Abdominal pain or stomach pain is a common symptom associated with both temporary, non-serious disorders and more serious conditions. Common causes include gastroenteritis and irritable bowel syndrome. In a third of cases the exact cause is unclear. About 10% of people have a more serious underlying condition such as appendicitis or diverticulitis.〔 Determining the cause can be difficult, because many diseases can cause this symptom. ==Differential diagnosis== The most frequent cause of abdominal pain is gastroenteritis (13%), irritable bowel syndrome (8%), urinary tract problems (5%), inflammation of the stomach (5%) and constipation (5%). About 30% of cases the cause is not determined. About 10% of cases have a more serious cause including gallbladder or pancreas problems (4%), diverticulitis (3%), appendicitis (2%) and cancer (1%). More common in those who are older, mesenteric ischemia and abdominal aortic aneurysms are other serious causes. A more extensive list includes the following: * Gastrointestinal * * GI tract * * * Inflammatory: gastroenteritis, appendicitis, gastritis, esophagitis, diverticulitis, Crohn's disease, ulcerative colitis, microscopic colitis * * * Obstruction: hernia, intussusception, volvulus, post-surgical adhesions, tumours, superior mesenteric artery syndrome, severe constipation, hemorrhoids * * * Vascular: embolism, thrombosis, hemorrhage, sickle cell disease, abdominal angina, blood vessel compression (such as celiac artery compression syndrome), Postural orthostatic tachycardia syndrome * * * digestive: peptic ulcer, lactose intolerance, coeliac disease, food allergies * * Glands * * * Bile system * * * * Inflammatory: cholecystitis, cholangitis * * * * Obstruction: cholelithiasis, tumours * * * Liver * * * * Inflammatory: hepatitis, liver abscess * * * Pancreatic * * * * Inflammatory: pancreatitis * Renal and urological * * Inflammation: pyelonephritis, bladder infection * * Obstruction: kidney stones, urolithiasis, Urinary retention, tumours * * Vascular: left renal vein entrapment * Gynaecological or obstetric * * Inflammatory: pelvic inflammatory disease * * Mechanical: ovarian torsion * * Endocrinological: menstruation, Mittelschmerz * * Tumors: endometriosis, fibroids, ovarian cyst, ovarian cancer * * Pregnancy: ruptured ectopic pregnancy, threatened abortion * Abdominal wall * * muscle strain or trauma * * muscular infection * * neurogenic pain: herpes zoster, radiculitis in Lyme disease, abdominal cutaneous nerve entrapment syndrome (ACNES), tabes dorsalis * Referred pain * * from the thorax: pneumonia, pulmonary embolism, ischemic heart disease, pericarditis * * from the spine: radiculitis * * from the genitals: testicular torsion * Metabolic disturbance * * uremia, diabetic ketoacidosis, porphyria, C1-esterase inhibitor deficiency, adrenal insufficiency, lead poisoning, black widow spider bite, narcotic withdrawal * Blood vessels * * aortic dissection, abdominal aortic aneurysm * Immune system * * sarcoidosis * * vasculitis * * familial Mediterranean fever * Idiopathic * * irritable bowel syndrome (affecting up to 20% of the population, IBS is the most common cause of recurrent, intermittent abdominal pain)
