It’s normal for the vagina to have a mild, natural scent—but a strong or unpleasant odor can sometimes signal that something’s off. Here are four common reasons:
1. Bacterial imbalance (Bacterial Vaginosis)
The most common cause of a “fishy” smell is Bacterial Vaginosis. It happens when the natural balance of good and bad bacteria in the vagina is disrupted. This can be triggered by things like douching, new sexual partners, or even hormonal changes.
2. Poor hygiene or sweat buildup
The external genital area (vulva) can trap sweat, urine residue, or discharge, especially in hot climates or after exercise. If not cleaned gently and regularly, this can lead to odor.
3. Forgotten tampon or foreign object
A tampon left in too long can cause a very strong, foul smell and may lead to infection. This is important to address quickly if suspected.
4. Sexually transmitted infections (STIs)
Certain infections like Trichomoniasis can cause a noticeable odor along with symptoms like unusual discharge, itching, or irritation.
When to see a doctor:
If the smell is strong, persistent, or comes with symptoms like itching, burning, unusual discharge (gray, green, or frothy), or pain, it’s best to get checked by a healthcare provider.
Quick tips:
- Avoid douching (it disrupts natural balance)
- Wear breathable cotton underwear
- Change tampons/pads regularly
- Practice safe sex
