Male breast reduction surgery (gynaecomastia)

Gynaecomastia is the enlargement of breast tissue in men that can affect one or both sides of the chest, resulting in breasts that are bigger than usual.

It is most common during puberty or with age, when hormone levels naturally fluctuate, but it can also be caused by:

• Being overweight
• Medical conditions such as an overactive thyroid, kidney disease or cirrhosis
• Medication for high blood pressure, heart conditions, stomach ulcers, psychiatric conditions, and anabolic steroids

While it isn’t harmful, gynaecomastia can cause unevenness or fullness in the chest that men may find distressing.

What is gynaecomastia surgery?

Gynaecomastia surgery, also known as male breast reduction, is a procedure designed to remove excess breast tissue, fat and sometimes loose skin to create a flatter and firmer chest.

Surgery can improve physical discomfort, reduce self-consciousness and help men feel more confident in their appearance. Depending on the amount of tissue being removed, the procedure may involve liposuction, direct excision of glandular tissue, or a combination of both, with cuts usually made discreetly around the chest to minimise visibility of scars.

Signs you may want gynaecomastia surgery

Enlarged male breasts can be more than a cosmetic concern. Some men experience discomfort, sensitivity or skin irritation in the nipples or breasts, while others may feel self-conscious about their chest shape or size. These feelings can affect daily life, including how you dress, exercise or interact socially.

By creating a more contoured chest, male breast fat reduction can help men enjoy improved comfort, greater confidence and a renewed sense of ease in both appearance and movement.

Is male breast reduction surgery right for you?

Male breast reduction surgery is a very individual decision and isn’t necessary or suitable for everyone. It’s usually considered once breast tissue has stabilised, such as after puberty or following weight changes. Certain health conditions may also affect whether surgery is safe for you.

A consultation with a specialist surgeon allows you to discuss your concerns, have your chest examined and understand what surgery can realistically achieve. Your surgeon will explain the benefits, possible risks, and recovery timeline so you can make an informed decision about whether surgery is right for you.

What are the benefits of male breast reduction surgery?

Breast reduction surgery can help improve comfort and confidence. Key benefits include:

• Improves self-confidence and body image
• Makes clothing fit more comfortably
• Reduces excess breast tissue for a flatter, firmer chest
• Reduces skin irritation or chafing
• Relieves tenderness, discomfort or heaviness in the chest area
• Supports greater ease in physical activity or exercise

Male breast reduction surgery targets the two main components of the chest — firm glandular tissue and softer fatty tissue. The approach depends on the type and amount of tissue present.

Excess fat is often removed using liposuction while surplus glandular tissue is surgically removed through small cuts, usually placed around the nipple or under the arm.

In some cases, both techniques are combined to achieve a smoother, more contoured chest. The procedure is typically performed under general anaesthetic and usually as a day case, though a short overnight stay may occasionally be needed.

Your surgeon will discuss your goals in advance and tailor the operation to your individual needs.

Before the procedure

Undergoing male breast reduction is a personal decision, and thoughtful preparation can make the experience smoother and less stressful. Your consultant and care team will guide you through every stage, ensuring you understand what to expect and that you feel comfortable moving forward.

Following your surgeon’s advice, attending all appointments, and being open about your health and lifestyle can help your procedure and recovery go smoothly.

Consultation and planning

Before your procedure, you’ll meet your care team for a consultation. This is your opportunity to discuss your goals, ask questions and make sure you understand the procedure, potential risks and post-operative care. Bring a list of any medications or supplements you take so your surgeon can advise on adjustments if needed.

Lifestyle considerations

Certain lifestyle changes may reduce your risks and speed up your recovery. Maintaining a healthy diet, exercising regularly, and avoiding smoking or excessive alcohol in the weeks before surgery can support healing. Your surgeon will give personalised guidance.

Food and drink

You will be asked to fast (avoid food and drink other than water or clear liquids) for a period before your operation as you’ll be under general anaesthetic.

Who will be involved?

From your first consultation to your final follow-up, you’ll be supported by a dedicated team led by the specialist consultant of your choice. They’ll listen to your goals, answer your questions, and guide you through every step of your treatment and recovery.

All our surgeons are highly qualified specialists who hold consultant-level positions and are registered with the General Medical Council (GMC). Many also hold memberships with leading UK cosmetic and plastic surgery associations.

Working alongside experienced nurses, anaesthetists and clinical staff in our modern, well-equipped hospitals, they’re committed to providing safe, expert care tailored to your needs.

