HIGH BLOOD POTASSIUM LEVEL
Hyperkalemia
A condition with high potassium levels in the blood, often due to kidney disease or medications, with significant risk of dangerous heart rhythm problems. Needs urgent evaluation and treatment.
ABOUT THIS CONDITION
What is Hyperkalemia
Hyperkalemia refers to a higher than normal level of potassium in the blood. Potassium is essential for normal heart, nerve and muscle function, and significantly elevated levels can cause dangerous heart rhythm problems, including life-threatening arrhythmias. Common causes include kidney disease (the kidneys normally excrete excess potassium), certain medications including kidney-protective therapy and potassium-sparing diuretics, adrenal insufficiency, severe tissue injury, blood transfusion, certain forms of diabetes-related illness, and excessive potassium intake in the context of impaired excretion. Typical features include muscle weakness, palpitations, irregular heartbeat, tingling and numbness, and, in severe cases, sudden cardiac arrhythmias and cardiac arrest. Many patients with mild hyperkalemia have no symptoms, and the condition is detected on blood tests. Diagnosis is confirmed by a blood test for potassium, with an ECG to assess for cardiac changes. Treatment depends on severity, rate of onset and ECG findings, ranging from medication review and dietary modification in mild cases to urgent hospital treatment with intravenous therapy and dialysis in severe cases. Dr. Patnam Pravallika Reddy provides urgent evaluation and care at Lux Hospitals, Hyderabad.

HOW WE TREAT IT
Treatment Approach
Urgent Treatment with Cause Identification
The most effective approach is urgent assessment with ECG to identify cardiac risk, immediate treatment to protect the heart and lower potassium in severe cases (intravenous therapy, dialysis when indicated), and identification and treatment of the underlying cause to prevent recurrence.
- 1
Consultation & Assessment
Dr. Pravallika reviews symptoms, medications and possible causes, examines the patient, arranges urgent blood tests and ECG to assess severity and cardiac risk.
- 2
Treatment Planning
A personalised plan is created based on severity, cause and ECG findings, with hospital admission for moderate to severe cases.
- 3
Medical Management
Urgent intravenous therapy to protect the heart and lower potassium in severe cases, medication review, dietary advice and treatment of underlying cause.
- 4
Recovery & Follow-up
Regular monitoring of potassium, medication adjustments and management of underlying conditions to prevent recurrence.
AVAILABLE TREATMENTS
Treatment Options
Urgent ECG Assessment
An ECG immediately assesses cardiac risk and need for urgent intervention; characteristic changes such as tall peaked T waves and widening QRS warn of impending arrhythmias.
Urgent Intravenous Therapy for Severe Cases
Severe hyperkalemia is treated urgently with intravenous therapy to protect the heart and shift potassium into cells while definitive treatment is arranged.
Medication Review and Adjustment
Identifying and adjusting medications contributing to hyperkalemia — including kidney-protective therapy and potassium-sparing diuretics — is essential.
Dietary Modification
Reducing high-potassium foods (bananas, citrus fruits, tomatoes, potatoes, certain green leafy vegetables) is advised in patients at ongoing risk.
Dialysis in Severe or Refractory Cases (Referral for nephrology)
Dialysis is used for severe hyperkalemia not responding to medical therapy, particularly in patients with significant kidney disease.
