Fasting Before a Tummy Tuck (Abdominoplasty)

Fasting for this procedure

A tummy tuck is almost always performed under general anaesthetic, so you will be fully asleep and must fast beforehand. Stop eating solid food, milk and milky drinks about 6 hours before your arrival time, and you may keep sipping clear fluids (water, black tea or coffee with no milk, clear apple juice, squash with no bits) until 2 hours before. Do not chew gum, eat sweets or smoke during the fasting window. Because this is a longer operation, your team may give you a specific arrival and stop time, and sometimes a carbohydrate drink the night before or that morning, so always follow the exact instructions you are given over these general ones.

Medicines to check

Blood thinners need planning. Warfarin, apixaban, rivaroxaban, clopidogrel and similar drugs must usually be paused before a tummy tuck because of bleeding risk, but the timing is individual. See medications to stop before surgery and never stop a prescribed blood thinner without confirming with your surgeon.

Aspirin and anti-inflammatories. Aspirin, ibuprofen, naproxen and other NSAIDs can increase bruising and bleeding; your surgeon will tell you when to stop, often around a week before.

Herbal supplements and high-dose vitamins. Stop fish oil, omega-3, vitamin E, garlic tablets, ginkgo, ginseng and turmeric capsules about 1-2 weeks before, as these can thin the blood and worsen bruising over a large wound.

Diabetes medicines. Tablets and insulin usually need adjusting on the day you fast. Follow the guide to diabetes tablets before surgery and ask for a personal plan.

The contraceptive pill and HRT. Because a tummy tuck carries a real clot risk, oestrogen-containing pills or HRT may be stopped several weeks beforehand; check with your surgeon well in advance.

Take your usual heart, blood-pressure or reflux tablets with a small sip of water on the morning of surgery, unless you have been told otherwise.

When this surgery may be delayed

You have an active skin infection, an open or weeping area on the tummy, or a chest or urine infection, which raises the risk of wound problems.

Your blood thinner was not stopped in time, or a clotting blood test comes back abnormal.

Your blood sugar, blood pressure or weight is not yet in a safe range, as poor control increases wound-healing and clot risk for this large operation.

You did not fast correctly, since a full stomach under general anaesthetic risks vomit entering the lungs.

You are currently smoking or recently stopped; smoking badly impairs healing of the long abdominal scar, and surgeons often defer until you have stopped for several weeks.

Reports & documents to carry

A list of all your medicines, supplements and herbal products, with doses and the dates you stopped any blood thinners.

Any pre-operative blood test, ECG, MRSA swab or anaesthetic clinic letters.

Your loose, comfortable clothing that fits over dressings and drains, plus any compression garment or abdominal binder you were asked to buy.

Details of who will drive you home and stay with you, as you cannot travel alone or be left unsupervised the first night.

Your overnight bag, since many tummy tucks involve a planned stay of one or more nights in hospital.

What to ask your anesthesia team

What time should I stop solids and clear fluids, and should I take a carbohydrate drink beforehand?

Exactly when do I stop my blood thinner, contraceptive pill or HRT, and do I restart it after?

How is my clot (DVT) risk being managed - will I have compression stockings, calf pumps and blood-thinning injections, and for how long after I go home?

Will I have surgical drains, how do I empty and record them, and when are they removed?

How long is the recovery, when can I stand up straight, and how many weeks must I avoid heavy lifting, exercise and driving?

Frequently asked questions

Why is the blood-clot risk emphasised so much for a tummy tuck?

Abdominoplasty has one of the higher rates of venous thromboembolism (a clot in the leg or lung) among cosmetic operations. The combination of a long anaesthetic, tightening the abdomen, and reduced movement afterwards all slow blood flow in the legs. To prevent this you will usually have compression stockings, calf-squeezing pumps during surgery, blood-thinning injections, and a strong push to start walking gently within hours of the operation.

Will I have drains, and what do they involve?

Most tummy tucks include one or two thin drainage tubes placed under the skin to remove fluid and blood that would otherwise collect under the wound. They are usually left in for several days to a couple of weeks. You will be shown how to empty the bottles and write down the amounts, and they are removed once the output falls low enough. Keeping a record helps your team decide the right time.

Do I really need to stay overnight, and why is recovery so long?

Because a tummy tuck is a major operation with a long wound, muscle repair and drains, many people stay one or more nights so pain, fluids and early walking can be supervised. At home you will feel tight and bend slightly forward for a week or two, wear a compression garment, and avoid heavy lifting and strenuous exercise for around six weeks. Full healing of the scar takes months.

Can I have a tummy tuck under local anaesthetic and skip fasting?

A full tummy tuck is too extensive for local anaesthetic alone, so it is done under general anaesthetic and fasting is required. Only a very limited mini-procedure on a small area might occasionally use local anaesthetic with little or no sedation, in which case fasting rules can differ. Always confirm with your surgeon which anaesthetic you are having before assuming you can eat.
