The risks of liposuction, as with any surgery, include a (low) risk of post-operative infection, bleeding, and swelling.
Some risks and side effects of this surgery include skin discoloration, rippling skin, persistent swelling, unsatisfactory wound healing, asymmetry or irregular contours, and thermal burn from ultrasound when this technique is used.
Other possible risks include local anaesthesia related complications, nerve damage, damage to muscles, lungs, blood vessels, and abdominal organs, as well as deep vein thrombosis and cardiac and pulmonary complications.
Your surgeon will discuss all the risks with you before the procedure.
