During confinement, the body weight will gradually decrease, generally around 8~ 12 kg, which also varies from person to person. When the fetus, placenta and amniotic fluid are discharged together after delivery, the weight of pregnant women will be reduced by about 9~ 1 1 kg, and the body will feel very light, even a little weak, and it is necessary to supplement a lot of water and nutrition. At this time, the weight will not return to the weight that was not pregnant before. If some people eat more high-protein or high-calorie food during confinement, they will be overnourished and have less activity, which will easily lead to the same weight as when they were pregnant. There are still some people who eat too much high-protein food because of breastfeeding, and they will still gain weight. Most women gain 3 to 5 kilograms, so the weight loss during confinement is not absolute. However, as breastfeeding continues, staying up late will consume and the weight will slowly drop. By weaning, the body weight will drop 10 to 15 kg.
