Yes, in many cases, ED can be an early warning sign of cardiovascular issues. Erections rely on good blood flow, so if the blood vessels are narrowed or damaged—like in heart disease—it can lead to ED. Sometimes, ED shows up years before other heart symptoms like chest pain or shortness of breath. If you're experiencing ED, especially if you're young or have no other symptoms, it's wise to get your heart health checked. Doctors may recommend blood pressure checks, cholesterol testing, and lifestyle changes. Taking ED seriously can lead to early diagnosis and prevention of heart disease.
