With all the ads on TV and in magazines heralding pills to treat erectile dysfunction (ED), it’s tempting to think that treatment for ED begins and ends with Viagra, Levitra, and Cialis. But it’s important to be aware that many men can ease, or even reverse, ED by making simple lifestyle changes, such as losing excess weight and quitting smoking, that also are likely to boost their overall health and reduce their chances of developing diabetes, cardiovascular disease, and metabolic syndrome. This Special Health Report, Erectile Dysfunction, offers a comprehensive review of these treatments, as well as the causes of erectile dysfunction and how ED may be an early warning sign for other serious health problems.
