How many cc’s of fat are you allowed to remove in one session of vaser liposuction?

The total amount allowed in the U.S. is 5L in a single treatment session. Always choose a board-certified dermatologist with extensive experience in this procedure. An expert provider will ask you to schedule your treatment in two separate sessions if the amount to be taken exceeds that limit to ensure your procedure is both safe and successful. 

in the US they limit removal to 5L at any given time. this is a recommendation.  I suggest you see an expert as the amount of removal depends on the starting size of the patient and the areas treated.  Best, Dr. Emer.

Thank you for posting your questions. My name is Dr.Javier Soto. I am a Board Certified Plastic Surgeon from Colombia
This is a great question,  In liposuction, a certain amount of fluid is injected before doing the surgery, so you need to know how much fluid was injected and how many cc's were removed to be sure about the liters that you lost, besides of it, its so difficult warranty a specific amount of fat that we can remove by one session of liposuction, the main reason,  the reaction of your body during the procedure. 
Please keep giving us feedback about your process, and I hope my answer comes to help.

Total volume that can be removed safely in an outpatient surgical facility is 5L. For those patients who need more removed, your surgery is performed at a local hospital where we are allowed to remove up to 10 L. This also depends on your starting hemaglobin. In general, we don't routinely need to remove more than 5 L even if you do your arm and abdomen. Please consider a virtual consultation with a VASER specialist.

my understanding is only Florida has a law restricting how much that can be removed in a single session. The American Society of plastic surgeons as published general safety guidelines stating that last and 5000 mL of total aspirate which typically ends up being around 4000 mL of that should be the limit in a single session as an outpatient procedure.  And ethical plastic surgeon with treat each area to completion and I ask that you come back for a second procedure if you have more than 5L of fat( actually total aspirate) to be removed.  Typically patients over 200 pounds lean towards requiring two sessions of liposuction.  Some will do 5000 mL spread over your body and call it a day.  Personally that's not how I do these procedures. We sometimes do the second procedure 48 hours later. I perform liposuction with my patients a week using local anesthesia with mild sedation in the office. Based on that it's fairly simple to bring the patient back in a couple of days to do the remaining area.  For young healthy people this seems reasonable.  Best, Mats Hagstrom MD 

Hi and welcome to our forum!
Each state has its legal maximum of supernatant fat (the amount of fat which floats to the top) which can be removed in an outpatient setting. Here in Florida, we are required to not exceed 4000 cc of supernatant fat, which amounts to about 6-8 pounds. Larger amounts can be removed if multiple procedures are staged at intervals. 
The procedure is designed for reshaping, not weight loss. There are much more satisfactory ways to achieve significant weight loss, such as the gastric sleeve, a bariatric surgical procedure. With a sleeve, you can reduce your weight by 60-150 lbs with one procedure and an overnight stay.
Best wishes...
