In the United States diabetes and obesity are responsible for 8 million cases of erectile dysfunction. Scientific evidence indicates that excessive body weight should be considered as an independent risk factor for erectile dysfunction. This risk increases with increasing BMI. [1]

The obesity affects around 312 million people over the world. In The United States it causes more than 300 000 deaths per year. It leads to many complications, such as ischemic heart disease, hypertension, dyslipidemia, atherosclerosis and abnormal carbohydrate metabolism. It was proven recently that obesity is also an independent risk factor for erectile dysfunction in men. 79% of men presenting erectile disorders have BMI of 25 kg/m2 or greater. BMI in the range 25-30 kg/m2 is associated with 1,5 times, and in the range of over 30 kg/m2 with 3 times greater risk of sexual dysfunction. [2]

The occurrence of erectile dysfunction in patients with obesity is caused by a number of complications which are characteristic for an excessive amount of fat tissue, in example: cardiovascular diseases, diabetes or dyslipidemia.. Erectile disorders correlate with the occurrence of obesity at any time during the patient’s life. Obesity leads to erectile dysfunction in a considerably greater extent than aging. Mechanisms responsible for the independent influence of obesity on the erectile dysfunction are: hormonal imbalance, endothelial dysfunction, insulin resistance, psychological factors and physical inactivity. The basis for erectile dysfunction treatment in obesity is body weight loss. Erectile disorders in obese men are significantly more frequent than in general population. Obesity is beyond any doubts an independent risk factor of erectile dysfunction.

Scientific study shows the overall prevalence of erectile dysfunction in men aged >/=20 years was 18.4% (95% confidence interval [CI], 16.2-20.7), suggesting that erectile dysfunction affects 18 million men (95% CI, 16-20) in the US. There is no scientific study in Vietnam showing the exact number of erectile dysfunction but if we use this prevalence in the population of Vietnam, we can count the number of nearly 10 million cases of ED. [3].

Obesity has become a worldwide public health problem of epidemic proportions, as it may decrease life expectancy by 7 years at the age of 40 years: excess bodyweight is now the sixth most important risk factor contributing to the overall burden of disease worldwide. Moreover, women with the metabolic syndrome have an increased prevalence of sexual dysfunctions as compared with matched control women. Lifestyle changes aimed at reducing body weight and increasing physical activity induce amelioration of both erectile and endothelial functions in obese men. Moreover, preliminary evidence suggests that a Mediterranean-style diet might be effective in ameliorating sexual function in women with the metabolic syndrome. Lifestyle changes, mainly focussing on regular physical activity and a healthy diet, are effective and safe ways to reduce cardiovascular diseases and premature mortality in all population groups; they may also prevent and treat sexual dysfunctions in both sexes.
