Mischance of Miscarriage


The journey of fertility is a long and winding road which brings about much anxiety and stress for many couples trying to conceive. Fertility has its challenges with trying to conceive in the first place along with maintaining pregnancy. It is fair to say that for most couples that once pregnancy has been achieved, stress and anxiety continues to increase, particularly in the first trimester.

Sadly, the probability of pregnancies ending in miscarriage in the UK is estimated around 1 in 4, with most miscarriages happening in the first trimester. In this trimester, it is considered that around 80% of miscarriages are usually caused by chromosomal abnormalities, which understandably causes emotional devastation when you have been trying to conceive, no matter how long it has taken to fall pregnant.

With a high rate of 1 in 4 women suffering a miscarriage at some time in their lives, it is encouraging to know that most couples who experience this loss go on to having successful pregnancies thereafter, but what can you do to prevent miscarriage? or what are your chances of maintaining pregnancy if have been diagnosed with recurrent miscarriage? I see many couples with this condition and know only to well the mental and physical affects that miscarriages can bring with their need to understand why this has happened.

Although very difficult to take a rational approach of understanding after a miscarriage due to the emotions associated, I think it is important to have some clarity to the reasons and causes of miscarriage and most of all what you can do to prevent miscarriage prior to becoming pregnant.

Most common reasons for miscarriage

Once a miscarriage has happened, many ask themselves what could have been done to stop the miscarriage during its process, but the truth of the matter is that once a miscarriage starts there is nothing anyone can do to prevent it, as its nature’s way indicating something is wrong with the developing pregnancy and baby.

Our body provides nutrients to the developing baby during pregnancy to help with its normal development, and one of the main causes of miscarriage during the first trimester is that there is an abnormal development.

Genetic issues

Half of miscarriages usually occur because of chromosome issues. Chromosomes carry the DNA and genetic code for cells to function which errors can occur randomly during the rapid division of foetal cells and as a result of damaged sperm or egg cells. At the time, most early miscarriages cannot always be explained in depth and unless a biopsy is taken it is difficult to the know the reason, which is why embryo testing can help. Pre-implantation genetic screening (PGS) or pre-implantation genetic diagnosis testing can be carried out to identify embryos that have chromosome issues or known genetic disorders for the prevention of miscarriage particularly for those with recurrent miscarriages or whom are carriers of specific chromosome and genetic illnesses.

However, some miscarriages can be identified and termed with the following causes,

Molar pregnancy happens when the father provides both sets of chromosomes, but there is no development of a foetus. Instead, there is an abnormal growth of the placenta.

Partial molar pregnancy is when the chromosomes from the mother remain; but the father also provides two sets of chromosomes. It is associated with placental abnormalities and growth of an abnormal foetus.

The intrauterine demise of the fetus is a formation of the embryo but it stops developing before there is a development of any symptoms of miscarriage.

Blighted ovum is where there is no formation of an embryo. This is one of the reasons for early miscarriage.
