High Aldosterone: Causes

High aldosterone levels can cause high blood pressure, muscle weakness, and kidney dysfunction. It is often linked to adrenal gland tumors and electrolyte imbalances. Early treatment is essential to prevent complications.

Aldosterone is a hormone secreted by the adrenal glands that helps maintain blood pressure by regulating sodium and potassium levels in the body. Healthcare professionals conduct tests to determine if a patient's aldosterone high levels may indicate the presence of a tumour or other health complications.

What Happens When Aldosterone Levels Are High?

Aldosterone high levels are medically termed hyperaldosteronism. This condition is generally caused by a benign tumour affecting the adrenal glands, which may later be referred to as primary aldosteronism or Conn's syndrome, leading to the over-secretion of aldosterone. 

High aldosterone levels cause the following effects:

  • High blood pressure results from an increased volume of blood brought about by sodium retention.
  • An electrolyte imbalance occurs that is characterised by hypernatremia or high sodium levels and hypokalemia or low potassium levels. It could be symptomatic with muscle weakness, tiredness, and increased urinary output.
  • Continuous high aldosterone causes long-term renal dysfunction.

Conclusion

Early diagnosis and treatment are essential for managing hyperaldosteronism and preventing further complications. Individuals with health insurance coverage should check whether the treatment is included in their plan to ensure they can pursue the appropriate medical intervention.
