What Are the Common Causes of Miscarriage? Understanding Early Pregnancy Loss

Many people wonder about the causes of a miscarriage. Understanding why miscarriages happen can help ease worry and confusion. In this blog, we will explain the risk factors for miscarriage and discuss the most common causes of miscarriage. We will also clear up some myths and share when it is important to seek medical advice. Knowing the facts can help you feel more informed and supported during a difficult time.

What is a Miscarriage?

A miscarriage is when a pregnancy ends on its own before 20 weeks. Most miscarriages happen in the first trimester, which is the first 12 weeks of pregnancy. Although it is common, it can be very upsetting. However, it is important to know that most women who have a miscarriage go on to have healthy pregnancies in the future. According to the Centers for Disease Control and Prevention (CDC), about 10 to 20 percent of known pregnancies end in miscarriage.

Main Causes of a Miscarriage

There are several reasons why a miscarriage may happen. Often, it is not caused by anything the mother did or did not do. Here are the main causes:

  • Chromosome problems: Most miscarriages are due to problems with the baby’s chromosomes. Chromosomes carry genes, and if there are too many or too few, the pregnancy may not develop normally.
  • Health conditions: Some health issues in the mother, such as uncontrolled diabetes or thyroid disease, can increase the risk.
  • Infections: Certain infections, like rubella or listeria, can sometimes lead to miscarriage.
  • Problems with the uterus or cervix: Issues like a weak cervix or abnormal shape of the uterus may play a role.
  • Hormone imbalances: Low levels of certain hormones can sometimes cause problems with pregnancy.

    • According to the World Health Organization (WHO), most miscarriages are not preventable and happen because of genetic or health reasons.

    Risk Factors That Increase Miscarriage Chances

    Some things can make a miscarriage more likely. But having one or more risk factors does not mean you will have a miscarriage. Here are some common risk factors:

  • Age: Women over 35 have a higher risk.
  • Previous miscarriages: Having had one or more miscarriages before can increase the risk.
  • Chronic health problems: Conditions like high blood pressure or autoimmune diseases can play a role.
  • Smoking, alcohol, or drug use: These can raise the risk of miscarriage.
  • Being underweight or overweight: Both can affect pregnancy health.
  • Severe infections or trauma: These can sometimes lead to miscarriage.

    • Still, many women with these risk factors have healthy pregnancies. It is always best to talk to your doctor about your own risks.

    Myths and Facts About Miscarriage Causes

    There are many myths about what causes a miscarriage. Let’s look at some facts:

  • Myth: Lifting heavy objects or stress always causes miscarriage.
  • Fact: Normal daily activities and mild stress do not usually cause miscarriage.
  • Myth: Using birth control before pregnancy increases risk.
  • Fact: Birth control use before pregnancy does not cause miscarriage.
  • Myth: Having sex during pregnancy is unsafe.
  • Fact: Sex is safe for most women unless a doctor says otherwise.

    • According to the CDC, most miscarriages are not caused by something the mother did. It is important to avoid blame and seek support.

    When to Seek Medical Advice

    Sometimes, it is hard to know when to call a doctor. However, you should seek medical help if you notice:

  • Heavy bleeding or passing large clots
  • Severe pain or cramping
  • Fever or chills
  • Signs of infection, such as foul-smelling discharge

    • Even if you are unsure, it is always better to check with a healthcare provider. Early care can help protect your health and well-being.
