Exposure to these by either partner can make it more difficult to become pregnant and can harm the fetus. Ask your parents if there is a family history of problem pregnancies or birth defects. If you have reason to be concerned about a genetic disorder or inherited disease, you may want to consult a genetic counselor. For Women Only Try to achieve your normal weight before attempting to conceive. It's important not to be underweight or overweight during pregnancy.
Overweight women are more likely to develop high blood pressure or diabetes during pregnancy.
Don't diet during pregnancy, however, or while you are trying to become pregnant. Make sure to get enough of the B vitamin folic acid on a daily basis. Studies have shown that birth defects of the spine and brain, such as spina bifida and anencephaly, can occur if the mother does not get sufficient folio acid during the first few weeks of her pregnancy. Discuss it with your doctor. If you have diabetes, make sure it is being treated.
