In short
- Sudden severe tummy pain, a rigid very tender tummy, vomiting blood, black or bloody stools, or pain with high fever or fainting is a 999/A&E emergency — go now, do not book a private appointment.
- Once you are stable, the assessment finds urgent causes and guides the next step, but the exact diagnosis is not always clear in one visit.
- Blood and urine tests and often a scan are arranged the same day; some scans and specialist tests take longer.
- Private same-day assessment can be quicker, but for a possible surgical emergency the NHS emergency pathway (999, A&E) is the safest and fastest route.

What is an abdominal pain assessment?
If you have sudden, severe tummy pain that will not ease, a tummy that is hard and very tender to touch, pain with vomiting blood or passing black, tarry or bloody stools, or pain with a high fever, fainting or signs of serious infection, call 999 or go to A&E now. These can point to a surgical emergency or serious internal problem and should not wait for a private appointment.
An abdominal pain assessment is what happens once that emergency danger has been excluded. It is a careful, step-by-step look at why your tummy hurts, used for people who are stable — for example, pain that has settled, comes and goes, or has been building over days without the danger signs above.
The assessment is usually done by an acute physician or a general physician, with a surgeon, gynaecologist or gastroenterologist involved where needed. They take your story, examine your tummy, and arrange blood and urine tests and often a scan.
The tummy contains many organs, so be realistic about what one visit can do. The assessment is good at picking up causes that need urgent treatment and at guiding the next step, but the exact diagnosis is not always clear straight away, and some pain needs review over time or further tests.
Types, options & approaches
There may be different ways to do this. The right approach depends on the clinical question and your circumstances.
Calling 999 / A&E vs booking a private abdominal pain appointment
| Situation | 999 / A&E | Private same-day assessment |
|---|---|---|
| Sudden severe pain, rigid very tender tummy | Yes — straight away | No — do not delay |
| Vomiting blood, or black or bloody stools | Yes | No |
| Pain with high fever, fainting or feeling very unwell | Yes | No |
| Mild or moderate pain over days, otherwise well | Use NHS 111 if unsure (in Northern Ireland, your GP out-of-hours or Phone First service) | Reasonable for a stable work-up |
Do not drive yourself to A&E if you are very unwell — ask someone to drive you or call 999.
Preparing for your test
- First, rule out an emergency: sudden severe pain, a rigid tummy, vomiting blood, black or bloody stools, or pain with high fever or fainting means 999 or A&E now, not an appointment.
- If you are stable, note when the pain started, where it is, what it feels like, what makes it better or worse, and whether it has moved.
- Note other symptoms: vomiting, diarrhoea or constipation, fever, blood in vomit or stool, urine changes, and (for women) your last period.
- Bring a full list of your medicines, including painkillers, anti-inflammatories and blood thinners, and any allergies.
- Mention recent travel, new foods, alcohol intake, and any previous tummy operations or known conditions such as gallstones.
- Do not eat or drink before coming if you have been told you might need a scan or possible procedure, and check the clinic's instructions.
- Arrange someone to bring you and take you home if you feel unwell.
What happens
The clinician first checks you are safe, looking for signs of a surgical emergency or serious illness. If any are present, you move straight to emergency care rather than a routine work-up.
If you are stable, they take a detailed history and examine your tummy, pressing gently in different areas to find where it is tender. They may check your temperature, pulse and blood pressure. You will usually have blood tests and a urine test, and women of childbearing age will usually have a pregnancy test.
Depending on the picture, you may have an ultrasound or a CT scan. An ultrasound is often used first for the gallbladder, kidneys or pelvis; a CT scan gives more detail when the cause is unclear or a serious problem is suspected. The clinician explains what each test is for.
Before you leave, you should be told the likely cause or the plan to find it, what the results mean, what treatment you need, and what to do if the pain gets worse.
Is this test right for me?
A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.
May not be suitable if…
- Anyone with signs of a surgical emergency — sudden severe pain, a rigid tummy, bleeding, or pain with high fever or collapse — needs 999 or A&E, not a routine assessment.
- People who are very unwell, dehydrated or feverish, who need emergency assessment first.
