High blood pressure (also known as hypertension) can cause erectile dysfunction, as it puts strain on your blood vessels, potentially causing damage.
In order to get an erection, your blood vessels need to open up and allow blood flow into the penis, so damage to your blood vessels can affect your ability to get an erection.
Lowering your high blood pressure could help to ease your ED, so we’d recommend asking your doctor for advice if you’re concerned that your blood pressure could be playing a part in your impotence.
