High Blood Pressure
High blood pressure makes the heart work harder. This puts strain on the blood vessels, which then harden and narrow. This can prevent blood from getting to the penis which makes it more difficult to get or keep an erection.
More than 65% of men with high blood pressure also have ED.
Diabetes is a condition where there is too much sugar, or glucose, in the blood. Over time, high blood sugar levels can damage nerves and blood vessels like those that produce erections. When this occurs, diabetes often leads to ED.
Up to 85% of men with diabetes have some erection difficulty.
