What is Potassium?

Potassium is an essential mineral and electrolyte that plays a crucial role in various bodily functions, including the regulation of heart rate, blood pressure, water balance in the body, and the proper function of nerves and muscles.

Why should you have Potassium tested?

Testing potassium is important to monitor potassium levels in the blood. This can be particularly useful for people with kidney diseases, heart problems, or for those using medications that affect potassium levels. It can also be helpful in diagnosing the cause of symptoms such as muscle weakness, fatigue, or heart rhythm disorders.

What does it indicate?

A potassium test indicates the amount of potassium in the blood. A balanced potassium level is essential for maintaining normal cellular functions and for overall health.

What does a high potassium level mean?

A high potassium level, known as hyperkalemia, may indicate kidney failure, excessive potassium intake, or certain medications. It can lead to serious health problems, including heart problems and potentially life-threatening cardiac arrhythmias.

What does a low potassium level mean?

A low potassium level, known as hypokalemia, can result from insufficient dietary potassium intake, loss through urine or sweat, or conditions like diarrhea. Symptoms may include muscle weakness, cramps, fatigue, and heart rhythm disorders.
