In principle, you can start using the lap band after normal delivery, the earlier you apply it, the better, but the mother can decide to start using the lap band according to their own situation. During pregnancy, the body of pregnant women will produce relaxin, which has the effect of relaxing the ligaments of pregnant women to maintain pregnancy. At the same time, after normal delivery, the vagina will continue to discharge malodorous fluid, the use of belly band after delivery can promote the discharge of malodorous fluid, help joints, ligaments and other recovery. If a fat pregnant woman has a thick abdominal fat layer, using a lap band immediately after delivery may cause the uterus to shift upward, thus affecting the recovery of the uterus, so such pregnant women can start using a lap band one month after delivery. The belly band is recommended to be taken off half an hour after meals, after urination, and before going to bed at night, and the binding strength should be moderate, too tight may lead to tissue edema, affecting digestion, and too loose binding is not conducive to fixing the pelvis.
