Can someone let me know why I weigh more after liposuction/BBL? Is that normal?

After Liposuction alone and a BBL (includes liposuction + a fat transfer), the patient actually experiences increased swelling up to 14 days after surgery. This swelling is due to water retention. From 2 weeks after surgery to ~6-8 weeks, your swelling will slowly go down. It is not uncommon to gain 10-15lbs of water weight after surgery. The swelling varies depending on lifestyle (i.e. salt intake, alcohol consumption, physical activity, etc). This is also why the compression garment feels so tight for patients. 

The weight gain is from swelling. The weight gain is from swelling.That and the fact that while fat was removed it was also re-inject it into your body.  Even in the most aggressive liposuction cases, say when we remove 5 L of that the expected long-term weight loss is still only 10 pounds. Most patients  should expect to lose only a couple of pounds which is something we see as a daily fluctuations regardless. Patients often develop swelling of the whole body called third spacing after surgery. Some of this can take weeks to months to go down. Best,Mats Hagstrom,MD
