How To Deal With Repeated Pregnancy Loss | Causes And Treatment

Pregnancy loss is when pregnancy becomes non viable and ends up with spontaneous abortion. The urine tests come to be positive and after about 5 weeks one should be able see gestational sac on sonography. At around 6-7 weeks a small foetal pole appears with a cardiac activity. If that doesn’t come up at that time or even later at around 8 weeks or so or if its comes up  at 6-7 weeks and then disappears at around 8-10 weeks, then these pregnancies are known as non-viable gestations and they end up as first trimester abortions. Such pregnancies are either aborted spontaneously on their own i.e. one experiences bleeding with cramping pain in the abdomen and the pregnancy is expelled out of the body as it is not a viable pregnancy. Sometimes one misses abortion where the pregnancy is not growing as there is no heart beat resulting in shrunken pregnancy. The patient may have to face this situation after a sonography report after 12 weeks. This is called as missed abortion and they have to be removed surgically or medically.

First Trimester Spontaneous Abortions

Out of 100 women who conceive 15 % will end up with an abortion. It is not that uncommon. It is important to know the reason for the cause. The implicating defect is chromosomal/genetic defect leading to the pregnancy not growing and resulting in abortion. Genetic defects happens when the sperm and egg meet genetic interchange happen between the nuclei and if wrong genetic makeup-up is been formed in the growing embryo then the women’s body will recognise as an abnormal pregnancy and stops it growth.

This is natures way of selecting a good pregnancy, 15% of them are generally not good, hence it is aborted. Having one first trimester loss is not a sign of worry as it is mostly due to chromosomal defects and hopefully things can get better next. It is good to have an early indication than having to abort after 12 or 13, 14 weeks. Such cases of first trimester spontaneous abortions are mostly due to chromosomal defects and it ends at that.

Next Pregnancy

Next question one asks about is the chances of similar results, in next pregnancy, to results, that of previous pregnancy.

In the next pregnancy the chances of having repeated abortion do not rise about 15%. It has the same risk as last time when you were in pregnancy.

If a person unfortunately lands into abortion in the next pregnancy ie 2 abortions in a row or 2 or more abortions consecutively, in that case, one has to investigate further to find any other cause.

Talking about recurring pregnancy loss classically defined as  2 or 3 recurring  abortions happening consecutively, in that case, chromosomal defects take a back seat and what comes foremost are immunological defects (coagulation), anatomical defects or some hormonal defects.

Immunological defects happen when pregnancy triggers a reaction and that reaction leads to immunological compromise of the pregnancy leading to not growing. It simple terms the pregnancy is acts as foreign to the women’s body and that can evoke the response. The most common IR seen is Antiphopholipid Antibody Syndrome. It can be done with a simple blood test. This test is given to women with recurring pregnancy loss. In this disorder the blood becomes become thick and does not pass through the placenta and the pregnancy stops growing. There is a treatment module for APLA syndrome and is easily treated by giving aspirin tablets and heparin injections in the next pregnancy when it occurs. There are more factors which are immunological and inherent that could be also responsible. There is a battery of blood test that can be done to find out such disorders. Asparin and heparin treatment may be offered. Around 50%-60% of recurring pregnancy loss cases are due to immunological defects.

Second important defect is Harmonal defect. In this case lack of pregnancy saving hormone called progesterone may not support the pregnancy.  Without testing too much patients are put on progesterone to continue with pregnancy. This tackles the hormonal defects in recurring pregnancy loss.

The third factor is anatomical defects in the uterus. If one has recurring pregnancy loss it is important to evaluate the uterine cavity. The uterine cavity is where the embryo implants and the foetus grows. If there are defects such as septum’s or adhesions, which alter uterine cavity, then it can also lead to a recurring pregnancy loss. Such defects can be detected by doing a most common and simplest thing called 3D sonography for the uterus. If anything suspected it can always be confirmed and treated by doing histroscopy. Treatment of uterine disorders or uterian cavity disorders  such as septum’s or synechia, with histroscopy, has given good results in cases where these were the causes for abortions.

Chromosomal defects or congenital factor in recurring abortions is taken into consideration after all the factor have been accounted for. If the pregnancy is abnormal, it will be abnormal once. But its general case of abnormal pregnancy of the parents have a carrier type or gene which when always leads to abnormal pregnancy after mating. This is a genetic sphere. A genetist needs to evaluate such cases. Karyotype of a couple is done and sent to the genetist to find possible dysfunction in the gene which is leading to recurring abortion. A very small percentage of patients, who do face with such dysfunction, can be offered treatment of in vitro fertilisation and pre implantation genetics. An embryo can be formed and tested before implanting it for good results.

Recurring pregnancy loss is very stressful for the women facing as it pushes her into an uncertainty mindset. According to statistics chances for a second loss after the first loss of pregnancy does not rise. Even after 2 abortions the chances of having repeated abortions is around 22%-25%. Even after 3 consecutive losses the chances of repeated loss is 30%-35%. It mean there is more than 50% chance even after 3 abortions even if one doesn’t see a doctor and chances that one lands with a health pregnancy.

Recurring pregnancy loss is a stressful thing but we proper approach and investigation and treatment many of these cases can betrayed and saved. When the cause is determined and treated 80% of the cases will have a good result. Afcourse there will  always be around 10%-15% cases which will have unexplained reasons for the loss. But with further treatment and a different approach its hopeful those cases will also give good results.
