Plastic Surgery

How breast and body operations differ, what causes the changes they target, what each option cannot do, what needs examination and which signs are urgent.

This section covers cosmetic surgery of the breast and body: breast enlargement, lift and reduction, male breast reduction, liposuction, tummy tuck and skin removal after weight loss. Changes in breast and body shape have many causes, from pregnancy and weight change to hormones and medicines, and some of these need a medical answer before any cosmetic one.

In short

Each body operation addresses one part of the problem: liposuction removes fat but is not a treatment for obesity1, a tummy tuck removes skin and repairs muscle4, and a breast lift raises the breast without significantly changing its size.5 Breast implants do not last a lifetime.2 Body surgery carries a risk of blood clots, which travel adds to.3 Stable weight, good general health and an in-person assessment come before any choice.

What this field covers

  • Breast enlargement: silicone or saline implants placed in front of or behind the chest muscle2, or fat transfer.
  • Breast lift (mastopexy): removes excess skin and tightens surrounding tissue to raise the breast.5
  • Breast reduction, and male breast reduction for gynaecomastia (enlarged breast tissue in men).6
  • Liposuction: removes fat from areas that have not responded to diet and exercise.1
  • Tummy tuck (abdominoplasty) and other skin-removal operations such as arm lifts after major weight loss.

Start with the cause

Concern or symptomPossible causesUsual first step / type of specialist
Sagging breastsPregnancy, breastfeeding, weight fluctuation, ageing, gravity, inherited skin qualities5Plastic surgeon; deciding whether the issue is skin and position, volume, or both5
Breasts feel too small or unevenNatural development; volume change after pregnancy or weight lossTime to be sure why you want implants2; plastic surgeon assessment
Enlarged breasts in a manHormone changes at puberty or after 50; being overweight; certain medicines; anabolic steroids; thyroid, kidney or liver disease6GP first, to look for an underlying cause; it often needs no treatment6
A breast lump, skin change, or nipple discharge or bleedingNeeds medical assessment; not a cosmetic concern6GP
Stubborn fat in one areaFat that resists diet and exercise1; general weight gain; medical conditions affecting fat distributionLifestyle and weight review first; liposuction suits people who are not overweight and have firm, elastic skin1
Loose or protruding abdomenAgeing, heredity, pregnancy, previous surgery, large weight changes; separated abdominal muscles4Plastic surgeon; postpone if more weight loss or a pregnancy is planned4
Fat, loose skin and weak muscle need different treatments; many people have more than one.

Main types of option

OptionWhat it can doWhat it cannot do
No treatment, or treating the underlying causeAvoids surgical risk; gynaecomastia may improve with weight loss, hormone-altering medicines or treatment of another condition6Remove loose skin or change breast shape
LiposuctionRemove localised fat1Treat obesity, cellulite or stretch marks1; tighten loose skin
Tummy tuck and skin removalRemove excess skin and fat and usually repair separated muscles4Replace weight loss or exercise; results lessen with major weight change4
Breast implantsAdd volume2Last a lifetime; some people need further surgery after about 10 years2
Breast lift or reductionRaise the breast and remove excess skin; reduce size5Add fullness to the upper breast without implants5
Every operation also carries bleeding, infection, blood clot and anaesthetic risks, and some people need a second operation.12

What cannot be decided online

Skin elasticity, the split between fat and loose skin, muscle separation, breast tissue and chest wall shape all need examination. Implant type and placement are decided with the surgeon after weighing silicone against saline.2 Any breast lump or nipple change is checked medically before cosmetic surgery is discussed.6

Your clot risk also needs a personal review. Surgery, journeys longer than 4 hours, smoking, being overweight, hormone treatments including oestrogen-containing contraception, and a previous clot all raise the risk of deep vein thrombosis (DVT).3 Weight stability and plans for pregnancy change timing.4

When to seek urgent medical help

  • Throbbing pain and swelling in one leg (or arm), with red or darkened skin or swollen veins: get an urgent GP appointment or call NHS 111.3
  • Those symptoms with breathlessness or chest pain: call 999 or go to A&E, as this can be a clot in the lung. Do not drive yourself.3
  • After breast surgery: unexpected pain, unusual swelling or skin colour changes need contact with the team that operated as soon as possible.2
  • After liposuction: severe pain or any unexpected symptom needs prompt contact with the team that operated.1
