Under normal circumstances during pregnancy, the weight gain of pregnant women is within the normal range of 15-25 pounds, and in the case of obese pregnant women, the weight gain should be controlled between 10-15 pounds. If you gain too much weight during pregnancy, it will increase the risk of pregnant women, which can easily cause gestational diabetes, gestational hypertension, and also easily lead to huge babies, which will have an impact on the later vaginal delivery. Therefore, it is not necessary to overeat or eat too much particularly nutritious food during pregnancy, just pay more attention to the diversity of the diet based on the usual diet. In addition, supplement calcium, iron, zinc and other trace elements on time, do not eat too much every day, and exercise properly during pregnancy to keep your weight under control.
