Miscarriage, also known as spontaneous abortion, is a pregnancy that ends on its own before the 20th week. It is a common occurrence, affecting up to 20% of known pregnancies. Understanding miscarriage by week can provide valuable insights into its causes, risks, and the support available for those affected.
The risk of miscarriage varies throughout pregnancy, with the highest risk during the first trimester. According to the American Pregnancy Association, the risk of miscarriage by week is as follows: 1-2 weeks (50-75%), 3-4 weeks (20-30%), 5-6 weeks (10-15%), 7-12 weeks (5-10%), and 13-20 weeks (less than 5%). These statistics highlight the importance of understanding miscarriage by week to better comprehend the risks and causes.
Causes of Miscarriage by Week
Miscarriage can be caused by a variety of factors, including chromosomal abnormalities, hormonal imbalances, infections, and uterine or cervical problems. The causes of miscarriage can vary depending on the gestational age.
First Trimester Miscarriage (Weeks 1-12)
During the first trimester, miscarriage is often caused by chromosomal abnormalities, such as Down syndrome or Edwards syndrome. Hormonal imbalances, particularly low progesterone levels, can also contribute to miscarriage during this period. Additionally, infections like Listeria or Toxoplasma can increase the risk of miscarriage.
| Cause | Percentage of Miscarriages |
|---|---|
| Chromosomal Abnormalities | 50-60% |
| Hormonal Imbalances | 20-30% |
| Infections | 5-10% |
