A pregnancy weight calculator is a tool used to estimate appropriate weight gain during pregnancy based on pre-pregnancy weight and height. It typically provides a range of healthy weight gain and may offer week-by-week guidance. For example, a woman of average pre-pregnancy weight might be advised to gain between 25 and 35 pounds throughout her pregnancy.
Managing weight gain during pregnancy is vital for both maternal and fetal health. Appropriate weight gain reduces the risk of complications such as gestational diabetes, preeclampsia, and preterm birth. It also contributes to a healthier birth weight for the baby, reducing the likelihood of future health problems. While these tools have become increasingly accessible with the rise of online resources, the underlying principles of healthy weight gain during pregnancy have long been a focus of prenatal care.
