Some amount of weight gain is normal during pregnancy. But if you put on too much weight it is not good. A new study from Virginia Commonwealth University Institute in the US says that excessive gestational weight gain (GWG) is not only linked with the increased long-term maternal weight but it also has cumulative effect over multiple pregnancies. The Journal of Women’s Health published this study. According to researchers each pregnancy with ‘excessive GWG was associated with 64 per cent increase in the likelihood of obesity at midlife regardless of the race ethnicity number of pregnancies and physical activity levels’.
