Living with Familial hyperaldosteronism

A group of inherited conditions in which the adrenal glands make too much aldosterone, causing high blood pressure.

Understanding Familial hyperaldosteronism

Familial hyperaldosteronism is a group of inherited conditions in which the adrenal glands make too much of the hormone aldosterone.

Excess aldosterone makes the kidneys hold on to salt, raising fluid levels and blood pressure. People can have severe high blood pressure, often early in life. There are three types, based on features and genetic cause. Type I can be treated with steroid medicine (glucocorticoids). Type III often has enlarged adrenal glands and severe high blood pressure starting in childhood.

Signs & symptoms

GARD describes this main symptom in its summary:

  • High blood pressure (hypertension), sometimes severe
  • High blood pressure that starts in childhood in some types
  • Enlarged adrenal glands in type III

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include genetic specialists, hormone specialists and kidney specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
