What causes erectile dysfunction?

ED can have both physical and psychological causes. Physically, common causes include heart disease, high blood pressure, diabetes, obesity, and low testosterone. Poor blood flow or nerve damage can also lead to ED. Psychologically, stress, anxiety, depression, or relationship problems may play a role. Sometimes it’s a mix of both. Lifestyle factors like smoking, alcohol use, lack of exercise, and poor diet can make ED worse. Identifying the root cause with the help of a doctor is key to effective treatment. Don’t ignore ED—it may be your body’s way of signaling a deeper issue.
