Understanding Miscarriage: Possible Causes
Miscarriage is common, but finding its cause may not be easy. If a cause can be found, it’s likely to be a problem with the baby or the uterus or cervix. Other factors cause miscarriage, but they're less common.
Problems with the baby
Either of these problems with the baby can cause a miscarriage:

-
The uterus may be divided (have a septum). Or it may have growths such as fibroids or adhesions.
-
The lining of the uterus may be too thin for the fertilized egg to grow in.
-
The cervix may be too weak to support the weight of a growing baby.
Other factors
Any of these problems can cause a miscarriage:
-
A serious illness, such as uncontrolled diabetes.
-
A bad injury, such as from a car accident.
-
Contact with toxins or radiation.
