The dangers of liposuction include uneven skin, surgical complications, and risk of fat embolism. 1. After liposuction, due to the lack of subcutaneous fat, the skin is more likely to be uneven. Excessive obesity patients may also have skin irregularities after surgery due to poor skin elasticity. 2. Liposuction surgery can also lead to common surgical complications, such as nerve injury, intraoperative shock, postoperative infection, etc. 3. Fat destruction due to liposuction may result in fat embolism. The suction process may also lead to organ damage etc. Therefore, caution should be exercised before performing liposuction surgery, and there is a complete set of operating procedures before, during and after surgery. You should choose a regular hospital plastic and cosmetic surgery department in order to minimize the occurrence of postoperative sequelae.
