Prevention:

Some studies show that women who get prenatal care have better pregnancy outcomes, for themselves and their babies. Early and complete prenatal care reduces the risk of miscarriage.

It is better to find and treat health problems before you get pregnant than to wait until you're already pregnant. Avoiding environmental hazards such as x-rays and infectious diseases also decreases the risk of miscarriage in early pregnancy.

Spontaneous abortion is not preventable if the fetus dies. In fact, it is important for the uterus to expel all of its contents in such cases. A missed abortion occurs when a dead fetus is not expelled from the uterus. When only part of the dead fetus is expelled, it is called an incomplete abortion.
