Recurrent Miscarriage: Causes, Tests & Treatment
Quick answer: Recurrent pregnancy loss is assessed by looking at the pattern of previous pregnancies and considering possible genetic, uterine, endocrine, metabolic and autoimmune factors. Depending on the history, a doctor may recommend ultrasound or other uterine imaging, selected blood tests, genetic testing or additional investigations. Treatment depends on what is found. Some causes can be treated or managed before or during pregnancy. When no specific cause is identified, care may focus on preconception counselling, appropriate monitoring and support during a future pregnancy. The content strategy for this pillar specifically calls for coverage of the definition, genetic and uterine causes, endocrine and antiphospholipid factors, the evaluation pathway, future pregnancy planning and the possible role of IVF or genetic testing.

Losing a pregnancy is difficult. Going through this more than once can leave a couple wondering why it is happening and whether anything can be done differently next time.
Recurrent miscarriage, also called recurrent pregnancy loss, can have several possible causes. These include chromosomal or genetic factors, problems affecting the uterus, antiphospholipid syndrome, thyroid and other endocrine conditions, and some metabolic or reproductive factors. In some couples, testing does not identify one clear cause.
The purpose of an evaluation is not to order every possible test. It is to understand the pregnancy history, look for causes that are relevant to that individual, and identify anything that could change treatment or future pregnancy care.
What does recurrent pregnancy loss mean?
- They may want to know
Recurrent pregnancy loss refers to repeated miscarriages or pregnancy losses. The terms recurrent miscarriage and recurrent pregnancy loss (RPL) are both used in clinical practice.
There is some variation between medical guidelines in exactly how recurrent pregnancy loss is defined and when investigations should begin. The number of losses, their timing and the details of each pregnancy can all matter.
For that reason, a fertility specialist will usually look beyond the number alone.
- How many pregnancies you have had
- How far each pregnancy had progressed
- Whether an ultrasound had confirmed a heartbeat
- Whether the pregnancy was located inside the uterus
- Whether any pregnancy tissue was tested
- Whether there were complications before or during the loss
- Whether either partner has a known medical or genetic condition
- Whether there is a history of infertility or fertility treatment
A detailed history can help narrow down which investigations are actually useful.
Why does recurrent miscarriage happen?
- Possible findings include
There is no single explanation for recurrent miscarriage.
Pregnancy depends on several processes working together. The embryo needs the right genetic information, implantation needs to occur in a suitable uterine environment, and maternal health and hormonal support also play important roles.
The main causes doctors consider include genetic factors, uterine or anatomical problems, antiphospholipid syndrome, endocrine conditions and other medical factors.
Genetic and Chromosomal Causes
Chromosomal abnormalities are an important cause of miscarriage, particularly during early pregnancy.
An embryo may develop with an abnormal number or arrangement of chromosomes. When this affects development significantly, the pregnancy may stop developing.
This does not necessarily mean that either parent has a genetic disease.
In some couples, however, one partner may carry a chromosome rearrangement such as a balanced translocation. The carrier may be completely healthy, but some embryos may receive an unbalanced chromosome arrangement.
This is one reason genetic counselling and, in selected situations, genetic testing may be considered.
Uterine or Anatomical Causes
The structure of the uterus can sometimes play a role in pregnancy loss.
- Certain congenital differences in the shape of the uterus
- Fibroids affecting the uterine cavity
- Endometrial polyps
- Intrauterine adhesions or scar tissue
- Other abnormalities involving the uterine cavity
Finding a fibroid or polyp does not automatically mean that it caused a miscarriage.
Its size, position and effect on the uterine cavity need to be considered alongside the pregnancy history. Treating an incidental finding without understanding its clinical relevance may not be helpful.
Antiphospholipid Syndrome
Antiphospholipid syndrome, usually shortened to APS, is an autoimmune condition associated with pregnancy complications, including recurrent pregnancy loss in some patients.
When the clinical history suggests APS, specific blood tests may be considered.
A single abnormal blood-test result does not necessarily establish the diagnosis. APS requires appropriate clinical and laboratory assessment.
This is important because confirmed APS can change the way a future pregnancy is managed.
Thyroid and Other Hormonal Factors
Thyroid disorders can affect reproductive health and pregnancy, so thyroid function may be assessed when appropriate.
Other endocrine or metabolic problems can also be relevant depending on the individual's history.
