Frequently Asked Questions – Weight Gain Tracking

How often should I track my weight during pregnancy?

Weigh yourself once a week at the same time of day, preferably in the morning after using the bathroom. Daily weighing can be misleading due to normal fluctuations from water retention and food intake.

What if I’m gaining weight too quickly or slowly?

Consult your healthcare provider if you’re consistently above or below recommended ranges. They can assess your individual situation and adjust recommendations. Small weekly variations are normal, but consistent patterns need attention.

Why is weight gain different for each trimester?

First trimester weight gain is minimal (1-4 lbs) due to morning sickness and small fetal size. Second and third trimesters require steady gain (1-2 lbs/week) to support rapid fetal growth and maternal changes.

Can I lose weight during pregnancy if I’m overweight?

Weight loss during pregnancy is generally not recommended, even for overweight women. Focus on healthy eating and appropriate exercise. Some women with obesity may maintain weight or have minimal gain under medical supervision.

What factors can affect pregnancy weight gain?

Factors include pre-pregnancy BMI, multiple pregnancies, maternal age, activity level, morning sickness, food cravings, water retention, and medical conditions. Your healthcare provider considers these when setting individual targets.
