What are the causes of high potassium?

High potassium, formally known as hyperkalemia, is the condition in which the potassium level is beyond the range of 3.6 to 5.2 millimoles per liter. In general, high potassium could be “false” or genuine. The false type is due to the rupture of blood cells in the blood sample. As for the genuine type, the common causes are as follows.

Common causes:

  • Problems with kidneys: such as acute kidney failure and chronic kidney disease.
  • Addison’s disease (adrenal insufficiency)
  • Dehydration
  • Destruction of red blood cells due to severe injury or burns
  • Type 1 diabetes
  • Medications: Angiotensin-converting enzyme (ACE) inhibitors, antibiotics, beta-blockers (blood pressure drugs), potassium supplements, etc.
