Introduction
The Pregnancy Weight Gain Calculator is a valuable tool designed to help expectant mothers track their weight gain during pregnancy. Gaining the appropriate amount of weight is crucial for the health of both the mother and the developing baby.

Formula
Target Gain by week ≈ FirstTrimesterGain + WeeklyRate x (GestationalWeek - 13)
This formula calculates your target weight gain based on your pre-pregnancy BMI and the current week of pregnancy. 'FirstTrimesterGain' is the recommended weight gain during the first trimester, while 'WeeklyRate' varies according to your BMI category in the second and third trimesters. 'GestationalWeek' refers to your current week of pregnancy.
Example Calculation
Suppose a woman has a pre-pregnancy BMI of 24 and is currently at gestational week 28. First, she inputs her pre-pregnancy weight, and height, and the calculator computes her BMI category as normal. For the normal BMI category, the first trimester gain is approximately 1.5 kg, and the weekly gain rate is around 0.42 kg. Using the formula: Gain ≈ 1.5 kg + 0.42 kg/week x (28 - 13) = 1.5 + 0.42 x 15 = 7.8 kg. So, her target cumulative gain by week 28 is approximately 7.8 kg.
Understanding Your Results
The results indicate a target cumulative weight gain specific to the entered gestational week and pre-pregnancy BMI. If your calculated weight gain is below the recommended range, it may suggest undernutrition, while above the range could indicate excessive weight gain. It's essential to consult with a healthcare provider to discuss any necessary adjustments.