For example, a doctor may consider conditions affecting:
- Blood glucose
- Prolactin
- Ovulation
- Menstrual cycles
- General metabolic health
Having PCOS or a thyroid condition does not automatically explain recurrent miscarriage. The doctor needs to consider the complete clinical picture.
Other Factors
A recurrent pregnancy loss assessment may also take into account:
- Maternal age
- Previous pregnancy history
- Existing medical conditions
- Previous fertility treatment
- Medication history
- Male reproductive factors in selected cases
- Family history
- Findings from earlier pregnancy investigations
Sometimes no definite cause is found.
That can be frustrating, but it does not mean the losses were insignificant or that there is nothing more to discuss. It simply means that the available evaluation has not identified a specific explanation that can be acted upon.
Is recurrent miscarriage only a woman's problem?
No.
Pregnancy involves genetic material from both partners, as well as the embryo, uterus and several other biological processes.
Some genetic causes can involve either partner. In selected situations, male reproductive health may also form part of the assessment.
The important point is that recurrent pregnancy loss should not automatically be treated as something the woman has caused.
This matters even more when families or relatives place pressure on a woman after a miscarriage. Pregnancy loss is a medical issue, not a reason to assign blame.
What tests are done after recurrent miscarriage?
- The doctor may review
There is no single "recurrent miscarriage test."
The appropriate evaluation depends on the person's history.
A fertility specialist may recommend some investigations and not others. The aim is to answer specific clinical questions rather than collect as many reports as possible.
Pregnancy History Review
This is often the starting point.
- Gestational age at each loss
- Ultrasound findings
- Whether fetal cardiac activity was seen
- Symptoms before the miscarriage
- Previous treatment or procedures
- Genetic or pathology reports
- Previous pregnancy complications
- Menstrual and reproductive history
- Existing medical conditions
- Previous fertility treatment
Two people may have the same number of miscarriages but require very different evaluations because the circumstances were different.
Ultrasound and Uterine Imaging
Ultrasound can provide information about the uterus, endometrium and ovaries.
If a more detailed assessment is needed, the doctor may recommend another method of evaluating the uterine cavity.
The purpose is to look for structural findings that could potentially affect pregnancy.
A scan finding does not automatically mean that treatment is needed. Its significance depends on what the finding is, where it is located and whether it fits with the pregnancy history.
Antiphospholipid Antibody Tests
When appropriate, blood tests for antiphospholipid antibodies may form part of the evaluation.
These results need to be interpreted alongside the clinical history. A positive result on its own does not necessarily mean that a person has antiphospholipid syndrome.
If APS is diagnosed, the doctor can discuss what it means for a future pregnancy and whether treatment is required.
Thyroid and Metabolic Tests
Depending on the medical history, the doctor may assess thyroid function and other metabolic factors.
For example, additional assessment may be relevant when there is:
- Known thyroid disease
- Diabetes
- Irregular periods
- PCOS
- Symptoms suggesting another endocrine condition
The goal is to find a condition that matters to the person's reproductive and pregnancy health, rather than performing every hormone test available.
Genetic Testing
Genetic testing can sometimes provide useful information.
In selected circumstances, pregnancy tissue from a miscarriage may be tested to look for chromosomal abnormalities.
Parental chromosome testing may also be considered when the history suggests that one partner could carry a structural chromosome rearrangement.
Genetic counselling can be particularly useful here because genetic reports can be difficult to interpret without the right context.
Are More Tests Always Better?
Not necessarily.
A longer list of tests does not automatically mean a better evaluation.
The recurrent pregnancy loss strategy developed for Dr. Swati Shree specifically recommends a test-purpose approach, asking what each investigation is intended to answer rather than suggesting that every patient requires every possible test. Dr_Swati_Shree_Content_Strategy…
That approach can reduce unnecessary investigations and keep the discussion focused on findings that may actually affect care.
Can PCOS or thyroid problems cause recurrent miscarriage?
PCOS and thyroid disorders can be relevant to reproductive health, but neither should automatically be blamed for repeated pregnancy loss.
PCOS can affect ovulation and metabolic health. Thyroid disorders can affect pregnancy when thyroid function is not appropriately controlled.
If one of these conditions is present, the doctor may include its management in preconception planning.
The important distinction is between having a medical condition and proving that the condition caused a particular miscarriage. Those are not always the same thing.
The supporting content plan for this pillar specifically includes PCOS and thyroid-related pregnancy loss as a topic requiring evidence-qualified explanations rather than blanket statements. Dr_Swati_Shree_Content_Strategy…
How is recurrent miscarriage treated?
