🤰 Pregnancy Weight Gain Calculator

Pregnancy weight gain recommendations are based on your pre-pregnancy BMI. According to WHO guidelines: Underweight (BMI < 18.5) should gain 12.5-18 kg, Normal weight (BMI 18.5-24.9) should gain 11.5-16 kg, Overweight (BMI 25-29.9) should gain 7-11.5 kg, Obese (BMI ≥ 30) should gain 5-9 kg. For twins, recommendations are typically 16-24 kg regardless of BMI.

Weight gain follows a pattern during pregnancy: First trimester: 0.5-2 kg total (minimal gain, sometimes weight loss due to morning sickness), Second trimester: Steady gain of about 0.5-0.7 kg per week, Third trimester: Continued gain of about 0.5-0.7 kg per week, with the most rapid growth occurring in the final months. The majority of weight is gained after week 20.

Inadequate weight gain can increase risks of preterm birth and low birth weight. Excessive weight gain can increase risks of gestational diabetes, high blood pressure, cesarean delivery, and large birth weight babies. Always consult with your healthcare provider if your weight gain falls outside recommended ranges. They can provide personalized guidance based on your specific health situation.

Yes, appropriate weight gain is crucial for baby's development. Adequate weight gain supports proper fetal growth, organ development, and nutrient supply. Both insufficient and excessive weight gain can impact baby's health. Studies show appropriate weight gain reduces risks of preterm birth, low birth weight, and childhood obesity while supporting optimal brain development.

The WHO recommends gradual weight loss after pregnancy. Most women lose about 6 kg immediately after delivery (baby, placenta, amniotic fluid). The remaining weight should be lost gradually over 6-12 months. Rapid weight loss can affect milk production for breastfeeding mothers. A healthy rate is 0.5-1 kg per week through balanced nutrition and appropriate physical activity when cleared by your healthcare provider.
