Do Fibroids Cause Odor? When to Be Concerned

Fibroids rarely cause a vaginal odor on their own, even though they often change how much you bleed and how much discharge you have.1Atlanta Fibroid Center®. Smelly Discharge: Uterine Fibroids or Infection? When a new smell shows up, the cause is usually something that sits alongside the fibroids, most often a common and treatable infection. In a small number of cases, though, a fibroid that is breaking down can be the source, which is why a new smell deserves a check rather than a guess.

What Fibroids Do to Discharge and Periods

Fibroids are noncancerous growths that can sit in the lining of the uterus, inside the muscle wall, or on the outer surface.2Atlanta Fibroid Center®. Smelly Discharge: Uterine Fibroids or Infection? Their most common effect is heavier-than-normal periods.3UChicago Medicine. Don’t suffer in silence: Get answers about uterine fibroid symptoms and treatment They can also increase the amount of vaginal discharge, but that discharge is typically not smelly.4Atlanta Fibroid Center®. Smelly Discharge: Uterine Fibroids or Infection?

Fibroid-related discharge is usually watery or slightly thicker, clear to white, and has little or no smell. It may increase around your period or when fibroids are larger. Old blood can tint it brown without meaning anything is wrong. A change from your usual pattern matters more than the amount itself.

Where a fibroid sits changes what you notice. Fibroids that bulge into the uterine cavity tend to cause the heaviest and longest periods, while fibroids on the outside surface often cause pressure or bloating with little change in bleeding.

Fibroids don’t cause vaginal infections directly.5UChicago Medicine. Don’t suffer in silence: Get answers about uterine fibroid symptoms and treatment Heavy bleeding can set the stage for one, though. Frequent or abnormal bleeding can upset the vagina’s normal acidity and self-cleaning, making infections more likely.6Frontiers in Cellular and Infection Microbiology. Vaginal microbial ecology in abnormal uterine bleeding: compositional alterations and pathophysiological impact as early predictors of secondary infection Blood is less acidic than a healthy vagina, so long stretches of bleeding raise the pH, and odor-causing bacteria grow as protective bacteria struggle. Wearing pads daily, or using douches, sprays, powders or washes, may also raise the risk of BV and yeast infections.7UChicago Medicine.

It helps to know what counts as heavy. Bleeding that soaks through a pad or tampon every hour or two, or that includes clots larger than a coin, is worth mentioning to a doctor. Heavy bleeding can lead to iron deficiency, so tiredness, breathlessness or dizziness alongside heavy periods is a reason to ask for a blood test.

The Usual Culprits Behind a New Smell

A new fishy or unpleasant smell can signal an infection or another condition, and it shouldn’t be put down to fibroids without an exam.8Scratch. Do Fibroids Cause Discharge? Watery Discharge, Tissue and Odor Bacterial vaginosis (BV), a common vaginal infection, and fibroids are separate problems that can happen at the same time, and treating one won’t fix the other.

The common infections look and smell a little differently. BV often causes a thin grey-white discharge with a fishy smell that may be stronger after sex. Yeast infections usually cause itching and thick white discharge with little smell. Trichomoniasis, a sexually transmitted infection, can cause frothy yellow-green discharge with a strong odor. These overlap enough that only a swab can confirm which one you have.

BV is an imbalance, not a hygiene problem: protective bacteria drop in number and other bacteria overgrow. It isn’t classed as a sexually transmitted infection, though sex can trigger it or make it flare. It often returns after treatment, so a repeat episode doesn’t mean you did anything wrong, but it is worth telling your doctor.

Some habits make odor worse. Douching and scented washes strip away protective bacteria, and the smell often comes back afterward. Rinsing the outside with plain water is enough. On heavy days, change pads often and choose breathable cotton underwear.

Pelvic inflammatory disease, an infection of the womb, tubes or ovaries, can cause discharge that looks, smells or feels unusual for you.9nhs.uk. Pelvic inflammatory disease It can also bring lower tummy or pelvic pain, deep pain during sex, and bleeding between periods or after sex.10nhs.uk. Pelvic inflammatory disease Some of those symptoms, like heavy or painful periods, overlap with fibroids, so it’s easy to blame the wrong cause.11nhs.uk. Pelvic inflammatory disease Pain during sex or bleeding after sex alongside a new smell is a reason to get tested for infection.