- The discussion may cover
There is no single treatment that works for every case.
Treatment should follow the cause when one is identified.
Treating a Uterine Abnormality
If a significant abnormality affecting the uterine cavity is found, treatment may sometimes be recommended.
Depending on the problem, this can involve a procedure to remove or correct the abnormality.
However, not every fibroid, polyp or uterine variation needs treatment. The possible benefit of intervention should be considered in the context of the patient's actual history.
Managing Antiphospholipid Syndrome
When APS is properly diagnosed, specific treatment may be used during pregnancy.
The exact medication plan depends on the individual situation and must be prescribed by a doctor.
Aspirin or blood-thinning medication should not be started simply because someone has read that it may help recurrent miscarriage.
Managing Thyroid or Metabolic Conditions
If thyroid disease, diabetes or another endocrine or metabolic condition is identified, appropriate management can form part of preconception care.
The doctor may also recommend monitoring during pregnancy.
The aim is to address a real medical condition, rather than treating a laboratory result in isolation.
Cervical Insufficiency
Cervical insufficiency is different from many causes of early miscarriage.
In some women, the cervix may open too early during pregnancy, particularly in a history suggestive of second-trimester pregnancy loss.
Depending on the history, an obstetrician may discuss closer cervical monitoring or a procedure such as cervical cerclage.
This is not appropriate for every woman who has experienced miscarriage.
Progesterone
Progesterone supports the uterine lining and early pregnancy.
Progesterone treatment may be considered in certain clinical situations, depending on the pregnancy history and other findings.
It is not a universal treatment for recurrent miscarriage.
Whether it is appropriate, and how it should be used, should be decided by the treating doctor.
Genetic Counselling
When genetic testing identifies or raises suspicion of a chromosomal issue, genetic counselling can help the couple understand what the result means.
- Whether either parent carries a chromosome rearrangement
- What the result could mean for another pregnancy
- Whether further testing is useful
- Whether assisted reproduction should be considered
- What options are available based on the couple's circumstances
The value of genetic counselling is often in making a complicated report easier to understand and putting it into the context of future pregnancy planning.
When is IVF considered after recurrent miscarriage?
Recurrent miscarriage does not automatically mean that IVF is necessary.
IVF may be discussed when there is another reason for assisted reproduction, such as infertility, or in selected genetic situations where embryo testing becomes part of the treatment discussion.
The decision depends on the couple's complete reproductive history.
Factors that may influence the discussion include:
- Age
- Ovarian reserve
- Sperm factors
- Previous fertility treatment
- Genetic findings
- Number and pattern of pregnancy losses
- Other fertility diagnoses
IVF also cannot guarantee that miscarriage will not occur.
For patients who need advanced ART, Dr. Swati Shree can evaluate them at EVE Women and Fertility Clinic and guide treatment through partner fertility centres in Bangalore. EVE's ART Level 1 scope includes fertility assessment, counselling, ovulation induction, follicle monitoring and IUI. Advanced IVF laboratory procedures are carried out through partner facilities.

Does embryo genetic testing prevent miscarriage?
Embryo genetic testing may be discussed in selected circumstances, particularly when there is a relevant genetic concern.
It is not a routine answer for every couple experiencing recurrent miscarriage.
The decision depends on the reason for considering IVF, the genetic findings, age, embryo availability and other factors.
It is also important to understand what genetic testing can and cannot tell you. Testing can provide information about specific genetic characteristics, but it cannot guarantee implantation, an ongoing pregnancy or a healthy baby.
What should you do before trying again?
After repeated pregnancy loss, it is reasonable to pause and review the situation before trying again.
A preconception appointment can be useful for reviewing:
- Previous pregnancy records
- Ultrasound reports
- Genetic or pathology results
- Current medicines
- Existing medical conditions
- Thyroid or metabolic health
- Previous fertility treatment
- The plan for the next pregnancy
There is no universal waiting period that applies to every person after pregnancy loss. The appropriate timing can depend on physical recovery, emotional readiness and the circumstances of the miscarriage.
Your doctor can advise you based on what happened and your current health.
What happens after a positive pregnancy test?
- Depending on the situation, this may involve
A positive pregnancy test after recurrent miscarriage can bring mixed emotions.
You may feel happy, but you may also feel nervous about becoming attached to the pregnancy. That does not mean you are being negative. It is a common emotional response after loss.
Your doctor may create an early pregnancy plan based on your previous history.
