what causes a sodium of 130 to drop to 105 in less than 3 days?

what causes a sodium of 130 to drop to 105 in less than 3 days?

I didn't take the first sample which came back at 110 so I assumed it was a mistake/from the drip arm so I repeated it from the other arm and it came back at 105. Pt has had some fluids but only a couple of L a day as they are NBM.

Pt also seems have haematemesis.

Was on diuretics but had been for long time.

It has the whole team quite bamboozled.

Haematemesis - is she a boozer or a secret boozer?

If she is has underlying cirrhosis - it is likely her negative feedback system that decreases ADH secretion in response to hyponatraemia is buggered (technical term ). That would contribute to it.

But hey if your team is stumped - it is probably something a bit bizarre.

Pretty sure she isn't a boozer. Very odd indeed

Why did she have haematemesis?

Good question - she is a stroke pt newly started on asprin so probably has an ulcer - she is for a scope tomorrow (if she makes it to tomorrow )

Magic beans in the hospital food for all I know

Can't salicylate toxicity do that? i.e haematemesis and hyponatraemia?

What's an Orthopods definition of hyponatraemia?
A reason to try and bounce the patient to the medics.

Or an excuse to write "NaCl sachets, TDS with food" on the Rx chart
