Infection After Endometrial Biopsy: Signs, Symptoms, and When to Seek Care

Last updated: June 30, 2026

Overview

In an endometrial biopsy, the healthcare provider removes a small piece of the uterine lining for examination. Through this process, the doctor can check for abnormalities, such as polyps, hyperplasia, or cancerous cells. Generally, an endometrial biopsy is quite safe and minimally invasive. This may pose a risk of infections and other post-procedural complications.

Thus, before undergoing an endometrial biopsy, women need to be aware of the signs of infection that may appear after the procedure to ensure their safety and enable timely medical intervention. This article will focus on the physical signs that can indicate an infection and how you can avoid it.

What Is An Endometrial Biopsy?

Healthcare providers use a procedure known as an endometrial biopsy to look for abnormalities in the female reproductive system. The process generally takes 15-20 minutes and is minimally invasive. After doctors retrieve a small tissue sample from the lining of your uterus, they examine it under a microscope for any anomalies.

An endometrial biopsy might be necessary for you if you suffer from irregular menstrual cycles, if there is a thickening of the lining of the uterus, or if you continue to bleed after menopause. The procedure might also be recommended to you if you have abnormal bleeding because of hormonal treatment or irregular cells found during a Pap smear.

What Are The Primary Signs Of Infection After Endometrial Biopsy?

During regular recovery, most patients develop mild to moderate pain, which feels like menstrual cramping within 24 to 48 hours after the procedure. Spotting or dark discharge is common in such instances. Nevertheless, if you suffer from post-biopsy infection, you will need to pay attention to the following symptoms:

  • Bad-smelling discharge: While discharge is normal, it becomes more pronounced when you suffer from a post-biopsy infection. Infection-related discharge is typically yellow, green, or white discharge with a foul or fishy smell, which signifies overactive growth of bacteria or inflammation of the uterus.
  • Pain: The body responds well to OTC medications, and pain decreases over time. If, however, pain becomes sharp, localized to one area of the body, and intensifies after several days, something might be going wrong.
  • Prolonged bleeding: If you have to change your pad frequently and you bleed excessively, passing blood clots larger than a quarter, you might be having complications.

Normal Recovery vs. Potential Infection

How does one distinguish between normal post-biopsy recovery and a potential infection? You can use the following table to compare typical side effects:

Symptom

Normal Recovery

Signs of Potential Infection

Abdominal pain

Mild or moderate cramping/ Pain improves with medication

Sharp, stabbing pain/Tender to the touch

Body temperature

Normal range (below 100.4°F (38°C)

Fever of 100.4°F (38°C) or higher/ Recurring chills

Vaginal bleeding

Light spotting or brownish discharge for a few days

Heavy bleeding, running quickly through pads/Large clots

Discharge odour

No odour or a slightly metallic scent from blood

Strong, foul, or fishy odour

Discharge colour

Pink, red, or dark brown

Yellow, green, or thick white

Duration

Symptoms gradually improve

Symptoms intensify after 3-7 days

What Are the Systemic Symptoms of a Post-Biopsy Infection?

At times, a local infection may trigger an immune response. Here are the warning signs that you should look out for:

  • Fever: Any temperature greater than 100.4°F is generally the reason for an infection occurring in the body.
  • Rigours and Chills: These are the first warning signs of a fever coming on.
  • Malaise: This involves general weakness and fatigue.

Can the Infection Worsen?

One must know how to accurately distinguish between normal post-biopsy recovery and a potential infection.

For better understanding: 

  • Endometriosis: Here, the tissue resembling the lining of the uterus starts growing inside other organs, such as those located at the back of your uterus, pelvic tissues surrounding the uterus, ovaries, the peritoneum, and fallopian tubes. In some very rare cases, endometriosis can even occur in your rectum, bladder, intestine, vagina, lungs, and many other areas.
  • Salpingitis: Salpingitis is a bacterial infection found in one or both of the fallopian tubes. The most common causes of the condition include sexually transmitted diseases (STIs) such as chlamydia and gonorrhea. 
  • Tubo-ovarian abscess: This is a complication of pelvic inflammatory disease. It is a severe, pus-filled inflammatory mass which involves the fallopian tubes and ovaries. It can be life-threatening if it ruptures. 
  • Peritonitis: This occurs when the membrane lining the stomach, called the peritoneum, becomes inflamed due to bacterial or fungal infection. Peritonitis is fatal, and timely treatment is necessary.
  • Sepsis: Sepsis refers to the medical state caused by dysfunction of the body's response to infection, leading to tissue injury and ultimately organ failure.

