Possible Causes of Fishy Vaginal Odor

Having a fishy vaginal odor can be uncomfortable and concerning. This is often noticeable because of vaginal discharge or as a result of a bacterial infection. The most common cause of this fishy odor is vaginitis, or a vaginal infection or inflammation.

The smell of the vagina varies throughout the menstrual cycle. However, if you are experiencing redness, burning, or itching sensation, or any unusual vaginal discharge, you should visit your OB-GYN.

Read on to learn all about fishy vaginal odor and how it can be prevented.

What causes fishy vaginal odor?

A UTI can cause foul or strong-smelling urine along with burning sensation, itchiness, or pain. A UTI can be one of the reasons behind fishy vaginal odor.

Vaginitis

Vaginitis is an infection of the vagina, commonly caused by a 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

Trichomoniasis, a sexually transmitted infection that is spread via sexual contact due to a parasite. This parasite gives rise to a foul or fishy vaginal odor.

This condition can cause a foul vaginal discharge that can be green, grey, or yellow in colour. According to the Mayo Clinic, it can cause genital pain, itchiness, redness, and burning while urinating or having sex.

Therefore, whenever you are experiencing any vaginal issue, contact your doctor immediately.

Cervical or vaginal cancer

Sometimes the foul smell or fish vaginal odor can be a symptom of cervical or vaginal cancer.

Visit the OB-GYN immediately to detect any underlying health condition that causes the fishy vaginal odor.

Bacterial Vaginosis

Bacterial vaginosis is a bacterium imbalance or 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.

Ways to get rid of fishy vaginal odor

Adopt good vaginal hygiene if your vagina smells like a fish

  • Apply a mild, fragrance-free soap gently only on your vulva.
  • Wash your underwear with good quality and unscented washing powder.
  • Wash your vulva properly with water if you experience a foul or fishy vaginal odor.
  • Use fresh underwear daily and in case of excess sweating, change your underwear.
  • Use a soft washcloth to wipe down the genital area properly while taking a shower.
  • Take a shower whenever you feel excess sweat build-up. Sweat can change your vaginal odor.

Use internal menstrual products, if you’re comfortable with it

During periods, some women may notice a stronger vaginal smell. Hormonal changes can be one of the reasons to cause a smell similar to ammonia or iron. Some internal menstrual products can trap the smell, compounding the effects.

Sometimes vaginal fluid interacts with semen, causing the vaginal odor. Also, some lubricants can affect vaginal pH, affecting the smell of vagina.

  • Avoid scented or flavored lubricants
  • Use a condom to prevent contact between vaginal fluids and semen
  • Wash your vulva with water

Consume probiotics to help improve fishy vaginal odor

Probiotics are healthy bacteria beneficial for the overall body, including vaginal health. Consuming probiotics can help prevent some vaginal infections. Also, it can reduce the risk of abnormal vaginal odor as it restores the vagina’s normal pH.

Use probiotics like sauerkraut, kombucha, miso, kimchi, tempeh, kefir, and yogurt to enhance your vaginal health along with overall health. Also, these probiotics keep your urinary tract healthy and infection-free.
