Overview

Hyperkalemia is a laboratory finding that is a result of several conditions. These conditions must be differentiated as a cause of hyperkalemia. The following table summarize the differentiating features of causes of hyperkalemia.

Differential Diagnosis

Hyperkalemia is a laboratory finding that is a result of several conditions. These conditions must be differentiated as a cause of hyperkalemia. The following table summarize the differentiating features of causes of hyperkalemia

Organ system Conditions Distinguishing features Additional findings
Symptoms Signs Labs
Renal Acute kidney injury[1] Nausea, vomiting, decreased urine output, fatigue, dyspnea, edema Tremor, confusion, edema Hyperkalemia, increased BUN and Cr, metabolic acidosis Recently developed symptoms
Chronic kidney disease[2] Nausea, vomiting, decreased urine output, fatigue, dyspnea, edema Tremor, confusion, edema Hyperkalemia, increased BUN and Cr, metabolic acidosis, hypocalcemia, hyperphosphatemia Chronic underlying disease (DM, HTN), duration of symptoms ≥ 3 months
Renal tubular acidosis type-4[3] Usually asyptomatic Signs of underlying disease Hyperkalemia, normal anion gap metabolic acidosis, urine PH< 5.5 History of diabetes mellitus
Endocrine DKA[4] Change in mental status, abdominal pain Decreased skin turgor, dry oral mucosa, tachycardia Hyperglycemia, increased anion gap metabolic acidosis, ketonemia Rapidly developing polyuria, polydipsia, and weight loss
HHS[5] Change in mental status, abdominal pain Decreased skin turgor, dry oral mucosa, tachycardia Severe hyperglycemia, normal anion gap, increased serum osmolality Polyuria, polydipsia, and weight loss develop more insidious
Congenital adrenal hyperplasia (CAH)[6][7] Poor feeding, failure to thrive, precocious puberty, short statue, hirsutism, weight loss Ambiguous genitalia, hypotension Hyperkalemia, increased 17 hydroxyprogestrone, hyponatremia Salt wasting
Addison's disease Skin hyperpigmentation, fatigue, salt craving, nausea and vomiting, amenorrhea, depression Hyperpigmentation, hypotension, pubic and axillary hair loss Hyperkalemia, decreased serum cortisol level Diagnosis by cosyntropin test
Tissue break down Tumor lysis syndrome[8] Fever, weight loss, symptoms related to underlying malignancy Altered mental status, lymphadenopathy, muscle weakness Hyperkalemia, hyperphosphatemia, hypocalcemia History of underlying malignancy
Rhabdomyolysis[9] Myalgia, fatigue Altered mental status, hypotension Hyperkalemia, increased muscle enzymes (CK, aldolase) History of seizure, drug overdose, or trauma
