Vaginitis is an infection of the vagina, commonly caused by bacterial infection. But, it can also be the result of a sexually transmitted infection (STI) called trichomoniasis or a yeast infection.
A fishy smell can be due to vaginitis. Consult your doctor or an OB-GYN to treat this vaginal infection.
Trichomoniasis, a sexually transmitted infection that is spread via sexual contact due to a parasite. This may be avoided by using a condom or being in a monogamous relationship. This parasite gives rise to a foul or fishy vaginal odor.
This condition can cause a foul vaginal discharge that can be green, gray, or yellow in color. According to the Mayo Clinic, it can cause genital pain, vaginal spotting, itchiness, redness, and burning while urinating or having sex.

Cervical or vaginal cancer
Sometimes the foul smell or fish vaginal odor can be a symptom of cervical or vaginal cancer.
Aside from vaginal bleeding or spotting during sexual contact, it may present with watery, light pink or copious gray to dark brown vaginal discharge. It has a peculiar fishy smell. It is advisable to have an annual Pap test to check if there are any problems in the cervix.
Visit the OB-GYN immediately to detect any underlying health condition that causes the fishy vaginal odor.
Bacterial Vaginosis
Bacterial vaginosis is a common condition brought about by bacterial overgrowth in the vagina. Usually, penile-vaginal intercourse with a new partner is the cause of this condition. Also, women who are not sexually active can also get bacterial vaginosis.
This is because the usual bacteria causing the infection are normally found in the vagina and surrounding areas. It becomes problematic when there is an imbalance of bacterial growth.
Hormonal changes like in menopause, stress, and pregnancy can also result in bacterial vaginosis.
