Chloride

Linked to getting too little

Where a shortfall of Chloride is linked — 2 sources.In the order the Map holds them: strongest evidence first. That is a statement about the evidence, not about what matters most.

Chloride	Don't overdo	Moderate	Established clinical	Hyperchloremia (from dehydration, excess saline, renal dysfunction) causes hyperchloremic metabolic acidosis.	Critical-care chloride review (PMC10995984) (opens in a new tab)
Chloride	Don't overdo	Moderate	Established clinical	Hyperchloremia is associated with decreased cardiac output and impaired myocardial contractility; with sodium/fluid excess it contributes to hypertension, edema and heart failure.	Critical-care chloride review (PMC10995984) (opens in a new tab)
