For women planning a pregnancy, a preconception medical check-up is important for assessing the mother's health and preparing for a healthy pregnancy. A comprehensive evaluation before pregnancy can help identify previously undiagnosed health conditions and reduce potential risks during pregnancy as much as possible. During a preconception check-up, the expectant mother's overall health, medical history, current medications, previous surgeries, and past pregnancy history are evaluated. When necessary, blood tests, vitamin and mineral levels, and screening for certain infections may be performed. Managing chronic health conditions before pregnancy is also important for the health of both mother and baby. It is also important to consult a doctor regarding folic acid supplementation during this period. Folic acid is an essential vitamin for the development of the baby's brain and spinal cord, and supplementation may be recommended before conception. In addition, personalized recommendations may be provided regarding nutrition, maintaining a healthy weight, smoking and alcohol use, vaccinations, and lifestyle. Family history of inherited conditions and any complications experienced during previous pregnancies may also be reviewed, with additional evaluations planned when necessary. In summary, a preconception medical check-up is an important step toward starting a pregnancy in a healthy, informed, and safe manner. Women planning to become pregnant are encouraged to consult an obstetrics and gynecology specialist before conception to develop a pregnancy preparation plan tailored to their individual health needs.
