The majority of women gain too much or too little weight during pregnancy, putting both mothers and babies at an increased risk for complications, a review of past studies suggests.

Researchers examined data from 23 studies covering a total of more than 1.3 million pregnancies and found 47 percent of the time women gained more weight than recommended by the Institute of Medicine (IOM)—about 25 to 35 pounds for people who start out pregnancy at a normal weight. Another 23 percent of the time, women didn’t gain enough weight.
