Liposuction is a type of cosmetic surgery used to remove unwanted body fat. The operation is also known as liposculpture or suction-assisted lipectomy.

Liposuction is carried out on areas of the body where deposits of fat tend to collect, such as the buttocks, hips, thighs and tummy. The procedure is generally used to improve appearance rather than treat health conditions.

Liposuction permanently removes fat cells and can alter body shape, although the results may not last if you put on weight after the procedure.

Liposuction isn't a treatment for obesity, and it won't remove cellulite or stretch marks.

Conditions that can be treated with liposuction include lymphoedema (where fluid accumulates in body tissue) and gynaecomastia (where fatty swellings develop under a man's nipples).

Things to consider

Having any kind of cosmetic surgery, including liposuction, is a major decision. It can be expensive and time consuming, and the results can't be guaranteed.

It's important to ask yourself why you want to have cosmetic surgery. It's a good idea to discuss your plans and other possible options with your GP before going ahead with treatment.

Liposuction is usually only recommended if you've tried changing your lifestyle but this hasn't helped.

If you decide to have liposuction, be absolutely sure about your reasons for wanting to have it.

Choosing a surgeon

If you decide to have liposuction, it's important that the surgeon and other healthcare professionals carrying out the procedure are fully qualified and experienced.

You should discuss the procedure in detail with your surgeon. Ask as many questions as you need to so you're fully aware of what the procedure involves, how it will be carried out, what the results will be, and whether there will be any after effects.

How liposuction is performed

Before having a liposuction operation, your surgeon should discuss the procedure with you to decide which technique they'll use to prepare the area where fat is to be removed.

Possible preparation techniques include injecting the area with a solution containing anaesthetic and medication, and breaking up the fat cells using high-frequency vibrations.

Once the area is prepared, a small cut is made. A suction tube attached to a specialised vacuum machine is then inserted. Several cuts may be made if there's a large area being treated.

Liposuction is usually carried out under general anaesthetic, although local anaesthetic or epidural anaesthetic may be used in some cases.

Risks and recovery

After the operation, the treated area will be bandaged and stitched, and you may need to wear elastic compression clothing to reduce swelling. You may need to stay overnight in hospital if general anaesthetic is used.

It usually takes about two weeks to make a full recovery, but it can take up to six months to see noticeable results, as the treated area may take time to settle down.

Like all types of surgery, liposuction carries a number of risks. These include bruising, infection, scarring, irregularities and numbness.

Liposuction on the NHS

As liposuction is usually used to improve your appearance rather than your health, it's not normally available on the NHS. It may be available if it's used as part of reconstructive surgery or to treat certain conditions, such as lymphoedema.

To receive cosmetic surgery on the NHS, you'll normally need a referral from your GP. You'll have to have a consultation with a plastic surgeon and an assessment by a psychiatrist or psychologist. They'll decide whether there's enough social, psychological or physical benefit to justify surgery.
