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

It is recommended that you contact your plastic surgeon and get his operative notes at the very least.

Probably you will want to have the plastic surgeon interface with the ObGyn to make sure they are both clear on exactly what procedure was done for you when you had your tummy tuck.

Chances are you will not have a problem, but if something special was done, i.e. mesh repair for example, this might make it difficult for the ObGyn, and you might want to have the plastic surgeon (or a plastic surgeon) scrub in on the operation.

There's no problem with having a C section after your tummy tuck.  The same incision should be used and exposure will be easy because they can actually extend their skin incision a little bit more than usual since you already have a scar.  They'll not be doing a tummy tuck though, just your cesarean and your skin may not retract as well as it did years ago.  This may be something to consider...

Generally speaking, your gynecologist should be able to proceed with very little change in technique from a typical c-section other than a slightly higher Pfannenstiel incision in the abdominoplasty scar./

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,
