Experiencing a miscarriage can be emotionally and physically challenging. When pregnancy loss happens more than once, couples may experience additional anxiety and uncertainty about future pregnancies. Understanding the possible causes of repeated abortions or miscarriages is an important step towards appropriate medical evaluation and treatment.

Recurrent pregnancy loss is generally defined as two or more pregnancy losses, although definitions and evaluation guidelines can vary. It is important to distinguish spontaneous miscarriages from induced abortions because they are medically different situations.

Not every miscarriage has the same cause, and sometimes a definite explanation cannot be identified even after detailed testing.

What Are Recurrent Miscarriages?

A miscarriage refers to the loss of a pregnancy before the stage of fetal viability. Recurrent pregnancy loss refers to multiple pregnancy losses.

Pregnancy loss may occur due to chromosomal abnormalities, hormonal conditions, uterine abnormalities, immune-related conditions, or other medical factors.

A specialist evaluation can help determine whether an identifiable condition is contributing to repeated losses.

Common Causes of Repeated Miscarriages

1. Chromosomal Abnormalities

Chromosomal abnormalities in an embryo are an important cause of early pregnancy loss. These abnormalities may occur randomly during egg or sperm development or fertilisation.

The likelihood of certain chromosomal abnormalities increases with maternal age.

2. Uterine Abnormalities

Structural differences in the uterus may sometimes affect implantation or pregnancy development.

Examples include:

• Uterine septum.

• Certain types of fibroids.

• Endometrial polyps.

• Intrauterine adhesions.

Not every uterine abnormality affects pregnancy, so treatment decisions require careful assessment.

3. Hormonal and Metabolic Conditions

Uncontrolled thyroid disorders and poorly controlled diabetes may affect pregnancy outcomes. Some women with PCOS may also have associated metabolic or hormonal concerns that require evaluation.

4. Antiphospholipid Syndrome

Antiphospholipid syndrome is an autoimmune condition associated with an increased risk of blood clots and pregnancy complications. Specific blood tests may be recommended when recurrent pregnancy loss is suspected.

5. Age-Related Factors

As women grow older, the proportion of eggs with chromosomal abnormalities increases. This can contribute to difficulties with conception and a higher risk of miscarriage.

Tests Recommended for Recurrent Pregnancy Loss

The investigations depend on medical history and the number and timing of pregnancy losses.

A specialist may recommend:

• Detailed reproductive and pregnancy history.

• Pelvic ultrasound.

• Uterine cavity assessment.

• Thyroid function testing.

• Diabetes screening when appropriate.

• Antiphospholipid antibody testing.

• Genetic evaluation in selected cases.

• Additional investigations based on clinical findings.

Routine extensive testing is not necessary for every patient.

Treatment Options for Repeated Miscarriages

Treatment depends on the underlying cause.

Managing Hormonal Conditions

Thyroid disorders and diabetes should be appropriately managed before and during pregnancy.

Treating Uterine Conditions

Certain structural abnormalities may require surgical correction when they are clearly associated with pregnancy complications.

Managing Antiphospholipid Syndrome

Patients diagnosed with antiphospholipid syndrome may benefit from specialist-directed treatment, which can include specific blood-thinning medication during pregnancy.

Genetic Counselling

Couples with identified chromosomal rearrangements or relevant genetic concerns may benefit from genetic counselling to understand reproductive options.

IVF and Genetic Testing

In selected situations, IVF with preimplantation genetic testing for aneuploidy (PGT-A) may be discussed. However, PGT-A is not a guaranteed solution for recurrent miscarriage and is not appropriate for every couple.

Emotional Support Is an Important Part of Care

Repeated pregnancy loss can create feelings of grief, frustration, and uncertainty. Emotional support, counselling, and open communication with healthcare professionals are important parts of care.

Couples should not blame themselves for miscarriage. Many pregnancy losses happen because of biological factors beyond an individual's control.

Consult Dr. Riddhi Doshi for Recurrent Pregnancy Loss Evaluation

If you have experienced repeated abortions or miscarriages, a personalised medical evaluation can help identify possible contributing factors and appropriate treatment options.

Dr. Riddhi Doshi can provide guidance regarding fertility assessment and the investigations that may be relevant to your medical history.

With the right evaluation, patients can better understand their reproductive health, discuss available options, and plan future pregnancies with informed medical support.
