What Is High Potassium (Hyperkalemia)?
Potassium plays an important role in supporting nerve and muscle function, including the heart.
When blood potassium levels become higher than normal, it may:
Affect Heart Rhythm
- May interfere with normal electrical activity (irregular heartbeat).
- Increases the risk of death.
Cause Muscle Weakness
- May affect muscle contraction and strength.
Lead to Heart Complications
- May cause life-threatening problems such as cardiac arrest (heart suddenly stops beating).
Many individuals may not experience noticeable symptoms in the early stages.
You May Be At Higher Risk If You Have:
Kidney Problems
Kidney remove excess potassium from the body
High Blood Pressure
Especially if on certain medications
Diabetes
Long term diabetes may affect kidney function over time
Heart Conditions
Some heart medicines affect potassium levels
If you have one or more of these conditions, consider speaking to a healthcare professional for appropriate consultation.
Possible Symptoms
High potassium does not always cause obvious symptoms. When symptoms occur, they may include:
Muscle Weakness
Tingling Sensation
Fatigue
Palpitations
Prevention & Monitoring
Taking steps early may help manage potassium levels and reduce potential risks.
Regular Monitoring
Regular monitoring of potassium levels helps detect changes early and guide appropriate management.
Kidney Function Screening
Routine screening of eGFR and UACR helps detect chronic kidney disease (CKD) early and may help reduce the risk of hyperkalemia.
Lifestyle & Dietary Management
Managing dietary potassium intake and reducing sodium may help support overall health and potassium balance.
