When a man experiences sexual arousal, the blood vessels in the penis begin to expand. This lets more blood to flow rapidly into the penis. At the same time, the veins that usually take blood away from the penis become compressed, restricting the blood flow out of the penis. With more blood flowing in and less flowing out, the penis enlarges, resulting in erection. Cause for erectile dysfunction Contrary to the belief that Ed is a psychological issue and part of getting older, majority of Ed cases are associated with physical conditions.
Complications of diabetes can restrict blood flow to the penis.
When diabetes is poorly controlled, Ed can occur temporarily until the right medication is taken or the proper changes in diet are made. In other cases where a man has had diabetes for many years, Ed may not be reversible, but it can be treated. Since men with type 1diabetes generally have diabetes for a longer period, they are more likely to be affected by ED at an earlier age. On the contrary, since type 2 diabetes develops only during adulthood, men with this condition are more likely to experience ED later in life. Treatment Regardless of the cause, majority of cases of Ed are treatable.
