General Surgery • Abdominal Symptoms & Emergency Assessment

Abdominal Pain

Also called: Stomach Pain • Tummy Pain • Abdominal or Belly Pain

Abdominal pain is a symptom, not a diagnosis. It may arise from the digestive system, gallbladder, pancreas, urinary tract, reproductive organs, blood vessels, abdominal wall—or occasionally the chest.

The location provides clues, but severity, timing, associated symptoms, examination and selected tests matter more than a pain map alone. Some serious conditions begin with mild or poorly localised discomfort.

Some abdominal pain needs immediate hospital care

Seek Emergency Assessment If

  • Pain is sudden, severe, rapidly worsening, or the abdomen is very tender, hard or painful with movement.
  • There is collapse, confusion, cold sweating, severe weakness, breathlessness, chest pressure or a very fast pulse.
  • You vomit blood or dark material, pass black sticky stool, or have substantial bleeding from the bowel.
  • The abdomen is increasingly swollen with repeated vomiting and you cannot pass stool or gas.
  • Pain occurs with high fever, jaundice, persistent vomiting, very little urine or severe dehydration.
  • You are or could be pregnant and develop significant pain, vaginal bleeding, shoulder-tip pain, dizziness or fainting.
  • Abdominal pain is accompanied by sudden testicular pain, a painful irreducible groin lump or a cold, pale limb.
  • A baby, child, older adult or immunocompromised person is unusually drowsy, distressed, refusing fluids or rapidly becoming unwell.

Do not wait for an outpatient scan when these features are present. Emergency teams first assess circulation, breathing, internal bleeding, perforation, obstruction, severe infection and other time-critical causes.

“Stomach Pain” Does Not Always Come From the Stomach

The abdomen contains the stomach, bowel, liver, gallbladder, pancreas, spleen, kidneys, ureters, bladder, major blood vessels and reproductive organs. The abdominal wall, lower lungs, heart, spine and nerves can also refer pain into this area.

This is why one symptom can lead to very different investigations. The same condition can also present differently between people, and pain may move as an illness evolves.

What Does the Location Suggest?

LocationPossible sourcesImportant caution
Right upper abdomenGallbladder, liver, upper bowel, abdominal wall or lower chest.Pain with jaundice, fever or persistent vomiting needs prompt assessment.
Upper middleStomach, duodenum, pancreas, gallbladder, heart or major vessels.Heart or vascular emergencies can resemble indigestion.
Left upper abdomenStomach, spleen, pancreas, bowel, kidney, ribs or lower lung.Recent injury raises concern for splenic or rib-related problems.
Right lower abdomenAppendix, bowel, urinary tract, groin or a right ovary and tube when present.Appendicitis may begin near the centre before moving right.
Left lower abdomenColon, urinary tract, groin or a left ovary and tube when present.Age, bowel change, fever and pregnancy possibility alter the pathway.
Central / around the navelSmall bowel, early appendicitis, pancreas or a major blood vessel.Severe pain with few early examination findings can still be serious.
Flank or sideKidney, ureter, muscles, ribs, bowel or referred spinal pain.Urine symptoms do not prove the urinary tract is the cause.
GeneralisedWidespread bowel illness, obstruction, inflammation of the abdominal lining, metabolic or systemic disease.Increasing tenderness, distension or illness requires urgent review.

A location chart narrows possibilities but cannot diagnose the cause. Pregnancy, previous operations, age and anatomy can shift the expected position of organs and pain.

How the Pain Behaves Matters

Sudden onset

Abrupt severe pain raises concern for perforation, bleeding, torsion, vascular disease or obstruction.

Progressive pain

Pain that steadily localises or intensifies may reflect evolving inflammation or infection.

Colicky pain

Waves of pain can occur when a hollow organ contracts against a blockage.

Movement-related pain

Pain worsened by coughing, walking or bumps may indicate irritation inside the abdomen or an abdominal-wall cause.

Meal relationship

Timing after meals, prolonged pain or food avoidance can guide—but not confirm—the source.

Recurrent episodes

Repeated similar attacks need investigation even when symptoms settle between episodes.

