Erectile dysfunction is a sensitive issue many people hesitate to discuss, but it’s essential to bring it up with a doctor.
In some instances, this condition can be an early indicator of more serious health problems.
Achieving and maintaining an erection relies on a complex interplay of physical, psychological, neurological, hormonal, and vascular factors—where any disruption can lead to difficulties.
Erectile dysfunction can arise from various causes and affects individuals of all ages, though it becomes increasingly common with age. Research indicates that more than 50 percent of men between 40 and 70 experience this condition frequently.
Interestingly, surveys show that nearly 20 percent of those over 55 avoid seeking medical advice regarding erectile dysfunction.
This is a potentially significant error.
“Erectile dysfunction often serves as a warning sign for underlying heart disease,” notes cardiologist Michael Joseph Blaha in a review for Johns Hopkins Medicine.
Erectile dysfunction may also indicate early signs of mental health issues, type 2 diabetes, and hormonal imbalances. Additionally, it is a common concern for those diagnosed with pancreatic cancer.
While erectile dysfunction doesn’t directly cause these health issues, it may signal hidden hormonal, vascular, or metabolic problems.
A recently published academic book by leading Italian endocrinologists aims to shed light on these connections for the general public.
Titled The Canary in the Coal Mine: Erectile Dysfunction as the Best Biomarker of Non-Communicable Chronic Diseases, it emphasizes the potential of erectile dysfunction to signal other health concerns.
Edited by sexologist Emmanuele Jannini from the University of Rome Tor Vergata, it was produced in collaboration with the Italian Society of Andrology and Sexual Medicine.
The second chapter reviews existing literature on erectile dysfunction as a specific indicator of cardiovascular disease.
For instance, a meta-analysis of seven cohort studies found that erectile dysfunction significantly increases the risk of cardiovascular disease by 1.4 times compared to unaffected individuals.
Notably, a common treatment for erectile dysfunction, the vasodilating medications like Viagra, was originally intended for treating coronary artery disease—the discovery of its efficacy for erectile dysfunction was an unexpected bonus. This suggests a possible shared origin for heart disease and erectile dysfunction, as both conditions heavily depend on a functioning vascular system.
The authors of The Canary in the Coal Mine highlight that both cardiovascular disease and erectile dysfunction share risk factors, such as tobacco use and a sedentary lifestyle.
However, erectile dysfunction often appears years before any cardiovascular issues are diagnosed.
A similar correlation exists in type 2 diabetes, discussed in chapter three.
Severe erectile dysfunction affects over 50 percent of men with diabetes mellitus, which may hint at broader vascular or metabolic complications.
Furthermore, erectile dysfunction often precedes the onset of type 2 diabetes, indicating it may serve as an early warning sign for insulin resistance.
In a recent review, researchers in Spain noted that “erectile dysfunction may not only be a complication of type 2 diabetes but also an early clinical marker of cardiometabolic disease.”
When men with type 2 diabetes experience erectile dysfunction, the review authors argue it “should be considered a significant indicator of systemic vascular disease.”
They identified shared mechanisms linking both conditions, including oxidative stress, inflammation, autonomic neuropathy, and low hormone levels.
The authors of The Canary in the Coal Mine are aligned with this perspective.
“Early identification of erectile dysfunction in men with type 2 diabetes, as well as recognizing erectile dysfunction as an early marker of type 2 diabetes or insulin resistance, offers the potential to enhance understanding and treatment of both conditions,” they conclude.

While these associations are compelling, more high-quality, randomized controlled trials are needed to confirm that erectile dysfunction reliably indicates broader health issues.
Emerging studies are also uncovering links between erectile dysfunction and gastrointestinal conditions.
For example, men with irritable bowel syndrome are shown to be more than twice as likely to suffer from erectile dysfunction, according to a small study involving 133 students.
Similarly, inflammatory bowel disease has been associated with erectile dysfunction.
If erectile dysfunction becomes recognized as a reliable indicator of overall health, it could be integrated into regular health screenings to alert those at risk.
Mayo Clinic urologist Tobias Köhler took part in a panel that released guidelines for clinicians regarding erectile dysfunction in 2024. The panel stressed that this issue represents not just a “quality of life” concern, but also a cardiovascular one.
In a recent population study, men with erectile dysfunction and known cardiovascular risk factors who used PDE5 inhibitors experienced remarkable health benefits, including a 25 percent reduction in overall mortality, a 39 percent drop in cardiovascular mortality, a 17 percent reduction in heart failure, and a 15 percent lower rate of revascularization (a procedure aimed at restoring blood flow).
This is part of the reason Köhler actively encourages healthcare providers to ask their patients: “Are you experiencing any issues with erections?”
There’s no shame in taking charge of your health.
