What Are the Common Causes of Miscarriage?

how Common Causes of Miscarriage Women have the ability to bring new life into the world, but there is always the risk of something going wrong. The worst scenario is a miscarriage, which involves losing a fetus before the 20th week of pregnancy. Going through this pain is challenging for women who experience a miscarriage.

Analysis shows that over 80% of miscarriages occur in the first trimester and can emotionally devastate the expecting parents. According to an NGO report, 10 to 15% of all confirmed pregnancies result in a miscarriage.

What is a Miscarriage?

The term ‘miscarriage’ describes the process that occurs during the first 20 weeks of pregnancy.

  • Early miscarriage: A miscarriage that occurs during the first trimester, between weeks 1 and 12, is called an early miscarriage.
  • Late miscarriage: A late miscarriage refers to a miscarriage that takes place during the second trimester, between weeks 13 and 20.
  • Stillbirth vs. Miscarriage: However, the term ‘stillbirth’ refers to the loss of a fetus after the 20th week.

Common Causes of Miscarriage

1. Chromosomal Abnormalities

Not all male and female gametes are normal, and conceiving from these abnormal gametes is also abnormal. When this miscarried fetus was scientifically studied, it was found that the fetus is genetically grossly abnormal. So, it’s Mother Nature’s way to discard and can’t conceive these pregnancies from growing further. 

2. Thyroid Disorders

If it is high or low, the thyroid also leads to a problem in conceiving a baby or infertility and recurrent miscarriages. The study shows that where a woman’s thyroid function is low, her body will try to compensate by developing hormones that suppress ovulation. Still, conversely, a thyroid produces many hormones that can interfere with estrogen ability and make the situation unfavorable for the uterus to implant or abnormal uterine bleeding.

3. Lifestyle Factors

On pregnancy days, fruits and other habits will be closely monitored. The pregnant woman should avoid pineapples, eggs, papaya, aloe Vera, sesame seed, drumstick tree, soft drink, and many more that cause bleeding, cervix dilation, uterine contractions, and many others that occur from miscarriage or abortion. 

4. Previous Abortions & Miscarriages

If a woman previously has intentional abortions, there are chances that they are at higher risk of miscarriage in the future. The intended miscarriage results in the cervix becoming incompetent, irritable, and sensitive. The female body cannot maintain the proper hormones required to support a healthy pregnancy. 

5. Infections & Medical Conditions

In early pregnancy, miscarriage occurs due to an imbalance in diabetes, thyroid, and high fever. Therefore, before planning for pregnancy, it is advisable to check your health status. Obesity is also another cause of miscarriage, and it occurs when BMI is high.
