I have stretch marks all over my tummy. can a plastic surgery fix it? stretch marks are white.

Possibly: But remember surgery is only one option and not even a viable option for all. You haven't mentioned why you have stretch marks. But non-surgical options are laser based treatments, chemical peels, microdermabrasion, and blue light treatments. If you absolutely feel like these need to be addressed seek a formal opinion about all your options.

It Depends: There are 2 plastic surgery procedures that may or may not remove stretch marks depending on the specifics of your case. A dermolipectomy (aka panniculectomy) removes loose skin and a tummy tuck removes loose skin and tightens muscle. It is impossible to say what might or might not help online, you would need to consult with a board certified plastic surgeon to determine your best options.
