Surgery in Ramadan: Tell the Team First, Then Ask Your Scholar
If an operation falls in Ramadan, tell the surgical and anaesthesia team you are fasting before anything else. Whether a particular anaesthetic breaks the roza is a question for a qualified scholar. The fasting plan for the day belongs to the team, and it should be written down.
The short version
- Tell: the surgical team, the anaesthetist and the pre-assessment nurse, at the first contact and again on the day.
- Get it in writing: the last time for solid food, milk and clear fluids.
- The ruling: whether a given anaesthetic or procedure breaks the fast goes to a qualified scholar, not to this page.
- Never: skip a hospital fasting instruction quietly. It exists for safety.

Why does a planned operation need its own fasting plan?
Food in the stomach is the main worry before a general anaesthetic. The cut-off times exist so that the stomach is empty when the anaesthetic starts. That is the whole reason the clock matters. So pin the clock down.
The NLG adult fasting guidance says no solid food for six hours before a general anaesthetic. Clear fluids, such as water, squash without bits, or tea and coffee without milk, are allowed up to two hours before. Milk has its own cut-off, so ask the team for that time. On the day itself, do not use chewing gum, suck on sweets or smoke. Six hours for solid food, two for clear drinks, and a written time for milk.
Hospital clock times can differ from one trust to the next. A leaflet from another hospital may not match yours, and that is fine, because yours is the one that counts. Your own list’s written instructions win over any general guide, including this one.
What should you ask the team before the day?
- Say you are fasting. Ramadan 2027 is expected around 8 February, with the exact start depending on moon sighting, so give the team the month rather than a fixed date.
- Ask about the date. For an elective operation, ask whether the date can move outside the month. Clinic lists fill up, so ask early.
- Get the cut-off times in writing. You need the last time for solid food and milk, and the last time for clear fluids.
- Ask which medicines to take on the day. The pre-assessment team decides which regular medicines continue. Do not change one on your own.
- Ask what happens if sugar drops. If you have diabetes, ask how a low would be treated while you are nil by mouth.
- Put the answers on a card. Keep it in your pocket. Show it at the ward door.
The insider step: ask for it on the chart
Ask the anaesthetist to write your fasting instructions onto your chart, so the plan is set by the team and not guessed at on the day. Check the chart the day before. Ask the ward nurse to read the times back to you.
Can an elective operation move out of the month?
Sometimes. A date can often be discussed if you ask early and give the reason. The clinic list and the medical need decide the timing, not the calendar. Ask the surgical team rather than the reception desk, because they know how much a delay would matter medically.
If the date cannot move, the procedure goes ahead on the medical timetable. The fasting plan is then built around it.
Does the type of anaesthetic change the plan?
It can. General anaesthesia, spinal or epidural, and local anaesthetic with sedation can each come with different cut-off rules. Name the exact procedure and the anaesthetic type in your question. That way the team can answer for your case, not for a case in general.
The distinction people often ask about, between local and general anaesthesia, is a religious question. Take it to a local scholar with the procedure written down. On the medical side, the team’s instructions stand.
| Question to ask | Why it matters |
|---|---|
| Last time for solid food and milk? | Empties the stomach before the anaesthetic |
| Last time for clear fluids? | Usually up to two hours before |
| Which regular medicines on the day? | The pre-assessment team decides |
| What if sugar drops beforehand? | Sets the plan while you are nil by mouth |
What if your sugar drops before the operation?
A low sugar is treated quickly. The usual NHS approach is fast-acting sugar, such as glucose tablets, a small glass of fruit juice or a sugary fizzy drink, followed by a recheck after 10 to 15 minutes. Simple, fast, and well understood.
While you are nil by mouth, though, the team decides what goes in. If a low starts before the operation, tell them at once. Do not wait for the next routine check.
Does urgent surgery follow the fasting calendar?
No. Urgent surgery goes ahead on the medical timetable, not the fasting calendar. If you are admitted in an emergency, tell staff you are fasting so they can plan food, drink and medicines around it, then follow their lead.
Do not refuse or delay treatment because of the fast. Once you are safe, the religious side can be taken to your scholar.
Tell the team about every blood thinner and regular medicine you take, including warfarin or clopidogrel, so they can plan any changes before the operation. Only the team makes those decisions. Do not stop a regular medicine yourself to make the fast easier.
If your sugar falls under 70 mg/dL, or rises over 300 mg/dL, tell the team straight away. Chest pain, fainting or confusion needs urgent help now.
What is the short answer for a planned operation in Ramadan?
Tell the team you are fasting. Get the cut-off times in writing. Treat the hospital’s plan as the safety rule for the day, and take the question of whether a particular anaesthetic breaks the fast to a qualified scholar. A written time beats a remembered one, every time.
For the warning signs during the fast itself, see the fasting warning signs guide. If you need an injection or a blood test during the month, read injections and blood tests while fasting. More Ramzan health guides sit in the Ramzan Health hub.
Questions about surgery and fasting in Ramadan
Does anaesthesia break your fast?
Whether a particular anaesthetic breaks the fast is a ruling for a qualified scholar, and this page gives none. Take the exact procedure and the anaesthetic type to your scholar, and keep the medical cut-off times separate from the religious question.
Can you have surgery while fasting in Ramadan?
Yes, an operation can happen during Ramadan, but the team sets the fasting cut-offs for the list. Tell them you are fasting before the day, so the plan is made around your fast and not on the morning of the operation.
What is the fasting rule before a general anaesthetic?
NLG guidance says no solid food for six hours before a general anaesthetic, and clear fluids up to two hours before. Milk has its own cut-off, so use the times written for your list.
Does sehri count as food before surgery?
Yes, a sehri meal counts as solid food, so it falls under the cut-off the team gives you. Ask whether any sehri is allowed on the operation morning, and follow the written time.
Can an elective operation be moved to avoid Ramadan?
Sometimes. Ask the surgical team early, because a change depends on the clinic list and the medical need. If the date cannot move, the operation goes ahead on the medical timetable.
Do people with diabetes get different fasting instructions?
They should get individual instructions. Tell the pre-assessment team you have diabetes, and ask how a low sugar would be treated while you are nil by mouth.
Should blood thinners be stopped before surgery in Ramadan?
Do not stop or change one yourself. Tell the team every blood thinner you take, and let them decide, after reading your full medicine list, whether anything changes before the operation.
What should you ask the anaesthetist before Ramadan surgery?
Ask for the last times for solid food, milk and clear fluids, which regular medicines to take on the day, and what happens if your sugar drops. Ask for the answers in writing.
What if the operation is an emergency during the fast?
Urgent care comes first. Tell staff you are fasting, let them plan around it, and do not refuse treatment because of the fast.
Does the doctor or the scholar decide the fast before an operation?
They answer different questions. The doctor sets the medical plan for the operation, and a qualified scholar gives the religious ruling on the fast.
