You delight in a low blood pressure, but when your diastolic pressure (represented by the bottom number in your blood pressure reading) is low, you may be at risk for the following:

  • Increased mortality if you have chronic kidney disease

Diastolic blood pressure measures the pressure within your arteries as it flows through them. It’s the pressure between heartbeats, that is, when your heart is at rest. Your systolic blood pressure (represented by the top number in your blood pressure reading) measures the amount of pressure that your blood exerts on vessels when your heart contracts or ‘beats’.

“Isolated diastolic hypotension” (IDH) is a condition that occurs when your diastolic blood pressure is low (less than 60 mm Hg), but your systolic blood pressure is 100 mm Hg and above.

If you’ve been congratulated for having a good systolic blood pressure (less than 120 mm Hg — or even less than 130 mm Hg), don’t be so quick to start your celebratory dance.
