How soon can you have a tummy tuck after breast reduction?

As long as you have healed and all the swelling has settled you can consult regarding the additional procedure. Not sure why you didn't choose to have the procedures at the same time. I personally tend to leave 6 months between procedures (mainly due to waiting list) but can be performed sooner.

You should wait at least 6 weeks. Consult with an experienced board certified plastic surgeon. Best of luck. Regards,. 

I see no reason why you could not have a tummy tuck after breast reduction surgery. I often do both surgeries at the same time. As long as your recovery has been uneventful and you have some help at home it should be okay. Recovery after tummy tuck is much harder than breast reduction.
