Weight Gain During Pregnancy
In May 2009, The Institute of Medicine (IOM) made changes to the guidelines concerning pregnancy weight gain. The last recommendations had been released in 1990 and more research has been conducted on childbearing. Taking into consideration the demographics of the current childbearing woman, the IOM made their new guidelines using the World Health Organization’s (WHO) body mass index (BMI) as the starting point. These new guidelines give women a clear range of what a healthy weight gain looks like, in order to help them avoid pregnancy complications such as gestational diabetes, preeclampsia, and cesarean delivery.