- Settings without quick access to blood tests, scans, surgical opinion and a clear escalation route, as serious causes can be missed.
- Someone expecting a definite diagnosis in one visit for pain that may need review over time.
Delay or rearrange if…
- You currently have severe or worsening pain — this is an emergency; go to A&E rather than waiting.
- You are vomiting persistently, cannot keep fluids down, or are feverish and rapidly getting worse.
- A pregnancy test or medicine list is missing in a situation where it changes decisions.
- You cannot arrange safe transport or rapid access back to care if symptoms worsen.
Alternatives to discuss
- 999 and A&E for any possible surgical emergency or severe pain — the safest and fastest route.
- NHS acute medical or surgical assessment unit for stable but concerning pain, via your GP or NHS 111 (in Northern Ireland, via your GP out-of-hours or Phone First service).
- For urgent but not life-threatening advice when you are unsure whether symptoms need same-day care, use NHS 111 in England, Scotland or Wales. Northern Ireland does not have a region-wide 111 service, so contact your GP out-of-hours service or your HSC Trust's Phone First service instead. If the situation is life-threatening, call 999 or go to A&E.
- GP review for mild, longstanding or recurring pain to plan investigation.
Before you decide
Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.
What matters most to me?
Think about symptoms, daily life, work, caring responsibilities, sport, fertility, travel, appearance and anxiety — the right choice depends on your priorities, not just the medical facts.
What are all my options?
Ask about waiting, monitoring, medicines, rehabilitation, a smaller or larger procedure, a different test, NHS referral, or a second opinion where that would help.
What would make me pause?
Active infection, pregnancy, unstable medical problems, smoking, medicines that increase bleeding, poor support at home, or feeling pressured are all reasons to slow down and get tailored advice.
What happens if I do nothing today?
For some problems, waiting is safe; for others, delay can make treatment harder. A good consultation should explain the trade-off in plain English.
Benefits
- Quickly identifies causes that need urgent treatment, such as appendicitis, a blockage, a leak or a serious infection
- Rules out a pregnancy-related cause, including an ectopic pregnancy, in women of childbearing age
- Points you to the right next step, whether that is a surgeon, a gastroenterologist, antibiotics or simple measures
- Can reassure you when the cause is less serious, such as constipation, a urine infection or indigestion
- Gives a clear plan and safety-net advice for what to do if things change
Risks & complications
- Mild bruising or discomfort from blood tests
- Discomfort during the tummy examination
- Waiting around for tests and results
- Needing to come back for further tests if the cause is not clear in one visit
- A first set of tests that does not explain the pain, so uncertainty remains
- Incidental findings on scans that then need checking
- A reaction to the dye (contrast) used in some CT scans
- Radiation exposure from CT, weighed against the benefit
- A serious cause being hard to detect early, so symptoms must be re-checked if they change
- A significant allergic reaction to contrast dye
The tummy contains many organs, so the exact cause is not always clear in one visit, and an early normal set of tests does not rule out everything. The biggest danger is delaying emergency care for a surgical problem. A scan is not always needed, and CT involves radiation, so it is used when the benefit justifies it. Ask what the likely cause is, what is still uncertain, and exactly what to do if the pain worsens.
Published figures to discuss
There is no single reliable figure for the cause of abdominal pain, because it depends on age, sex, where the pain is and how it behaves. Many cases settle or have a simple cause; a minority need urgent surgery. Early tests and scans can be normal even when a problem is developing, and scans can reveal incidental findings, so doctors use examination, re-examination and safety-net advice rather than relying on one result. The aim is to identify dangerous causes safely, not to give a fixed success rate.
| Figure | Reported range | How to interpret it | Source / confidence |
|---|---|---|---|
| Surgical emergency missed | Red-flag dependent | Appendicitis, perforation, obstruction, ectopic pregnancy, testicular torsion and aortic aneurysm can all present with abdominal pain. | NHS — Stomach achenhs.ukSource-linked context |
| Early blood tests or examination falsely reassuring | Recognised | Inflammatory markers, fever and tenderness can be absent early, especially in older or immunosuppressed people. | Guide sourcesClinical context |
| Pregnancy-related emergency missed | Must be excluded where relevant | A pregnancy test is essential in people who could be pregnant because ectopic pregnancy can be life-threatening. | Guide sourcesClinical context |
| Imaging needed despite uncertain diagnosis | Common | Ultrasound, CT or surgical/gynaecology review may be needed when symptoms and tests do not line up. | Guide sourcesClinical context |
These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.
