Discussing erectile dysfunction remains a sensitive topic for many individuals, yet consulting a doctor about it can be crucial. In some instances, it may serve as an early indicator of other diseases.
Achieving or sustaining an erection involves a complex interplay of physical, psychological, neurological, hormonal, and vascular factors. A misstep in any of these areas can lead to dysfunction.
Erectile dysfunction can affect anyone, regardless of age, but it is increasingly prevalent as people grow older. Between the ages of 40 and 70, the likelihood of experiencing erectile dysfunction exceeds 50 percent.
Surveys reveal that nearly 20 percent of those over 55 hesitate to seek medical advice for erectile dysfunction, which could be a significant oversight.
Cardiologist Michael Joseph Blaha suggests that “erectile dysfunction is often a hint of underlying heart disease,” as noted in a review for Johns Hopkins Medicine.

Aside from heart disease, erectile dysfunction can signal mental health disorders, type 2 diabetes, and hormonal issues. It is also commonly observed in individuals with pancreatic cancer. While erectile dysfunction does not directly cause these conditions, it may highlight underlying hormonal, vascular, or metabolic problems.
An academic book recently released by top Italian endocrinologists seeks to educate the public about these connections. Titled The Canary in the Coal Mine: Erectile Dysfunction as the Best Biomarker of Non-Communicable Chronic Diseases, it underscores the potential of erectile dysfunction as an indicator of various health concerns. Edited by sexologist Emmanuele Jannini from the University of Rome Tor Vergata, the book was published alongside the Italian Society of Andrology and Sexual Medicine.
Chapter two reviews the literature on erectile dysfunction as a specific predictor of cardiovascular disease. A meta-analysis of seven cohort studies suggests that erectile dysfunction increases the risk of cardiovascular disease by 1.4 times compared to those without the condition.
Interestingly, the vasodilating drugs used to treat erectile dysfunction, such as Viagra, were initially developed for coronary artery disease. Their benefits for erectile dysfunction were discovered accidentally, hinting at similar origins for heart disease and erectile dysfunction, both of which depend heavily on the vascular system.
The authors of The Canary in the Coal Mine point out shared risk factors for cardiovascular disease and erectile dysfunction, such as smoking and lack of exercise. Notably, erectile dysfunction often manifests years before cardiovascular problems.
Chapter three highlights a similar pattern with type 2 diabetes. Approximately 50 percent or more of men with diabetes mellitus experience poor erections, potentially indicating systemic vascular or metabolic dysfunction. Erectile dysfunction frequently occurs before the onset of diabetes, implying it could be a valuable early symptom of insulin resistance.
A review published this year by Spanish researchers suggests that erectile dysfunction might act not only as a complication of type 2 diabetes but also as an early clinical marker of cardiometabolic disease. They argue that erectile dysfunction in diabetic individuals “should be regarded as a clinically relevant marker of systemic vascular disease,” with shared mechanisms including oxidative stress, inflammation, autonomic neuropathy, and low hormone levels.
The authors of The Canary in the Coal Mine share this perspective, concluding that recognizing erectile dysfunction early in men with type 2 diabetes, and considering it an early marker of diabetes or insulin resistance, could enhance the management of both conditions.

Although the associations are compelling, this theory remains tentative until robust, randomized controlled trials verify that erectile dysfunction is an early disease marker.
New research is uncovering links between erectile dysfunction and gut conditions. Men with irritable bowel syndrome, for example, are over twice as likely to develop erectile dysfunction, according to a small study involving 133 students. Inflammatory bowel disease also appears connected to erectile dysfunction.
If proven to be a reliable health indicator, erectile dysfunction could be incorporated into routine screenings to identify those at greatest risk.
Tobias Köhler, a urologist at the Mayo Clinic, participated in a panel that released guidelines for clinicians on erectile dysfunction in 2024. The panel asserted that erectile dysfunction is not merely a “quality of life” issue but also a cardiovascular concern.
A recent study found that men with erectile dysfunction and known cardiovascular risk factors who took Viagra-like medications experienced notable health benefits. These include a 25 percent reduction in all-cause mortality, a 39 percent decrease in cardiovascular death, a 17 percent lower rate of heart failure, and a 15 percent reduction in revascularization procedures.
For this reason, Köhler advises healthcare professionals to ask patients if they are experiencing any erection difficulties, emphasizing the importance of being proactive about health.
