A strong or “fishy” odor from the genital area—especially in women—is usually a sign of an imbalance or infection, not normal hygiene.

Here’s what you should know about this

A “fishy” smell is most often associated with:

1. Bacterial Vaginosis (BV)

Most common cause of a fishy vaginal odor.

Happens when there’s an overgrowth of certain bacteria in the vagina.

Symptoms: Thin gray/white discharge, strong odor (especially after s3x), itching or burning.

Needs antibiotics, not just home remedies.

2. Trichomoniasis

A sexually transmitted infection (STI) caused by a parasite.

Can cause a fishy smell, green/yellow discharge, itching, and discomfort.

Treated with prescription medication.

3. Poor hygiene or trapped sweat

Sweat, tight clothing, or infrequent washing can trap bacteria and moisture.

While not always a “fishy” smell, it can cause an unpleasant odor.

4. Menstruation or leftover tampons

A forgotten tampon can cause a very strong, rotten smell, which may be mistaken for fishy.
