How long can endometritis go undetected?

Endometritis is a condition that involves inflammation of the inner lining of the uterus, known as the endometrium. It is often caused by an infection after childbirth, abortion, miscarriage or gynecological procedures. Endometritis can sometimes develop without any obvious cause as well. This condition can lead to several complications if left untreated, so detecting it early is important.

What is Endometritis?

Endometritis refers to inflammation of the endometrium, which is the inner lining of the uterus. This lining grows and sheds each month during the menstrual cycle. When bacteria infiltrate the uterus after childbirth or a medical procedure, it can cause the endometrial tissue to become inflamed and infected.

The most common causes of endometritis include:

  • Childbirth – After a vaginal delivery, the cervix remains open which allows bacteria to enter and infect the uterine lining. This is known as postpartum endometritis.
  • Miscarriage or abortion – Instrumentation of the uterus can introduce bacteria leading to infection.
  • Gynecologic procedures – Hysteroscopy, dilation and curettage (D&C), endometrial biopsy or insertion of an intrauterine device (IUD) can expose the uterus to bacteria.
  • Pelvic infections – Sexually transmitted diseases like chlamydia and gonorrhea can ascend into the uterus.
  • Foreign objects – Retained tampons, diaphragms or uterine implants can increase infection risk.

Less common causes include cancer, intrauterine adhesions (Asherman’s syndrome), and unknown or idiopathic factors. Women with a weakened immune system are also at higher risk of developing endometritis.

Signs and Symptoms

The signs and symptoms of endometritis may include:

  • Pelvic pain
  • Low grade fever
  • Abnormal vaginal discharge – This may be brown, yellow or green in color with a foul odor.
  • Pain or bleeding during sexual intercourse
  • Painful urination
  • General feeling of illness
  • Abdominal tenderness

However, some women with endometritis may not experience any symptoms at all. This is known as “silent endometritis” and can still lead to complications if left untreated.

How is Endometritis Diagnosed?

If endometritis is suspected, your doctor will perform a pelvic exam to check for tenderness or abnormalities in the uterus. They may also use some of the following tests to confirm diagnosis:

  • Endometrial biopsy – A small sample of the uterine lining is taken and analyzed under a microscope for signs of inflammation.
  • Endometrial culture – A sterile swab is used to collect a tissue sample that is cultured to identify any infection-causing bacteria present.
  • Saline infusion sonography – Saline is infused into the uterus through a catheter and ultrasound is performed to check for abnormalities in the endometrial lining.
  • Hysteroscopy – A lighted instrument called a hysteroscope is inserted into the vagina and cervix to directly examine the inside of the uterus.

Your doctor may also test for sexually transmitted infections through urine tests or cervical cultures. Blood tests can check for signs of infection as well.

How Long Can Endometritis Go Undetected?

Endometritis can potentially go undetected for an extended period of time in some women who do not display any overt symptoms. Here are some general timeframes:

  • Postpartum endometritis after childbirth is usually detected within the first 1-2 weeks after delivery.
  • Endometritis from miscarriage or abortion may be detected within 1-4 weeks.
  • Endometritis after gynecologic procedures can be diagnosed within 1-4 weeks.
  • Chronic endometritis without a recognized cause can go undetected for months or even years.
  • Recurrent or intermittent endometritis may come and go over several months.

However, every woman’s experience can vary. Some factors that can allow endometritis to go unnoticed longer include:

  • No symptoms – Silent or asymptomatic endometritis has no red flag symptoms.
  • Mild symptoms – Symptoms may be dismissed or attributed to other causes.
  • No recent risk factors – Endometritis arising without a known cause may not be suspected.
  • Negative initial testing – Endometrial cultures or biopsies can sometimes return false negatives.
  • Failure to follow up – Lack of follow-up testing after procedures or childbirth.

Complications of Untreated Endometritis

Leaving endometritis undiagnosed and untreated can lead to complications like:

  • Chronic infection – Endometritis can become a chronic condition with longer-lasting inflammation and pain.
  • Infertility – The inflammation can damage the endometrium and impair implantation or conception.
  • Abortion or miscarriage – Existing endometritis can trigger pregnancy loss.
  • Abscesses – Infected fluid pockets may form inside the uterus or fallopian tubes.
  • Adhesions – Inflamed areas can scar and bind together inside the uterus or fallopian tubes.
  • Sepsis – Bacteria from advanced endometritis can enter the bloodstream and lead to life-threatening illness.