It is evident that each stage represents a medical condition that becomes increasingly dangerous compared to the preceding one. Pelvic inflammatory disease, if severe or persistent, may result in the scarring of the fallopian tubes, which can then bring about such complications as infertility, ectopic pregnancy, and pelvic pain.

This is the reason why it is crucial to address the infection-related symptoms promptly.

How Can You Prevent Infection During Recovery?

After an endometrial biopsy, you may experience some cramps and vaginal spotting, and these symptoms should subside within just a few days. But the healing process is sensitive, and you need to do your best to take every possible step to keep yourself safe from infections.

It is highly recommended that you stay away from:

  • Sexual intercourse: Abstain from sexual intercourse for at least a week or till the bleeding stops.
  • Tampons: Do not insert tampons in your vagina when you are bleeding. It is usually not advised to use menstrual cups either.
  • Swimming or baths:During recovery, stick to showers to prevent water from entering your vaginal canal. 
  • Douching:Douching should be avoided generally as well. However, after your endometrial biopsy, it is strictly prohibited to engage in the activity, as external bacteria could be pushed into the reproductive tract.

Make sure to discuss the dos and don’ts with your healthcare provider for safe and effective recovery.

When to Contact Your Healthcare Provider

Infections can worsen, and it is necessary to know when to seek help from a medical professional. Sometimes, women may delay contacting their healthcare provider because they believe the warning signs are simply a part of the healing process. That could not be further from the truth. Visit a doctor immediately if you notice even one of the following signs:

  • Any increase in body temperature beyond 38°C (100.4°F) after the procedure
  • Worsening of pelvic or abdominal pain within the initial 48 hours
  • Strange vaginal discharge that appears in colour (either greenish or yellow) or smells bad
  • Heavy bleeding, which becomes worse a couple of days after light bleeding
  • Nausea or vomiting along with pelvic pain

Going to the ER would be necessary in cases where there is:

  • Body temperature rises to over 102.2°F (39°C) with chills and shivers
  • Sudden, sharp, or worsening abdominal/pelvic pain
  • Feeling faint, confused, or overall unwell for a long time
  • Signs of sepsis include rapid heart rate, difficulty breathing, extreme fatigue, or an altered mental state.

Remember that if the symptoms are improving each day, it likely means that recovery is going well. However, if the symptoms do not improve or worsen after 48 hours, it is better to contact a healthcare provider. Early detection will lead to earlier treatment, which is easier and quicker, and will prevent the infection from developing into a more serious form.

How Is the Infection Treated?

If you develop an infection after your endometrial biopsy, panicking is not the solution. Once you visit a healthcare provider, they will help you determine the best course of action to achieve complete recovery. Now, the treatment of an infection largely depends on the severity of the symptoms.

  • Oral antibiotics will be prescribed for approximately 2 weeks in cases of mild to moderate infection.
  • For moderate-to-severe PID or when an abscess is suspected, intravenous antibiotics are necessary.
  • In cases of tubo-ovarian abscess, surgical intervention may be the best course of action, along with antibiotic administration.
  • Sepsis requires immediate hospitalization as the condition can be life-threatening if not treated on time.

It is important that you complete the full course of antibiotics prescribed by your healthcare provider, even if your symptoms resolve more quickly than expected. This is to ensure that the risk of relapse and antibiotic resistance is avoided.

Conclusion

While an endometrial biopsy is generally a safe procedure, the risk of infection is always involved. Knowing the distinction between signs of normal healing and those of infection may play a vital role in how your health turns out after this procedure. There are many symptoms that may occur after an endometrial biopsy, and some of the common ones include the presence of a foul odour from the vagina, pain, fevers, and excess bleeding, which should not be ignored, as they may suggest something wrong that must be sorted out by a healthcare professional.

Taking the relevant steps to care for your body after the process, such as avoiding activities that put you at risk of bacterial infections, will definitely help with recovery. Most of the issues can definitely be sorted out before they become complicated if action is taken early enough.
