What Is Potassium, Plasma?
Potassium (Plasma) is a vital electrolyte that helps regulate nerve signals, muscle contractions (including the heart), and fluid balance in the body. It plays a key role in maintaining healthy blood pressure and overall cellular function.
Normal Range:
3.4 – 4.8 mmol/L
What Do Abnormal Levels Mean?
-
Low potassium (hypokalemia) can cause fatigue, muscle weakness, cramps, irregular heartbeat, and, in severe cases, life-threatening complications. It may result from fluid loss (vomiting, diarrhea), certain medications (like diuretics), or underlying health conditions.
-
High potassium (hyperkalemia) may cause muscle weakness, numbness, or dangerous heart rhythm disturbances. It’s often linked to kidney issues, medications that affect potassium balance, or excessive potassium supplementation.
Since potassium levels are tightly regulated by the kidneys, even small imbalances can be clinically significant. If your potassium level falls outside the normal range, follow up with your healthcare provider to determine the cause and next steps.
