Physiologic discharge: This is the most common cause of vaginal discharge without an odor. It's a normal, clear or white discharge that occurs throughout the menstrual cycle due to the body's natural cleansing process.

Yeast infection (Candidiasis): Although typically associated with an odor, some cases may present without a noticeable smell. It's characterized by a thick, white, cottage cheese-like discharge.
Bacterial vaginosis (BV): While BV often has a fishy odor, some cases can be odorless. It's associated with an imbalance of vaginal bacteria.
Trichomoniasis: This sexually transmitted infection can cause a thin, greenish or yellowish discharge without a strong odor in some cases.

Gonorrhea: A sexually transmitted infection that can cause discharge without a distinct odor. It's crucial to diagnose and treat to prevent complications like pelvic inflammatory disease.
Chlamydia: Another sexually transmitted infection that may present with discharge and no odor. Like gonorrhea, it requires prompt diagnosis and treatment to avoid long-term reproductive health issues.
Cervical cancer: Although rare, cervical cancer can cause abnormal vaginal discharge without an odor. Regular screening is key to early detection.

Foreign body: The presence of a foreign object in the vagina, such as a forgotten tampon, can cause discharge without an odor, depending on the duration it has been in place.
Vaginal tuberculosis: A rare condition that can cause vaginal discharge among other symptoms. It's more common in areas where tuberculosis is prevalent.
Desquamative inflammatory vaginitis (DIV): A rare condition characterized by a purulent vaginal discharge, which may not always have an odor. It's associated with inflammation of the vaginal walls.
