Abdominal Pain but a Normal CT Scan: What Happens Next?

Yes. Abdominal pain with a normal CT scan is common, because CT mainly looks for structural problems such as blockages, stones, abscesses, masses or signs of appendicitis. Many causes of stomach pain, including irritable bowel syndrome, indigestion and some problems of the stomach lining, may not show up on CT.

This guide is for adults who have had an abdominal CT reported as normal and still have pain. It helps you understand the result and prepare questions. It cannot find a cause, judge how urgent your pain is or replace an assessment by a clinician.

A normal scan does not protect against a new or changing problem. The NHS advises calling emergency services or going to an emergency department if stomach pain starts suddenly and is severe, or comes with any of the symptoms listed below. Do not drive yourself.

MedlinePlus also lists sudden sharp belly pain, a rigid or hard belly, chest, neck or shoulder pain, recent injury to the abdomen, pregnancy or possible pregnancy, and current cancer treatment as reasons for emergency care. Ask for an urgent appointment through local services if pain suddenly gets much worse, or comes with blood in your stools, vomiting or diarrhoea lasting more than a few days, or unusual vaginal bleeding. MedlinePlus also advises contacting a clinician about pain with fever.

• Vomiting blood, or vomit that is green or looks like coffee grounds
• A lot of blood from the bottom, or black, sticky stools
• Being unable to pass urine, stools or wind at all
• A rash or spots that do not fade when pressed
• Difficulty breathing

An abdominal CT uses X-rays to make cross-sectional pictures of the belly. MedlinePlus lists problems it can help find, including appendicitis, kidney stones, hernias, infections and abscesses, and masses. Contrast dye, given by mouth or through a vein, can make some areas easier to see.

CT pictures structures. It does not directly measure how the gut moves or how sensitive the nerves of the gut are, and it is not the main test for looking at the inner lining of the stomach. NIDDK describes upper endoscopy, a camera passed through the mouth, as the test that examines that lining and can detect gastritis and peptic ulcers.

A scan also reflects one moment. If the pain was mild on the day, or a problem was at an early stage, the picture may differ from what happens later. Check the full radiology report, not only a portal label saying ‘normal’, and ask whether contrast was used and which areas were included.

MedlinePlus notes that many causes of abdominal pain are not serious, such as constipation, food intolerance and irritable bowel syndrome (IBS). It also says the severity of pain does not reliably reflect how serious the cause is, which is why a clinician looks at the whole picture rather than the scan alone.

Some common conditions are diagnosed mainly from the pattern of symptoms after other causes have been considered. NIDDK describes IBS as abdominal pain linked to bowel movements or to changes in how often stools come or how they look, usually over months. Functional dyspepsia may be considered for upper abdominal pain, burning or early fullness when tests find no other cause.

These are possibilities to discuss, not explanations to assume. Bloating, diarrhoea, reflux and period-related pain each have their own guides and next steps, linked at the end of this page.

Location is one of the first things a clinician asks about. MedlinePlus lists questions such as where the pain is, whether it stays in one spot or spreads to the back, groin or legs, and whether it is constant or comes and goes. Right side or left side abdominal pain with a normal CT can lead to different follow-up questions.

Pain can be felt away from the organ causing it, so location narrows the possibilities rather than settling them. For lower abdominal pain, gynaecological causes such as endometriosis or ovarian cysts, and urinary causes such as kidney stones or infection, are on MedlinePlus's list of possible causes. Describe the exact place, ideally by pointing on a body diagram, rather than labelling the organ yourself.

Further testing depends on your symptoms, examination and history. Options MedlinePlus lists for abdominal pain include blood, urine and stool tests, abdominal ultrasound, upper endoscopy, colonoscopy and an ECG. Not everyone needs more tests; for IBS, NIDDK notes that doctors often do not use tests to make the diagnosis.

Ask what each proposed test would add to the CT result. NIDDK lists features that suggest something other than IBS, such as anaemia, rectal bleeding, black or tarry stools and weight loss. Mention any of these clearly, because they can change the plan.

Bring the CT report, recent blood results, your medicine and supplement list, and a short symptom record covering timing, meals, bowel habits and periods if relevant. These questions are a conversation aid, not a request for more scans.

• Which causes did the CT make less likely, and which does it not assess well?
• Was contrast used, and did the scan cover the area where my pain is?
• Does my symptom pattern fit a diagnosis such as IBS or functional dyspepsia, or is something still unexplained?
• Would endoscopy, ultrasound, stool tests or blood tests add anything in my case, and why?
• Which changes in my symptoms should make me seek care sooner, and who should I contact?
• When should we review the pain again if nothing changes?

On SameCase, patients and verified doctors share de-identified cases. Reading how others with abdominal pain and a normal CT described their symptoms, what they were asked and which next steps were discussed can help you organise your own notes and questions.

Another person's case cannot diagnose you, and their tests or treatment may not suit you. Use what you read to prepare for your appointment, and take any concerns to the clinician who knows your history.
