Unusual Odor: What a “Fishy Smell” Really Means and When to See a Doctor

4. Menstruation or Forgotten Tampons
During menstruation, blood can sometimes alter natural vaginal odor. More concerning, however, is the risk of a forgotten tampon. When left inside, a tampon can cause a very strong, rotten-like smell that some women mistake for fishy odor.

If you suspect this, it’s important to remove the tampon promptly. If you’re unable to, seek immediate medical help, as retained tampons can cause serious infections.

When to See a Doctor
For older women, especially after menopause, it’s important not to dismiss vaginal changes as “just part of aging.” A strong odor may be your body’s way of signaling that something isn’t right.

You should consult a doctor if:

The odor is persistent, strong, or worsening
There is unusual discharge (gray, green, or yellow in color)
You experience itching, burning, or pain
You suspect a sexually transmitted infection
You believe you may have left a tampon or menstrual product in place
Seeking help early can prevent complications and bring peace of mind. Most conditions causing vaginal odor are very treatable with the right care.

Preventing Vaginal Odor and Supporting Vaginal Health
Good feminine hygiene practices can go a long way toward maintaining comfort and confidence. Doctors recommend a few simple steps:

Gentle Hygiene
Wash only the external genital area with warm water and mild, unscented soap.
Never douche. Douching disrupts the natural balance of bacteria and often makes problems worse.
Avoid perfumed sprays, wipes, or powders, which can irritate sensitive skin.
Breathable Clothing
Choose cotton underwear or moisture-wicking fabrics that allow airflow.
Change out of sweaty or damp clothes promptly after exercise or hot weather.
Safe Sexual Practices
Use protection to reduce the risk of sexually transmitted infections.
Ensure both partners are tested regularly if in new or multiple relationships.
