- Acidemia (see DKA)
- Cellular breakdown: see Rhabdomyolysis/Crush syndrome, electrical/thermal burn, hemolysis, see Tumor lysis syndrome
Increased total body potassium
- Inadequate excretion: Acute/chronic renal failure, Addison's disease, type 4 RTA
- Drug-induced: potassium-sparing diuretic (spironolactone), angiotensin converting enzyme inhibitors (ACE-I), nonsteroidal anti-inflammatory drugs (NSAIDs)
