Repeated miscarriage

Repeated miscarriage, also known as recurrent pregnancy loss (RPL), is defined as having two or more consecutive miscarriages. This condition can be deeply distressing and may lead to concerns about future pregnancies. Understanding the potential causes and exploring treatment options is essential for those affected.

Possible Causes of Repeated Miscarriage:

  1. Genetic Factors:
    • Chromosomal Abnormalities: In about 2-5% of cases, one or both partners may have a chromosomal abnormality that leads to recurrent miscarriages.
  2. Anatomical Issues:
    • Uterine Abnormalities: Structural problems with the uterus, such as a septum, fibroids, or scarring, can interfere with pregnancy.
  3. Hormonal and Endocrine Factors:
    • Progesterone Deficiency: Low levels of progesterone, which supports the uterine lining, can lead to miscarriage.
    • Thyroid Disorders: Both hyperthyroidism and hypothyroidism can increase the risk of miscarriage.
    • Polycystic Ovary Syndrome (PCOS): Women with PCOS may have a higher risk due to hormonal imbalances.
  4. Immunological Factors:
    • Antiphospholipid Syndrome (APS): This autoimmune disorder can cause blood clots and lead to miscarriage.
    • Other Immune System Disorders: Some immune conditions might lead to the body attacking the pregnancy.
  5. Infections:
    • Certain infections, although rare, can lead to miscarriage, especially if they are not treated promptly.
  6. Lifestyle Factors:
    • Smoking, Alcohol, and Drug Use: These increase the risk of miscarriage.
    • Obesity: Being significantly overweight can contribute to miscarriage risk.
    • Environmental Exposures: Certain toxins or excessive stress can play a role.
  7. Blood Clotting Disorders:
    • Conditions like thrombophilia can increase the likelihood of blood clots forming in the placenta, leading to miscarriage.

Diagnosis and Testing:

  • Genetic Testing: Karyotyping of both partners can identify chromosomal issues.
  • Ultrasound: To check for uterine abnormalities.
  • Hormonal Testing: To assess levels of key hormones like progesterone and thyroid hormones.
  • Blood Tests: To check for autoimmune disorders or clotting issues.

Treatment Options:

  1. Medical Management:
    • Progesterone Supplementation: Can be given to support the uterine lining.
    • Thyroid Medication: To manage thyroid-related issues.
    • Blood Thinners: Like low-dose aspirin or heparin for clotting disorders.
    • Immunotherapy: In certain immune-related miscarriages.
  2. Surgical Treatment:
    • Correction of Uterine Abnormalities: Surgery may be recommended to correct anatomical issues.
  3. Lifestyle Changes:
    • Healthy Weight: Achieving a healthy weight through diet and exercise.
    • Avoiding Harmful Substances: Quitting smoking, reducing alcohol, and avoiding illicit drugs.
  4. Support and Counseling:
    • Emotional support, counseling, and sometimes couples therapy are crucial to cope with the stress and grief associated with repeated miscarriages.

When to See a Specialist:

  • After two or more consecutive miscarriages.
  • If you’re over 35, as age can increase the risk.
  • If you have a known risk factor (e.g., PCOS, thyroid issues).

Prognosis:

While repeated miscarriage is challenging, many women with RPL go on to have successful pregnancies, especially with proper diagnosis and treatment. Each case is unique, so individualized care is critical.
