Abdominoplasty with or without liposuction is not a treatment for obesity. Therefore, if you are planning to lose weight, you should do so before considering these procedures.
There is a limit to the amount of excess skin we can remove from your tummy. For example, if you have stretch marks extending above your tummy button, it is unlikely that we will be able to remove them during surgery. The operation will not restore your skin's elasticity, however, it will make it tighter. Over time, the skin may relax again to a certain extent. There is also a limit to how much we can tighten the skin and muscle, and it's unlikely your tummy will be completely flat.
If you have a thick abdominal wall, you may benefit from a secondary liposuction procedure performed several months after the abdominoplasty.
