ED that is, the penis continues to be unable to achieve or maintain a sufficient erection to obtain a satisfactory sex life for more than 3 months, in 1994, the U.S. study found that the prevalence of ED in men aged 40-70 years old was 52.0%, recently, the network survey “sexual well-being” index, 3/4 netizens choose not to “sexual well-being! “Nearly 40% of people’s attitude towards erection hardness is to make do, China’s current situation: the total prevalence of ED is 26.1%, the prevalence of people aged 40 years and above is 40.2% (more than 2,000 cases of large-sample survey in 2003), China’s ED patients seeking treatment for only 17% of the patients, moderate and severe patients increased significantly. It is a condition that is closely related to a variety of chronic diseases. It is also important to look at the underlying chronic diseases that cause ED, such as diabetes, coronary heart disease, atherosclerosis, high blood cholesterol, etc., which may cause ED or hide behind ED. With the increasing improvement of people’s living standard of living, diet, lifestyle habits, drugs, etc. can bring burden or even damage to the blood vessels, this damage is not only for the large blood vessels, but also affects small blood vessels such as the penile area, sometimes the damage to the large blood vessels has not yet been exposed, but the penile blood vessels to the ED manifestation of the first grabbed the first, so that men suffering from ED, 37% of which belongs to the high-risk group of cardiovascular disease. This compares to only 17% in those without ED.” The prevalence of ED in patients over the age of 60 who have had ischemic heart disease is 59 percent, compared to 35 percent of healthy people of the same age. It has also been found that the prevalence of ED in people treated for high blood pressure is about six percentage points higher than in the general population, and that ED may be an “early warning sign” of cardiovascular disease. ED and diabetes: diabetes is a cumulative multi-organ metabolic disease, can affect the nervous, cardiovascular, urinary system, etc., is one of the closest diseases with ED. The prevalence of ED in diabetic patients is 23%-75%, which is 7 times that of non-diabetic patients. The likelihood of ED in diabetic patients within 10 years is 50%. Some experts believe that ED is even the earliest symptom of diabetes. ED and Metabolic Syndrome: Studies have shown that the risk of ED in men with hypercholesterolemia is 1.83 times higher than in normal men. Also obesity is a risk factor. ED and chronic hepatic and renal insufficiency: studies have found that the incidence of ED is as high as 45% in patients with chronic renal insufficiency; in patients with alcoholic cirrhosis, the incidence of ED is 70%. ED may be a symptom of some diseases, through the diagnosis and treatment of ED can help you to detect the potential risk of disease, is not a means of preventing the disease. If we ignore these early warning signs, we will fall into the embarrassing situation of “treating the symptoms but not the root cause”, for example, we have encountered several cases of ED patients, the only manifestation of erectile dysfunction, through our careful examination, found to be a tumor in the brain (pituitary tumor), these patients in several hospitals for nearly 2 years, spending a lot of money, taking a lot of detours. These patients spent nearly 2 years in several hospitals, spent a lot of money, took a lot of detours and delayed the treatment of their condition. Therefore, once ED occurs, please find a clinically experienced male doctor in a general hospital in time, who is able to determine the cause of ED, and can make a reasonable and correct assessment by consulting with several related departments, so as to solve the problem from the root.
