I am 33 years old, in very good shape. I am a runner and I workout 6 days a week. I have two children 14 & 11.... Recently I had mini abdominoplasty. I am healed now. I am however concerned, because since I can remember, if I stand up and relax my abs, my belly looks as though I am 6-7 months pregnant! If I tighten up my abs, you can see my six pack. I am hardly fat, and being that I had that surgery I would think my belly would be flat as a board even when I am not tightening up the abs. Is there something wrong with my intestines? I am embarressed to show my doctor my belly. You would never know it by looking at me. I am very scared as it freaks me out. I spend a lot of money of a surgery because I thought it was my abs (loose from having kids).... But the Dr. Tighten up my abs, and pulled my skin so tight....What could this be?
