A detailed history can help interpret the cause of hypokalemia. Special focus should be on medication intake and past medical conditions. Medical conditions such as, uncontrolled [[diabetes]], [[hyperthyroidism]], [[pernicious anemia]], [[COPD]], [[Cushing's disease]], [[primary hyperaldosteronism]], [[Liddle's syndrome]], Barter's syndrome, [[Gitelman syndrome|Gittelman syndrome]] and [[renal tubular acidosis]] can all lead to hypokalemia. Common [[symptoms]] of hypokalemia include [[nausea]], [[vomiting]], [[constipation]] ([[ileus]]), [[muscle cramps]], [[myalgias]] and [[generalized weakness]]. Less commonly, severe hypokalemia may lead to [[cardiac]] conduction problems and may present as fainting or [[palpitations]]. | |||

Overview
A detailed history can help interpret the cause of hypokalemia. Special focus should be on medication intake and past medical conditions. Medical conditions such as, uncontrolled diabetes, hyperthyroidism, pernicious anemia, COPD, Cushing's disease, primary hyperaldosteronism, Liddle's syndrome, Barter's syndrome, Gittelman syndrome and renal tubular acidosis can all lead to hypokalemia. Common symptoms of hypokalemia include nausea, vomiting, constipation (ileus), muscle cramps, myalgias and generalized weakness. Less commonly, severe hypokalemia may lead to cardiac conduction problems and may present as fainting or palpitations.
History and Symptoms
History
A detailed history can help interpret the cause of hypokalemia.
Dietary History
Malnutrition: lack of adequate calorie intake
Medication History
- Diuretics (loop and thiazides)
- Beta-agonists
- Chloroquine
- Theophylline
- Insulin
- Corticosteroids
- Licorice
- Nephrotoxic drugs (platinum-based chemotherapy, aminoglycosides)
- Laxatives
Past Medical History
- Uncontrolled diabetes
- Hyperthyroidism
- Pernicious anemia
- COPD (treated with Beta agonists and theophylline)
- Cushing’s disease
- Periodic paralysis
- Ileostomy/short bowel
- Primary hyperaldosteronism
- Liddle syndrome
- Bartter and Gitelman syndrome
- Prolonged starvation
- Cancer
- Renal tubular acidosis type I and type II
Symptoms
The severity of symptoms depends on the degree of hypokalemia, but keep in mind that there is marked individual variability [1][2][3][4].
Constitutional
- Fatigue
- Weakness
- Vomiting
- Constipation
- Muscle cramps and paralysis (the lower extremity muscles are most commonly involved) which may involve the intestine and cause ileus
- Respiratory muscle weakness leading to respiratory failure.
Cardiac
- Hypertension
- Arrhythmias including premature atrial and ventricular complexes, paroxysmal atrial or junctional tachycardia and even ventricular tachycardia or fibrillation
- Heart block
- Digoxin therapy, CAD and left ventricular hypertrophy potentiate hypokalemia effects on the heart
Renal
- Nephrogenic diabetes insipidus due to decreased concentrating ability. As a consequence, the patient presents with polyuria and polydipsia
- Increased bicarbonate reabsorption
- Increased ammonia formation which may precipitate hepatic encephalopathy in cirrhotic patients
- Decreased sodium reabsorption resulting in hyponatremia
