There are several reasons why a woman’s underwear might have an unpleasant odor. Some of the most common causes include:
1. Natural Body Secretions
-
-
- Sweat: The groin area has sweat glands, and when sweat mixes with bacteria, it can cause odor.
- Vaginal Discharge: A mild scent is normal, but strong or fishy smells may indicate an infection.
- Menstrual Blood: Blood has a metallic scent, and prolonged exposure to underwear can cause odor.
-
2. Poor Hygiene
-
-
- Not changing underwear frequently or wearing tight, non-breathable fabrics can trap moisture and bacteria, leading to bad smells.
-
3. Infections
-
-
- Bacterial Vaginosis (BV): Causes a fishy odor due to an imbalance of vaginal bacteria.
- Yeast Infection: Usually produces a musty or bread-like odor, along with itching and discharge.
- Sexually Transmitted Infections (STIs): Some STIs, like trichomoniasis, can cause foul-smelling discharge.
-
4. Diet and Medications
-
-
- Certain foods (like garlic, onions, or asparagus) and medications can alter body odors, including vaginal scent.
-
5. Leftover Urine or Fecal Residue
-
-
- Incomplete wiping or urinary incontinence can lead to odor on underwear.

How to Prevent and Manage Odor
-
-
- Wear breathable, cotton underwear.
- Change underwear daily and after sweating.
- Practice good hygiene and wipe properly after using the restroom.
- Avoid douching, as it disrupts vaginal pH.
- Stay hydrated and eat a balanced diet.
- Seek medical attention if the odor is strong, persistent, or accompanied by unusual discharge or irritation.

If you’re noticing a consistent or unusual odor, it might be worth consulting a healthcare professional to rule out any underlying conditions.
