❓ Frequently Asked Questions
Q: What is the normal range for potassium levels?
A: The normal range for potassium is typically between 3.5 and 5.0 milliequivalents per liter (mEq/L).
Q: What are the main causes of hypokalemia?
A: Common causes of hypokalemia include certain medications (like diuretics), vomiting, diarrhea, and poor dietary intake.
Q: How does hypokalemia affect the heart?
A: Hypokalemia can lead to various cardiac arrhythmias and ECG changes, potentially causing serious complications.
Q: What are the symptoms of low potassium?
A: Symptoms of hypokalemia can include muscle weakness, fatigue, constipation, and heart palpitations.
Q: How is hypokalemia treated?
A: Treatment for hypokalemia usually involves potassium supplementation, either orally or intravenously, depending on the severity.
Q: Can high potassium levels (hyperkalemia) be dangerous?
A: Yes, hyperkalemia can be just as dangerous as hypokalemia and can also lead to cardiac arrhythmias and other serious health problems.
