The dangers of liposuction include infection, accidental puncture of an internal organ, development of a fat embolism, kidney problems and heart problems, Mayo Clinic says. A fat embolism is a condition where a piece of fat breaks loose, enters the bloodstream and becomes trapped in the blood vessels that lead to the lungs or brain. Temporary or permanent numbness in the affected areas is also possible.
Liposuction can leave a patient with loose skin or other contour irregularities, Mayo Clinic says. When skin is thin or has poor elasticity, it can look wavy, bumpy or withered after liposuction. This can also occur because of uneven fat removal. The tools a surgeon uses for liposuction can damage overlying skin and leave it with permanent spotting. Fluid can accumulate under the skin at affected sites. This may be temporary, but sometimes a doctor must drain the fluid with a needle. The chances of complications increase when a surgeon performs liposuction on a larger area or when he operates on several areas at once.
Liposuction is a type of surgery where a doctor uses suction to remove fat from areas of the body, explains Mayo Clinic. A surgeon can remove small amounts of fat in his office, but larger operations require a hospital setting.
