By anatomical definition, haemorrhoidal arteriovenous vascular plexuses are normal structures that surround the distal rectum and anal canal and are present from birth. Because of their rich vascular supply, highly sensitive location and tendency to engorge, haemorrhoids become symptomatic when enlarged, inflamed, thrombosed or prolapsed. Symptoms can range from mildly bothersome, such as pruritus, to quite concerning, such as rectal bleeding. The development of painful or bleeding haemorrhoids is related to a combination of venous engorgement and weakening of the supportive scaffold of connective tissue that supports these vascular structures and the overlying mucosa. In the United States, up to one‐third of the 10 million people with haemorrhoids seek medical treatment, resulting in 1.5 million related prescriptions per year.
This study detected a novel association between ED and prior haemorrhoids which was particularly prominent among those aged less than 40 years. We hope that the results of this study will encourage clinicians dealing with patients afflicted with haemorrhoids to inform their patients about their increased risks of suffering from ED. Future studies will be needed to elucidate the mechanisms underpinning the association detected in this study.
