What are the Causes of Miscarriage?
Other causes of spontaneous abortions may be factors related to the mother's health. Miscarriage from these causes usually occurs later in pregnancy. They include-
Chronic diseases such as diabetes or high blood pressure
Problems with the immune system
Abnormalities of the uterus or cervix such as cervical incompetence, in which the cervix begins to dilate too early in pregnancy. This nearly always occurs in the second trimester (after 3 months).
Drugs, smoking or alcohol abuse
Exposure to environmental toxins
