Endometritis

Introduction

Endometritis is an inflammatory condition affecting the lining of the uterus (endometrium), often triggered by infection after childbirth, gynecological procedures, or sexually transmitted bacteria. It can cause pelvic pain, fever, abnormal bleeding or discharge, and might even lead to fertility issues if left untreated. Although not extremely common, endometritis impacts daily life by causing discomfort, fatigue, or anxiety over reproductive health. In this article we’ll explore symptoms of endometritis, common causes, diagnostic steps, treatment options, outlook, and realistic tips to manage or reduce risks.

Definition and Classification

Endometritis is clinically defined as inflammation and infection of the uterine endometrium. Broadly it’s classified into:

• Acute endometritis – rapid onset, fever and purulent discharge, often post-partum or post-procedure.
• Chronic endometritis – low-grade inflammation, subtle symptoms, may follow PID (pelvic inflammatory disease) or chronic IUD irritation.

Affected systems: primarily the female reproductive tract, specifically the endometrial tissue lining the uterine cavity. Subtypes may be further grouped by etiology, for example:

• Infectious endometritis: bacterial (Staphylococcus, Streptococcus, Neisseria gonorrhoeae, Chlamydia trachomatis), Mycoplasma spp.
• Non-infectious endometritis: less common, can be autoimmune or associated with retained products of conception.

This classification helps guide treatment and predicts potential complications, like adhesions (Asherman’s syndrome) or chronic pelvic pain.

Causes and Risk Factors

Acute or chronic endometritis results when the uterine lining becomes colonized by pathogens or irritated by foreign material. Known causes include:

• Postpartum infection: most common, especially after cesarean section or prolonged labor, when bacteria from the vagina ascend into the uterus.
• Gynecological procedures: dilation and curettage (D&C), endometrial biopsy, insertion/removal of IUDs can introduce bacteria if sterile technique isn’t perfect or if vaginal flora are imbalanced.
• Sexually transmitted infections (STIs): chlamydia and gonorrhea often spread upward causing PID that includes endometritis.
• Retained products of conception: after miscarriage or delivery, leftover tissue can perpetuate inflammation and bacterial growth.
• Intrauterine devices (IUDs): though low overall risk, especially non-hormonal copper IUDs can slightly raise local infection risk in first few weeks post-insertion.

Risk factors can be modifiable or non-modifiable. Non-modifiable include recent childbirth or genetic predisposition to weaker immune responses. Modifiable factors include:

• Poor peripartum hygiene
• Unsafe sexual practices
• Lack of timely removal of retained placental fragments

Contributing lifestyle or environmental factors: smoking, obesity, underlying diabetes or immunosuppression may dampen defenses. In many cases, the exact trigger isn’t fully clear (idiopathic endometritis), reminding clinicians to maintain broad suspicion when patients present with pelvic discomfort and unexplained fever.

Pathophysiology (Mechanisms of Disease)

Normally, the uterine endometrium has a self-limited inflammatory cycle each month, regulated by estrogen and progesterone. In endometritis this balance is disrupted:

• Bacterial invasion through the cervix or hematogenous spread activates innate immune cells (neutrophils, macrophages).
• Cytokines like IL-6, TNF-alpha are released, increasing vascular permeability and recruiting more inflammatory cells.
• Endothelial swelling and tissue edema results in pain and impaired microcirculation.
• Persistent infection leads to chronic changes: plasma cell infiltration (a diagnostic marker), stromal fibrosis, scarring of the endometrium which can contribute to menstrual irregularities or adhesion formation.

In acute cases, the endometrial glands and stroma show neutrophilic infiltration under microscopy. Chronic endometritis is hallmarked by plasma cells among lymphocytes, indicating a longer-term immune response. Untreated, this cascade may extend beyond the uterus, causing salpingitis (fallopian tube inflammation) or pelvic abscess.

Symptoms and Clinical Presentation

Endometritis symptoms vary widely between individuals. Many women experience:

• Pelvic pain: often dull and constant, may feel like menstrual cramps but out of cycle.
• Fever and chills: more typical in acute cases, occasionally high-grade (≥38°C).
• Abnormal uterine bleeding: spotting, intermenstrual bleeding, heavier or prolonged menses.
• Purulent or foul-smelling vaginal discharge: yellowish, greenish, sometimes blood-tinged.
• Dyspareunia: pain during intercourse.

Early vs advanced manifestations:

• Early: mild pelvic discomfort, slight spotting, low-grade fever. Symptoms may be mistaken for menstrual or urinary infections.
• Advanced: severe pelvic pain, high fever, nausea, malaise, possible systemic signs like tachycardia.

Chronic endometritis often has subtler clues: infertility, recurrent miscarriage, intermittent spotting, but without overt fever. Individuals differ: some tolerate discomfort until it worsens, others seek care quickly. Warning signs requiring urgent attention include severe abdominal pain, persistent bleeding, high fever, or signs of sepsis (rapid heartbeat, low blood pressure). Never use this as a self-diagnosis checklist, always see a provider for formal evaluation.

