Good health is important throughout life, not just during pregnancy. While many lifestyle factors including diet, exercise, smoking and alcohol consumption significantly influence pregnancy outcomes, a woman's health and her family's health history are very important also. During a pre-conception consultation with a physician, or when a woman initially suspects she is pregnant, the doctor will take a thorough medical history.

Vaccination History
Infectious diseases such as measles, mumps and rubella can seriously harm a developing fetus. The doctor will want to ensure immunity to these diseases. One acquires immunity through a previous exposure or vaccination against the disease. The doctor may take blood to test immunity. If the woman has never been vaccinated the doctor may suggest immunization. The American College of Obstetricians and Gynecologists recommends vaccination at least three months before becoming pregnant.

Sexually Transmitted Diseases
Sexually transmitted diseases (STDs) such as HIV/AIDS, Chlamydia, Gonorrhea, Genital Herpes, Genital Warts and Syphilis can affect a woman's ability to conceive and can significantly harm or even kill a developing baby. Women should be tested and treated for STDs prior to conception.

Family History - Medical History
The doctor will inquire about a woman's family history of illness. Certain diseases of particular importance include diabetes, hypertension (high blood pressure) and epilepsy. Women with a family history of these conditions or with a personal history of diabetes, hypertension or cardiovascular disease may require additional monitoring during pregnancy.
