Liposuction is a relatively safe procedure, however with any medical procedure there are still risks that must be taken into consideration. Although rare, infection is possible. This risk is reduced by the antibacterial action of the tumescent fluid and prophylactic antibiotics which are given prior to and after the procedure.
Seroma, is also possible although extremely rare. Seroma is fluid that remains in the skin tissue that becomes infected and in rare cases this fluid may require to be drained from the area. Commonly it can be treated by stronger antibiotics.
Any surgical or invasive procedure carries risks. Before proceeding, you should seek a second opinion from an appropriately qualified health practitioner.
