Signs of Infection After Hysteroscopy: Symptoms You Should Not Ignore

What is Hysteroscopy?

A hysteroscopy is a procedure that allows doctors to examine the inside of the uterus using a thin instrument called a hysteroscope.

The hysteroscope is gently passed through the vagina and cervix to reach the uterus, allowing the doctor to view the uterine lining without making surgical cuts. The procedure may be used to diagnose or treat conditions such as:

• Abnormal uterine bleeding
• Uterine polyps
• Fibroids
• Adhesions inside the uterus
• Recurrent miscarriage investigation

Some hysteroscopies are diagnostic, used only to examine the uterus, while others are operative, where small instruments remove polyps or treat certain abnormalities.

Is Infection Common After Hysteroscopy?

Infection after hysteroscopy is uncommon but possible. Studies suggest the risk ranges from about 0.01% to 1.42% of cases, making it a relatively rare complication.

Because the procedure is performed under sterile conditions, the chance of bacteria entering the uterus is generally low. In most cases, antibiotics are not routinely required.

Even though infection is rare, it is important to recognise the warning signs. Early detection of symptoms allows doctors to treat the infection quickly and prevent further complications.

What Are the Normal Symptoms After Hysteroscopy?

It is common to experience mild symptoms for a few days after the procedure. These usually improve on their own as your body heals. Typical recovery symptoms may include:

• Light vaginal bleeding or spotting
• Mild cramping or period-like pain
• Watery discharge
• Slight fatigue

Light bleeding may continue for a few days and sometimes up to a week. If these symptoms remain mild and gradually improve, they are generally considered part of normal recovery. Symptoms that worsen or persist could indicate an infection.

Possible Warning Signs of Infection After a Hysteroscopy Procedure

Most people recover from a hysteroscopy without complications. Some light bleeding, mild cramps or slight discomfort for a day or two is normal.

However, certain symptoms may indicate that the body is not healing as expected. Being aware of these signs of infection can help you recognise when to contact a doctor.

Symptoms that should not be ignored:

• Fever or High Temperature: A fever may be an early sign of infection. If your temperature rises above 38°C, or you develop chills and body aches along with a fever, consult a healthcare professional. Persistent fever could indicate infection in the uterus or surrounding tissues.
• Persistent or Worsening Abdominal Pain: Mild cramping is expected. Pain becomes concerning when it worsens instead of improving, lasts longer than expected or does not respond to pain relief. Increasing pelvic or abdominal pain may indicate inflammation or infection.
• Foul-Smelling Vaginal Discharge: Light discharge is normal, but a strong, unpleasant smell, unusual colour (yellow or green) or thick consistency may indicate infection.
• Heavy or Prolonged Bleeding: Light spotting is common. Bleeding that is heavy, lasts many days or contains large clots should be checked by a doctor.
• Feeling Generally Unwell: Infection may start subtly with fatigue, chills, nausea, dizziness or weakness, especially when combined with other warning signs.
• Severe Lower Back or Pelvic Pain: Pain spreading beyond the lower abdomen into the back or deeper pelvis may signal inflammation affecting nearby organs. Sharp, persistent or worsening pain requires medical advice.

How Soon Can an Infection Develop After Hysteroscopy?

An infection can develop within a few days after the procedure, though timing may vary.

Many post-procedure infections appear within the first week following hysteroscopy. In some cases, symptoms may develop slightly later, depending on the type of bacteria involved.

Early symptoms may include:

• Increased vaginal discharge
• Pelvic discomfort
• Low-grade fever

If symptoms worsen instead of improving, do not ignore them. Prompt medical evaluation can help determine whether the symptoms are part of normal healing or indicate an infection.

Causes of Infection After Hysteroscopy

Infections after hysteroscopy usually occur when bacteria enter the uterus during or after the procedure. Although hysteroscopy is performed under sterile conditions, the vagina naturally contains bacteria that can occasionally move upward into the uterus.

Factors that can contribute to infection include:

• Instrument insertion through the cervix
• Tissue irritation or minor trauma during the procedure
• Fluid used to slightly expand the uterine cavity
• Pre-existing vaginal infections

Most post-hysteroscopy infections involve inflammation of the uterine lining, known as endometritis.

Higher Risk Groups for Infection After Hysteroscopy

Although infections are rare, some individuals may have a higher risk. Possible risk factors include:

• Previous pelvic inflammatory disease (PID)
• Existing vaginal infections
• Multiple prior uterine procedures
• Longer or more complex hysteroscopic surgery
• Removal of adhesions or extensive uterine tissue

Some studies also suggest infections may be slightly more likely in procedures involving larger surgical interventions inside the uterus.

Diagnosis of Infections After Hysteroscopy

Doctors usually diagnose infections based on a combination of symptoms and medical evaluation.

Your doctor may perform:

• A pelvic examination
• Blood tests to detect infection markers
• Vaginal or cervical swabs
• Ultrasound to assess the uterus

These tests help determine the type of infection and guide the most appropriate treatment.

What Treatments Are Used for Post-Hysteroscopy Infections?

Most infections after hysteroscopy are successfully treated with medication.

Treatment may include:

• Antibiotics: The most common treatment, used to eliminate bacterial infection and prevent complications.
• Pain Management: Pain relief medications may be recommended to reduce discomfort during recovery.
• Monitoring Symptoms: Your doctor may schedule follow-up appointments to ensure the infection has cleared.

In rare cases where the infection is severe, hospital treatment may be necessary, though this is uncommon.

How Can You Reduce the Risk of Infection After Hysteroscopy?

Simple aftercare steps can help lower the risk of infection during recovery. Doctors commonly recommend the following as part of infection after hysteroscopy treatment:

• Use sanitary pads instead of tampons until bleeding stops.
• Avoid swimming or baths for a short period.
• Maintain good personal hygiene.
• Follow all post-procedure instructions carefully.

Recovery Outlook After Treatment

Most signs of infection after hysteroscopy improve with proper treatment.

When detected early, doctors usually prescribe antibiotics and symptoms often begin to ease within a few days. Serious complications are uncommon when treatment starts promptly.

Many people can return to normal daily activities once symptoms improve. It is important to complete the full course of medication and follow all advice from your doctor.

Monitoring your symptoms and seeking medical help if they worsen can support a smooth and complete recovery.

Conclusion

Hysteroscopy is generally a safe, minimally invasive procedure used to diagnose or treat various uterine conditions. For most people, recovery is straightforward, with only mild symptoms such as light bleeding or gentle cramping for a short period.

It is important to recognise the signs of infection after hysteroscopy. Symptoms like fever, foul-smelling discharge, severe abdominal pain or heavy bleeding should not be ignored. Early detection allows doctors to treat any issues promptly and reduce the risk of complications.

Following your doctor’s aftercare advice and listening to your body can support a smooth recovery. If any symptom seems unusual or worsens, contacting a healthcare professional is the safest step.
