Recurrent miscarriage is a condition when there has been three or more successive pregnancy losses. It is different from infertility as, infertility is the inability to conceive. For many cases, the cause of a recurrent miscarriage has not always been found. A number of factors can cause recurrent miscarriages of which some are treatable.It may not always be possible to identify a cause for recurrent miscarriage in a couple, even after extensive research and treatment procedures. Some of the common causes of recurrent miscarriage are described below:
1. Chromosomal abnormalities: Incompatible chromosomes can result into pregnancy losses. When an egg and a sperm meet, of which one of them is faulty, they can't line up properly resulting into chromosomal abnormality. Such conditions lead to miscarriages.
2. Uterine abnormalities or Incompetent cervixes: Miscarriages occur if the uterus is abnormally shaped since the embryo is not properly implanted or even if it gets implanted, it may not get sufficient nourishment to survive. If the woman has a weak cervix, it cannot hold the developing embryo, leading to miscarriage.
3.  Immunologic disorders: Under rare cases, the embryo itself is not accepted by the body. Antiphospholipid antibodies are those, which attack self tissues, such as embryos and prevent them from building up. This leads to recurrent miscarriage.
4. Untreated thyroid problems: Conditions such as thyroid or uncontrolled diabetes result in uterine conditions which make it tough for the embryos to survive.
5. Polycystic ovary syndrome: Women with polycystic ovary syndrome tend to have high levels of male hormones which, result in irregular menstruation and ovulation. This can prevent the lining of the endometrium from maturing that is required for holding the embryo.
6. Bacterial infections: There may be presence of a number of microorganisms inside the reproductive tract that may be harmless for the person. But there may be certain bacteria lined up in the reproductive tract, which can prevent development of embryo, thus leading to miscarriages.
7.  Lifestyle: Smoking and drinking are harmful lifestyle habits, which may increase the chance of miscarriage to a great extent. It is always advised to avoid smoking or drinking when you wish to conceive. Other lifestyle conditions, such as working in certain environments like hospital environments, farms, laboratories, etc, may lead to miscarriages; however, the exact reason has not been identified yet.

Reasons For Recurrent Miscarriage

Recurrent pregnancy loss is termed as the occurrence of three or more miscarriages. Recently, the American Society for Reproductive Medicine has altered the definition and limited the number of miscarriages to two. A pregnancy loss can only be termed so if the pregnancy is clinically recognized and is ends involuntarily before 20 weeks. The pregnancy loss must be identified by a registered doctor to term it as pregnancy loss.

What are the major causes of Recurrent Pregnancy Loss?
There could be a lot of reasons behind recurrent pregnancy loss. Most of the pregnancy failure happens from reasons such as abnormalities of the genes, chromosomes and other random events. It is estimated that close to 15 percent of the pregnancies end up in miscarriages. While 30-60 percent of the pregnancies expire within the first 12 weeks, fifty percent of the women are believed to be not aware of the pregnancy in the first place. The risk of miscarriage, however, is less than 50 percent.

An advanced maternity age is another crucial factor towards recurrent 2pregnancy loss. The risk of miscarriage dramatically increases among these women owing to their poor quality of egg, abnormalities in the chromosome etc. At a time, it has been observed that either the father or the mother might have irregularities in the gene leading to early miscarriage.

An abnormality in the uterus might also be a reason for a miscarriage. Poor blood supply and inflammation of the uterus are two of the topmost reason for miscarriages among many women. While some women born with a defective uterus, some develop uterus anomalies due to lifestyle and unhealthy life practices.

Last but not the least, a woman s immune system might also play a pivotal role towards a miscarriage. Certain hormonal irregularities, diabetes and thyroid diseases might lead to a miscarriage. Then there are the environmental factors such as stress, occupational factors, lifestyle practices etc that contributes towards a miscarriage.

What are the tests conducted?
To evaluate the exact reason for repeated miscarriages, a doctor performs a detailed physical and surgical examination. Some other areas where a doctor sneaks into include family history, genetic history etc. A karyotype test might also be prescribed in case a doctor feels the need of doing so. The uterus cavity and the uterus are closely monitored to understand any potential lack in the anatomy. This is followed by a list of imaging tests that a doctor might prescribe. These include MRI, X-ray, hysteroscopy etc.

