6 days should be fine to return to light work. I would have to assume the fat transfer is to your buttocks, which is the most common area for fat transfer. If that is the case you will likely have to keep pressure off of the area by sitting on a special pillow or a pillow placed under the thighs.
Dolores,When to return to work depends on a number of things:How much liposuction you will getThe areas of liposuctionWhat kind of work you doYour individual recovery time and pain thresholdMany of my patients are able to return to work one week after minimal to moderate liposuction.I hope this was helpful,Dr Daniel BarrettBeverly Hills, CA
