Lithium (priadel, camcolit, lithium carbonate) — Lithium and sodium compete in your kidneys. Big changes in salt or fluid intake directly swing lithium levels.
Keep salt and fluid intake consistent. Sudden low-salt diets raise lithium levels (toxicity risk); sudden high-salt binges lower them (losing effect). Dehydration — illness, heat, exercise, alcohol — is the biggest danger. Never start a low-sodium diet without your team adjusting monitoring.
