Hyponatremia: There are several possibilities too numerous for a short answer. The most probable list includes drugs, SIADH, tumor (brain/lung) or a primary kidney problem. You need a good internist work up.

Polyuria: You are 93 and you are not on any medications? Thats incredible. If you have medical diagnosis and are on medications , then you need to provide us with that information. If you were otherwise without any other medical conditions or medications then I suspect diabetes insipidus causing polyuria leading to hyponatremia. This is easy to diagnose and treat. Please see your doctor.

Polyuria & low Na: Low serum sodium is unnatural and harmful, potentially. I assume you mean low serum sodium concentration. The right response IS polyuria - the renal excretion of the excess water - to raise serum sodium concentration. High blood glucose can lower serum sodium AND cause polyuria. So can potassium depletion. Some meds lower serum sodium. Diabetes insipidus causes polyuria but raises serum sodium.
