TT questions

I am new to this site. I have lost 129 lbs to date. I started at 310 and am now 181lbs.     I have not lost a great amount in the tummy area. I am going to see a plastic surgon on Feb 17th.  I am wondering how much more I will lose when I have this done. It seems I have a very large amount of thick skin very heavy looking. Will this come off or will I still be be thick looking I am just wondering because if you would ask me I think it would weigh 20 or so lbs very confussed I am sure the surgon will answer but it is so long to weight for answers. Any help would be great thanks

I just had mine removed -- but I don't know how much it weighed -- when I go back I will ask

however I have read other posts and it's ran from 2 pounds (skin does not weigh much) to 25 pounds of alot of skin and fat.