The operation

How long does male breast reduction surgery take?

The procedure typically takes around 90 minutes, though the exact time depends on the amount of tissue being removed and the surgical method used.

Anaesthesia

Gynaecomastia surgery is performed under general anaesthetic, so you will be fully asleep and won’t be able to feel anything during the operation.

What happens straight after surgery

After your operation, you’ll be taken to a recovery room where nurses will monitor your condition. Your chest will be dressed with supportive bandages or a surgical compression vest to reduce swelling and encourage healing.

Pain during and after male breast reduction surgery

The anaesthetic means you won’t feel any pain during the procedure. Afterwards, it’s normal to experience some pain, tightness and swelling. Your care team will provide pain relief and advice to manage discomfort at home for the first couple of weeks.

Your hospital stay

Gynaecomastia surgery is usually done as a day case procedure, but some patients may be asked to stay in hospital for 1 night to ensure they are comfortable and recovering safely.

While everyone heals at their own pace, most men can gradually return to their normal daily activities in around 6 weeks.

Short-term side effects

Some swelling, bruising, tenderness, or tightness in the chest is normal after surgery. You may also notice temporary redness or small lumps in the scars, which usually fade with time.

First 24 hours recovery

Immediately after surgery, your chest will be bandaged and you’ll receive pain relief as needed. Nursing staff will monitor your condition before you are discharged.

Managing your recovery at home 

Follow your consultant’s instructions carefully once home, including wearing your compression garment, caring for your dressings, and taking any prescribed medications. Your care team will schedule follow-up appointments to check healing and monitor scars.

Wound care

Keep your chest clean and dry. Follow any dressing and wound care instructions from your surgeon, and contact your care team if you notice signs of infection, unusual swelling, or persistent redness.

Scarring

You will have permanent scars where tissue was removed, but any redness, lumps, or unevenness usually fade over time. Minor surgical revisions can be made if needed.

Pain relief 

Bandages will help control swelling, and you’ll receive pain relief while in hospital. Your consultant may provide a supply of pain medication for up to 14 days at home.

Driving

You will need someone to take you home from the hospital. Avoid driving until you can wear a seatbelt comfortably without pain and check with your insurance provider before getting back behind the wheel.

Time off work

Plan to take around a week off work, though recovery may take longer for physically demanding roles.

Resuming normal activities

Exercise and heavy lifting should be avoided for about 3 weeks. Wearing a supportive compression garment for up to 2 weeks helps the chest settle into its new shape, and most men can resume normal daily activities after around 6 weeks.

How your loved ones can help

Having support at home can make recovery easier. Friends or family can assist with everyday tasks, meal preparation, and transport to follow-up appointments, allowing you to rest and focus on healing.

Your breast reduction results and what to expect

It’s important to have realistic expectations about the results of your surgery. Your surgeon will talk you through the changes you can expect, including the new shape and contour of your chest, and any potential risks or alternatives before you go ahead.

Most men notice improvements quickly, but it can take several months — often up to 6 — for swelling to fully settle and the results to become clear. Your chest may feel different at first, but over time the appearance will become more natural as your body heals.

Although male breast reduction surgery is generally safe, as with any surgery, there are potential complications. Being aware of them helps you make an informed choice.

Possible risks include:

• Bleeding or blood collecting beneath the skin (haematoma), or fluid accumulation at the surgical site (seroma)
• Infection or delayed healing of wounds
• Scarring that may be raised, uneven or lumpy, sometimes needing revision
• Temporary or permanent changes in nipple or chest sensation, or rarely, loss of nipple tissue
• Uneven chest or asymmetry between sides, irregular contours, over- or under-correction of tissues

Signs of serious complications or infections include persistent redness, unusual swelling, discharge from the wound, severe pain or a high temperature. If you notice any of these, contact your care team immediately.

Risks associated with general anaesthesia are rare but can include allergic reactions, breathing difficulties and heart complications. Your anaesthetist will review your medical history and monitor you closely throughout the procedure to minimise any risk.

Your surgeon will discuss these risks in detail, taking into account your health, lifestyle and surgical plan, so you understand how they may affect you personally.

Surgery isn’t the only way to manage male breast enlargement. In some cases, addressing underlying medical or hormonal issues, adjusting medications that may contribute to the condition, or losing weight if excess fat is a factor can help reduce chest size.

Hormone-related treatments may be prescribed when appropriate, and psychological support can be beneficial for men who feel distressed about the appearance of their chest.