What are the treatment options?
The treatment options are decided based on the finding of the tests. Sometimes plain medicines along with antibiotics can cure the condition, while sometimes surgery might be required to fix any potential threat within the uterus. In any case, the probability of future pregnancy after treatment goes as high as 77 percent.


Recurrent Pregnancy Loss - Things You Should Avoid!

If you lose a baby before 24 weeks of pregnancy, it is called a miscarriage. If this happens in the first 3 months of pregnancy, it is known as an early miscarriage. Unfortunately, early miscarriages are common, with 10 20 in 100 (10 20%) pregnancies ending this way. Late miscarriages, after 3 months of pregnancy but before 24 weeks, are less common: 1 2 in 100 (1 2%) pregnancies end in a late miscarriage. When a miscarriage happens three or more times in a row, it is called recurrent miscarriage. Recurrent miscarriage affects 1 in 100 (1%) couples trying to have a baby.

Why does recurrent miscarriage and late miscarriage happen?

Sometimes there is a reason found for recurrent and late miscarriage. In other cases, no underlying problem can be found. Most couples are likely to have a successful pregnancy in the future, particularly if test results are normal.

There are a number of factors that may play a part in causing recurrent and late miscarriage:

Age, the older you are, the greater your risk of having a miscarriage. If the woman is aged over 40, more than 1 in 2 pregnancies end in a miscarriage. Miscarriages may also be more common if the father is older.
Antiphospholipid syndrome (APS- a syndrome that makes your blood more likely to clot) is uncommon but is a cause of recurrent miscarriage and late miscarriage.
Thrombophilia (an inherited condition that means that your blood may be more likely to clot) may cause recurrent miscarriage and in particular late miscarriages.
Genetic factors, about 2 5 in 100 couples (2 5%) with recurrent miscarriage, one partner will have an abnormality on one of their chromosomes (the genetic structures within our cells that contain our DNA and the features we inherit from our parents). Although this may not affect the parent, it can sometimes cause a miscarriage
Weak cervix is known to be a cause of miscarriage from 14 to 23 weeks of pregnancy. This can be difficult to diagnose when you are not pregnant. It may be suspected if in a previous pregnancy your waters broke early, or if the neck of the womb opened without any pain.
Developmental problems of the baby may lead to a miscarriage but are unlikely to be the cause of recurrent miscarriage.
Infection that makes you very unwell can cause a miscarriage. Milder infections that affect the baby can also cause a miscarriage. The role of infections in recurrent miscarriage is unclear.
An abnormally shaped uterus may contributes to recurrent miscarriage or late miscarriages. However, minor variations do not appear to cause miscarriage.
Diabetes and thyroid problems can be factors in miscarriages. They do not cause recurrent miscarriage, as long as they are treated and kept under control.
It has been suggested that some women miscarry because their immune system does not respond to the baby in the usual way. This is known as an alloimmune reaction. There is no clear evidence to support this theory at present. Further research is needed.
Are there any other risk factors?

Being overweight increases the risk of miscarriage. Smoking and too much caffeine may also increase the risk. Excessive alcohol is known to be harmful to a developing baby and drinking five or more units a week may increase the risk of miscarriage.

The chance of a further miscarriage increases slightly with each miscarriage. Women with three miscarriages in a row have a 4 in 10 chance of having another one. This means that 6 out of 10 women (60%) in this situation will go on to have a baby next time. 

Why are investigations helpful?

Finding out whether there is a cause for your recurrent miscarriage or late miscarriage is important as your doctor will be able to give you an idea about your likelihood of having a successful pregnancy. In a small number of cases there may be treatment available to help you.

What investigations might be offered?

