BV or Thrush – Quick Answer

BV (Bacterial Vaginosis) → Caused by bacteria imbalance
Thrush (Yeast Infection) → Caused by fungal overgrowth (yeast)

Simple signs:

BV → Thin discharge + fishy smell
Thrush → Thick white discharge + itching

👉 They are not the same condition and require different treatments.

What Is BV (Bacterial Vaginosis)?

Bacterial vaginosis (BV) happens when the natural balance of bacteria in the vagina changes. Healthy vaginas have more “good” bacteria. When “bad” bacteria grow too much, BV can occur.

Key points about BV:

Not a sexually transmitted infection (STI)
More common in sexually active people
Caused by bacterial imbalance
Often mild but can lead to complications if untreated

Common Symptoms of BV

Thin, watery discharge
Grey or white discharge
Strong fishy smell (especially after sex)
Mild itching or irritation
Burning during urination (sometimes)

👉 Some people with BV have no symptoms.

What Is Thrush (Yeast Infection)?

Thrush, also called a yeast infection, is caused by an overgrowth of Candida yeast. Yeast naturally lives in the body, but when it grows too much, it causes infection.

Key points about thrush:

Caused by fungus (yeast)
Very common
Can happen at any age
Not usually sexually transmitted

Common Symptoms of Thrush

Thick, white discharge (like cottage cheese)
Intense itching
Redness and swelling
Pain during sex
Burning sensation when urinating

👉 Thrush usually does not have a strong smell.
