Some diseases associated with erectile dysfunction

The most common cause for erectile dysfunction is impaired blood flow into the penis, which is a common result of arteriosclerosis and diabetes. In fact, in about forty percent of all people over the age of 50, erectile dysfunction is caused directly by arteriosclerosis. About 50% of all people suffering from diabetes (insulin dependent) suffer from some form of erectile dysfunction.

Erectile dysfunction is defined as the inability to achieve or maintain an erection sufficient for mutually satisfying intercourse. Erectile dysfunction impacts more than a man's sexual activity. The emotions that coincide with this condition often have a significant effect on a man's self-esteem, as well as on his relationship with his partner. Although the incidence of erectile dysfunction increases with age, it is not an inevitable result of ageing. For the elderly and for others, erectile dysfunction may occur as a consequence of specific illnesses or of medical treatment for certain illnesses.

The most frequent physical causes of erectile dysfunction are vascular diseases including arteriosclerosis, hypertension, hypercholestremia and other conditions that interfere with the blood flow to the penis. Because adequate arterial supply is critical for erection, any disorder that impairs blood flow may be implicated in the etiology of erectile failure. Some diseases associated with erectile dysfunction can affect both the vascular and the nervous systems. Diabetes is an example.

Hypertension in patients with diabetes frequently manifests certain unique and challenging properties. For example, persons with type 2 diabetes often lose their normal circadian rhythm of blood pressure and heart rate. Loss of normal nocturnal drops in blood pressure and heart rate may reflect both autonomic dysfunction and/or decreased sensitivity of renal-neural sensing of volume-pressure relationships. Disproportionate elevations of nocturnal blood pressure, especially systolic blood pressure, increase the 24-hour integrated cardiovascular and renal load, are more clearly associated with albuminuria and left ventricular hypertrophy, and thus greatly increase CVD risk as well as progression of renal disease in these patients.

Diabetes results in poor circulation and/or peripheral neuropathy. When the nerves are involved sexual stimuli are not transmitted appropriately to or from the brain and erectile dysfunction develops.

Research has resulted in significant advances in both the diagnosis and treatment of erectile dysfunction. Physicians now understand that approximately 84 % of erectile dysfunction is attributable to physical conditions while only fifteen percent is due to psychological conditions.

Prescription medications often cause erectile dysfunction as a side effect. Many medications fall into this category including antidepressants, antipsychotics, treatments for cancer of the prostate, chemotherapy and some antihypertensives notably beta-blockers, diuretics and ace Inhibitors/ calcium channel blockers, However, as many cases of erectile dysfunction are caused by personal reactions to specific medications, a change of prescription to another class of medication is often all that is needed to correct the condition.
