Liposuction weight gain or fluid retention?

You are correct that swelling is common and expected after surgery which often equates to a higher number on the scale. Closely following your surgeon's instructions regarding compression, massage, and activity will help manage this. Typically around 6 weeks post op the majority of the swelling will be resolved.

Weight gain is observed when you stop wearing your garments 24 hours a day; this usually happens at 1 week once you start getting complacent and will be most dramatic over the first month. From one month to three months you will gradually reduce your swelling and weight. I recommend that patients wait three to six months before investing into buying outfits etc.

Weight gain from fluid used and swelling is seen right away with liposuction and can last up to 6 months. The majority of excess fluid occurs in the first month.
