Will a c-section be hard after a tummy tuck?

Congrats on your upcoming baby ! Its likely that the contouring improvements you gained from TT surgery will be lost after your pregnancy- but these issues can be addressed 12-16 months post partum. Your OB will likely do a typical Cesarean approach using a low pelvic scar. The fact that you have had a TT should not complicate this important operation.

Despite your prior tummy tuck, a planned C-section will not be problem for your OB at the time you are due. You may wish to discuss your concerns with your OB so you can anticipate the incision used. Most will use a low transverse incision called a phanenstiel incision which can be approached through the tummy tuck scar, though based on your photo the usual incision would be placed a bit lower. Also, some will choose a low mid-line incision if they need the 'room' or exposure for a safe outcome. Come what may, you and baby should do well.
Best of luck,
