Miscarriage
Overview
Causes
In some people, the cause is not known. In others, it may happen due to:
- Problems in the chromosomes (common cause)
- Abnormal structure or issues in the uterine tract, such as fibroids
- Problem with hormones, such as not having enough hormone (progesterone) to support pregnancy
- Immune system-related problems, such as blood-clotting problems or rejection of the fetus
- Trauma
Risk Factors
This problem is more common in people 35 years of age and older. Other things that may raise the risk are:
- Infection
- Smoking, drinking alcohol, or using drugs during pregnancy
- Taking certain medicines
- Exposure to certain toxins in the environment
- Problems with the immune system, such as systemic lupus erythematosus
- High-dose radiation therapy on the ovaries, uterus, or the pituitary gland during childhood cancer treatment
SymptomsandDiagnosis
Symptoms
Problems may be:
- Vaginal bleeding or pink or brown discharge
- Cramping
- Passing the fetus, placenta, and surrounding tissues through the vagina
- Fever
Treatments
Treatment
Early or first trimester miscarriages may only need observation. Medicine may be needed if there is heavy bleeding or cramping.
A dilation and evacuation (D&E) may be needed if all tissue does not pass through the vagina. The doctor will remove remaining tissue.