Associated Symptoms Help Narrow the Cause

Associated featureQuestions it raisesWhy it matters
VomitingHow often, what colour, and is there abdominal swelling or inability to pass gas?May indicate obstruction, inflammation, infection or another systemic illness.
Bowel changeDiarrhoea, constipation, blood, black stool, mucus or altered stool calibre?Pattern and duration guide urgency and bowel investigation.
Urinary symptomsBurning, frequency, blood, reduced urine or pain radiating to the groin?Suggests urinary involvement but still requires clinical correlation.
Fever or chillsIs there localised pain, jaundice, wound, urinary change or systemic illness?Can signal infection or inflammation requiring prompt assessment.
JaundiceYellow eyes, dark urine, pale stool, fever or itching?May indicate obstruction or disease affecting the liver and bile ducts.
Menstrual or pregnancy contextLast period, pregnancy possibility, bleeding, discharge or one-sided pelvic pain?Pregnancy-related and gynaecological emergencies must be excluded.
Chest or breathing symptomsPressure, breathlessness, cough, pain on breathing or sweating?Heart and lung conditions can present as upper abdominal pain.

Common Categories of Abdominal Pain

CategoryExamplesTypical next question
Stomach and upper bowelInflammation, ulcer disease, outlet problems or perforation.Is there bleeding, persistent vomiting, weight loss or sudden severe pain?
Small and large bowelInfection, inflammation, appendicitis, diverticular disease, obstruction or tumour.Are stool, gas, distension, fever or localised tenderness changing?
Gallbladder and bile ductsGallstones, gallbladder inflammation or bile-duct obstruction.Is pain prolonged under the right ribs, with fever or jaundice?
PancreasAcute or chronic pancreatic inflammation and related complications.Is upper pain severe, persistent or radiating to the back?
Urinary tractStone, infection, blockage or bladder disease.Are there urine changes, fever, reduced output or groin radiation?
Reproductive organsPregnancy-related problems, ovarian or uterine disease and pelvic infection.Could pregnancy be present, and is there bleeding or one-sided pelvic pain?
Hernia and abdominal wallGroin or abdominal-wall hernia, muscle injury, nerve pain or scar-related problem.Is there a lump, skin change, vomiting or pain with movement?
Vascular or referred painAortic disease, reduced bowel blood supply, heart, lung or spinal causes.Does the pain seem disproportionate, sudden or associated with collapse or chest symptoms?

How Is Abdominal Pain Assessed?

  1. Check stabilityTemperature, pulse, blood pressure, breathing, hydration, consciousness and circulation are assessed first.
  2. Build a precise timelineOnset, location, movement, severity, triggers, previous episodes and associated symptoms are recorded.
  3. Review important contextAge, pregnancy possibility, previous operations, hernias, illnesses, travel, injury and recent tests affect the differential diagnosis.
  4. Examine the abdomenThe clinician looks for distension, scars, lumps and movement, then assesses tenderness, guarding, bowel sounds and masses.
  5. Check beyond the abdomenChest, back, groins, circulation and—when clinically necessary—pelvic, rectal or genital findings may change the diagnosis.
  6. Choose targeted testsLaboratory and imaging studies answer the leading clinical question rather than following one universal “abdominal pain panel.”
  7. Reassess over timeObservation and repeat examination may reveal a pattern that was not clear at the first assessment.

What Tests Might Be Needed?

TestWhat it can contributeImportant limitation
Blood testsInflammation, anaemia, dehydration, organ function, bile-duct or pancreatic patterns.Normal early results do not exclude every urgent surgical condition.
Urine testBlood, infection clues, concentration and other abnormalities.Urine findings can be incidental or occur with nearby inflammation.
Pregnancy testChanges imaging and the urgent differential diagnosis when pregnancy is possible.Timing and clinical symptoms still matter.
Stool testingSelected persistent diarrhoeal, bleeding or inflammatory presentations.It is not required for every episode of abdominal pain.
Heart or chest assessmentChecks non-abdominal causes of upper pain when symptoms or risk indicate.A normal abdominal scan cannot exclude heart or lung disease.

Ultrasound, X-ray, CT or MRI?

