Is elevated potassium dangerous?

What happens when potassium levels spike? Hyperkalemia means that the level of potassium in the blood is elevated. Potassium is a vital electrolyte that helps regulate heart rhythm and muscle function. When levels exceed 5.6 mmol/L, it can become dangerous and, in severe cases, lead to cardiac arrest.

Quick version

Potassium is an essential electrolyte that helps regulate heart rhythm, muscle contractions, and nerve impulses. Most potassium is found inside the body’s cells and works in balance with other electrolytes to maintain stable fluid levels and normal cell function. The right amount of potassium is crucial for proper muscle and nerve activity and for keeping your heart beating steadily.

What happens when potassium levels are elevated?

High potassium levels result in a condition called hyperkalemia, which disrupts the body's electrical balance. Potassium is vital for heart and muscle function, and elevated levels can lead to serious issues such as heart rhythm disturbances, muscle weakness, and, in severe cases, cardiac arrest. When potassium levels in the blood exceed 5.6 mmol/L, the risks increase significantly. In severe cases, respiratory muscles may also be affected, leading to breathing difficulties. Hyperkalemia often requires immediate treatment to prevent life-threatening complications.

How to determine If you have elevated potassium levels

The only way to accurately determine if you have elevated potassium levels is through a blood test. This is especially important for individuals with kidney disease, diabetes, or those taking medications that affect kidney function. Regular monitoring of potassium levels can help detect problems early and prevent complications. With us, you can easily order a potassium test via referral. Our tests are analyzed by accredited laboratories, and you will quickly receive a clear overview of your levels along with recommendations based on the results.

Seek medical care for elevated potassium levels

If a blood test shows elevated potassium levels, it is important to act promptly. Start by contacting your doctor for an evaluation and further investigation. Treatment depends on how high your potassium levels are and the underlying cause of the elevation.

In severe cases, emergency treatment may be necessary. This can include intravenous calcium to protect the heart, insulin with glucose to move potassium back into the cells, or potassium-binding medications to help the body eliminate the excess. For milder cases, adjustments to medications or dietary changes may be enough to bring levels under control. It is essential to reduce the intake of potassium-rich foods such as bananas, oranges, avocados, and nuts if recommended by your doctor.

Can hyperkalemia be prevented?

Yes, there are several ways to reduce the risk of hyperkalemia and keep your potassium levels in check. Here are some practical tips:

  • 1. Monitor your potassium levels regularly.
  • 2. Follow a balanced diet and avoid excessive consumption of potassium-rich foods.
  • 3. Stay hydrated.
  • 4. Consult about medications such as ACE inhibitors, ARBs, or potassium-sparing diuretics.