- Confirming the pregnancy appropriately.
- Checking hCG when clinically indicated.
- Arranging an early ultrasound at the appropriate time.
- Reviewing medicines and existing medical conditions.
- Monitoring the pregnancy more closely if there is a clinical reason.
- Explaining which symptoms should prompt medical attention.
The exact schedule varies from person to person.
Which symptoms need urgent attention in early pregnancy?
- Seek urgent medical assessment if you have
Some symptoms should not wait for a routine appointment.
- Heavy vaginal bleeding
- Severe or increasing abdominal or pelvic pain
- Pain mainly on one side
- Shoulder-tip pain, particularly with bleeding or pelvic pain
- Fainting or significant dizziness
- Fever
- Severe weakness or feeling acutely unwell
Bleeding combined with one-sided pelvic pain, shoulder-tip pain or fainting can be a warning sign of an ectopic pregnancy.
If symptoms are severe, seek emergency medical care rather than waiting for your fertility clinic appointment.
Can stress cause recurrent miscarriage?
After a miscarriage, people often replay everything they did during the pregnancy.
Was work too stressful? Was there too much travel? Did exercise cause a problem? Did something eaten or done during the pregnancy lead to the loss?
This kind of self-blame is understandable, but it is not a useful way to approach recurrent pregnancy loss.
Ordinary emotional stress should not automatically be treated as the cause of repeated miscarriage.
At the same time, emotional wellbeing matters. Recurrent pregnancy loss can affect sleep, relationships, work and confidence about trying again. Counselling or other emotional support can be helpful.
Support should complement medical care, not replace it.
Does bed rest prevent miscarriage?
Routine bed rest is not a general treatment for recurrent miscarriage.
A miscarriage caused by a chromosomal problem, for example, cannot be prevented by simply remaining in bed.
Advice about activity after a miscarriage or during a subsequent pregnancy should be based on the person's medical situation.
If someone recommends complete bed rest, avoiding all exercise or stopping normal activities, it is worth discussing that advice with the treating doctor rather than assuming it is necessary.
Lifestyle changes before pregnancy
Healthy habits can support general health before and during pregnancy, although they cannot prevent every miscarriage.
Useful areas to discuss with your doctor include:
- Avoiding tobacco
- Avoiding alcohol when trying to conceive and during pregnancy
- Reviewing regular medicines before conception
- Managing known medical conditions
- Eating a balanced diet
- Maintaining appropriate physical activity
- Getting adequate sleep
- Taking prenatal supplements recommended by your doctor
- Attending preconception appointments
These steps should not be presented as a guarantee against pregnancy loss.
A previous miscarriage does not mean that a woman failed to follow the "right" lifestyle.
Common misconceptions about recurrent miscarriage
"One miscarriage means something is seriously wrong."
Not necessarily.
Miscarriage can happen for many reasons. One loss does not automatically mean that a person has recurrent pregnancy loss or an underlying fertility problem.
"Recurrent miscarriage is always caused by the woman."
No.
Genetic factors can involve either partner, and pregnancy loss can have several possible causes.
"Normal tests mean nothing can be done."
Not necessarily.
Sometimes the available evaluation does not identify a clear cause. Preconception counselling and appropriate early pregnancy care can still be useful.
"IVF prevents miscarriage."
IVF does not guarantee that a pregnancy will continue normally.
It may be appropriate for some couples for specific fertility or genetic reasons, but it is not automatically required after recurrent miscarriage.
"Aspirin prevents miscarriage."
Aspirin has specific medical uses. It should not be started without medical advice simply because someone has experienced pregnancy loss.
"Bed rest is the safest thing after miscarriage."
Routine bed rest is not a universal treatment for miscarriage or recurrent pregnancy loss. Activity recommendations should be individualized.
Questions to ask your fertility specialist
- Consider asking
It can help to take your previous medical records to the appointment.
- Does my pregnancy history require a recurrent pregnancy loss evaluation?
- Which causes are relevant in my case?
- Which tests would actually change my treatment or pregnancy plan?
- Does my partner need any evaluation?
- Should we consider genetic counselling?
- Does my uterus need a more detailed assessment?
- Should I be tested for thyroid or metabolic problems?
- Is antiphospholipid syndrome relevant to my history?
- Is there anything that should be treated before conception?
- What will monitoring look like in the next pregnancy?
- When should I contact you after a positive pregnancy test?
- Is IVF or embryo genetic testing relevant to my situation?
When should you see a fertility specialist?
