A "Fecal" Smell Down There? Why You Shouldn’t Ignore This Specific Vaginal Odor

A stool-like vaginal odor is not normal and should be evaluated, as causes range from external contamination or infections to a rectovaginal fistula, especially if gas or stool passes through the vagina. There are several factors to consider that affect urgency, what hygiene steps help versus harm, and when to seek medical care. See the details below for warning signs and the exact next steps that could impact your health and recovery.

A "Fecal" Smell Down There? Why You Shouldn't Ignore This Specific Vaginal Odor

Noticing a fecal or stool-like smell from the vagina can be upsetting, confusing, and embarrassing. You might wonder if it's a hygiene issue, an infection, or something more serious. While some vaginal odors are common and harmless, a fecal smell is not typical and deserves attention—without panic, but without ignoring it either.

This article explains what that odor may mean, when it could point to a condition like a rectovaginal fistula, and how pelvic health and hygiene play a role. The goal is to give you clear, calm information so you know what steps to take next.


What's Normal—and What's Not—When It Comes to Vaginal Odor

A healthy vagina has a mild scent that can change with:

  • Menstrual cycle
  • Sex
  • Exercise or sweating
  • Diet
  • Hormonal changes

Normal vaginal smells are often described as musky or slightly tangy. These are not cause for concern.

A fecal or sewage-like odor, however, is different. It suggests that something unusual is happening and should be evaluated by a medical professional.


Common Causes of a Fecal-Smelling Vaginal Odor

There are several possible explanations, ranging from relatively minor to more serious. Understanding them can help you decide when to seek care.

1. Hygiene-Related Issues

In some cases, the odor may come from external contamination, not the vagina itself.

Examples include:

  • Stool residue left after wiping
  • Difficulty cleaning after bowel movements
  • Wearing tight or non-breathable underwear
  • Excessive sweating around the vulva

Important note: Overwashing, douching, or using scented products can actually make things worse by disrupting the vagina's natural balance.

Good hygiene means:

  • Wiping front to back
  • Using mild, unscented soap on the external genital area only
  • Avoiding vaginal douches or deodorants
  • Changing underwear daily

If better hygiene resolves the smell within a short time, it was likely external.


2. Vaginal or Pelvic Infections

Certain infections can cause unusual or strong odors, sometimes mistaken for a fecal smell.

These include:

  • Bacterial vaginosis (BV) – often described as "fishy"
  • Severe or untreated infections
  • Infections involving both the vagina and nearby pelvic structures

Infections are usually accompanied by other symptoms, such as:

  • Abnormal discharge
  • Itching or burning
  • Pelvic discomfort
  • Pain during sex

These conditions are treatable, but they require medical diagnosis and proper treatment.


3. Rectovaginal Fistula (A Key Concern)

One of the most important conditions to rule out is a rectovaginal fistula.

What is a rectovaginal fistula?

A rectovaginal fistula is an abnormal connection between the rectum and the vagina. This opening allows stool or gas to pass from the rectum into the vagina, causing:

  • Fecal-smelling vaginal discharge
  • Passage of gas through the vagina
  • Recurrent vaginal infections
  • Ongoing irritation or discomfort

Why it happens

Rectovaginal fistulas can develop due to:

  • Childbirth complications (especially severe tearing)
  • Pelvic surgery
  • Inflammatory bowel disease (such as Crohn's disease)
  • Pelvic radiation
  • Severe infections or trauma

This condition is not caused by poor hygiene, and it is not something you can fix at home.


Why Ignoring This Odor Can Be Risky

Ignoring a persistent fecal smell can lead to:

  • Chronic infections
  • Worsening pelvic health
  • Skin irritation and pain
  • Emotional distress and sexual discomfort
  • Delayed diagnosis of a serious condition

While it's important not to panic, it's equally important not to assume the problem will go away on its own.


Pelvic Health: Why It Matters Here

Your pelvic region contains organs that work closely together, including the bladder, rectum, uterus, and vagina. When something affects one part, others may be involved.

Good pelvic health means:

  • Strong, well-functioning pelvic floor muscles
  • Healthy tissue and blood flow
  • No abnormal connections or chronic inflammation

Conditions like rectovaginal fistulas disrupt pelvic health and often require coordinated care from gynecologists, colorectal specialists, or pelvic health experts.


When to Speak to a Doctor (This Is Important)

You should speak to a doctor promptly if you notice:

  • A persistent fecal or sewage-like vaginal odor
  • Stool or gas passing through the vagina
  • Ongoing discharge that smells unusual
  • Pelvic pain or pressure
  • Recurrent vaginal infections
  • Symptoms after childbirth or pelvic surgery

Some causes can be serious or life-threatening if left untreated, especially if infection spreads. Getting medical advice early often leads to better outcomes and simpler treatments.


What to Expect at a Medical Visit

A healthcare provider may:

  • Ask about your symptoms and medical history
  • Perform a pelvic exam
  • Order imaging tests or lab work
  • Refer you to a specialist if needed

These steps are routine and focused on helping you feel better—not judging you.


Supporting Overall Health (Yes, Even Beyond Pelvic Issues)

Sometimes, concerns about intimate health raise broader questions about the body. Many people find it helpful to use symptom checkers for reassurance or guidance on related health issues. For example, conditions affecting pelvic blood flow and vascular health can sometimes manifest in multiple ways—if you or your partner have concerns about sexual health, Ubie offers a free Erectile Dysfunction symptom checker that can help identify potential causes and next steps. Understanding the full picture of pelvic and vascular wellness matters for everyone.


Key Takeaways

  • A fecal-smelling vaginal odor is not normal and should not be ignored.
  • Causes range from hygiene-related issues to infections and rectovaginal fistula.
  • Good hygiene supports vaginal and pelvic health but cannot fix structural problems.
  • Rectovaginal fistulas are medical conditions that require professional care.
  • Avoid douching or scented products, which can worsen symptoms.
  • Speak to a doctor about any persistent, severe, or unusual symptoms—especially if they could be serious or life-threatening.

Final Word

Your body has ways of signaling when something isn't right. A fecal vaginal odor is one of those signals. Addressing it early protects your pelvic health, prevents complications, and helps you regain comfort and confidence. You're not overreacting by seeking care—you're taking responsible steps for your health.