Blood tests:

For APS- APS is diagnosed if you test positive on two occasions 12 weeks apart, before you become pregnant again.
For thrombophilia- If you have had a late miscarriage you should be offered blood tests for certain inherited thrombophilias.
To check you and your partner s chromosomes for abnormalities. You may be offered this test if your baby has been shown to have abnormal chromosome
Tests for abnormalities in the baby You should be offered tests to check for abnormalities in your baby s chromosomes. This is not always possible but may help to determine your chance of miscarrying again. If you have had a late miscarriage you may also be offered a postmortem examination of your baby. This will not happen without your consent and you will have the opportunity to discuss this with your health team beforehand.

Tests for abnormalities in the shape of your uterus. You should be offered a pelvic ultrasound scan to check for any abnormalities in the shape of your uterus. If an abnormality is suspected, further investigations may include a hysteroscopy (a procedure to examine the uterus through a small telescope which is passed through the vagina and cervix) or a laparoscopy (a procedure in which a surgeon uses a fine telescope to look inside the abdomen and pelvis).

Tests for infection. If you have had a late miscarriage, tests such as blood samples and vaginal swabs may be taken at the time to look for any source of infection.




What are my treatment options?

Treatment for APS

If you have APS and have had recurrent miscarriage or a late miscarriage, treatment with low-dose aspirin tablets and heparin injections in pregnancy increases your chance of having a baby. Aspirin and heparin make your blood less likely to clot and are safe to take in pregnancy.

Having APS means you are at increased risk of complications during pregnancy such as pre-eclampsia, problems with your baby s growth and premature birth. You should be carefully monitored so that you can be offered treatment for any problems that arise.

Treatment for thrombophilia

If you have an inherited tendency to blood clotting (thrombophilia) and have had a miscarriage between 12 and 24 weeks of pregnancy, you should be offered treatment with heparin. At present there is not enough evidence to say whether heparin will reduce your chance of miscarriage if you have had early miscarriages (up to 12 weeks of pregnancy). However, you may be still offered the treatment to reduce the risk of a blood clot during pregnancy.

Your doctor will discuss what would be recommended in your particular case.

Referral for genetic counselling

If either you or your partner has a chromosome abnormality, you should be offered the chance to see a specialist called a clinical geneticist. They will discuss with you what your chances are for future pregnancies and will explain what your choices are. This is known as genetic counselling.

Monitoring and treatment for a weak cervix

If you have had a miscarriage between 14 and 24 weeks and have a diagnosis of a weak cervix, you may be offered an operation to put a stitch in your cervix. This is usually done through the vagina at 13 or 14 weeks of pregnancy under a general or spinal anaesthetic. Your doctor should discuss the surgery with you.

If it is unclear whether your late miscarriage was caused by a weak cervix, you may be offered vaginal ultrasound scans during your pregnancy to measure the length of your cervix. This may give information on how likely you are to miscarry. If your cervix is shorter than it should be before 24 weeks of pregnancy, you may be offered an operation to put a stitch in your cervix.

Surgery to the uterus

If an abnormality is found in your uterus, you may be offered an operation to correct this.

Hormone treatment

Taking progesterone or human chorionic gonadotrophin hormones early in pregnancy has been tried to prevent recurrent miscarriage. More evidence is needed to show whether this works.

Immunotherapy

Treatment to prevent or change the response of the immune system (known as immunotherapy) is not recommended for women with recurrent miscarriage. It has not been proven to work, does not improve the chances of a live birth and may carry serious risks (including transfusion reaction, allergic shock and hepatitis).

What if no cause is found?

Where there does not appear to be a cause for recurrent miscarriage or late miscarriage, there is currently no evidence that heparin and aspirin treatment reduces the chance of a further miscarriage. For that reason this treatment is not recommended in these circumstances.

What does this mean for us in the future?

You and your partner should be seen together by a specialist health professional. Your doctor will talk to you both about your particular situation and your likelihood of having a further miscarriage and a successful pregnancy. If a cause has been found, possible treatment options will be offered to you to improve your chance of a successful pregnancy.

For couples where no cause for recurrent miscarriage has been found, 75 in 100 (75%) will have a successful pregnancy with this care. It is worth remembering that the majority of couples will have a successful pregnancy the next time even after three miscarriages in a row.

Recurrent And Late Miscarriage - Tests & Treatment For Couples!

