Recurrent Pregnancy Loss

Patients often experience discouragement following consecutive miscarriages, but with proper clinical guidance from an experienced specialist, healthy pregnancy outcomes can be supported. Early diagnosis and structured prenatal care serve as key factors in achieving a successful conception.

Types of Recurrent Miscarriage

Recurrent miscarriages are classified into two categories based on the timing and stage of pregnancy loss.

Recurrent Early Pregnancy Loss

Recurrent early miscarriages typically occur within the first trimester or prior to the 13th week of pregnancy. Chromosomal anomalies and numerical patterns frequently play a primary role in such losses. Impaired embryonic growth and development are also observed in the majority of early pregnancy losses.

Recurrent Late Pregnancy Loss

Any pregnancy loss occurring between the 13th and 20th week of gestation is classified as a late miscarriage. Specific anatomical factors and cervical insufficiency can contribute to pregnancy loss. The incidence of late miscarriage is elevated among patients of advanced maternal age and those with a history of recurrent losses.

Identifying and managing underlying etiological factors enables effective clinical management of both types of recurrent miscarriages.

Symptoms

Symptoms of recurrent miscarriages vary among individuals. Common clinical signs experienced by patients include vaginal bleeding and pelvic pain, though some instances may present with minimal or no symptoms. Additional signs of recurrent pregnancy loss include:

• Sudden Decrease in Pregnancy Symptoms
• Absence of Fetal Cardiac Activity / Movements
• Vaginal Spotting
• Passage of Tissue from the Vagina
• Uterine Contractions
• Severe Back Pain
• Abnormal Vaginal Discharge

Common Causes

Prior to establishing a treatment plan for recurrent pregnancy loss, identifying the underlying etiological factors is essential.

Key etiological factors associated with repeated pregnancy losses include:

Endocrine issues

Endocrine conditions such as polycystic ovary syndrome (PCOS), thyroid disorders, diabetes mellitus, and pituitary dysfunction can cause hormonal imbalances contributing to pregnancy loss, with luteal phase deficiency (LPD) being a recognized contributing factor.

Immunological conditions

Autoimmune disorders and associated thrombophilic conditions can contribute to pregnancy loss through mechanisms impacting placental perfusion.

Genetic factors

Parental chromosomal arrangements or embryonic genetic mutations represent a frequent cause of recurrent pregnancy loss.

Congenital abnormalities

Uterine anatomical variations such as intrauterine adhesions, uterine septum, subseptate uterus, or leiomyomas can be implicated.

Cervical incompetence

Cervical insufficiency is associated with mid-trimester pregnancy loss due to structural weakness of cervical tissue.

Tests To Find The Cause

Accurate clinical management of recurrent miscarriages requires diagnostic evaluation to determine underlying causes. Recommended investigations include:

• Blood panels evaluating glycemic control, thyroid function, and autoimmune profiles.
• Parental karyotyping and genetic screening.
• Thrombophilia and coagulation studies.
• Hysterosalpingography, hysteroscopy, or pelvic ultrasound imaging to evaluate uterine anatomy.

Treatment Options

Medications

Prescribed pharmacological agents may include hormonal supplementation or anticoagulant therapy to manage underlying etiological conditions.

Surgical treatments

Surgical correction of structural uterine abnormalities or fibroids when indicated.

Fertility treatments

Assisted reproductive technologies such as IVF combined with preimplantation genetic testing (PGT) when genetic factors are identified.
