What is the Pregnancy Weight Gain Calculator & How does it work?
Pregnancy weight gain is an important aspect of maternal health and fetal development. The amount of weight a woman should gain during pregnancy depends on her pre-pregnancy BMI (Body Mass Index). According to the Institute of Medicine, women with a normal BMI (18.5-24.9) should aim for a total weight gain of 25 to 35 pounds (approximately 11.3 to 16 kg) over the course of their pregnancy.

BMI = Body Mass Index, Weight Gain = Recommended weight gain in pounds
Proper weight gain during pregnancy is crucial for the health of both the mother and the baby. It supports fetal growth and development, helps prevent complications such as gestational diabetes and pre-eclampsia, and ensures a healthy delivery.
