Differential Diagnosis for Profuse Cervical Bleeding after Intercourse
Single Most Likely Diagnosis
- Cervicitis: This is often the most common cause of post-coital bleeding due to inflammation of the cervix, which can be caused by infections such as chlamydia or gonorrhea. The physical trauma from intercourse can exacerbate the condition, leading to bleeding.
Other Likely Diagnoses
- Cervical Ectropion: A condition where the glandular cells lining the inside of the cervical canal are everted to the outside of the cervix, making them more susceptible to bleeding, especially after intercourse.
- Cervical Polyps: These are growths on the cervical canal that can cause bleeding, especially after sexual intercourse, due to the mechanical trauma.
- Vaginal or Cervical Trauma: Direct injury to the cervix or vagina during intercourse can lead to bleeding.
Do Not Miss Diagnoses
- Cervical Cancer: Although less common, it is crucial to rule out cervical cancer as a cause of post-coital bleeding. Early detection is key to effective treatment.
- Endometrial Cancer: Though more commonly associated with postmenopausal bleeding, it can also present with irregular vaginal bleeding, including post-coital bleeding in some cases.
Rare Diagnoses
- Vascular Malformations: Rare conditions such as arteriovenous malformations in the cervix can lead to significant bleeding after minimal trauma, such as intercourse.
- Blood Coagulation Disorders: Conditions affecting blood clotting, such as von Willebrand disease, can lead to excessive bleeding from minor injuries, including those sustained during intercourse.
- Pregnancy-Related Conditions: In early pregnancy, bleeding after intercourse can be a sign of a threatened abortion or an ectopic pregnancy, though these would typically be accompanied by other symptoms.