Diagnosis and Medical Evaluation

Diagnosing endometritis combines history, physical exam, lab tests, and imaging. Typical pathway:

• Clinical history: ask about recent deliveries, procedures, symptoms timeline.
• Physical exam: pelvic exam may reveal uterine tenderness, cervical motion tenderness, abnormal discharge.
• Laboratory tests: CBC (elevated WBC count), CRP or ESR (markers of inflammation), endometrial cultures to identify pathogens.
• Ultrasound: transvaginal ultrasound to rule out retained products of conception or abscess formation.
• Endometrial biopsy: definitive for chronic endometritis by identifying plasma cells in the stroma.

Differential diagnosis includes pelvic inflammatory disease affecting tubes/ovaries, retained products post-miscarriage, appendicitis (atypical pain), or hemorrhagic ovarian cysts. Occasionally laparoscopy is used to directly visualize pelvic organs or drain abscesses. A thorough diagnostic approach reduces misdiagnosis and helps tailor antibiotic therapy.

Which Doctor Should You See for Endometritis?

If you suspect endometritis, the first stop is usually an obstetrician-gynecologist (OB-GYN). Family physicians or primary care doctors can start evaluation and blood tests, but for targeted gynecological care you’d ask “which doctor to see” the answer is a gynecologist. If symptoms are severe high fever, intense pelvic pain, heavy bleeding you may need urgent or emergency care in a hospital.

Telemedicine visits are great for initial guidance: discussing symptoms, interpreting lab results, or getting second opinions when traveling or in remote areas. Online consultations can’t replace a pelvic exam or urgent imaging, but they help clarify questions you didn’t think to ask in-person visits. Ultimately, telehealth and in-person care complement each other without replacing physical evaluation when necessary.

Treatment Options and Management

Evidence-based treatment for endometritis focuses on eradicating infection and reducing inflammation:

• Antibiotics – first-line regimens often include a broad-spectrum combination: clindamycin plus gentamicin, or doxycycline with metronidazole for coverage of anaerobes and typical STI pathogens.
• Removal of foreign bodies – retained placental fragments or IUDs should be removed if identified.
• Hospitalization – for severe cases needing IV antibiotics, fluid management, or surgical drainage of abscesses.
• Pain control – NSAIDs (ibuprofen) or acetaminophen to relieve discomfort.
• Follow-up – repeat cultures or ultrasound to confirm resolution, especially in chronic cases.

Advanced therapies: if standard antibiotics fail or complications like pelvic abscess develop, options include laparoscopic drainage, hysteroscopic removal of adhesions, or hysterectomy in rare, refractory cases. Side effects of meds (GI upset, yeast infections) should be discussed.

Prognosis and Possible Complications

With timely treatment, most acute endometritis cases resolve within a couple of weeks. Chronic endometritis can take longer months to fully clear. Prognosis factors:

• Severity at presentation (high fever, abscesses)
• Timeliness of antibiotic therapy
• Presence of retained tissue
• Underlying immune status

Possible complications if untreated:

• Asherman’s syndrome (intrauterine adhesions), leading to menstrual abnormalities and infertility.
• Pelvic abscess formation requiring drainage.
• Infertility or recurrent pregnancy loss.
• Sepsis rare but life-threatening if infection spreads beyond reproductive tract.

Close follow-up reduces long-term risks and preserves fertility.

Prevention and Risk Reduction

While not all cases of endometritis are preventable, steps to reduce risk include:

• Strict sterile technique during delivery and gynecological procedures.
• Timely removal of IUDs if infection suspected.
• Safe sexual practices: condom use, regular STI screening, prompt treatment of chlamydia or gonorrhea.
• Postpartum care: good perineal hygiene, monitoring for fever or unusual discharge.
• Prompt evacuation of retained products after miscarriage or delivery.

Screening for STIs in high-risk groups helps intercept ascending infections. Educating patients about warning signs persistent fever, pelvic pain encourages early medical attention. Vaccines (e.g., HPV) reduce some infection risks but don’t directly prevent endometritis. Ultimately combining procedure protocols and lifestyle measures lowers overall incidence.

Myths and Realities

Many misconceptions surround endometritis. Let’s clear up a few:

• Myth: “Only childbirth causes endometritis.” Reality: While postpartum infection is common, procedures like D&C or STIs play a major role.
• Myth: “IUDs always lead to womb infection.” Reality: Risk is slightly raised in the first few weeks, but modern IUDs are safe long-term when placed properly.
• Myth: “Chronic pelvic pain means you have endometritis.” Reality: Pain can stem from many pelvic issues fibroids, endometriosis, IBS so biopsy and cultures are needed for diagnosis.
• Myth: “Antibiotics fix everything.” Reality: Correct antibiotic choice, removal of any retained tissue, and follow-up are crucial. Inadequate therapy can lead to recurrence.
• Myth: “You must have surgery.” Reality: Most cases respond to medication alone unless abscess or adhesions form.

Sorting fact from fiction reduces undue fear and leads to better outcomes.

Conclusion

Endometritis, an infection or inflammation of the uterine lining, can range from mild pelvic discomfort to severe systemic illness. Recognizing symptoms like pelvic pain, fever, or abnormal bleeding and seeking timely medical evaluation are key. Diagnosis relies on clinical history, pelvic exam, lab tests, ultrasound, and sometimes biopsy. Treatment centers on targeted antibiotics, removal of any retained tissue, and close follow-up. Preventive measures sterile techniques for procedures, safe sex, postpartum hygiene—help reduce risk. Fertility is often preserved if managed appropriately. Always consult qualified healthcare professionals for personalized guidance and never ignore warning signs of serious complications.
