It is not recommended to lose weight by confinement, because lactating women should ensure the quality of milk, have enough protein in their diet, and have balanced nutrition, so that children can enhance their resistance by eating breast milk; On the other hand, during the confinement period, the physiological function and organ function of the parturient are in the recovery stage, and some people will lose weight automatically if they don't lose weight. For example, if the uterus is enlarged, it will expand to the upper abdomen. At this stage, it will return to the size of the egg before pregnancy within 6 weeks, and when it returns to the pelvic cavity, the abdomen will not be so bloated; Moreover, the muscle elastic fibers in the abdomen gradually tighten; Also, the originally increased blood volume in the body can also be excreted through urine. In the process of this repair, some people will look thinner. However, proper exercise is still necessary, and we should not overwork. The amount of postpartum rehabilitation exercise should be gradual. The perineal wound will be very painful at first, and lochia may occur within three weeks. At this stage, do some simple Kegel exercises, stand at home and relax, contract the muscles of anus and pelvic floor for five seconds, and then relax. Repeating more than 20 times is daily exercise, which can maintain the strength of pelvic floor muscles and try not to let them relax.
