Warning Signs May Reveal Hidden Adrenal Tumour Conditions
Primary aldosteronism is a condition in which the body makes too much of a hormone called aldosterone.
It is also known as Conn’s syndrome.
An adrenal tumour or another abnormality can sometimes cause it.
Aldosterone helps control blood pressure and potassium levels.
Blood pressure that stays high despite several medicines may be a warning sign.
Unexplained low potassium may provide another clue.
These signs do not prove that someone has an adrenal tumour.
They may show that further medical investigation is needed.
Primary aldosteronism, also called Conn’s syndrome, involves excessive production of aldosterone.
An adrenal tumour or another abnormality can cause primary aldosteronism.
Aldosterone helps regulate blood pressure and potassium levels.
Persistently high blood pressure despite multiple medications may warrant evaluation for excess aldosterone.
Unexplained low potassium alongside difficult-to-control blood pressure can be an important clue, but does not automatically indicate an adrenal tumour.
- Who
- People with persistently high blood pressure, especially when it occurs with unexplained low potassium.
- What
- Primary aldosteronism, or Conn’s syndrome, may result from an adrenal tumour or another abnormality that causes excess aldosterone production.
- When
- Not specified in the article.
- Where
- Not specified in the article.
- Why
- To investigate whether excess aldosterone is contributing to difficult-to-control blood pressure or low potassium.
- Condition
- Primary aldosteronism, also known as Conn’s syndrome.
- Possible cause
- An adrenal tumour or another abnormality.
- Hormone involved
- Aldosterone.
- Hormone function
- Aldosterone helps regulate blood pressure and potassium levels.
- Potential warning sign
- Blood pressure that remains high despite multiple medications.
- Additional clue
- Unexplained low potassium.
- Important qualification
- These symptoms do not automatically indicate an adrenal tumour but may warrant further investigation.
