Tummy Tuck and Hernia Repair
I'm afraid it is impossible to answer your question with the information you have provided. First, I do not know how tall you are. If you 6 foot 3 inches or anything less, then you first need to lose weight before considering either hernia repair or a tummy Tuck, unless you're having significant risks from the hernia itself. A general surgeon should be able to assess these risks. I suspect you are probably less than 6 foot 3 inches. This could be one of the reasons that you have recurrent hernias. Losing to a normal weight can significantly improve your chances of having a successful hernia repair. Secondly, you gave us no inflammation on your health otherwise.
Multiple prior surgeries
Short answer: probably not. Recurrent hernia is a tough problem, let them concentrate on that and get that fixed first. Of course, it is impossible to know your entire story in your 3 lines; it may be that if you lay out your history to a board certified plastic surgeon, it may be reasonable to attempt. Good luck.
