What is Recurrent Miscarriage?

Recurrent miscarriage refers to the occurrence of two or more consecutive pregnancy losses before the 28th week of gestation. While this condition is rare, its impact on a woman’s physical and emotional well-being can be profound.

1. Symptoms of Recurrent Miscarriage

  1. Repeated Vaginal Bleeding: Common in early pregnancy, often with or without clots.
  2. Recurrent Abdominal Pain: Persistent discomfort or pain in the lower abdomen or lower back.
  3. Fetal Development Stagnation: Abnormal or halted fetal development detected via ultrasound.
  4. Tissue Expulsion: The passage of fetal membranes or tissue during miscarriage.

2. Causes of Recurrent Miscarriage

  1. Anatomical Factors: Uterine abnormalities (such as a septate uterus or bicornuate uterus) can affect embryo implantation.
  2. Endocrine Factors: Conditions such as luteal phase defects or thyroid dysfunction may lead to miscarriage.
  3. Immune Factors: Abnormal immune responses may result in the rejection of the embryo.
  4. Infections: Infections like toxoplasmosis or cytomegalovirus can affect placental function.
  5. Lifestyle and Environmental Factors: Smoking, alcohol use, or exposure to harmful chemicals can increase miscarriage risk.
  6. Genetic Factors: Chromosomal abnormalities in the embryo are a common cause.

3. How to Diagnose Recurrent Miscarriage

Diagnosing recurrent miscarriage involves a comprehensive approach:

  1. Medical History: Collection of information regarding previous miscarriages and pregnancy history.
  2. Imaging Tests: Ultrasound to assess the uterus and embryo development.
  3. Endocrine Tests: Monitoring hormone levels, including progesterone and thyroid function.
  4. Immunological Tests: Screening for immune abnormalities, such as antiphospholipid antibodies.
  5. Genetic Testing: Chromosomal analysis for both partners to identify any genetic causes.

4. Treatment for Recurrent Miscarriage

Treatment depends on the underlying cause:

  1. Anatomical Factors: Surgery, such as hysteroscopic correction, may be needed for uterine abnormalities.
  2. Endocrine Treatment: Supplementing progesterone or correcting thyroid dysfunction can improve pregnancy conditions.
  3. Immunotherapy: Immunosuppressive treatment to address immune system-related issues.
  4. Infection Treatment: If infections are identified, antibiotics or antiviral medications are prescribed.
  5. Genetic Screening: Preimplantation genetic diagnosis (PGD) to select healthy embryos for IVF.
  6. Psychological Support: Counseling to help manage emotional stress and anxiety associated with multiple miscarriages.

5. Prevention of Recurrent Miscarriage

Preventive measures can significantly reduce the risk of recurrent miscarriage:

  1. Preconception Check-ups: Comprehensive health evaluations before pregnancy to detect potential risks.
  2. Healthy Lifestyle: Avoid smoking and alcohol, maintain a balanced diet, and engage in regular exercise to minimize environmental exposures.
  3. Regular Monitoring: Regular prenatal checkups to monitor hormone levels and ensure overall health during pregnancy.
  4. Professional Counseling: Genetic counseling and psychological support can prepare women physically and emotionally for a healthy pregnancy.

With scientific treatment and preventive measures, most women experiencing recurrent miscarriage can successfully conceive and carry a healthy baby to term.
