Pregnancy Weight Gain Patterns and Guidelines

First Trimester Weight Gain

  • Evidence suggests that many women may experience a significant amount of weight gain before their first antenatal visit, and this early weight gain is associated with overall high gestational weight gain and potentially adverse pregnancy outcomes 1

Healthcare Professional Considerations

  • Healthcare professionals should be adequately trained to discuss gestational weight gain with pregnant women, as many lack confidence or knowledge regarding current guidelines 2, 3
  • It's essential for healthcare providers to inform women about weight gain expectations early in pregnancy, as many women report not being aware of gestational weight gain guidelines or associated risks 3
  • Women expect their maternity care providers to inform them of everything significant in pregnancy, including appropriate weight gain 3

Monitoring Recommendations

  • Regular weight monitoring should begin at the first antenatal visit to establish baseline measurements 4
  • Weight gain monitoring should be tailored to the woman's pre-pregnancy BMI, pregnancy situation (e.g., twins), and age 2
