Complications specific to liposuction are infrequent and usually minor. However, as with any surgery, there are risks, including the possibility of:
- Bleeding under the skin (hematoma) after surgery.
- Scars. In most cases scarring is minimal, though lumpy red scars can form in some people.
- Infection, though unusual after this type of surgery, may occur and require antibiotic treatment.
- Irregularities in skin contour and depressions in the skin may occur.
- With wet liposuction pulmonary edema (fluid build up in the lungs) can occur as a result of the fluid that is injected and needs immediate treatment. The fluid used can also cause allergic reactions in some patients.
- Reaction to the anesthesia.
It is impossible to guarantee symmetrical body appearance and smooth skin after liposuction surgery. Some numbness can occur and there may be significant bruising and swelling which may take several months to settle completely.
Risks can be reduced by following the surgeon's instructions before and after surgery. The FAQ question "What are the risks of plastic and cosmetic surgery?"
has additional details on risks and how to minimize them.
