Antenatal care involves regular checkups during pregnancy to monitor the health of the mother and baby. Checkups include exams, tests, and education on nutrition, exercise, hygiene, warning signs and avoiding risks. The goals are to prevent or treat complications, detect issues, and ensure healthy development. Women receive more frequent exams as their due date approaches, and are instructed on a nutritious diet, moderate exercise, adequate rest, hygienic practices, and when to seek medical help if problems arise.
