Welcome to the forum!!!
I have never had a tummy tuck, however, the risks include bleeding, blood clots, infection, drain issues, bad reactions to anesthesia, drain issues (including infection and delayed healing), bad reactions to medication, aspiration pneumonia, and even death. I hope these risks do not scare you further. It does not mean that all or any of the aforementioned risks will affect you personally. I am merely telling you the truth. Every surgery has potential complications as well as risks.
