I just had a tummy tuck. How many dissolvable stitches are inside me, just approx?

Thank you for your question. How many and what kind of sutures are used varies from surgeon to surgeon. Also, sometimes suturing is performed at a single site and other times one long suture is used along the entire length of the incision. With all of these variables, it's impossible to guess how many dissolvable sutures your surgeon used. This is a great question for them.

Thanks for sharing your question. 
This is a typical question that as a surgeon you hardly pay attention to. The typical answer is to focus on the surgery and the outcome, and not count the minor steps to get there. A wild guess would be 70 cm incision. 1 stitch every 1-2 cm deep = 35subcuticular suture: x 2 with possibly 70 x 2 entrances and exits = 140Muscle approximation: 30 cm with 15 stitches= 15Grand total: 180 aprox.
Wishing you the best in your journey

It is imperative that you have a thorough examination by a board-certified surgeon. Only then, you may weight better the options to fix your current concerns.
