Abdominal Liposuction improves body shape by removing fat deposits which are resistant to exercise. The procedure is usually performed on an out-patient basis and can use an ultrasonic technique which liquifies the fat before it is suctioned away. Patients may experience temporary bruising, swelling, numbness or burning, or drainage from incision sites. Potential complications include bleeding, infection, asymmetry, skin rippling or discoloration, fluid retention, or excessive fluid loss which may lead to shock (only with large volume liposuction). Patients generally return to work and to strenuous activity within two weeks. Swelling and bruising generally subside within one to three months and that may be reduced through use of tumescent or ultrasonic techniques.