Miscarriage refers to the spontaneous loss of the fetus before one completes the 20th week of pregnancy, taking into account the period from the conception to gestation.  It usually happens in the first trimester of the pregnancy; that is within the seventh and the twelfth week of conception. Recurrent miscarriage is when one suffers from multiple miscarriages in a row.

Possible Causes:

Abnormally-shaped Uterus: Some miscarriages, particularly late ones, are thought to happen because the uterus (womb) has an abnormal shape.
Polycystic Ovary Syndrome (PCOS): Women with this condition have many small cysts in their ovaries.They also tend to have hormonal problems, including high levels of insulin and male hormone in the blood, which can lead to recurrent miscarriage.
Infection: Some serious infections can cause or increase the risk of single miscarriages. These include toxoplasmosis, rubella, listeria and genital infection. But it is not clear whether infection plays a role in recurrent miscarriage.
Diabetes and Thyroid Problems: Uncontrolled diabetes and untreated thyroid problems can cause miscarriage. But well-controlled diabetes and treated thyroid problems do not cause recurrent miscarriage.
Risk Factors:
Your risk of recurrent miscarriage is higher if:

you and your partner are older; the risk is highest if you are over 35 and your partner over 40; 
you are very overweight. Being very underweight may also increase your risk.
Each new pregnancy loss increases the risk of a further miscarriage. But even after three miscarriages, most couples will have a live baby next time.

Testing After Recurrent Miscarriage:

If you have had three miscarriages in a row, you should be offered tests to try to find the cause. This should happen whether or not you already have one or more children. Testing is not usually offered after one or two early miscarriages (up to 14 weeks) because these are often due to chance. But you might be offered tests after two early miscarriages if you are in your late 30s or 40s or if it has taken you a long time to conceive.
If you had a late (second trimester) miscarriage, where your baby died after 14 weeks of pregnancy, you should be offered tests after this loss.

You can opt for blood tests to check for sticky blood syndrome or APS. Tests would look for antibodies that would help treat the condition. Antibodies are chemicals produced by the body to combat infections.
Get an examination done should the doctor suspect chromosomal abnormalities and in case it is diagnosed, both of you can consult a clinical genetics specialist for genetics counseling.
Your doctor will recommend an ultrasound scan to trace any type of abnormality that may make a pregnancy futile, for instance, a short or a fragile cervix.
Your hopes:

It is natural to pin your hopes on testing as the answer to your problems. But there are three reasons why it may not be the answer you re looking for:

A cause may not be found; when this happens your miscarriages are called  unexplained 
Even if a cause is found, it may not be treatable;
Treatment may not lead to a successful pregnancy. This can happen if a pregnancy miscarries for a different reason than the one being treated.

Understanding Miscarriages

For a mother, a miscarriage is the last thing she would want to hear. It can pin her down psychologically, leading to trauma and stress in unfathomable measures. To understand miscarriage better: it is a condition wherein there is a loss of pregnancy within the first 22 weeks of getting pregnant. The primary symptom of a miscarriage is bleeding from the vagina. So if you experience vaginal bleeding during this phase, then consult a doctor for further guidance.

Why do they occur?
There are many reasons as to why a miscarriage may occur and no study has been able to put a finger on any one specific cause. Having said that, miscarriages are mainly caused due to the presence of unusual chromosomes in the baby. Chromosomes are genetic material that directs the growth and development of a baby. Chromosomes present in either excess numbers or less can hinder the development of the baby. If the miscarriage occurs during the second trimester (14th to 26th week), then it can be accrued to a health anomaly in the mother. A miscarriage may also occur because of a weak cervix as a weak cervix will not be able to hold a pregnancy. This condition is called cervical insufficiency and occurs when the woman is in her second trimester.

Is it possible to prevent them?
In most cases, miscarriages cannot be prevented. For women who have suffered multiple miscarriages, multiple medications might be required to help with their subsequent pregnancies. Following a healthy lifestyle is recommended as it can minimize the risk of a miscarriage. One must abstain from smoking and substance abuse and limit consumption of alcohol in order to keep the body in optimal condition. It is advised to maintain optimal weight levels and eat a well-balanced diet.

