A Pregnancy Weight Gain Calculator is a quick and easy way to estimate the ideal amount of weight you should gain throughout pregnancy. It uses your Body Mass Index (BMI) before pregnancy and the number of weeks you are pregnant to calculate a healthy range.
While some weight gain is natural and necessary, too much or too little can lead to complications. This calculator helps you stay within the recommended range for a healthy pregnancy and safe delivery.
However, remember — these results serve as a guide. Always discuss your progress with your gynecologist in Coimbatore to receive advice tailored to your health and your baby’s growth.

| 25 - 29.9 | Overweight | 7 - 11.5 kg (15 - 25 lbs) |
