Background   Bleeding disorders vary in prevalence. While some are rare, some can be common in both sexes. Most bleeding disorders manifest as chronic bleeding tendencies or as an increase in bleeding during surgical procedures or trauma. The consequences of bleeding can be as simple as iron deficiency or catastrophic, resulting in severe morbidity and mortality. Bleeding disorders typically affect both sexes except hemophilia A and B, which mainly affects males.Method   We conducted a questionnaire-based survey among adolescents and young adults (1901 [49%] boys, 1980 [51%] girls) in Riyadh city regarding bleeding symptoms. Of these, 1849 (47.6%) responded “Yes/Positive” for at least one question about the bleeding symptoms.Results   The most common bleeding symptom was epistaxis (19.7% of the sample population) detected in Phase I of the study. A tandem survey was conducted among 525 adolescents who had responded “Yes/Positive” to any one of the questions inquiring about bleeding symptoms.Conclusion   In this study, we report for the first time the prevalence of bleeding symptoms in a representative sample of Saudi adolescents and young adults.
