[gotcha] Advising plain water consumption to rehydrate after severe diarrhea or vomiting

Recommend Oral Rehydration Salts \(ORS\) specifically; advise against plain water alone, which lacks electrolytes and can cause fatal hyponatremia.

Journey Context:
Agents logically associate fluid loss with water replacement. However, severe GI fluid loss depletes sodium and potassium. Ingesting pure water dilutes remaining serum sodium, causing cerebral edema. WHO specifically formulates ORS \(75 mEq/L sodium, 75 mmol/L glucose\) to utilize sodium-glucose cotransport. The trap is treating dehydration as a pure volume deficit rather than an osmotic imbalance.
