The most common physical cause of EPs relates to the health of the heart and blood vessels.
Cardiovascular disease can lead to the build-up of fatty deposits in the blood vessels of the penis. It is then more difficult to achieve or sustain an erection as blood is less able to flow to the penis.
In some cases, erection problems can be a warning sign of cardiovascular disease.
High blood pressure
Hypertension damages the lining of blood vessels, including those in the penis. Which can have a lasting effect on erections as blood is restricted, and blood vessels fail to open up adequately to allow sufficient blood flow into the penis.
This can clog up the blood vessels and prevent enough blood flow to the penis for an erection.
Diabetic men are at a high risk of developing erection problems as the high blood glucose levels may damage blood vessels and nerves, including those in the penis.
Men who are overweight have a higher chance of developing heart disease, as well as other conditions which can affect blood flow to the penis.
