孕期体重增长计算器
孕期应增加多少体重主要取决于您的孕前 BMI。本计算器采用针对单胎妊娠广泛使用的美国医学研究所（IOM）2009 年指南：输入孕前体重和身高即可获得您的 BMI 分类和建议总增重，再添加当前孕周和体重，即可查看到目前为止的建议范围以及您是否处于合理进度。这仅为一般指导，您的医生或助产士可能会建议不同的目标。
基于针对单胎妊娠的 IOM 2009 指南。仅供一般参考，请始终遵循您的医生或助产士的建议。
常见问题
- What is a pregnancy weight gain calculator?
- It shows your recommended total and weekly weight-gain range during pregnancy based on your pre-pregnancy BMI, following the Institute of Medicine (IOM) guidelines. It helps you check whether your gain is on track for a healthy pregnancy.
- How is healthy pregnancy weight gain determined?
- Recommendations depend on your pre-pregnancy BMI category. Enter your starting weight and height, and the calculator applies the IOM ranges to give your total target plus the weekly pace expected in the second and third trimesters.
- How much weight should I gain during pregnancy?
- Under IOM guidelines, a woman who started at a normal BMI is advised to gain about 11.5 to 16 kg (25 to 35 lb) total. Underweight women are advised to gain more and overweight or obese women less, so your range is individualized.
