Abdominal pain is pain that is felt in the abdomen. The abdomen is an anatomical area that is bounded by the lower margin of the ribs above, the pelvic bone (pubic ramus) below, and the flanks on each side
- For Evaluation of Pain, Abdomen is divided into four quadrants:
- right upper quadrant
- right lower quadrant
- left upper quadrant
- left lower quadrant
- and three central areas:
- epigastric
- periumbilical
- suprapubic
Causes of pain in each Quadrant are
Epigastric pain

Types of abdominal pain
Visceral
– originates in abdominal organs covered by peritoneum
Colic
–crampy pain
Parietal
– from irritation of parietal peritoneum
Referred
-Produced by pathology in one location felt at another location
- pain from hollow viscera
- crampy/paroxismal
- often poorly localized
- related to peristalsis
- patient writhing on exam table
- pain from peritoneal irritation
- steady/constant
- often localized
- patient lies still with knees up
Types and mechanisms
Types and mechanisms
- The pain associated with inflammation of the parietalperitoneum is steady and aching, and worsened by changes in the tension of peritoneum caused by pressure or positional change. It is often accompanied by tension of the abdominal muscles contracting to relieve such tension.
- The pain associated with obstruction of a hollow viscus is often intermittent or “colicky“
- The pain associated with abdominal vascular disturbances (thrombosisor embolism) can be sudden or gradual in onset, and can be severe or mild. Pain associated with the rupture of an abdominal aortic aneurysm may radiate to the back, flank, or genitals.
- Pain that is felt in the abdomen may be “referred” from elsewhere (g., a disease process in the chest may cause pain in the abdomen), and abdominal processes can cause radiated pain elsewhere (e.g., gall bladderpain—in cholecystitis or cholelithiasis—is often referred to the shoulder).

