Since you have lost 100 lbs, I assume you have a lot of extra loose skin. This makes these procedures much more difficult and time consuming to perform nicely.
Each one of the operations you listed takes several hours to perform. This is true even if there are two surgeons working at the same time.
It is not a good idea to do all 3 in your case. The anesthesia time will be too long. This increases your risk for all kinds of problems, especially the formation of blood clots in your legs.
Also, this involves a lot of skin and fat removal, which equals blood loss. Doing all 3 can put you at risk for losing too much blood and possibly needing a transfusion.
Lastly, if you do all 3, the surgeons will not be able to give their full attention to any one of the procedures. They will become exhausted (after all, each procedure is very labor intensive). Although we always try to do our very best for any procedure we do, this is just too much to do in one setting. It may compromise the result that surgeon can achieve.