ImagingCommon roleWhat patients should know
UltrasoundGallbladder, bile ducts, liver, urinary tract, pelvis, pregnancy, fluid and selected appendix or bowel questions.It avoids radiation, but bowel gas, body habitus and deep structures can limit the view.
Plain X-raySelected obstruction, perforation, chest or foreign-body questions.A normal X-ray does not rule out appendicitis, gallbladder disease or many other causes.
CTBroad evaluation of non-localised pain, obstruction, perforation, inflammation, abscess, trauma and vascular disease.Radiation and contrast considerations are balanced against urgency and diagnostic value.
MRISelected bile-duct, pelvic, pregnancy, liver, bowel or problem-solving pathways.It takes longer and is not the first study for every unstable emergency.
No immediate imagingA stable patient with a clear low-risk clinical pattern may be observed or reviewed.Worsening, persistent or changing symptoms require reassessment.

The “best scan” depends on the leading diagnosis, age, pregnancy status, examination and local resources. More imaging is not automatically safer or more accurate.

When Is a Surgical Review Important?

  • Suspected appendicitis, gallbladder inflammation, perforation, bowel obstruction or reduced bowel blood supply.
  • A painful hernia that cannot be reduced, especially with vomiting, abdominal swelling or skin colour change.
  • An intra-abdominal abscess, uncontrolled bleeding or an illness requiring drainage or removal of diseased tissue.
  • Persistent focal tenderness, guarding or deterioration despite initially inconclusive tests.
  • A diagnosis where observation versus an operation depends on repeated examination and imaging.

A surgical assessment does not mean an operation is inevitable. It determines whether observation, further investigation, a procedure, an operation or referral provides the safest path.

Children, Older Adults and Pregnancy

GroupWhy presentation differsImportant approach
Babies and childrenThey may show irritability, drawing up the legs, poor feeding, vomiting, lethargy or refusal to move rather than localised pain.Clinical reassessment and radiation-conscious imaging are particularly important.
Older adultsSerious disease can cause modest pain, fever or laboratory change.Lower thresholds for assessment are appropriate with frailty, falls, vascular risk or confusion.
PregnancyNormal anatomy shifts, and pregnancy-related and non-pregnancy causes overlap.Pregnancy status guides urgent differential diagnosis and imaging selection.
Immunocompromised patientsInflammatory signs may be reduced despite significant infection or perforation.New persistent pain or illness warrants early clinical review.
After abdominal surgeryAdhesions, hernia, infection and procedure-specific complications enter the differential.Operation type, date and records are important to the assessing team.

What Happens If the First Tests Are Inconclusive?

Early abdominal disease may not declare itself immediately. If the patient is stable, the safest approach may include observation, repeat examination, laboratory trends, specialist review or different imaging based on how the pattern evolves.

  • Improvement does not erase the need to explain recurrent or unexplained episodes.
  • One normal test does not override worsening symptoms or new warning signs.
  • An incidental scan finding may be unrelated to the current pain and should not distract from the clinical question.
  • Discharge advice should identify exactly which changes require immediate return and when planned review will occur.

Common Examination and Scan Terms

TermPlain-language meaningWhy it matters
GuardingAbdominal muscles tighten during examination.Can be voluntary from fear or involuntary from internal irritation.
Rebound / peritonismPain and findings suggesting irritation of the abdominal lining.Raises concern for a surgical or inflammatory process.
Free airGas outside the bowel where it should not normally be.May indicate perforation and usually requires urgent surgical correlation.
Free fluidFluid within the abdominal or pelvic cavity.Small amounts can be normal in context; amount, density and symptoms determine significance.
Fat strandingInflamed-looking fat around an organ on CT.Helps localise inflammation but is not a diagnosis by itself.
Dilated bowel / transition pointExpanded bowel with a possible level where contents stop progressing.Supports obstruction and helps identify the site and cause.
Wall thickeningAn organ or bowel wall appears thicker than expected.Can reflect contraction, inflammation, reduced blood flow or tumour depending on context.
CollectionA localised pocket of fluid that may represent pus, blood or another material.Contents, location and clinical condition determine whether sampling or drainage is needed.
AppendicolithA small calcified deposit within the appendix.It can support appendicitis in the right clinical setting but does not diagnose it alone.
Incidental findingAn unexpected abnormality not necessarily related to the pain.It needs proportionate follow-up without replacing assessment of the presenting symptom.

Common Myths About Abdominal Pain

Myth “Severe disease always causes severe pain.”
Fact Older, pregnant or immunocompromised patients can have serious illness with subtle symptoms.
Myth “Right-sided pain always means appendicitis.”
Fact Bowel, urinary, gallbladder, groin and reproductive causes can overlap.
Myth “A normal blood test rules out surgery.”
Fact Important conditions can have normal or mildly altered early laboratory results.
Myth “Ultrasound can see every cause.”
Fact It is excellent for selected questions but cannot fully assess every bowel, vascular or deep abdominal problem.
Myth “A surgical review means I need surgery.”
Fact Surgeons also determine when observation, investigation or non-operative care is safer.
Myth “Recurring pain is harmless because it settles.”
Fact Recurrent gallstone, obstruction, inflammatory, urinary and other patterns still require diagnosis.

Frequently Asked Questions

Is abdominal pain the same as stomach pain?

Not exactly. “Stomach pain” is often used for any abdominal discomfort, but the true source may be the bowel, urinary tract, gallbladder, pancreas, reproductive organs, abdominal wall, chest or blood vessels.

Can the location identify the cause?

It narrows the possibilities but cannot confirm a diagnosis. Timing, movement, associated symptoms, examination and tests are equally important.

Why did the pain move?

Some conditions begin with poorly localised visceral pain and later irritate a specific part of the abdominal lining. A changing location can therefore be diagnostically important.

When is abdominal pain an emergency?

Sudden severe pain, collapse, a rigid or very tender abdomen, major bleeding, repeated vomiting with obstruction symptoms, pregnancy-related warning signs or chest and breathing symptoms require emergency assessment.

Can appendicitis start without right-sided pain?

Yes. It may begin centrally, remain atypical or occur in a different position. The complete clinical pattern and reassessment matter.

Can gallstones cause pain without jaundice?

Yes. Jaundice suggests bile-duct obstruction but is not required for gallbladder or gallstone-related pain.

Can kidney problems feel like abdominal pain?

Yes. Kidney and ureter problems can cause flank, lower abdominal or groin pain. Urine symptoms may be present or absent.

Why might I need a pregnancy test?

When pregnancy is biologically possible, the result changes urgent diagnoses and helps select the safest imaging pathway—even when pregnancy is not expected.

Will I always need a scan?

No. A clear low-risk clinical pattern may be managed with observation or review, while urgent or uncertain presentations need targeted imaging.

Is ultrasound better than CT?

Neither is universally better. Ultrasound is preferred for several biliary, pelvic, pregnancy and paediatric questions; CT gives a broader view for many adult emergencies.

Can blood tests be normal in appendicitis?

Yes, particularly early. Laboratory results support the clinical assessment but cannot safely rule out every urgent cause alone.

What does “no acute abnormality” on a scan mean?

No urgent structural cause was identified on that study. It does not mean the pain is imaginary or exclude every early, functional or non-abdominal condition.

Why am I being examined again?

Abdominal findings can evolve. Repeat examination may reveal localisation, guarding, distension or improvement that was not present initially.

Does a surgeon always operate?

No. Surgical review helps decide among observation, further tests, a procedure, an operation or referral according to the diagnosis and risk.

What information should I bring?

Bring previous operation details, scan and laboratory reports, current prescriptions, allergy information and a clear timeline of pain, vomiting, bowel, urine, menstrual or pregnancy-related symptoms.

A Note From Our Doctors

The information on this page is intended to help you understand your condition. It should not be considered a diagnosis or a substitute for a consultation with a qualified medical professional.

Every patient is unique. The same symptom can have different causes in different individuals, and the most appropriate investigations and treatment depend on your medical history, examination findings, age, existing medical conditions and test results.

At SR Speciality Hospital, we believe in treating the whole patient—not just a symptom, scan or laboratory report. Every treatment plan is individualised after careful medical evaluation.

General Surgery Consultation

Is abdominal pain persistent, recurring or becoming more localised?

Bring previous scan and laboratory reports, operation records and a current prescription list. Explain exactly when the pain began and any vomiting, bowel, urine, bleeding, jaundice, menstrual or pregnancy-related symptoms.
