Miscarriages are a devastating and mentally challenging event for women and couples. They’re often not talked about at all, or if they are, usually quite a while after the event. This can leave women feeling isolated, alone, depressed and often as a failure.
However this is not true and understanding why miscarriages occur is an important step in acceptance and in finding a solution.
Just to note, in this blog we have used the term miscarriage throughout for ease, however when a pregnancy ends before 24 weeks, it is know as a miscarriage, and for post 24 weeks it is considered a stillbirth.
So firstly, what causes a miscarriage?
For a baby to successfully reach full term there are a number of carefully orchestrated biological steps that must take place.
Fertilisation of an embryo between two healthy cells (the female egg and the male sperm)
Successful implantation of the developing embryo to the uterine wall
Adaptation of maternal physiology to accept the foetus, for example reduce immune response to avoid rejection of the foetus.
The mother’s ability to grow a placenta that can meet the foetus’ nutritional and physical demands
The ability of the uterus and cervix to hold the pregnancy
Appropriate growth of the foetus and timing of birth. This includes DNA and cell replication avoiding any congenital defects
At any one of these stages there is a risk, meaning there are many possibilities why a miscarriage can occur.
Reasons for miscarriage:
Anatomical/Structural: Heart shaped uterus, incompetent cervix, uterine fibroids (10-15% of cases)
Genetic defects: This applies to either the egg or sperm or both. Missing chromosomes or damaged DNA account for 60-80% of genetic defect miscarriages
Blood clotting factors: Blood too thick or clotting
Immune system issues: Body mistakes pregnancy as a foreign object and rejects the pregnancy
Hormone imbalance: Low progesterone, hyper/hypothyroidism, diabetes, PCOS, high prolactin
Environmental: Such as exposure to chemicals, x-rays or toxins, or drug use
Weight: Being extremely under or over weight can also cause the pregnancy to be rejected. A safe BMI range is 20-25
Infections: Rubella, STI’s, etc
Unexplained reasons, accidence or violence
Mental health: Anxiety, depression and PTS is strongly associated with miscarriage
1 in 4 pregnancies result in a miscarriage
1 in 100 women experience recurrent pregnancy loss
The risk of recurrent miscarriages unfortunately increases as women get older:
By 35 years of age it’s 9-12%
By 40, it’s 50%
Repeat pregnancy loss is diagnosed after 3 or more miscarriages are experienced.
What can the timing of a miscarriage reveal?
Before 4 weeks: Likely a thrombotic event, issue with the uterine lining, lack of progesterone, genetic defect within the embryo from either the egg or sperm, or oxidative stress
4-8 weeks: Majority of causes are genetic defaults as the embryo divides rapidly
After 8 weeks: At this stage, it is more likely a cause other than genetic, as the majority of chromosomal abnormalities are lost earlier.
What do you do if you think you’re having a miscarriage?
This depends on your stage in the pregnancy. If it’s within 4 weeks, you will likely mistake this as your period and can therefore wait for the tissue to past naturally.
If you know you’re pregnant, recommend contacting your GP or midwife. Again, depending on how far along the pregnancy is you will likely be advised the following:
Wait for the tissue to pass naturally
Medical management – a pessary is inserted to encourage the body to pass tissue
Surgical management with a suction device – this is called a Dilation & Curettage (D&C)
As with any medical concerns, if you’re concerned, worried or your symptoms are not dissipating contact or visit your GP or hospital immediately.
Support after a miscarriage is available
1 in 3 women who have suffered a pregnancy loss suffer post traumatic stress disorder. If you, a loved one, a friend or family member has suffered a miscarriage there are some great resources and charities that provide emotional support and help with grief including Petals, The Miscarriage Association and Tommy’s.
