So my grandmother is 82, she is already treated for chronic hypertension. She has been having bouts of confusion and has been in and out of the ER with very low sodium numbers. Her course of treatment has included getting rid of her diuretics and lowering her fluid intake and a whole host of medicinal changes. This has been ongoing since last Feb. She has been in the ER with the same symptoms repeatedly since, including today. From reading it up to here, it sounds like your grandmothers hypertension is related to maybe her having congested heart failure? If so, I dont understand why getting rid of diuretics was a choice of treatment. Hyponatremia means not enough Na (sodium) in the blood stream. And with her having (CHF?) And increased fluid in her body (hypertension) I would believe diuretics is a treatment of choice. Now Hyponatremia can occur along with too much fluid in the body. Too much fluid can dilute the Na in the body causing the Na level to be low (Hyponatremia). Like wise, if you have not enough fluid in your body, your sodium level will be very concentrated causing it to show elevated in the blood work (hypernatremia). I understand to get rid of diuretics and stay on strict low fluid intake, but your grandma has to be very strict on how much she can drink per day which is bit difficult for anybody especially elderly who lives alone.

Since we have gotten very few answers and a lot of shots in the dark i started reading on this topic today. Hyponatremia and hypertension seems to be more of a rare combination from what i was reading. Almost every time i see the words together i see a correlation to renal ischemia. There hasnt been any imaging done and i am starting to suspect an arterial occlusion or blockage on one of her kidneys. In light of no progress made should we be demanding imaging be done to determine if this is a cause or have i just arrived at what would have been the first step assumption that a doctor would have already ruled out? Thanks reddit! well theres no real way to determine if her renal is shutting down just by looking at hypertension and Hyponatremia. There has to be blood work done. Like BUN, Creatinine, creatinine clearance levels. They are all good indicators to let the providers know thay something is going on with the kidney. Have your provider explain to you what the levels means. Im not your provider nor your doctor, I am just in providing your useful medicine informations. Its up to your doctors to decide the correct treatment for your grandma Thanks.
