1. Bacterial Vaginosis (BV)
Bacterial Vaginosis is the most common vaginal infection in women of reproductive age.
Symptoms:

-
New sexual partners
-
Hormonal changes
Treatment:

Usually treated with antibiotics prescribed by a doctor

Avoid douching and use mild, unscented hygiene products
2. Yeast Infections
Yeast infections are caused by an overgrowth of Candida, a type of fungus naturally present in the vagina.
Symptoms:

Strong, musty or bread-like odor

Thick, white, cottage-cheese-like discharge

Itching and redness
Why It Happens:

3. Poor Hygiene or Sweat Accumulation
Even healthy vaginas produce discharge and sweat, which can lead to temporary odor.
Causes:

Tips:

Wear cotton underwear and breathable clothing

Wash with warm water and mild, unscented soap

Change sanitary pads, tampons, or panty liners frequently

Additional Signs:

Unusual discharge (color or consistency change)

Action:
