Clarity for the path ahead.

Trusted, plain-English information for people across the UK affected by an under-recognised cause of high blood pressure.

Start hereHigh blood pressure may have an underlying hormonal cause.
The essentials

A small hormone can have a wide effect.

Aldosterone helps regulate sodium, potassium and fluid. When the adrenal glands produce too much, blood pressure can rise and potassium may fall.

Many people have no obvious symptoms and potassium can remain within the normal range. Identification matters because targeted medication or, for some people, surgery can improve blood-pressure control and reduce the effects of excess aldosterone.