Post miscarriage
A miscarriage is a very traumatic experience for a mother to be; it can be emotionally debilitating. That is the reason counseling can help in times such as these. Start planning for a baby only once the symptoms have subsided and you have also had a period post the miscarriage. It is important to make sure that you are physically and emotionally ready to have a baby. Remember, a miscarriage doesn t mean the end of the world. One can enjoy a fully healthy and a successful pregnancy even after a miscarriage.

Miscarriage - Why it Happens?

Miscarriage is the early loss of foetus within 20 weeks of pregnancy. It is also known as  spontaneous abortion . According to research, about 8-20% of the pregnancies end in miscarriage. Out of the total number of miscarriages, 80% of them end within 12 weeks of pregnancy.

Types of Miscarriages and their Symptoms 

Threatened Miscarriage   As the term suggests, in this condition the process of miscarriage might have begun. This is the initial stage of the process. In threatened miscarriage, there is slight bleeding accompanied by cramps and pain in the lower back, which is usually mild. The cervix (the lower part of the uterus) remains closed. 
Inevitable and Incomplete Miscarriage   In these conditions, there is bleeding along with an open cervix. When there is dilatation and thinning of the cervix, miscarriage is inevitable. In incomplete miscarriage, part of the tissue comes out and a part remains inside the uterus. In inevitable and incomplete abortions, the bleeding and cramps are more severe. 
Complete Miscarriage   Complete miscarriage is when the embryo has completely emptied from the uterus. The pain and bleeding reduce once the foetus is expelled. This can be confirmed through ultrasound. 
Missed Miscarriage   In Missed miscarriage, there is no sign of the life of the embryo and there is no expulsion of the embryo. It can be detected from the absence of heartbeat of the embryo found on ultrasound. 
Recurrent Miscarriage   It happens when there are two or three miscarriages one after the other. It affects about 1% of the pregnancies. 
Risk Factors 

Increased maternal age i.e., women above 35 years. 
Excess or insufficient chromosome in embryo. 
Placenta is the organ which links mother and the baby for blood supply. Problem in the development of placenta can cause miscarriage. 
Excessive smoking and drinking during pregnancy. 
Obese women have higher risk of miscarriage. 
Long-term health conditions like high blood sugar, high blood pressure, liver disease etc.
Infections like rubella, malaria etc. 
Weakened cervix, which is the result of previous injury or surgery, can also result in miscarriage. 
What are the symptoms of a miscarriage? 

Bleeding or spotting can be one of the symptoms of miscarriage. It should be kept in mind that not all pregnant women who suffer from spotting or bleeding, end in miscarriage. 
Lower backache starts before or right after bleeding, which can be persistent or you could have cramps which may be mild or sharp and can feel like more of pelvic pressure. 
Missed miscarriages are detected through ultrasound when the doctor finds that there is no heartbeat of the embryo or when the uterus is not growing. 
What are the treatment options in miscarriage? 

Medical   In most of the cases, there are no specific drugs to stop a miscarriage from occurring. In some cases, certain hormonal preparations help. There is no point in prescribing medicines for prevention of miscarriage if there is heavy bleeding. 
Surgery   Dilatation and evacuation (D&E) is a simple operation which is done under general/local anaesthesia. In this operation, the cervical canal is dilated and contents present in the uterus are evacuated. There is no cutting involved as it happens through the vagina. The process needs only five to ten minutes, but the patient has to stay in the hospital for about 3-4 hours. 
This process is opted when: 

There is heavy bleeding. 
The patient suffers from missed miscarriage. 
What can you do to prevent miscarriage? 

Nothing much can be done to prevent miscarriage in most of the cases. However, following supportive measures may help: 

There should not be overexertion during pregnancy. Moderate amount of physical activity is permissible. 
One should have a well-balanced diet. Studies have shown that a diet loaded with fruits and veggies helps in overall well-being during pregnancy. One should limit the consumption of caffeine. 
Avoid smoking, alcohol and certain drugs to prevent miscarriage. 
Avoid stress and anxiety. 
Report to Doctor (preferably Obstetrician) as soon as any symptom related to miscarriage appears.
