What Risks Come with a Skinny Person Having a Full Tummy Tuck to Correct Umbilical Hernia?

There may be several problems for you:

the hernia repair may be fixed but the umbilicus very flat is there is not much fat

the hernia can be fixed through the umbilical incision

the excess skin may not move far enough to allow a low placed incision or will require a verticle incision in the lower abdomen

you need to consider these trade-offs

Hi there-

I have never seen, read, or heard anything that would make me think thinner patients experience more of anything untoward after a tummy tuck than less thin patients do.

If you and your surgeon believe that is the procedure that will give you the best outcome, this should not be a reason you proceed in any other fashion.