A rarer cause is worth ruling out. Cervical cancer can produce foul-smelling discharge when parts of the tumor lose their oxygen supply and die, and that discharge can contain bits of tissue.12Moffitt Cancer Center. Cervical Cancer Signs and Symptoms This kind of odor is usually a sign of advanced disease, not an early one.13Nusantics. Beware of Abnormal Vaginal Discharge: Signs of Cervical Cancer! Staying up to date with cervical screening is the best protection, and a persistent foul smell is a reason to be examined.

When a Fibroid Itself Can Cause a Foul Smell

As fibroids grow, they can outgrow their blood supply and start to break down.14Journal of Obstetric and Gynaecological Practices POGS. A Rare Case Reports of Giant Degenerated Cervical Fibroid Polyp Fibroids near or on the cervix that break down have caused foul-smelling discharge in reported cases.15Journal of Obstetric and Gynaecological Practices POGS. A Rare Case Reports of Giant Degenerated Cervical Fibroid Polyp In one such case, the discharge came with bleeding between periods.16Journal of Obstetric and Gynaecological Practices POGS. A Rare Case Reports of Giant Degenerated Cervical Fibroid Polyp

Dead fibroid tissue is a good place for bacteria to grow, especially near the cervix and vagina, where bacteria are plentiful. Once bacteria take hold, the tissue gives off the strong, rotten odor people often describe.

The classic cause is a fibroid that slips through the cervix. Some fibroids grow on a stalk from the inside of the uterus and can be pushed down through the cervix into the vagina.17Discover Medicine. Management of an infected prolapsed pedunculated submucosal leiomyoma in a postmenopausal woman: a case report This is a rare complication.18Discover Medicine. Management of an infected prolapsed pedunculated submucosal leiomyoma in a postmenopausal woman: a case report The thin stalk struggles to feed the fibroid, so the tissue often dies and can become infected.19PubMed Central.

Not every fibroid can do this. Prolapse happens with fibroids growing from the inner lining of the uterus on a stalk, not with those buried in the muscle wall or on the outside. The uterus squeezes, as it does during a period, and that pushing can gradually move the fibroid toward the cervix. Symptoms sometimes get worse during periods, when cramping and bleeding increase.

Symptoms can include a feeling of a lump in the vagina, foul-smelling discharge, bleeding and lower belly pain.20Discover Medicine. Management of an infected prolapsed pedunculated submucosal leiomyoma in a postmenopausal woman: a case report In some women the fleshy mass can be seen or felt at the vaginal opening.21Pan African Medical Journal. Prolapsed submucosal uterine fibroid (fibroid polyp) It can happen after menopause, not only in younger women.22Discover Medicine. Management of an infected prolapsed pedunculated submucosal leiomyoma in a postmenopausal woman: a case report Because this can be mistaken for a prolapsed bladder, describe exactly what you feel.

Doctors typically remove the fibroid through the vagina by cutting its stalk. Antibiotics are often given if the tissue is infected. Once the fibroid is removed, the smell usually clears. Don’t try to push the lump back yourself.

Smelly Discharge After Fibroid Treatment

Uterine fibroid embolization (UFE, sometimes written UAE) blocks the fibroid’s blood supply so it shrinks.23PubMed Central. Microspheres vaginal discharge as a complication after Uterine Artery Embolization for intramural/submucosal fibroid Ongoing vaginal discharge afterward is very common, especially with fibroids that bulge into the uterine lining.24PubMed Central. Microspheres vaginal discharge as a complication after Uterine Artery Embolization for intramural/submucosal fibroid The dying fibroid can drain or shed tissue through the uterus.25PubMed Central. Microspheres vaginal discharge as a complication after Uterine Artery Embolization for intramural/submucosal fibroid This discharge is usually described as clear, odorless and sticky.26PubMed Central. Microspheres vaginal discharge as a complication after Uterine Artery Embolization for intramural/submucosal fibroid

Mild cramping, tiredness and a low fever in the first few days are a normal recovery reaction.27Inciteful Med. When Severe Uterine Fibroid Pain or Fever Is an Emergency: Warning Signs A foul smell is different. Infection of the uterus after embolization has been reported in up to 1 in 200 women.28Stanford Health Care. Infection That’s uncommon, but real enough to watch for. It usually comes from bacteria reaching a fibroid that is shedding, and it typically shows up as fever and pain that keeps getting worse.29Stanford Health Care. Infection IV antibiotics may cure it, but sometimes surgery to remove the fibroid or the uterus is needed.30Stanford Health Care. Infection

Worrying signs are a fever that rises or returns, chills, or pain that gets worse instead of better. So is discharge that turns smelly, or tissue passing for days beyond what you were told to expect.

