What is Liposuction?
Liposuction is a surgical procedure that uses a suction technique to remove fat from specific areas of the body, such as the abdomen, hips, thighs, buttocks, arms or neck. Liposuction also shapes (contours) these areas. Other names for liposuction include lipoplasty and body contouring.
Liposuction isn’t typically considered an overall weight-loss method or a weight-loss alternative. If you’re overweight, you’re likely to lose more weight through diet and exercise or through bariatric procedures — such as gastric bypass surgery — than you would with liposuction.
You may be a candidate for liposuction if you have too much body fat in specific spots but otherwise have a stable body weight.
Why it’s done
Liposuction is used to remove fat from areas of the body that haven’t responded to diet and exercise, such as the:
- Chest and back
- Hips and thighs
When you gain weight, fat cells increase in size and volume. In turn, liposuction reduces the number of fat cells in a specific area. The amount of fat removed depends on the appearance of the area and the volume of fat. The resulting contour changes are generally permanent — as long as your weight remains stable.
After liposuction, the skin molds itself to the new contours of the treated areas. If you have good skin tone and elasticity, the skin is likely to appear smooth. If your skin is thin with poor elasticity, however, the skin in the treated areas may appear loose.
Liposuction doesn’t improve cellulite dimpling or other skin surface irregularities. Likewise, liposuction doesn’t remove stretch marks.
To be a candidate for liposuction, you must be in good health without conditions that could complicate surgery — such as restricted blood flow, coronary artery disease, diabetes or a weak immune system.
What you can expect
Before the procedure
Before your liposuction procedure, the surgeon may mark circles and lines on the areas of your body to be treated. Photos also may be taken so that before and after images can be compared.
How your liposuction procedure is done depends on the specific technique that’s used. Your surgeon will select the appropriate technique based on your treatment goals, the area of your body to be treated, and whether you have had other liposuction procedures in the past.
During the procedure
Some liposuction procedures may require only local or regional anesthesia — anesthesia limited to a specific area of your body. Other procedures may require general anesthesia, which induces a temporary state of unconsciousness. You may be given a sedative, typically through an IV injection, to help you remain calm and relaxed.
The surgical team will monitor your heart rate, blood pressure and blood oxygen level throughout the procedure. If you are given local anesthesia and feel pain during the procedure, tell your surgeon. The medication or motions may need adjustment.
The procedure may last up to several hours, depending on the extent of fat removal.
If you’ve had general anesthesia, you’ll wake in a recovery room. You’ll typically spend at least a few hours in the hospital or clinic so that medical personnel can monitor your recovery. If you’re in a hospital, you may stay overnight to make sure that you’re not dehydrated or in shock from fluid loss.
After the procedure
Expect some pain, swelling and bruising after the procedure. Your surgeon may prescribe medication to help control the pain and antibiotics to reduce the risk of infection.
After the procedure, the surgeon may leave your incisions open and place temporary drains to promote fluid drainage. You usually need to wear tight compression garments, which help reduce swelling, for a few weeks.
You may need to wait a few days before returning to work and a few weeks before resuming your normal activities — including exercise.
During this time, expect some contour irregularities as the remaining fat settles into position.
After liposuction, swelling typically subsides within a few weeks. By this time, the treated area should look less bulky. Within several months, expect the treated area to have a leaner appearance.
It’s natural for skin to lose some firmness with aging, but liposuction results are generally long lasting as long as you maintain your weight. If you gain weight after liposuction, your fat distribution may change. For example, you may accumulate fat around your abdomen regardless of what areas were originally treated.