A fertility specialist can be helpful when pregnancy losses have happened repeatedly or when you want a structured review before trying again.
Earlier assessment may be particularly useful when there is:
- A known genetic condition
- A suspected uterine abnormality
- A history suggestive of antiphospholipid syndrome
- Thyroid or metabolic disease
- Infertility alongside pregnancy loss
- Previous fertility treatment
- Pregnancy loss later in pregnancy
- A family history suggesting a genetic condition
- Concern about planning another pregnancy
The aim is not simply to find a label. It is to understand what happened, identify anything treatable and decide what should be done differently, if anything, in a future pregnancy.
For couples in Gunjur and other parts of East Bangalore, a consultation with Dr. Swati Shree at EVE Women and Fertility Clinic can provide an opportunity to review previous pregnancy records and discuss an individualized evaluation.

Final Thoughts
- Medical Disclaimer
- This article is for educational purposes only and does not replace professional medical advice. Fertility and pregnancy outcomes vary from person to person. Please consult a qualified doctor for diagnosis and treatment.
Repeated miscarriage can make the next pregnancy feel frightening before it has even begun. It is normal to have questions about why it happened and whether something can be done to reduce the risk in the future.
There is no single recurrent miscarriage test and no treatment that applies to everyone. A careful review of the previous pregnancies, followed by targeted investigations, is usually more useful than a long list of unrelated tests.
Sometimes a clear cause is found and treatment can be offered. Sometimes the investigations are reassuring but do not provide a definite explanation. Both situations deserve proper medical care and honest counselling.
If you have experienced recurrent pregnancy loss, discussing your history with a reproductive medicine specialist can help you understand what should be investigated and how a future pregnancy can be planned.

FAQs
How many miscarriages are considered recurrent pregnancy loss?
The definition of recurrent pregnancy loss can vary between medical guidelines and clinical situations. Doctors consider not only the number of miscarriages but also when they occurred, previous ultrasound findings, genetic results and the couple's medical history. A fertility specialist can determine whether an evaluation is appropriate.
What is the most common cause of recurrent miscarriage?
There is no single cause that explains every case. Chromosomal abnormalities are an important cause of pregnancy loss, particularly early in pregnancy. Other possibilities include uterine abnormalities, antiphospholipid syndrome, endocrine conditions and genetic factors involving a parent. Some couples have no identifiable cause after evaluation.
What blood tests are done for recurrent miscarriage?
Blood tests are selected according to the patient's history. They may include testing related to antiphospholipid syndrome, thyroid function and selected endocrine or metabolic conditions. Genetic testing may also be discussed in appropriate cases. A doctor should decide which tests are useful rather than ordering every available blood test.
Can thyroid problems cause recurrent miscarriage?
Thyroid disorders can affect pregnancy, particularly when thyroid function is not appropriately managed. However, thyroid disease should not automatically be assumed to be the cause of recurrent miscarriage. A doctor can assess thyroid function and consider the result alongside the complete pregnancy and medical history.
Can recurrent miscarriage be treated?
Treatment depends on the underlying cause. Depending on the findings, management may include treating an identified medical condition, addressing certain uterine abnormalities, managing antiphospholipid syndrome or providing genetic counselling. When no cause is identified, preconception planning and appropriate monitoring during a future pregnancy may still be useful.
Is IVF recommended for recurrent miscarriage?
IVF is not automatically recommended after recurrent miscarriage. It may be considered when there is another fertility indication or when particular genetic circumstances make assisted reproduction relevant. Embryo genetic testing may be discussed in selected cases, but IVF cannot guarantee that a future pregnancy will continue normally.
Can I have a healthy pregnancy after recurrent miscarriage?
Yes, a healthy future pregnancy can be possible after recurrent pregnancy loss. The appropriate care depends on factors such as age, medical history, previous pregnancy findings and test results. No treatment can guarantee a particular outcome, but identifying a treatable cause and planning early pregnancy care can help guide management. Yes, most couples do. Even after several losses, a good share of next pregnancies succeed, especially once treatable causes are found. Early supportive monitoring in the next pregnancy helps.
Where can recurrent miscarriage be evaluated in Bangalore?
Recurrent pregnancy loss can be assessed by a gynecologist or fertility specialist with experience in reproductive medicine. Dr. Swati Shree provides fertility evaluation at EVE Women and Fertility Clinic in Gunjur, Bangalore, where the assessment can be tailored to the individual's previous pregnancy history and medical findings.
