Persons with metabolic syndrome can be identified by a distinct pattern of abdominal obesity (waist circumference >40 inches in men), atherogenic dyslipidemia (triglycerides ≥150 mg per 100 ml, HDL <40 mg per 100 ml, small LDL particles and normal or slightly elevated LDL), hypertension (≥130/85 mm Hg), insulin resistance (fasting blood glucose ≥10 0 mg per 100 ml), and elevated levels of prothrombotic and proinflammatory markers. Metabolic syndrome and insulin resistance are closely linked to ED. In one recently conducted study of 120 men with ED and no evidence of diabetes, 40% of patients fulfilled strict criteria for metabolic syndrome, and 73% were insulin resistant.12
In addition, when research has shown a nutrient such as zinc or niacin to improve sexual function, it's usually in people who are deficient in it. So, before you stock up on over-the-counter nutritional supplements for ED, speak with your doctor. He can test you for deficiencies and steer you toward the most effective and safest way to treat your erectile dysfunction.
If you have symptoms of ED, it’s important to check with your doctor before trying any treatments on your own. This is because ED can be a sign of other health problems. For instance, heart disease or high cholesterol could cause ED symptoms. With a diagnosis, your doctor could recommend a number of steps that would likely improve both your heart health and your ED. These steps include lowering your cholesterol, reducing your weight, or taking medications to unclog your blood vessels.
