Miscarriage, also known as spontaneous abortion, is a pregnancy that ends on its own before the 20th week. It's a common experience for many women, with about 10-20% of known pregnancies ending in miscarriage. While it can be a difficult and emotional experience, understanding what a miscarriage is and its causes can help women better cope with the situation.
A miscarriage can occur for a variety of reasons, and in many cases, the exact cause is not known. However, research has identified several risk factors that can increase a woman's chances of experiencing a miscarriage. These risk factors include advanced maternal age, a history of previous miscarriages, and certain medical conditions such as diabetes or thyroid disease.
What is a Miscarriage?
A miscarriage is the loss of a pregnancy before the 20th week. This can occur at any time during the first 20 weeks of pregnancy, but it's most common during the first trimester. A miscarriage can be a complete or incomplete miscarriage. In a complete miscarriage, the entire pregnancy is expelled from the body, while in an incomplete miscarriage, some tissue remains in the uterus.
Types of Miscarriage
There are several types of miscarriage, including:
- Threatened miscarriage: This occurs when a woman experiences bleeding or spotting during pregnancy, but the cervix is still closed.
- Imminent miscarriage: This occurs when a woman experiences bleeding or spotting, and the cervix is open.
- Inevitable miscarriage: This occurs when a woman experiences bleeding or spotting, and the cervix is open, but the pregnancy tissue has not yet been expelled.
- Incomplete miscarriage: This occurs when some pregnancy tissue is expelled, but some remains in the uterus.
- Complete miscarriage: This occurs when the entire pregnancy tissue is expelled from the uterus.
Causes of Miscarriage
Miscarriage can occur for a variety of reasons, including:
| Cause | Description |
|---|---|
| Chromosomal abnormalities | Abnormalities in the chromosomes of the fetus can cause a miscarriage. |
| Hormonal imbalance | Hormonal imbalances, such as low progesterone levels, can cause a miscarriage. |
| Uterine abnormalities | Abnormalities in the shape or structure of the uterus can cause a miscarriage. |
| Infections | Infections, such as bacterial vaginosis or chorioamnionitis, can cause a miscarriage. |
| Autoimmune disorders | Autoimmune disorders, such as lupus or rheumatoid arthritis, can cause a miscarriage. |