What happens afterwards
There is no physical recovery from the assessment itself. What matters afterwards is understanding the cause or the plan to find it, following any treatment, and knowing the danger signs that mean you should seek emergency help again.
- Some tenderness after the tummy examination
- Mild bruising where blood was taken
- Pain that eases once treatment is started
- Some uncertainty if more tests are needed, with a clear follow-up plan
Aftercare
- Take any medicines, such as antibiotics or painkillers, exactly as prescribed and ask what each is for.
- Follow up on any scans, endoscopy or specialist reviews that were arranged.
- Stick to any advice on eating and drinking, and stay hydrated unless told otherwise.
- Keep a note of how the pain changes, including any new symptoms, to share at follow-up.
- Know the danger signs that mean you should call 999 or go to A&E, and do not delay.
- Make sure you know who to contact, and how, if symptoms change before your next appointment.
- Do not assume normal first tests mean future severe pain can be ignored — treat it as an emergency.
- A clear note of where the pain is and how it started
- Notes on other symptoms (vomiting, bowels, fever, bleeding, urine, periods)
- A full list of your medicines and allergies
- Details of recent travel, alcohol and any previous tummy operations
- Someone to bring you and take you home
- Whether you may need to fast for a scan or procedure, checked with the clinic
- Questions written down and a way to record your result and plan
⚠ Get urgent help if…
- Sudden, severe tummy pain that does not ease — call 999 or go to A&E
- A tummy that is hard, swollen and very painful to touch — seek emergency help
- Vomiting blood, or vomit that looks like ground coffee — call 999
- Black, tarry or bloody stools — seek urgent help
- Pain with a high fever, shivering or feeling very unwell — possible serious infection, seek urgent help
- Pain with fainting, dizziness or a racing heart — call 999
- In women, severe one-sided lower tummy pain with a missed period or possible pregnancy — seek emergency help (possible ectopic pregnancy)
- Pain that keeps getting worse after you were sent home — seek urgent advice
Who to contact: your clinician, clinic or test provider first (keep their number to hand). For urgent advice when you can't reach them, call NHS 111. In an emergency, call 999.
General guidance — it doesn't replace the specific advice your specialist gives you.
Results & realistic expectations
A good result is a clear cause and a plan, or at least a confident decision that nothing dangerous needs treating today and a safe plan to follow up. Many causes are treatable or settle on their own — for example constipation, gastritis, a urine infection, gallstones or a viral illness.
The limits matter. The tummy has many organs, and an early normal set of tests does not rule out everything; some conditions, such as early appendicitis, can be hard to confirm at first. This is why doctors examine you carefully, sometimes re-examine after a few hours, and give clear advice about coming back. A normal result does not mean future severe pain can be ignored.
The result reflects what was found at the time. If your pain returns, changes or worsens, it needs assessing again on its own merits — an earlier normal result does not protect you. Where an ongoing cause such as gallstones or reflux is found, it may need its own treatment plan over time.
Related tests, treatments or support
An abdominal pain work-up often combines a careful examination with blood and urine tests, a pregnancy test where relevant, and a scan (ultrasound or CT). Depending on the cause, an endoscopy or a specialist opinion from a surgeon, gynaecologist or gastroenterologist may follow. Your clinician should explain why each is chosen.
Follow-up & long-term care
How you get your results depends on the setting. You should leave knowing which tests are still outstanding, when and how you will get them, who will act on them, and what to do if your pain worsens. If you were referred to a surgeon or other specialist, check the appointment is booked.
- Take any prescribed treatment as directed and complete antibiotic courses if given.
- Follow any dietary advice for the cause found, such as gallstones or reflux.
- Attend any follow-up scans, endoscopy or specialist appointments.
- Keep a record of any further episodes of pain to discuss.
