Diabetes is known to sabotage two body parts that provide essential components of an erection: nerves and blood vessels. Studies suggest that diabetic nerve damage (neuropathy) is the most important risk factor for ED in people with diabetes. If pelvic nerves that trigger penis muscles to relax are impaired, there may be a break in the chain between brain and penis, disrupting erection. Some researchers suspect that an inadequate supply of oxygen to the nerves causes this damage.

The choice is yours. You do not have to die of a heart attack, and you do not have to have erectile dysfunction. Both are the result of dietary choices, and you can make a choice right now to protect your life. Do you want to die of a heart attack or don’t you? If you don’t, then are you willing to do what it takes to reduce your risk almost 100 percent? I don’t know about you, but for me, just dropping my risk 20 to 40 percent with medical care is not enough. I want maximum protection.
Erectile dysfunction can be a symptom of heart disease. An erection is caused by engorgement of blood into the penile tissues which later becomes rigid for penetration. Men with heart problem suffer from an inadequate blood flow to the smooth tissues of the penis to achieve erection. A major cardiovascular disease known as Atherosclerosis is a result of fat accumulation in the arterial blood vessels. This build up of multiple plaques or fatty material causes the arteries to narrow and harden thus limiting blood flow. The arteries supplying your penis are smaller than those supplying your heart. In fact, ED can be an initial symptom of heart diseases like Atherosclerosis. Cardiovascular problems can also damage penile nerves and arteries, inhibiting erectile function. Experts found a consistent link between ED and heart disease. Other recent research conducted by health professionals has shown a direct connection between erection dysfunctions and heart problems.

Table 1 offers elements for distinction between organic and psychogenic disease.7 Of note is that in cases of organic origin, a psychogenic component may co-exist. The most common organic aetiology of ED is vasculogenic (see below ‘ED and CAD: common pathophysiology’).2,3 Co-existence of vascular disease, advancing age, and the presence of CVD risk factors and metabolic disorders increase the likelihood that ED is of vasculogenic aetiology.

Yet another common erectile dysfunction treatment that can be used in combination with oral drugs is a vacuum pump. This device consists of a plastic cylinder, a pump, a set of constriction bands, and a water-soluble lubricant. The lubricant is applied to the base of the penis to help form an airtight seal. The cylinder is placed over the flaccid penis and held tight against the pelvis. The pump is used to create a vacuum within the cylinder, drawing blood into the penis. Once the penis is engorged with blood, a constriction band is rolled off the cylinder to near the base of the penis. The constriction band is helpful for men with venous leakage, in which blood flows out of the penis as fast as it flows in. However, it should be left on for no more than 30 minutes at a time.
