The American Diabetes Association recognizes the role diabetes may play in the development of erectile dysfunction. Diabetes can affect blood flow to the penis, interfering with sexual activity. It can also decrease the necessary muscle relaxation important for sexual function. Keeping diabetes under control through diet, exercise, and a healthy lifestyle will prevent erectile dysfunction caused by this disease. If your erectile dysfunction is related to diabetes, your doctor may prescribe medications to restore blood flow to the penis and improve your sex life.
While obesity doesn’t directly cause erectile dysfunction, the many negative health effects caused by obesity can interfere with sexual performance. Studies suggest that obesity is linked to erectile dysfunction due to its effects on blood pressure, cholesterol, atherosclerosis, and the increased risk of diabetes. Obesity can also contribute to erectile dysfunction through its effects on hormone balance. A negative self-image or the feelings of self-consciousness caused by obesity can also interfere with the ability to perform sexually. The CDC recommends maintaining a BMI of 18.5-24.9 for a healthy weight. An adult BMI calculator will help you determine your BMI using your height and weight.
