🤕 Abdominal Pain Guide
Understanding different types of abdominal pain and what they may indicate
Last reviewed: February 2026
📖 Understanding Abdominal Pain
Abdominal pain is one of the most common reasons for visiting a doctor. The abdomen contains many organs - stomach, intestines, liver, gallbladder, pancreas, spleen, kidneys, appendix, and reproductive organs - and pain can originate from any of them.
Types of Abdominal Pain
- Visceral pain: Dull, poorly localized pain from internal organs (stretching, distension)
- Parietal/somatic pain: Sharp, well-localized pain from irritation of the abdominal wall lining
- Referred pain: Pain felt in a different location from its source (e.g., gallbladder pain felt in shoulder)
Pain Characteristics to Note
- Location: Where exactly does it hurt?
- Character: Sharp, dull, crampy, burning, stabbing?
- Severity: Scale of 1-10
- Onset: Sudden or gradual?
- Duration: How long has it lasted?
- Radiation: Does it spread elsewhere?
- Timing: Constant or intermittent? Related to meals?
- Aggravating factors: What makes it worse?
- Relieving factors: What makes it better?
- Associated symptoms: Nausea, vomiting, fever, bowel changes?
📍 Pain Location Guide
The location of abdominal pain provides important clues about the underlying cause.
| Location | Common Causes |
|---|---|
| Right Upper Quadrant (RUQ) | Gallbladder disease, hepatitis, liver problems, right kidney stone, pneumonia (referred) |
| Left Upper Quadrant (LUQ) | Spleen problems, gastritis, peptic ulcer, pancreatitis, left kidney stone, heart attack (referred) |
| Right Lower Quadrant (RLQ) | Appendicitis, ovarian cyst, ectopic pregnancy, Crohn's disease, kidney stone |
| Left Lower Quadrant (LLQ) | Diverticulitis, constipation, ovarian cyst, ectopic pregnancy, kidney stone |
| Epigastric (Upper Middle) | GERD, gastritis, peptic ulcer, pancreatitis, heart attack |
| Periumbilical (Around Navel) | Early appendicitis, small bowel obstruction, gastroenteritis, aortic aneurysm |
| Suprapubic (Lower Middle) | Bladder infection, pelvic inflammatory disease, menstrual cramps |
| Diffuse/Generalized | Gastroenteritis, IBS, peritonitis, bowel obstruction |
🚨 Emergency Warning Signs
- Sudden, severe abdominal pain
- Pain with rigid, board-like abdomen
- Vomiting blood or black/tarry stools
- Fever with severe pain
- Fainting or signs of shock (rapid pulse, cold sweaty skin, confusion)
- Unable to pass stool or gas with distended abdomen
- Pain following abdominal trauma
- Chest pain that may radiate to abdomen
- Pregnancy with abdominal pain and/or bleeding
- Pain that wakes you from sleep
Conditions Requiring Urgent Evaluation
- Appendicitis: Pain starting around navel, moving to right lower quadrant, with fever, nausea
- Cholecystitis: Right upper quadrant pain after fatty meals, fever
- Pancreatitis: Severe epigastric pain radiating to back
- Bowel obstruction: Crampy pain, vomiting, distension, no passing gas
- Perforated ulcer: Sudden severe pain, rigid abdomen
- Ectopic pregnancy: Lower abdominal pain, missed period, vaginal bleeding
- Kidney stones: Severe flank pain radiating to groin, unable to get comfortable
📋 Common Causes by Category
Gastrointestinal
Burning or gnawing pain in upper abdomen. May worsen or improve with eating depending on location. Associated with H. pylori infection or NSAID use. May have nausea, bloating.
Chronic crampy abdominal pain associated with bowel movements. Usually relieved by defecation. Accompanied by bloating, diarrhea, constipation, or alternating. No weight loss, fever, or blood.
Crampy, diffuse or left-sided pain. Associated with infrequent bowel movements, hard stools, straining. Often relieved by bowel movement. Common in all ages.
Crampy pain throughout abdomen with diarrhea and/or vomiting. Often with fever. Usually viral, self-limited over 1-3 days. May follow sick contact or suspect food.
Chronic pain, bloody diarrhea, weight loss. Crohn's may cause right lower quadrant pain. Ulcerative colitis causes left-sided or diffuse pain with bloody diarrhea.
Hepatobiliary
Episodic right upper quadrant pain, often after fatty meals. May radiate to right shoulder or back. Pain builds, plateaus, and slowly decreases over 30 min to several hours. Nausea common.
