For this reason, you are recommended to adopt other techniques if you want to avoid pregnancy. Most specialists believe that it’s better to wait 12-18 months after surgery before getting pregnant. The good news is that after the operation, there is much less risk of dealing with problems caused because of pregnancy and childbirth. Furthermore, kids born after the surgery are less at risk of being affected by obesity later. The reason is the activation of certain genes during fetal growth.
