Let’s talk about... erectile dysfunction

We explain what erectile dysfunction is, the causes of it, the links with heart and circulatory diseases and how to treat it.

Erectile dysfunction (ED), or impotence, is when a man has difficulty getting or maintaining a strong enough erection for sexual intercourse or other sexual activity. It can be caused by stress, anxiety or excessive alcohol consumption. But it can also be a symptom of an underlying condition such as atherosclerosis (narrowing of the arteries), diabetes or high blood pressure. Some medications can cause erectile dysfunction, for example beta-blockers and diuretics (commonly used to treat a variety of heart-related conditions such as high blood pressure and heart failure).

Why is erectile dysfunction as a warning sign for heart disease?

During an erection, the arteries carrying blood to the penis dilate and more blood flows into the penis, causing it to swell.

If arteries in the body are affected by atherosclerosis, this causes a reduction in the blood flow, which can mean problems getting or maintaining an erection.