Similar to biliary colic but pain is more severe, prolonged (over 6 hours), and accompanied by fever. Requires urgent evaluation and often surgery.
Urological
Severe, colicky pain in flank radiating to groin. Patients cannot find comfortable position. Often with blood in urine, nausea, vomiting. Comes in waves.
Lower abdominal/suprapubic discomfort with urinary frequency, urgency, burning. If fever and flank pain, may indicate kidney infection (pyelonephritis).
Gynecological (Women)
- Menstrual cramps (dysmenorrhea): Lower abdominal cramping with periods
- Mittelschmerz: Mid-cycle ovulation pain
- Ovarian cyst: One-sided lower abdominal pain
- Endometriosis: Chronic pelvic pain, worse with periods
- Pelvic inflammatory disease: Lower abdominal pain, discharge, fever
- Ectopic pregnancy: EMERGENCY - lower abdominal pain with missed period
🔍 Diagnosis
History & Physical Exam
The doctor will ask detailed questions about your pain and examine your abdomen. Key findings include:
- Point tenderness (where exactly it hurts when pressed)
- Guarding (involuntary muscle tightening)
- Rebound tenderness (pain when pressure released - suggests peritonitis)
- Bowel sounds (absent, hyperactive, normal)
- Masses or organ enlargement
Common Tests
- Blood tests: CBC, metabolic panel, liver enzymes, amylase/lipase, pregnancy test
- Urinalysis: For kidney/bladder issues
- Stool tests: If diarrhea present
- Ultrasound: Excellent for gallbladder, kidneys, ovaries, appendix
- CT scan: Most comprehensive for acute abdominal pain
- X-ray: For obstruction, perforation (free air)
- Endoscopy: For upper GI symptoms
- Colonoscopy: For lower GI symptoms or screening
💊 Management Approaches
General Measures
- Rest: Lie in a comfortable position
- Heat: Warm compress may help crampy pain (not if inflammation suspected)
- Stay hydrated: Especially with vomiting or diarrhea
- Avoid eating: Until diagnosis is clear for acute severe pain
Medications
- Antispasmodics: For crampy/colicky pain (dicyclomine, hyoscine)
- Antacids/PPIs: For acid-related pain
- Pain relievers: Acetaminophen safer than NSAIDs for GI pain
- Anti-nausea: Ondansetron, promethazine if needed
- Antibiotics: Only if bacterial infection diagnosed
Treatment Depends on Cause
- Appendicitis: Surgery (appendectomy)
- Gallstones: Surgery (cholecystectomy) if symptomatic
- Kidney stones: Fluids, pain control, sometimes procedures
- Ulcers: PPIs, H. pylori treatment if present
- Diverticulitis: Antibiotics, bowel rest
- Bowel obstruction: May need surgery
- IBS: Diet, lifestyle, medications for symptoms
🏠 When to Manage at Home
You may be able to manage at home with self-care for:
- Mild pain without concerning features
- Obvious cause (constipation, gas, menstrual cramps)
- Short duration (a few hours)
- No fever, vomiting, blood, or severe symptoms
- Improving with time
Home Care Tips
- Rest
- Clear fluids if nauseated
- Bland diet when appetite returns
- Over-the-counter antacids for heartburn/indigestion
- Fiber and fluids for constipation
- Heat pad for menstrual cramps
- Track symptoms - if worsening, seek care
❓ Frequently Asked Questions
Serious signs include: severe or sudden-onset pain, pain that wakes you from sleep, fever, vomiting blood, black stools, rigid abdomen, fainting, or inability to pass gas/stool. Pain that is getting progressively worse rather than better should also be evaluated promptly.
Post-meal pain can result from: eating too fast, overeating, food intolerance (lactose, gluten), gallbladder disease (especially after fatty foods), peptic ulcer, gastroparesis, or functional dyspepsia. Keeping a food diary can help identify patterns.
Yes, stress significantly affects the gut through the gut-brain connection. Stress can cause or worsen symptoms in IBS, functional dyspepsia, and other conditions. Stress management is often part of treatment for chronic abdominal pain.
It depends on the cause. Acetaminophen (paracetamol) is generally safer for abdominal pain than NSAIDs (ibuprofen, aspirin), which can irritate the stomach. Avoid masking severe pain before diagnosis, as this can delay identifying serious conditions. If pain is severe, seek medical care rather than self-medicating.
