Frequently Asked Questions
Why does recommended weight gain depend on pre-pregnancy BMI?
Guidelines (based on Institute of Medicine recommendations) suggest lower total weight gain for those starting pregnancy at a higher BMI and higher total gain for those starting underweight, aiming for healthy outcomes for both parent and baby.
Is weight gain linear throughout pregnancy?
No — most guidelines suggest slower gain in the first trimester (around 1-2 kg total) with a more steady, faster rate in the second and third trimesters, so this calculator's straight-line estimate is a simplification.
Should I strictly follow these numbers?
These are general population guidelines — always follow your own healthcare provider's specific guidance, since individual factors (multiples pregnancy, health conditions) can significantly change appropriate weight gain targets.
