What causes miscarriages, and how often are they in the first trimester?


A MISCARRIAGE is the term used when describing the loss of a baby during the first 24 weeks of pregnancy.

Sadly, they are far more common than many people assume.

And the experience can be emotionally devastating for both mum and dad.

But what exactly is a miscarriage, what are the signs and how regularly do they occur? Here’s all the information…

A miscarriage is the loss of a pregnancy during the first three months of pregnancy, with a “late miscarriage” defined by the charity Tommy’s as between 14 and 24 weeks.

There are many reasons why a miscarriage can occur, but the majority are not caused by anything a mother has done.

Most of the time a woman won’t find out why she had a miscarriage, which can make the ordeal more distressing.

In the first trimester of pregnancy, usually a miscarriage is the result of a problem with the unborn baby.

The NHS says a common cause is thought to be abnormal chromosomes in the foetus.

If a baby has not enough or too many chromosomes, a chance event, it will be unable to grow or develop properly.

In about two to five per cent of miscarriages, genetics are to blame if a partner has an abnormality in one of their chromosomes they are not aware of.

There could be a problem with the development of the placenta, starving the baby of blood and nutrients.

In the second trimester, a weak cervix, an infection or STI, the shape of the mother’s womb and PCOS and even food poisoning are all causes of miscarriage.

Tommy’s says  “there are several factors that may play a part in causing recurrent and late miscarriage”.

This includes blood clotting disorders, thyroid problems, cervical weaknesses and possibly immune cells zapping fertility.

Many women who miscarry go on to have successful pregnancies in the future.

But for those who have a late miscarriage, or recurrent ones, tests may be done to discover why.

Miscarriages are a lot more common than most people think, affecting one in eight pregnancies, the NHS says.

Many more miscarriages happen before a woman knows she is pregnant.

Recurring miscarriages, which are when three or more pregnancies are lost in a row, are less common, affecting one in 100 women.

Miscarriages become more common as women age. In women under 30, one in 10 pregnancies end in miscarriage, which raises to five in 10 in women over 45.

The most clear sign a woman is having a miscarriage is bleeding, varying from light spotting to heavy blood clots.

But bear in mind, some bleeding during the first three months of pregnancy is normal and does not necessarily mean a miscarriage – contact the… Brinkwire Brief News.
