In this concise monologue, Dr. Anne Truong explains that the most common cause of erectile dysfunction (ED) is not an irreversible medical condition but reversible lifestyle factors. She identifies excessive alcohol consumption as the number‑one culprit, defining “too much” as more than two drinks per day or over fourteen drinks per week. She then cites smoking as the second major factor, noting that even one or two cigarettes can be harmful. Truong describes how both alcohol and tobacco are foreign substances that trigger systemic inflammation, which in turn damages blood vessels and impairs the blood flow essential for achieving an erection. The overall message is that by modifying these habits, men can potentially reverse ED.
