How to Prepare for Gynecomastia Surgery: A Checklist

Preparing for gynecomastia surgery involves completing your medical assessment, agreeing on a medicine plan, stopping smoking and following personalised fasting instructions. Arrange transport, support at home, and time away from strenuous activity. Your surgeon and anaesthesiologist should provide written instructions suited to your health, procedure and type of anaesthesia.

Start With a Clear Surgical Plan

Before confirming the operation, make sure you understand what the surgeon intends to treat.

Ask whether your chest needs fat removal, gland excision, skin removal, or a combination. Discuss incision locations, possible nipple sensation changes, and realistic expectations for the contour.

You should also know:

• Where the operation will take place.
• Who will perform it.
• What anaesthesia is planned.
• Whether discharge is expected the same day.
• Who to contact if a problem develops.
• What the written quote includes.

A consultation is an opportunity to resolve uncertainty before surgery. See the gynecomastia consultation guide for what the assessment involves.

Your Gynecomastia Surgery Preparation Checklist

These are planning stages, not a universal timetable for stopping medicines or fasting.

Complete the Medical Assessment and Requested Tests

Tell the team about existing health conditions, allergies, previous operations and any problems with anaesthesia.

Mention diabetes, high blood pressure, bleeding problems, sleep apnoea and heart or lung disease. Bring relevant reports and explain any recent changes in your health.

ASPS advises that preparation may include laboratory testing or a medical evaluation. The required investigations depend on your circumstances. 

Some tests investigate the cause of enlargement, while others assess fitness for surgery. Read Tests before gynecomastia surgery before ordering a test package yourself.

Complete any recommended follow-up on abnormal results. Having a report is different from having it reviewed and acted upon.

Get a Written Medicine and Supplement Plan

Give the surgeon and anaesthesiologist a complete list of everything you take, including doses and frequency.

Include prescribed medicines, painkillers, herbal remedies, vitamins, gym supplements, testosterone products and anabolic steroids.

Some products can affect bleeding, blood pressure, blood sugar or anaesthesia. ASPS specifically highlights aspirin, anti-inflammatory medicines and herbal supplements during preparation.

However, do not stop prescribed aspirin, blood thinners or other regular medicines yourself. The decision may require coordination with the prescribing doctor.

Ask for clear instructions covering:

• The last dose before surgery, if a medicine must be withheld.
• What to take on the morning of surgery.
• When to restart anything that was paused.
• What to do if you accidentally miss or take a dose.

Avoid introducing new supplements shortly before the operation without discussing them.

What if you use diabetes or weight-loss medicines?

Tell the team early, including if you use semaglutide, tirzepatide, or another GLP-1-based medicine.

These medicines can affect stomach emptying. ASA patient guidance explains that many patients can continue treatment, while individual risk factors may require changes to preparation or timing. Do not apply a blanket “stop for one week” rule yourself. 

Insulin and other diabetes medicines also need a specific plan around fasting.

Stop Smoking Early and Discuss Other Nicotine Use

Smoking increases the risk of wound-healing problems, infection and anaesthetic complications.

WHO reports that stopping approximately four weeks or more before surgery reduces postoperative complications. Your surgeon may recommend a longer period depending on the operation and your health. 

Tell the team about cigarettes, vaping, chewing tobacco and nicotine products. Ask for help with cessation and advice on suitable treatments rather than assuming that switching products meets the surgical requirements.

Be honest if you have recently smoked. The team needs accurate information to make a safe plan.

Maintain Your Usual Nutrition and Avoid Crash Dieting

Preparation is not the time for a sudden extreme diet or a last-minute attempt to transform your chest.

Eat regular, balanced meals and discuss any major ongoing weight loss with the surgeon. If you have had bariatric surgery, nutritional deficiencies, or poor appetite, mention this during assessment.

Avoid starting “detox” plans, hormone boosters or bodybuilding cycles. Tell the doctor about heavy alcohol use so they can advise you appropriately, including whether stopping requires medical support.

Confirm Your Fasting Instructions

Fasting instructions depend on the planned anaesthesia, your health and the facility’s protocol.

Ask for the exact times to stop:

• Solid food.
• Milk and other non-clear drinks.
• Clear fluids.
• Chewing gum or sweets, if restricted by your team.

Do not assume that “local anaesthesia” means you can eat normally. Sedation or a change in the anaesthetic plan may affect the instructions.

Avoid fasting longer than instructed, and clarify anything unclear before the day of surgery.

If you eat or drink outside the agreed instructions, tell the team exactly what you had and when. They will decide whether the procedure can proceed.

Arrange Transport and Support at Home

For outpatient surgery, ASPS recommends arranging someone to drive you to and from the facility and stay with you for at least the first night. 

Confirm the discharge requirements with the clinic, especially after general anaesthesia or sedation. Do not plan to drive yourself home.

Your support person should know:

• When and where to collect you.
• How to obtain prescribed medicines.
• Where the discharge instructions are kept.
• Which symptoms require a call.
• How to contact the surgical team.

If you live alone, discuss this before surgery rather than waiting until discharge.

Prepare Your Home and Work Schedule

Set up a comfortable resting area with essentials within easy reach. Have suitable clothing, simple meals, and any prescribed supplies ready.

Ask whether the clinic supplies the compression garment or expects you to obtain one. Confirm the size and fit rather than buying a very tight garment yourself.

Arrange help with tasks that involve lifting, pushing, or reaching. Discuss your actual job duties with the surgeon: returning to desk work and returning to heavy manual work are different decisions.

During planning with Dr. Ashutosh Shah at Elegance Clinic, explain your work, exercise, and travel commitments so the recovery instructions fit your circumstances.

What Should You Do the Day Before Surgery?

Follow the clinic’s washing instructions and pack the items you have been asked to bring.

Do not shave or wax the chest yourself unless the surgical team specifically instructs you. NHS preparation guidance advises against shaving near the surgical site and applying body lotions on the day of surgery. 

Useful items to prepare include:

• Identification and admission documents.
• Requested reports and previous medical records.
• A current medicine list.
• Loose, comfortable clothing.
• Your support person’s contact details.
• Any equipment the team has requested, such as your prescribed CPAP machine.

Confirm the arrival time, which may be earlier than the operation time.

Tell the Clinic if You Become Unwell

Report a new cough, cold or fever before attending. NHS guidance advises contacting the surgical team, who will assess whether the operation can proceed. 

Also mention a new rash, sore or cut near the chest, a change in medication or another significant health problem.

Do not hide symptoms because leave or travel has already been arranged. An early call gives the team more opportunity to assess the situation.

Key Takeaways

• Complete your assessment and have requested reports reviewed.
• Obtain personalised medicine and fasting instructions.
• Stop smoking early and disclose all supplements and substances.
• Arrange transport, overnight support and practical help.
