For many women in midlife and beyond, body changes can raise sensitive health concerns. One common but often unspoken issue is a fishy vaginal odor. While unsettling, doctors stress it’s usually a sign of imbalance or infection rather than poor hygiene — and most causes are treatable.
The most frequent culprit is bacterial vaginosis (BV), caused by an overgrowth of certain bacteria. BV produces a thin gray discharge and a strong odor, especially after sex, and requires antibiotics. Another possibility is trichomoniasis, a sexually transmitted infection that causes fishy odor, colored discharge, and irritation. It must be treated with prescription medication.
Sometimes, odor stems from non-infectious causes, such as sweat trapped in tight clothing or a forgotten tampon, which can create a strong, rotten smell. Hormonal changes after menopause may also increase vulnerability to infections.
Doctors recommend gentle hygiene (no douching), breathable cotton underwear, and safe sexual practices. Persistent odor, unusual discharge, or discomfort should prompt medical care.
The good news: nearly all causes of vaginal odor can be identified and effectively treated, restoring both comfort and confidence.
