Is there anyone who has had a revision surgery after the sleeve because they hadn't lost what they should have?

I didn't get the sleeve done but I know someone who has. She goes to the gym religiously 6 days a week and eats fairly well yet after a year and a half has only lost about 85 lbs. The sleeve has worked but considering our doctors statement about how the sleeve will result in the most significant loss of all three procedures yet it hasn't yet yielded such results I wanted to know if anyone had had a surgery after, and if so, what it was.

Thanks

Also, I guess it would help to say she started out at 330+
