It is said that pregnancy is a matter of chance. The risk of miscarriage in the first three months is 75 percent and in the second trimester it is 3 percent. Most women miscarry their babies in the first three months, hence these are the crucial months of pregnancy that women must be careful about.

Now coming to the age of a woman, the risk of miscarriage after the age 30 is 12 percent, after age 35 it is 39 percent and after 40 years of age the risk of miscarriage is 60 percent. Another surprising thing about miscarriages is that about 5,00,000 pregnancies end up in a miscarriage worldwide.

It is also true that 1 in 4 pregnancies end up in a miscarriage. This shows that the rate of miscarriage is high. The number has increased in the recent years due to many modern-day factors. Some women may even miscarry before they even know that they are pregnant.

Hence, let's know the reasons of a miscarriage, so that it may help you in diagnosis. Miscarriage can also occur due to many reasons that are mentioned in the article below.


Poor Quality Of Eggs And Sperms

An egg or sperm can not be fully developed due to poor nutrition or advanced age. We do not take enough of some minerals such as zinc, selenium, and other minerals and vitamins in our diet, resulting in low quality of eggs and sperms. A woman can even miscarry if a sperm is not of a good quality. Therefore, focus on your diet.



If you are having an underactive thyroid gland, this means that the thyroid hormones are not being secreted in adequate amounts in the body. This can cause recurrent miscarriages and even pose a problem in conceiving.


High Blood Sugar

In some pregnant women, the blood sugar gets abnormally high, which they may not be aware of. The increased blood sugar level can cause a miscarriage. Hence, have a check on your blood sugar level during your pregnancy to avoid any complications and a miscarriage.


Immunity-related Problems

Sometimes, the reason for a miscarriage can be very complicated. This means there is some problem with certain enzymes known as phospholipid enzymes. In this case, some tiny blood clots may be formed in the blood of the mother that cause death of the foetus. To diagnose this, you need a blood test to be done (anti-phospholipid test).


Chromosomal Abnormality

In some women, there is a condition known as a balanced translocation. A rare condition though but can cause recurrent miscarriages. In this condition, some part of a chromosome can be split and get attached to the other chromosomes. This can cause abnormality in the egg, and thus result in a miscarriage. A woman has to keep on trying in this case and chances are that she may get a healthy pregnancy too.


Harmful Habits

If a woman has some addictions such as smoking, drinking alcohol, etc, the risk of a miscarriage can be high. Eating unhealthy foods that are infectious can also cause miscarriages.



Any mental or physical stress that can make a person to go in a state of shock can trigger a miscarriage. In a physical trauma, a mother may lose her baby and in high mental stress also the stress hormones can attack the uterus to cause a miscarriage.