Aggravating and relieving factors
The history of abdominal pain is a critical element in the evaluation. Note the following:
Understanding Abdominal Pain: When to Suspect Surgical Causes
Mode of onset, progression, character, and severity of abdominal pain can help differentiate between surgical and nonsurgical causes. Sudden, severe, or explosive pain that’s continuous, progressive, and lasts more than 6 hours generally points to a surgical etiology. In contrast, gradual onset, mild to moderate intensity, intermittent pain that resolves or improves within 6 hours usually signals a nonsurgical condition.
Pain from hollow, tubular structures—like the ureter, intestines, biliary ducts, or fallopian tubes—can be continuous or colicky. The narrower the structure involved, the more intense the pain. If you or someone you know is dealing with this kind of persistent, intense discomfort, it may be time to consult the Best Laparoscopic Surgeon in Gachibowli for accurate diagnosis and timely intervention.
Activity at pain onset also offers clues. Pain that begins during rest or sleep often suggests a surgical problem. If pain follows physical exertion or eating, it tends to be nonsurgical.
Pain location and migration matter. The farther from the umbilicus the pain localizes, the more likely it’s surgical.
Epigastric pain = issues with the foregut (stomach, duodenum, biliary tract, pancreas, spleen)
Periumbilical pain = midgut problems (jejunum, ileum, appendix, proximal colon)
Hypogastric pain = hindgut or pelvic organs (distal colon, reproductive organs, bladder)
Pain that shifts location, like in appendicitis—starting periumbilically and moving to the right lower quadrant—suggests that inflammation has reached the parietal peritoneum and requires urgent evaluation.
Associated symptoms can provide further clarity. In surgical conditions, pain typically comes before nausea, vomiting, and anorexia. In nonsurgical conditions, those symptoms often precede the pain. Vomiting, especially in obese patients, is a red flag. Anorexia in an athlete—especially an obese one—is not common and should be taken seriously.
Fever is common, but fever with chills more often points to infections outside the surgical abdomen—like in the urinary or respiratory tracts.
Constipation can occur in both types, but obstipation (no gas or stool) strongly indicates a surgical issue. On the other hand, diarrhea with cramping typically suggests a nonsurgical cause like gastroenteritis or IBD.
Always ask what aggravates the pain first. Movement, coughing, or walking—especially downstairs—can irritate the peritoneum, suggesting surgical concern. Relief with posture change points to musculoskeletal pain. Relief after a bowel movement suggests a nonsurgical gastrointestinal cause.
Menstrual history and reproductive status are key in women. Abdominal pain is more frequent in women due to a broader range of potential genitourinary causes. Among sexually active women, surgical issues like ectopic pregnancy or ovarian torsion must be ruled out. Pain following an abnormal period may signal ectopic pregnancy. Bilateral pain with fever but without nausea or vomiting soon after a period often indicates pelvic inflammatory disease.
In men, abdominal pain may stem from seminal vesiculitis, prostatitis, or urethritis. However, men with abdominal pain have a higher chance of surgical disease, making prompt evaluation critical.
Certain medications and supplements—like NSAIDs, erythromycin, potassium, and salt tablets—can irritate the stomach and cause pain.
History matters: previous episodes, similar symptoms in family or peers, known food intolerances, allergies, sudden training or diet changes, or recent travel to high-risk areas suggest nonsurgical causes.
In any scenario where a surgical cause is suspected, it’s crucial to consult the Best Laparoscopic Surgeon in Gachibowli to ensure fast, minimally invasive care and avoid complications.
Work-up
Physical examination
Inspection
Inspection is always an important first step in any physical examination. Look at the abdominal contour and note any asymmetry. Record the location of scars, rashes, or other lesions.
Position – patient should be supine and the bed or examination table should be flat. The patient’s hands should remain at his/her sides with his/her head resting on a pillow. If the head is flexed, the abdominal musculature becomes tensed and the examination made more difficult. Allowing the patient to bend her knees so that the soles of her feet rest on the table will also relax the abdomen.
Lighting – adjusted so that it is ideal.
Draping – patient should be exposed from the pubic symphysis below to the costal margin above – in women to just below the breasts. Some surgeons would describe an abdominal examination being from nipples to knees.
Auscultation
Unlike other regions of the body, auscultation comes before percussion and palpation (the sounds may change after manipulation). Record bowel sounds as being present, increased, decreased, or absent
Percussion
Dullness
Resonance
Obliteration of liver dullness
Palpation
Begin with light palpation. At this point you are mostly looking for areas of tenderness. The most sensitive indicator of tenderness is the patient’s facial expression.
Look for Guarding -rebound tenderness and Rigidity
Rectal exam : Look for
Empty balloned rectum in Obstruction
Tender anterior wall in Pelvic Peritonotis
Mucus /blood on finger in Intususception
Pelvic exam Look For
Tenderness of fornices in Salpingitis
Tender movements of cervix in Pregnancy
Fullness of douglas pouch in Pelvic Abscess

Differentiating Common Nonmusculoskeletal Sources of Abdominal Pain | |
Condition | Typical Signs and Symptoms |
Appendicitis, acute | Constant pain, progressively more severe; begins in periumbilical region, moves to right lower quadrant; nausea, vomiting, and anorexia follow pain; low-grade fever; patient appears ill |
Cholecystitis, acute | Constant pain in right upper quadrant, onset often postprandial; nausea and vomiting; tenderness in right upper quadrant and right shoulder; splinting on right side |
Perforated peptic ulcer | Sudden onset of pain in midepigastrium that spreads and is aggravated by movement; patient appears acutely ill and is reluctant to move; rigid abdomen; grunting respiration; bowel sounds absent |
Ectopic pregnancy | Pain sudden, severe, and persistent, generally following a missed or abnormal period, typically epigastric; often associated with hypotension and tachycardia |
Ovarian cyst | Pain constant with sharp, sudden onset; usually in ipsilateral hypogastrium; may have nausea and vomiting following the pain |
Pelvic inflammatory disease | Pain at end of or shortly after normal menstrual period; bilateral lower quadrant pain aggravated by cervical manipulation; anorexia, nausea, and vomiting rare; possible cervical discharge; fever |
Urinary calculus | Pain location changes with movement of stone, may radiate to testicle, groin of involved side; pain very severe; patient cannot get comfortable |
