Are there liposuction complications that happen often?

No. Surgery is without complication. Lipo is no exception includes infection bleeding scar, assymetries need for touch up fat/pulmonary embolus but most are very unevenful procedures in the right hands.
NO. Liposuction is very safe if performed by an experienced surgeon in an appropriate setting, i.e. Surgical facility.
Safety liposuction. Liposuction is not without risk but as this is one of the most frequently performed cosmetic surgeries, it has proven to have a very high safety profile. Seek consultation with a board-certified dermatologist or plastic surgeon who is very experienced in tumescent liposuction.
Few. Liposuction is one of the safest procedures when done in the right hands. Seek a board certified plastic surgeon who adheres to the strictest qualifications.
Not common. Most of the serious risks and complications are associated with the general anesthesia and time spent under rather than the actual liposuction itself. Careful screening of the patient needs to be done before the surgery. Asymmetry or contour irregularities can occur if the surgeon is sloppy. Liposuction is an art, liposculpture being the more accurate term. Results depend on doctor's skills.
Liposuction popular. Liposuction is one of the most popular procedures and therefore the complications are widely reported in the literature but given the volume, this is relatively low. Due to the appearance of it being a simple procedure, it is performed by many inexperienced practitioners with undesireable outcomes.
No. Complications are infrequent but can be major. Use only asps member surgeon to insure training in complication prevention is in place.
Not Many. Liposuction is a very common safe and effective procedure for most patients. The most common difficulty after liposuction usually relates to incomplete reduction or small irregularities of surface. If the skin is very lax, some wrinkling can be increased volume larger volume removals (such as in lower abdomen). Complication incidence is considered low.
Not if done properly. Complications from liposuction are very rare if patient and doctor selection are made carefully. For example a patient with loose skin after weight loss is not a very good candidate for lipo whereas someone with good skin elasticity and localized extra fat is. An unskilled surgeon or a poor candidate for the procedure can cause bad results and even complications. Choose wisely!
