Endocrine, nutritional, and metabolic diseases (E00-E90).
- Diabetes mellitus (diabetes).
- Gordon syndrome (synonym: pseudohypoaldosteronism type 2) – rare genetic form of hypertension (high blood pressure) characterized by hyperkalemia, mild hyperchloremic metabolic acidosis (metabolic acidosis), normal or elevated aldosterone, low renin with normal glomerular renal filtration rate (GFR).
- Hyperglycemia (high blood sugar).
- Hypoaldosteronism (primary and secondary; Addison’s disease) – decrease in blood aldosterone, which regulates electrolyte (salt)-water balance.
- Metabolic acidosis/metabolic acidosis (especially chloracidosis).
- Adrenocortical insufficiency (NNR insufficiency; adrenocortical insufficiency), primary
- Pseudohypoaldosteronism, renal, type 1 – very rare genetic metabolic disorder with autosomal dominant inheritance or even sporadic cases, occurring as a mild form of primary mineralocorticoid resistance confined to the kidney; it is associated with hypotension (low blood pressure), hyperkalemia, and metabolic acidosis (metabolic acidosis), among other symptoms; age of manifestation: infant age, neonatal period.
Psyche – nervous system (F00-F99; G00-G99).
- Alcohol abuse (alcohol abuse)
Genitourinary system (kidneys, urinary tract – reproductive organs) (N00-N99).
- Renal insufficiency, chronic (process leading to a slowly progressive reduction in renal function) (33-88% of cases)
- Acute renal failure
Other differential diagnoses
- Fasting
- Alimentary: increased intake of potassium; hyperkalemia due to increased dietary potassium intake occurs only in patients with impaired renal function
- Tissue breakdown (hemolysis/dissolution of red blood cells, trauma/injury, tumors, radiation therapy).
