Symptoms
- Weakness and tiredness
- Dizziness when standing up
- Low blood pressure
- Salt craving
- Irregular heartbeat from high potassium
Causes and risk factors
Causes include kidney disease, diabetes, Addison's disease, congenital adrenal hyperplasia and medicines such as ACE inhibitors and some water tablets.
Diagnosis
Blood tests measure potassium, sodium, aldosterone and renin.
Treatment
Treatment may include adjusting medicines, a low-potassium diet, fludrocortisone and treating the underlying cause.
When to see a doctor
See a doctor if you have high potassium on a blood test. Seek urgent care for palpitations, severe weakness or fainting.
