Fasting Before Adenoid Removal (Adenoidectomy)

Fasting for this procedure

Your child will have a general anaesthetic, so their stomach must be empty to stop food or milk coming up and reaching the lungs while they are asleep. Follow the 6-4-2 rule: no food, formula milk, or cow's milk for 6 hours before the arrival time; breast milk allowed up to 4 hours before; and clear fluids (water, very dilute squash, or clear apple juice with no bits) up to 2 hours before. In fact, sips of clear fluid up to the 2-hour mark are encouraged, as a thirsty, hungry child is far more settled going to sleep. Work the exact clock times back from your admission slot using our child fasting calculator, and stop chewing gum, sweets, and lollipops at the 6-hour point too.

Medicines to check

Keep giving regular medicines (such as asthma inhalers or epilepsy medication) as normal on the day, with a small sip of water — unless the hospital has told you otherwise. Epilepsy and other essential medicines should not be skipped.

Bring all inhalers to the hospital, especially blue relievers, as the breathing tube can briefly irritate a child's airway and a wheezy child may need a dose before or after.

Give any prescribed numbing cream or nasal drops exactly as instructed; don't add extra over-the-counter cold or decongestant remedies in the days before without checking with the team.

Stop aspirin-type medicines well before surgery (these are rare in children and are usually only given on specialist advice — follow your surgeon's stop plan, often around a week, as aspirin's effect on bleeding is long-lasting). For ibuprofen and other anti-inflammatory painkillers, follow your surgical team's instructions on whether and when to pause them before the operation; their effect on the blood is milder and short-lived. Note that ibuprofen is often recommended after this operation for pain, so do not assume it must be avoided afterwards. See medications to stop before surgery.

If your child takes any blood-thinning or clotting medicine, flag it early and follow the surgeon's stop plan in medications to stop before surgery.

Diabetes is uncommon at this age, but if your child is diabetic, ask the team in advance about insulin and tablet adjustments while fasting — see diabetes tablets before surgery.

When this surgery may be delayed

A cold, blocked or runny nose, cough, or sore throat in the week before — an inflamed, snotty airway raises the risk of breathing problems under anaesthetic, so surgery is often postponed a few weeks until your child is clear.

A fever or chest infection, or a wheezy, poorly-controlled asthma flare on the day.

An ongoing ear infection or discharging ear if grommets are being placed at the same time.

Recent chickenpox or measles contact, or a fresh rash that hasn't been checked.

The fasting rule was broken — if your child ate or drank milk too close to the operation, the team will usually delay or reschedule for safety.

Reports & documents to carry

Any referral letter, clinic notes, or hearing-test (audiogram) results from the ENT appointment.

A list of all medicines, inhalers, and allergies, including reactions to medicines, latex, or tapes.

Your child's red book / personal child health record and immunisation history.

Details of any previous anaesthetics or operations, and whether anyone in the family has had problems with anaesthesia.

A comfort item — favourite teddy, blanket, or dummy — plus a spare set of clothes in case of dribbles of blood.

What to ask your anesthesia team

Is the adenoidectomy being done on its own, or combined with grommets or tonsils — and how does that change the recovery and fasting time?

How will my child's pain be managed afterwards, and which painkillers (including whether ibuprofen) are safe to give at home?

What bleeding or breathing signs should make me ring the ward or bring my child back?

Roughly how long after waking can my child drink and eat, and when can we go home?

When can my child return to nursery or school and to swimming or rough play?

Frequently asked questions

Why does a cold mean my child's adenoidectomy gets cancelled?

The adenoids sit right at the top of the airway. A current cold leaves the nose and throat swollen and full of secretions, which makes the airway twitchy under anaesthetic and raises the chance of coughing, breath-holding, or a drop in oxygen. Surgeons usually wait two to four weeks after the cold clears so your child is breathing freely. It feels frustrating, but a short postponement is far safer than operating on an inflamed airway.

My child is having grommets and adenoids together — does the fasting change?

No. The fasting rule is the same whether it's adenoids alone or adenoids plus grommets or tonsils, because it depends on the general anaesthetic, not the procedure. Stick to 6-4-2: solids and formula stop 6 hours before, breast milk 4 hours, clear fluids 2 hours. The combined operation is still a day case and usually adds only a little time. Use our child fasting calculator to set the exact times from your arrival slot.

Is bleeding common after adenoid removal, and what should I watch for?

Heavy bleeding is uncommon after an adenoidectomy because the area is left to heal on its own, but the raw patch can ooze a little. Expect some blood-tinged dribble or spit, and a brief nosebleed or specks in the saliva on the first day or two. Seek urgent advice if your child swallows repeatedly, brings up fresh red blood, or vomits old dark blood. Your team will tell you which painkillers to use afterwards; ibuprofen is often recommended for pain after this operation, so follow their advice rather than avoiding it.

How quickly will my child recover after an adenoidectomy?

Recovery is usually mild and quicker than a tonsillectomy. Many children are eating, drinking, and back to themselves within a day or two. A blocked-sounding or slightly nasal voice, mild ear ache, bad breath, and a low-grade temperature are normal for up to a week as the area heals. Soft foods, plenty of fluids, and regular paracetamol help — and your team may also advise ibuprofen for pain. Most children return to nursery or school within three to seven days.
