My husband has been lung cancer free for 5 years....went in for a cholesteral check today....sodium is low and glucose is low....prior to this at a check up, his blood pressure was high...put on a diuretic med...his sodium level, after this, dropped. Put on lispronel at 10 mg....levels in sodium went up slightly, blood pressure still high on the top number...increased his blood pressure meds to 20mg.....they want to check at next app't. Should I be concerned with the low sodium and glucose, coinciding with each other.....
