    Primary hyperaldosteronism in pregnancy can cause hypertension and hypokalemia. Surgical removal of an adrenal adenoma resolved these symptoms, restoring normal blood pressure and potassium levels.

    Area of Science:

    • Endocrinology
    • Obstetrics
    • Nephrology

    Background:

    • Primary hyperaldosteronism is a condition characterized by excessive aldosterone secretion.
    • Hypertension and hypokalemia are common clinical manifestations.
    • Pregnancy can unmask or exacerbate underlying endocrine disorders.

    Observation:

    • A 37-year-old pregnant woman presented with early-onset hypertension and hypokalemia.
    • Diagnostic tests revealed suppressed plasma renin concentration and elevated recumbent plasma aldosterone.
    • These hormonal imbalances persisted throughout gestation and into the postpartum period.

    Findings:

    • The patient underwent successful left adrenalectomy for a confirmed left-sided adrenal adenoma.
    • Post-surgery, the patient normalized blood pressure and serum potassium levels without medication.

  • Urinary aldosterone levels also returned to normal within a week of the procedure.

    • Implications:

    • This case highlights the importance of considering primary hyperaldosteronism in pregnant women with unexplained hypertension and hypokalemia.
    • Early diagnosis and surgical intervention can lead to favorable maternal and fetal outcomes.
    • Adrenalectomy is an effective treatment for primary hyperaldosteronism, even in the postpartum period.
