potassium (k) is concerning. You do not list that you are taking any diuretics that would lose both k and magnesium (m). Patients with m deficits have low k levels that cannot be corrected until their m is normal and your diet may not contain enough m to prevent a low level of it. Ask you physician to check your m and if it is low, its repletion will prevent further low k readings.
