Differential Diagnosis for Green Vaginal Discharge
Single Most Likely Diagnosis
- Bacterial Vaginosis (BV): This condition is characterized by an imbalance in the normal vaginal flora, leading to an overgrowth of bacteria. It is the most common cause of abnormal vaginal discharge in women of reproductive age, and the discharge is often thin and greenish or yellowish in color, with a fishy odor.
Other Likely Diagnoses
- Trichomoniasis: A sexually transmitted infection caused by the parasite Trichomonas vaginalis. It can cause a green, frothy, and foul-smelling vaginal discharge.
- Gonorrhea: A sexually transmitted infection caused by Neisseria gonorrhoeae, which can lead to a greenish or yellowish vaginal discharge.
- Chlamydia: Another sexually transmitted infection, caused by Chlamydia trachomatis, which may result in a greenish or mucopurulent vaginal discharge.
Do Not Miss Diagnoses
- Pelvic Inflammatory Disease (PID): An infection of the female reproductive organs that can cause a range of symptoms, including abnormal vaginal discharge. PID is a serious condition that requires prompt treatment to prevent long-term complications such as infertility and chronic pelvic pain.
- Cervical Cancer: Although less common, cervical cancer can cause abnormal vaginal discharge, including green discharge. Early detection is crucial for effective treatment.
Rare Diagnoses
- Foreign Body: The presence of a foreign object in the vagina, such as a forgotten tampon, can cause a green, foul-smelling discharge.
- Vaginal Tumors: Rare tumors of the vagina can cause abnormal vaginal discharge, including green discharge.
- Genital Ulcers: Certain conditions like genital herpes or syphilis can cause ulcers that may lead to abnormal discharge, though this is less commonly green in color.
