In the state of Florida, only 4 liters can be removed at an outpatient facility. Only 1 liter can be removed when combined with another procedure such as an abdominoplasty, etc.. If you are operated on in a Hospital greater amounts can be removed but the risk goes up as well. It is usually not wise to remove over 6-8 liters of fat. Talk to a Board Certified Plastic Surgeon and ask him/her all of your questions.
Removal of large amounts of fat during liposuction remains a debatable topic relative to safety. Most plastic surgeons limit the amount to four or 5 L but this is not yet a standard of care. Patients have to be dealt with on an individual basis.
