This can happen while a woman has neither menstrual periods nor any signs of pregnancy. Breasts may return to their pre-pregnancy state, or the woman may lose a few pounds. These procedures not only clear the uterus but also prevent infection. When incomplete miscarriage occurs later in pregnancy, the doctor may have to induce labor to remove the fetus. There are, however, steps you can take to reduce the risk of losing a pregnancy.
Smoking increases the risk of losing a genetically normal baby.
One study showed that women who smoked more than 10 cigarettes a day were about twice as likely to miscarry, regardless of their age. The risk of losing a pregnancy increases with the number of cigarettes a woman smokes. Don't drink alcoholic beverages. Avoid radiation and poisons. Exposure to high levels of radiation or toxic substances increases the risk of miscarriage.
