By Medically reviewed by hellodoktor


What is high potassium?

Potassium is an essential electrolyte, which is a mineral your body needs to function correctly. Potassium is especially important for your nerves and muscles, including your heart. While potassium is important to your health, getting toomuch of the nutrient can be just as bad as, or worse than, not getting enough. Normally, your kidneys keep a healthy balance of potassium by flushing excess potassium out of your body. But for many reasons, the level of potassium in your blood can get too high. This is called hyperkalemia, or high potassium.

Your blood potassium level is normally 3.6 to 5.2 millimoles per liter (mmol/L). Having a blood potassium level higher than 6.0 mmol/L can be dangerous and usually requires immediate treatment.

What causes high potassium?

  • Other health conditions. High potassium can also be linked to certain health problems, such asdehydration, type 1 diabetes, Addison’s disease, and internal bleeding.
  • Medications. Certain medications have been linked with high potassium levels. These includecertain chemotherapy drugs, angiotensin-converting enzyme (ACE) inhibitors, angiotensin receptor blockers, among others.
  • Supplements. Overuse of potassium supplements can increase your potassium levels to a range that’s higher than normal or even dangerous.
  • Alcohol or drug use. Heavy alcohol or drug use can cause your muscles to break down. This breakdown can release a high amount of potassium from your muscle cells into your bloodstream.
  • Trauma. Certain kinds of trauma can raise your potassium levels as well. In these cases, extra potassium leaks from your body cells into your bloodstream. Burns or crush injuries where a large number of muscle cells are injured can cause these effects.

The conditions mentioned above are some common causes of high potassium. Consult with your doctor for an accurate diagnosis.
