Why does diabetes induce erectile dysfunction?
Two of the basic physical requirements for producing an erection are healthy blood vessels and healthy nerves in the penis. Because both the blood supply and nerve endings are affected by diabetes, the chances of getting and sustaining an erection are reduced in diabetics.
For reasons that are not completely understood a high glucose level, if present for years, can damage the function of muscle fibres within blood vessles and vascular tissues, including the erectile tissue of the penis, and of the small nerves and arteries throughout the body. Thus ED can affect many men with diabetes, with some studies reporting that up to 60 per cent of diabetic men will eventually develop the problem.
Although the chances of this occurring are reduced by good treatment of the diabetes they cannot be reduced to zero. A further and increasingly common problem is that the type of diabetes commoner in older people (called Type 2 or non-insulin dependent diabetes) can be accompanied by relatively few symptoms in the early stages, which mean that many people with Type 2 diabetes already show some damage to the nerves and arteries by the time they have their diabetes diagnosed.
