Hi and thanks for your question. You have probably figured out that because there are so many different answers, there is not one answer. Confusing right? There is a reason tummy tuck patients are bent at the waist after the procedure. This position mirrors the position the patient is in when the excess skin is measured, removed, and the incision repaired. How quickly they straighten up depends upon how quickly the skin stretches, allowing them to straighten up. Skin elasticity plays an important role here. Severe sun damaged skin (chronic sun tanners have this) takes the longest in my experience while the skin of massive weight loss patients tends to stretch the fastest. Remember, your goal for this procedure is to tighten skin that is lax, so the earlier you can straighten up without undue tension, the less tight the skin is going to be in the end. (Tension on the skin =bad, because it interfers with bloodflow) . I always tell my patients that " the good news is that your skin will eventually relax, but the bad news is ....that your skin will eventually relax!" Good luck, ask your surgeon for guidance, and give yourself time to recover At your own pace. In the end, You'll be glad you did!Joel A. Williams, M.D., F.A.C.S.
