Liposuction, sometimes referred to as "lipo" by patients, slims and reshapes specific areas of the body by removing excess fat deposits and improving your body contours and proportion.Liposuction, or simply lipo, is a type of cosmetic surgery that removes fat from the human body in an attempt to change its shape. Evidence does not support an effect on weight beyond a couple of months and it does not appear to affect obesity related problems. In the United States it is the most commonly done cosmetic surgery.Serious complications include deep vein thrombosis, organ perforation, bleeding, and infection. Death occurs in about one per ten thousand cases. The procedure may be performed under general, regional, or local anesthesia. It then involves using a cannula and negative pressure to suck out fat. It is believed to work best on people with a normal weight and good skin elasticity. While the suctioned fat cells are permanently gone, after a few months overall body fat generally returns to the same level as before treatment. This is despite maintaining the previous diet and exercise regimen. While the fat returned somewhat to the treated area, most of the increased fat occurred in the abdominal area. Visceral fat - the fat surrounding the internal organs - increased, and this condition has been linked to life-shortening diseases such as diabetes, stroke, and heart attack.
- One treatment may be all you need to reshape problem areas
- Treat more areas—and larger areas—in one procedure
- May be performed with either local or general anesthesia
- More consistent and predictable result than noninvasive treatments
A tummy tuck (abdominoplasty) is a major surgical procedure requiring general anesthesia, and involves liposuction and excision to remove fat, plus a large excision of skin. The typical result is usually a flatter tummy with a large scar extending from the pubic area to the lower abdomen to anterior hips. Because the surgeon can directly visualize the muscles of the anterior abdominal wall during a tummy tuck, lax abdominal muscles can be surgically tightened during a tummy tuck procedure. Before the invention of liposuction, a tummy tuck was the only surgical method for removing excessive abdominal fat.

Techniques for Liposuction aspirate
Liposuction aspirate In general, fat is removed via a cannula (a hollow tube) and aspirator (a suction device). Liposuction techniques can be categorized by the amount of fluid injection and by the mechanism in which the cannula works. Ultrasound-assisted liposuction techniques used in the 1980s and 1990s were associated with cases of tissue damage, usually from excessive exposure to ultrasound energy.Third-generation UAL devices address this problem by using pulsed energy delivery and a specialized probe that allows physicians to safely remove excess fat People who undergo liposuction usually have a stable body weight but would like to remove undesirable deposits of body fat in specific parts of the body. Liposuction is not an overall weight-loss method. It is not a treatment for obesity. The procedure does not remove cellulite, dimples, or stretch marks. The aim is esthetic. It suits those who wish to change and enhance the contour of their body. Liposuction permanently removes fat cells, altering the shape of the body. However, if the patient does not lead a healthy lifestyle after the operation, there is a risk that the remaining fat cells will grow bigger. The amount of fat that can be safely removed is limited. There are some risks, including infection, numbness, and scarring. If too much fat is removed, there may be lumpiness or dents in the skin. The surgical risks appear to be linked to the amount of fat removed.
Liposuction is normally done for cosmetic purposes, but it is sometimes used to treat certain conditions.
• Lymphedema: A chronic, or long-term, condition in which excess fluid known as lymph collects in tissues, causing edema, or swelling. The edema commonly occurs in the arms or legs. Liposuction is sometimes used to reduce swelling, discomfort, and pain.
• Gynecomastia: Sometimes fat accumulates under a man's breasts.
• Lipodystrophy syndrome: Fat accumulates in one part of the body and is lost in another. Liposuction can improve the patient's appearance by providing a more natural looking body fat distribution.
• Extreme weight loss after obesity: A person with morbid obesity who loses at least 40 percent of their BMI may need treatment to remove excess skin and other abnormalities.
• Lipomas: These are benign, fatty tumors.
The operation-:Before the operation, patients will need to undergo some health tests to ensure they are fit for surgery. The following recommendations may be made. People who use regular aspirin and anti-inflammatory drugs should stop taking them at least 2 weeks before surgery. Women may be asked to stop taking the contraceptive pill. Patients with anemia may be asked to take iron supplements. The individual will need to sign a consent form. This confirms that they are fully aware of the risks, benefits, and possible alternatives to the procedure
During the operation
The procedure takes around 1-4 hours.
Patients may receive a general anesthetic before the procedure, which can last for 1 to 4 hours.
An epidural may be used for treatments on the lower body. In this case, the anesthetic is injected into the epidural space surrounding the dura, or fluid-filled sac, around the spine. This partially numbs the abdomen and legs.
A local anesthetic might be used when liposuction is done on very small areas.
If the patient requires only local anesthesia, they might be asked to stand up during the procedure to ensure proper fat removal.
There are a number of liposuction techniques.
Tumescent liposuction: Several liters of a saline solution with a local anesthetic (lidocaine) and a vessel-constrictor (epinephrine) are pumped below the skin in the area that is to be suctioned. The fat is suctioned, or sucked out, through small suction tubes. This is the most popular form of liposuction.
Dry liposuction: No fluid is injected before the fat is removed. This method is seldom used today. There is a higher risk of bruising and bleeding.
Ultrasound-assisted liposuction (UAL): Also known as ultrasonic liposuction, the cannula is energized with ultrasound. This makes the fat melt away on contact. The ultrasound vibrations burst the walls of the fat cells. This emulsifies, or liquified, the fat, making it easier to suction out. This method is suitable for fibrous areas, such as the male breast, back, and in areas where liposuction has been done before. After ultrasonic liposuction, suction-assisted liposuction is done to remove the liquefied fat.
Power-assisted liposuction (PAS): Also known as powered liposuction, PAS uses a specialized cannula with a mechanized system that rapidly moves back-and-forth, allowing the surgeon to pull out fat more easily.
Laser Assisted Lipolysis (LAL): Also known as laser-guided lipo, this procedure requires the use of tumescent fluid. It is a less invasive and bloody procedure than the traditional liposuction method for removing fat.A small tube is inserted through a small incision to deliver laser energy and heat into the fat that is under the skin. After the operation, the surgeon may leave the incisions open so that excess fluid and blood can drain from the body.
After the Liposuction Operation
After the operation, the patient might experience numbness in some areas.
• Anesthetic: Those who have a general anesthetic usually spend the night in hospital. Those who had a local anesthetic may be able to leave hospital on the same day.
• Support bandages: Either an elasticated support corset or bandages will be fitted for the targeted area.
• Antibiotics: These may be given immediately after the operation.
• Painkillers: Analgesics can help relieve pain and inflammation.
• Stitches: The surgeon will remove the stitches in a follow-up appointment.
• Bruising: Significant bruising may occur in the targeted area.
• Numbness: There may be numbness in the area where fat was removed. This should improve in 6 to 8 weeks.
The results of liposuction will not be clear until the inflammation goes down. In some cases, this may take several months. Most of the swelling settles after about 4 weeks, and the area where fat was removed should appear less bulky. People who maintain their weight can usually expect permanent results. Those who gain weight after the procedure may find that their fat distribution alters. Those who previously had fat accumulating in their hips might find that their buttocks become the new problem area.
