Follow-up: Sodium, potassium and magnesium when intake drops

On the subject in the title: Sodium, potassium and magnesium when intake drops Working notes rather than a conclusion.

A hydration and intake question, with the figures, since this one is unanswerable without them.

Fluid intake over a day, roughly, plus what I take with it and when. Intake is down substantially on where it was, which I gather is the ordinary consequence of eating much less rather than anything else.

What I would like to understand is which of the symptoms attributed to this are plausibly about fluid and salt, and which are being attributed there because it is the easy explanation.

Fluid intake and electrolyte intake are separate questions and drinking more water alone can make a dilutional problem worse.

The short version is the first sentence; the rest is why.

On post #4 — agreed on the reasoning, with one qualification.

Reduced intake reduces electrolyte intake alongside everything else, which is the mechanism behind most of what gets attributed to the compound here.

The uncertainty is in the assumption, not in the calculation.

Exercise and electrolyte losses: sweating during exercise increases sodium and potassium losses. Electrolyte replacement during or after intense exercise helps maintain balance.

It is a small point and it changes the answer, which is an awkward combination.

Following, with nothing to contribute beyond having asked the same thing elsewhere.
