I'm young male in my early 20's and I'm generally in the normal weight, I workout and exercise a lot. I used to be overweight in highschool but I managed to lose all the excessive weight in college, however, I was never able to get rid of the love handles and lower abs fat (and sagging skin). I decided to have a tummy tuck and end my long battle with my love handles. I had the surgery 7 months ago. I can safely say it was well worth it.
I will be frank and say that the first week post op was very tough on me. The drain tubes were very uncomfortable and the painkillers gave me the worst constipation ever. But once that week passed, there was no doubt in my mind that I have made the right decision. My surgeon was really skilled, he did an awesome job on positioning the incision well below the waist line. My stomach is completely flat now and the results met my expectations. There was minimal swelling in my case - which is rare form what I read online - and the credit for this goes to the skills of my surgeon. I have also suffered almost no pain during the recovery time. 7 months after the surgery, I'm still very satisfied with the results and recommend it. I still have a visible scar, it has faded to some degree but I think it can get better.
My advice to you is do your research, it's very important that you pick the right surgeon, I have read some stories about the tummy tuck that were nothing like my experience (particularly the swelling part), so do your research!
