Imagine the joy of discovering you are expecting, only to have that excitement suddenly taken away, miscarriage is a heartbreaking experience that many women face, yet it remains a topic shrouded in silence and misconceptions, but what really causes pregnancy loss, and is there anything that can be done to prevent it? In this article, we will uncover the real causes of miscarriage and how to reduce the risks, based on scientific facts and medical research.
What Causes Miscarriage?
Miscarriage, also known as spontaneous abortion, occurs when a pregnancy is lost before the 20th week, It’s more common than many realize, affecting about 10-20% of known pregnancies, while it can be a deeply emotional experience, it is often due to factors beyond one’s control.
1. Genetic or Chromosomal Abnormalities
The leading cause of miscarriage is chromosomal abnormalities in the embryo, when the sperm and egg combine, errors can occur in the genetic material, leading to a nonviable pregnancy, this happens naturally and is usually not preventable.
2. Hormonal Imbalances
Certain hormonal conditions, such as low progesterone levels or polycystic ovary syndrome (PCOS) can prevent a pregnancy from progressing. Women with irregular menstrual cycles or untreated hormonal disorders may be at higher risk.
3. Infections
Some infections can interfere with pregnancy and lead to miscarriage, these include.
-
Bacterial Vaginosis (BV)
-
Listeria infection (from contaminated food)
-
Sexually transmitted infections (STIs) like syphilis or chlamydia
-
Rubella (German measles)
4. Underlying Health Conditions
Chronic diseases such as diabetes, thyroid disorders, high blood pressure, and autoimmune diseases (like lupus or antiphospholipid syndrome) can increase miscarriage risk if not managed properly.
5. Uterine or Cervical Problems
Certain structural abnormalities in the uterus can make it difficult for a pregnancy to continue, these include.
-
Fibroids (non-cancerous growths in the uterus)
-
Incompetent cervix (a weakened cervix that opens too early in pregnancy)
-
Uterine septum (a division in the uterus that restricts space for the baby to grow)

7. Physical Trauma or Injury
Although minor falls or bumps do not usually cause miscarriage, severe physical trauma can increase the risk, pregnant women should take precautions to avoid accidents or high-impact activities.
8. High Levels of Stress
Chronic stress can elevate cortisol levels, which may affect hormone balance and pregnancy health, while stress alone does not directly cause miscarriage, it can contribute to other risk factors.
