I am 36 years old, mother of 4.  After all my pregnancies, my stomach was just not the same, after carrying twins, it was never going to be the same.  I have wanted a tummy tuck for 5+ years.  For me this was not a weight loss procedure.  I am 5'5 and hover around 150lb, size 6/8.  This was procedure was so I could feel comfortable with my reflection again.  I had stretch marks, a frown of a belly button, and and extra pouch of a belly I was always trying to hide or tuck in the right pair of pants.  I finally took the plunge and scheduled my surgery.  2 week post now and I am feeling great.  The first week was rough, but at thins point I almost feel like I could go to the gym.  Images may be added later, as I am still healing 2 weeks post op.

I am 4 weeks post surgery and feel great.  Overall 90% normal.  Lower swelling still exists, but I feel like I can exercise and do just about everything I could before.  If you are considering a tummy tuck, I recommend several weeks of exercise first to help strengthen your core, it'll only help in your recovery.