Infection can appear days or even weeks after the procedure, so a new smell later on still counts. Discharge may continue for weeks, but it shouldn’t turn from clear to foul.

If you do call your treatment team, have the date of your procedure and when the smell started. Know your highest temperature and whether you’ve had chills, and be ready to say how much discharge or tissue you are passing.

Warning Signs That Need Prompt Care

An infected fibroid can form a pocket of pus inside it.37Inciteful Med. When Severe Uterine Fibroid Pain or Fever Is an Emergency: Warning Signs Because that infection can spread or burst, it can lead to septic shock, with dangerously low blood pressure and organ failure.38Inciteful Med. When Severe Uterine Fibroid Pain or Fever Is an Emergency: Warning Signs High fever, chills and a foul smell together mean same-day care or the emergency department, not waiting for a routine appointment.

A mild new smell without fever or pain can wait for a routine visit within a week or two. Feeling faint, very unwell or confused with a fever is an emergency.

An isolated smell is most often BV or another treatable infection, which is uncomfortable but not dangerous in the short term. Even so, it shouldn’t be left for months, because untreated infections can sometimes move upward and cause pelvic infection.

What to Expect at the Doctor

A provider should evaluate any vaginal odor or ongoing discharge.39UChicago Medicine. Don’t suffer in silence: Get answers about uterine fibroid symptoms and treatment A swab of the discharge can show signs of infection such as a higher pH and extra white blood cells.40Frontiers in Cellular and Infection Microbiology. Vaginal microbial ecology in abnormal uterine bleeding: compositional alterations and pathophysiological impact as early predictors of secondary infection A pelvic exam can show whether a fibroid has slipped into the cervix or vagina, and an ultrasound shows the size and position of fibroids.

To prepare, note when the smell started, what it’s like, and whether it’s worse after periods or sex. List any recent fibroid procedure or new sexual partner. Avoid douching for a day or two beforehand so the swab is accurate. Mention any vaginal lump, bleeding between periods, or pain.

The doctor usually asks about your symptoms first, including your periods, sexual history and any recent procedures, because the history points toward the likely cause. A speculum exam then lets them see the discharge and the cervix directly, which is how a fibroid sitting at the cervix would be spotted. It takes a few minutes. A hand exam may follow to feel the size of the uterus and check for tenderness, which can suggest pelvic infection. You may be offered a cervical screening test if you’re due.

The swab is quick, and some results are ready the same day. It can often identify BV, yeast and trichomoniasis, and your doctor may also test for chlamydia and gonorrhea, since they can cause similar symptoms. If the swab shows no infection but the smell continues, the doctor will look for another source such as a fibroid or retained object. An ultrasound is usually painless and can be done over the belly or with a thin probe in the vagina for a clearer view.

Treatment depends on the cause. BV and trichomoniasis are treated with antibiotics, yeast with antifungals, and partners may need treatment for some infections. If heavy fibroid bleeding keeps triggering infections, ask about treating the bleeding itself.

Odor, Intimacy and Confidence

Fibroids can cause bloating and a larger belly that leave some women feeling uncomfortable or unattractive.41USA Fibroid Centers. Let’s Talk About Fibroids And Sex About 1 in 5 women in one national survey said fibroids hurt their sense of femininity and body image.42USA Fibroid Centers. Let’s Talk About Fibroids And Sex

Getting a smell diagnosed and treated is usually the fastest way to stop worrying about it. BV can flare after sex, so mention that pattern to your doctor. Telling a partner what’s going on often eases tension more than avoiding sex. Painful sex is worth raising too, since infection and fibroids can both be treated.

If bringing it up feels embarrassing, remember that doctors hear about vaginal odor often. Saying “I’ve noticed a new smell for two weeks” is enough. Writing your concerns down beforehand helps if you tend to feel flustered, and you can ask for a longer appointment or a female clinician if that would put you more at ease.