That’s why timely diagnosis and treatment of endometritis is essential. The risk of complications rises the longer endometritis goes undetected. Silent or mild cases can still lead to damage even without significant symptoms.

Who is at Risk of Endometritis Going Undetected?

Certain women have a higher risk of endometritis going undiagnosed longer:

  • Women with asymptomatic disease or very mild symptoms
  • Women who do not follow up properly after childbirth, miscarriage, abortion or uterine procedures
  • Women with weakened immune systems or chronic illnesses
  • Women using IUD contraception (risk of infection over time)
  • Women with infertility or recurrent miscarriages
  • Women who neglect annual well-woman exams

Doctors may also have a higher index of suspicion in women with recurrent gynecologic infections or pelvic inflammatory disease in their history. Having multiple sexual partners or STIs also raise the risk of endometrial infection going unnoticed.

When to See a Doctor

You should consult a doctor promptly if you experience any potential symptoms of endometritis, especially after childbirth or uterine procedures. Report any of the following:

  • Fever over 100.4°F
  • Foul-smelling lochia or vaginal discharge
  • Pelvic pain
  • Bleeding between periods
  • Pain or irritation from an IUD
  • Abdominal pain or tenderness

Also make sure to follow up after any miscarriage, abortion, childbirth, or gynecologic procedure. Alert your doctor if you do not recover as expected. Get evaluated if you have any infertility concerns or experience recurrent miscarriages as well.

How is Endometritis Treated?

Treating endometritis involves antibiotics to fight the uterine infection along with possible additional therapies:

  • Antibiotics – Oral or intravenous antibiotics are used to treat the bacteria causing endometritis. Antibiotic choice depends on the source of infection.
  • D&C procedure – Removal of uterine contents by dilation and curettage may be necessary.
  • Hysteroscopy – Direct visualization inside the uterus with specialized tools can help remove debris or adhesions.
  • Estrogen therapy – Estrogen creams or supplements can help heal the endometrial lining in some cases.
  • Removal of foreign objects – Retrieval of any retained tampons, IUDs, implants, etc.

Your doctor will tailor the treatment plan based on your particular case. You should notice an improvement in symptoms within a few days on antibiotics. However, follow up is very important to confirm the infection has fully resolved.

Preventing Endometritis

You can reduce your risk of developing endometritis by:

  • Practicing safe sex and protecting against STIs
  • Ensuring proper hygiene with tampon use
  • Promptly treating any vaginal infections
  • Following all pre-op and post-op directions with gynecologic procedures
  • Attending all postpartum follow up visits after giving birth
  • Having any retained IUDs or implants promptly removed
  • Quitting smoking to avoid damaging the endometrial lining
  • Maintaining proper blood sugar control if diabetic

In some women, suppressive antibiotics may be recommended around the time of gynecologic procedures or childbirth if they have a history of endometritis. Proper preventive care can help minimize your infection risk.

Key Points

  • Endometritis is inflammation and infection of the endometrium or uterine lining.
  • It is often caused by childbirth, miscarriage, abortion or uterine procedures but can arise without known cause.
  • Symptoms include pelvic pain, discharge, bleeding and fever but it can also be asymptomatic.
  • It is diagnosed through endometrial biopsy, cultures, sonography or hysteroscopy.
  • Endometritis may go undetected for weeks or even months if symptoms are very mild.
  • Missing the diagnosis can lead to complications like infertility, miscarriage or chronic pelvic infection.
  • Treatment involves promptly administering antibiotics and sometimes additional surgical procedures or estrogen therapy.
  • Prevention focuses on minimizing exposure to infections, prompt treatment of other pelvic infections, and proper follow up care after procedures.

The Bottom Line

Endometritis can potentially go undiagnosed for weeks or months before overt symptoms appear. Some cases may resolve spontaneously, but a delay in treatment raises the risk of complications. That’s why it is essential to have a high index of suspicion and pursue proper diagnostic testing at the earliest signs of a problem. Catching endometritis early is crucial to prevent lasting repercussions like infertility or chronic infection. If you have any concerns about unexplained postpartum symptoms, pain or abnormal bleeding, do not hesitate to see a doctor and get evaluated further.
