How long do the effects of abdominoplasty last?

The effects of abdominoplasty last a long, long time! Just ask around for anyone who's had two tummy tucks. I've never heard of that, and that is because unless you do put on a very big amount of weight after the surgery the effects are meant to last a lifetime. This does not mean your tummy will always look the same, you will still age and change, but the effects do not "wear off" only for you to "revert to your previous abdomen". You will always be firmer and flatter than you would have been without the abdominoplasty. 

Go for it I say!

Public service announcement: A tummy tuck won't magically fix all your problems. If you do not change your lifestyle, the effects of tummy tuck surgery won't be permanent at all. 

You can see a tummy tuck as a way to bridge the gap between what your body can achieve with exercise and diet and your ideal body. It gives you a jump start if you like, to lay the foundation for a healthy lifestyle. That is not to say that an unhealthy lifestyle is what causes the need for tummy tucks. It isn't. It's mostly for moms and people who've lost a lot of weight. So it's about getting back into a permanently healthy lifestyle. 

You still need to do the work to keep it that way though!
