Asherman Syndrome: Causes, Symptoms, Treatment

Written by Medicover Team and Medically Reviewed by Dr Vineela Medapati , Gynecologists

Asherman syndrome is a condition that affects a woman's uterus, menstrual cycles and fertility. It happens when scar tissue, called adhesions, forms inside the uterus. These adhesions can partially or completely block the uterine cavity, making it harder for normal menstrual flow, conception or pregnancy to occur. While not very common, Asherman syndrome is often underdiagnosed because its symptoms can look like other gynaecological problems.

Understanding this condition is important for women who have had uterine procedures, repeated miscarriages or unusual menstrual patterns.

What Are the Signs and Symptoms of Asherman's Syndrome?

Symptoms of Asherman syndrome can vary widely. Some women may have mild symptoms, while others face serious reproductive challenges.

Common signs and symptoms include:

• Women may experience very light periods (hypomenorrhea) or no periods at all (amenorrhea) due to blocked menstrual flow.
• Trapped blood inside the uterus can cause severe cramps or pelvic discomfort.
• Adhesions may prevent sperm from reaching the egg or make it harder for an embryo to attach to the uterine lining.
• Some women experience repeated miscarriages because scar tissue interferes with implantation or reduces blood supply to the uterus.

Note: Sometimes, women with mild adhesions may have no obvious symptoms, making it important to monitor menstrual patterns and reproductive health after uterine procedures.

What Are the Asherman Syndrome Causes?

The main cause of Asherman syndrome is trauma to the uterine lining (endometrium). This usually happens after surgery, infection, or other medical procedures. When the endometrium heals improperly, scar tissue forms instead of normal tissue.

• Dilation and Curettage (D&C): Dilation and Curettage (D&C) is the most common cause of Asherman syndrome, often after miscarriage, abortion or childbirth. Repeated or aggressive D&C can injure the uterine lining.
• Uterine Surgery: Surgeries like myomectomy (fibroid removal), cesarean section or other uterine operations may cause scarring.
• Infections: Severe infections such as pelvic inflammatory disease (PID) or tuberculosis can damage the endometrium.
• Radiation or Trauma: Rarely, pelvic radiation therapy or long-term use of certain intrauterine devices (IUDs) can contribute to scar formation.

When to See a Doctor?

You should consult a gynecologist or an Asherman syndrome specialist if you experience:

• Absence or significant reduction in menstrual flow after a uterine procedure.
• Recurrent miscarriages or difficulty conceiving for over a year.
• Pelvic pain related to blocked menstrual flow.
• History of repeated D&C procedures with abnormal cycle patterns.

How is Asherman's Syndrome Diagnosed?

Diagnosis involves a combination of medical history, physical examination, imaging and hysteroscopy. Accurate identification of adhesions is essential to plan effective treatment.

• Clinical Evaluation: Doctors review past surgeries, infections, or reproductive issues and perform a pelvic exam to assess uterine health before ordering further tests.
• HSG: Hysterosalpingography uses contrast dye and X-rays to reveal filling defects, irregular shapes or partial blockage of the uterine cavity.
• Sonohysterography: Saline infusion sonography expands the uterine cavity with saline, helping ultrasound detect adhesions and cavity distortion.
• Transvaginal Ultrasound: This imaging test can show a thin or irregular endometrium and scar tissue, though it is less sensitive than other methods.
• MRI: MRI is rarely needed but in complex cases it highlights fibrous bands as hypointense areas on T2 images, aiding in precise evaluation.
• Hysteroscopy (Gold Standard): A thin camera is inserted into the uterus for direct visualization of adhesions. It confirms diagnosis and allows immediate treatment.

Thus, Asherman syndrome radiology is a critical step in identifying intrauterine adhesions, but hysteroscopy remains the definitive method.

What is the Asherman Syndrome Treatment?

Asherman syndrome treatment focuses on removing intrauterine adhesions and restoring fertility. Options range from hysteroscopic surgery to hormonal therapy, with follow-up care and fertility support tailored to the woman's reproductive goals.

Hysteroscopic Adhesiolysis

A minimally invasive surgery where intrauterine adhesions are cut under direct vision. This helps restore the normal uterine cavity and improves fertility potential.

• Adhesions are removed using tiny surgical instruments.
• The cavity regains its natural shape and function.

Post-Surgery Measures

After surgery, certain steps are taken to prevent the uterus from forming new adhesions and to encourage healing.

• Insertion of an intrauterine balloon or catheter to keep cavity open.
• Estrogen therapy helps regenerate healthy endometrial tissue.

Fertility Support

For women struggling to conceive naturally after surgery, fertility treatments may be advised depending on uterine recovery.

• Assisted reproductive technologies (ART) such as IVF can be considered.
• Helps women achieve pregnancy when natural conception is difficult.

Follow-Up

Monitoring after treatment ensures the uterus stays healthy and open for normal function.

• Repeat hysteroscopy or imaging may be needed.
• Ensures the cavity remains clear of adhesions.

What Are the Complications of Asherman's Syndrome?

If left untreated, Asherman syndrome can cause serious reproductive and overall health challenges. Adhesions in the uterus may affect fertility, pregnancy and menstrual cycles, while also leading to emotional distress and long-term complications for women's well-being.

• Infertility: Intrauterine adhesions reduce the healthy uterine lining, limiting implantation space and lowering the chances of achieving or maintaining pregnancy.
• Recurrent Miscarriages: Even after conception, scarred areas may have poor blood supply, increasing the risk of repeated miscarriages and pregnancy loss.
• Menstrual Disorders: Women may suffer from long-term irregular cycles, very light periods or complete absence of menstruation due to blocked blood flow.
• Asherman Syndrome Pregnancy Risks: Pregnancies carry higher risks, including placenta accreta, preterm labor, growth restrictions or even stillbirth.
• Emotional and Psychological Impact: Infertility and pregnancy loss often cause emotional strain, anxiety, depression and stress that affect mental health.

Natural Remedies for Asherman's Syndrome

While medical treatment is essential, some natural measures can support healing and improve uterine health. These should complement, not replace, professional care.

• Balanced Diet: Foods rich in vitamin E, C and antioxidants support tissue healing.
• Herbal Supplements: Some herbs like turmeric, ginger and ashwagandha may reduce inflammation (use only after medical consultation).
• Yoga and Exercise: Improves blood circulation to pelvic organs, reducing stiffness and promoting healing.
• Stress Management: Meditation, acupuncture or relaxation techniques may help with emotional well-being.

Conclusion

Asherman syndrome requires timely diagnosis and expert care to prevent long-term reproductive complications. Early evaluation and personalized treatment can help restore uterine function and support overall reproductive health. Professional guidance ensures safe recovery and better outcomes for women planning to conceive.