Repeat, follow-on and what comes next
- An inconclusive first assessment may need further tests, such as a CT scan or endoscopy, over the following days.
- Re-examining you after a few hours is normal practice for conditions that declare themselves over time, such as early appendicitis.
- If pain returns or worsens, the whole picture should be re-assessed rather than relying on an earlier normal result.
Ask what happens if the result is unclear or needs repeating, and what is included if further tests or follow-up are needed.
What good aftercare looks like
- Clear written advice on the symptoms that mean you should call 999 or go to A&E.
- A named way to get outstanding results and to be seen again if needed.
- A treatment plan and any specialist referral, shared with your GP.
- Honest communication that the diagnosis may need review, and how that will happen.
What affects the cost
Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:
- How urgently you are seen and whether the assessment is in a same-day unit or an outpatient clinic
- Which clinician assesses you (acute physician, general physician, surgeon, gynaecologist or gastroenterologist)
- How many blood and urine tests are needed, including a pregnancy test
- Whether you need an ultrasound or a CT scan, and whether contrast dye is used
- Whether a specialist reports the scans on the same day
- Any follow-up appointment, endoscopy, further tests or onward referral
- The clinician's assessment fee and which specialty they are from
- The cost of blood and urine tests, including a pregnancy test
- The cost of any ultrasound or CT scan, and reporting
- Whether contrast dye and its reporting are included
- What happens, and what it costs, if you need further tests, endoscopy or admission
- Any follow-up appointment and how results are communicated
- The cancellation policy and what happens if a complication occurs
On the NHS? Abdominal pain is assessed on the NHS through 999, A&E and acute medical and surgical units when clinically indicated; private same-day assessment is mainly used for speed, choice or a second opinion in stable patients, never as a substitute for emergency care.
You're entitled to your total cost in writing — including reports, follow-up and what happens if the result is inconclusive — before you decide.
Consent traps and marketing red flags
These are not small details. They are often where patients lose choice, time to reflect, or realistic expectations.
Consent traps
- A pregnancy-related cause not being considered in a woman of childbearing age.
- Being reassured by normal first tests without clear advice that the diagnosis may evolve.
- No written safety-net advice on when to return or call 999.
- Being steered into a private booking when the pain actually needs emergency care.
- Not being told about radiation or contrast dye before a CT scan.
Marketing red flags
- Any service that assesses severe tummy pain instead of telling you to go to A&E for danger signs.
- Claims that one scan rules out every cause of abdominal pain.
- Whole-body or abdominal screening packages sold on fear without explaining limitations and false positives.
- Same-day private appointments promoted as a substitute for emergency care.
Choosing a specialist safely
- Check the specialist is on the GMC Specialist Register for this area.
- Make sure they work at a CQC-registered service, and look for membership of the relevant Royal College or professional body.
- You're entitled to time to consider and to have your questions answered before you agree — the specialist who looks after you should explain it, not a salesperson.
- Be wary of pressure: time-limited offers or deposits taken before you've had time to think are red flags, not bargains.
- You're entitled to your total cost in writing — including any follow-up — before you decide.
Questions to ask your medical professional
Take this to your consultation. A good specialist will welcome every one of these.
- What do you think is causing my pain, and how sure can you be today?
- Have you ruled out the dangerous causes, including (for women) a pregnancy-related cause?
- Do I need a scan, and will it be an ultrasound or a CT — and why?
- What exactly should I do, and who should I call, if the pain gets worse?
- Which results are still outstanding, and how and when will I get them?
- Do I need to see a surgeon or another specialist?
- Are you on the GMC Specialist Register for this area, and which Royal College or professional body are you a member of?
- Will you be the specialist who carries out my test, and who looks after me afterwards?
- What are the risks for someone like me, and how often do your own patients have a problem or need it repeated or redone?
- What does a realistic result look like — and what can this test not achieve?
- What are my options, including waiting, doing nothing for now, or choosing a different approach?
- Can I have written information, results and aftercare instructions in a format I can use, including any accessibility or communication support I need?
- What is the total cost in writing, including any follow-ups, and how much time do I have to decide?
