ED affects approximately 1 in 10 men on a chronic basis. If it occurs less than 20 percent of the time, it is normal; whereas if it occurs more than 50 percent of the time, there is a problem that requires therapy, according to the Cleveland Clinic.
There are oral medications for ED. Its prevalence has led pharmaceutical companies to saturate the airwaves. Approved medications include Viagra (sildenafil, or the “little blue pill”), Cialis (tadalafil) and Levitra (vardenafil).
These drugs work by affecting the endothelium, or inner layer, of blood vessels and causing vasodilation, or enlargement, which increases blood flow to the penis.
Unfortunately, this does not solve the medical problem, but it does provide a short-term fix.
ED’s prevalence increases with age. In a multinational MALES study, ED affected 8 percent of those aged 20 to 30 and 37 percent of 70 to 75 year olds. What was surprising was that advanced age had the least association with ED, increasing the odds by only 5 percent.
So, what contributes to the rest of the increase as we age? Disease processes and drug therapies.
Chronic diseases significantly contribute to ED – and ED may be a harbinger of disease. Typical contributors include metabolic syndrome, diabetes, high blood pressure, cardiovascular disease and obesity.
In the Look AHEAD trial, ED had a greater than two-fold association with hypertension and a three-fold association with metabolic syndrome. In another study, ED was associated with a 2.5-times increase in cardiovascular disease.
In a randomized clinical trial (RCT), patients with ED had significantly more calcification, or atherosclerosis, in the arteries when compared to a control group. They were more than three times as likely to have severe levels of calcification. They also had more inflammation, measured by C-reactive protein.
About 25 percent of ED cases are thought to be associated with medications, such as antidepressants; NSAIDs, such as ibuprofen and naproxen sodium; and hypertension medications.
Unfortunately, the most common antidepressant medications, SSRIs, have the greatest impact on ED of all antidepressants.
The California Men’s Health Study, with over 80,000 participants, showed that there was an association between NSAIDs and ED, with a 38 percent increase in ED in patients who use NSAIDs on a regular basis.
The authors warn that patients should not stop taking NSAIDS without consulting their physicians.
Also, high blood pressure drugs have a reputation for causing ED. A meta-analysis of 42 studies showed that beta blockers have a small effect, but thiazide diuretics (water pills) more than doubled ED, compared to placebo.
Prevention & Treatment
The Mediterranean-type diet has been shown to treat and prevent ED, thus improving one’s health and sex life at the same time. It is the green leafy alternative to the little blue pill.
The foods are rich in omega-3 fatty acids and high in monounsaturated fats and polyunsaturated fats, as well as in fiber. Components include whole grains, fruits, vegetables, legumes, walnuts, and olive oil.
In two RCTs lasting two years, those who followed a Mediterranean-type diet saw improvements in their endothelial functioning. They also had reduced inflammation and decreased insulin resistance.
In another study, men who had the greatest compliance with the Mediterranean-type diet were significantly less likely to have ED, compared to those with the lowest compliance. Even more impressive was that the group with the highest compliance had a 37 percent reduction in severe ED versus the low compliance group.
Therefore, it is important to bring ED to the attention of physicians. There are very effective lifestyle alternatives to oral medication that provide positive overall health effects, while also helping patients eliminate medications that contribute to ED.
