Overview

The causes of abdominal pain vary with the distribution of the pain. The distribution can be determined by various methods, such as into either abdominal quadrants or nine sections.

Causes

Causes Based upon Location

Life Threatening Causes

Life-threatening causes include conditions that may result in death or permanent disability within the next 24 hours if left untreated.

2

Common Causes

Injury to the Abdominal wall
- Abdominal cutaneous nerve entrapment syndrome
- Mesenteric traction syndrome
- Muscle trauma
- Muscular infection
Autoimmune:
- sarcoidosis
- vasculitis
Diarrhea
Digestive:
- lactose intolerance
- celiac sprue
Distention of visceral surfaces such as the hepatic or renal capsule
Endometriosis
Functional pain:
- Irritable bowel syndrome (affecting up to 20% of the population, IBS is the most common cause of recurrent, intermittent abdominal pain)
Inflammation of bowel wall:
- Crohn's disease
- Diverticulitis
- Gastroenteritis
- Microscopic colitis
- Ulcerative colitis
Mechanical obstruction of hollow viscera such as the small intestine, the appendix associated with appendicitis, the large intestine (e.g. by intussusception), the biliary tree (e.g. by gallstones), or the ureter (e.g. by urinary calculi)
Meningitis
Metabolic disturbance:
- Adrenal insufficiency
- Black widow spider bite
- C1-esterase inhibitor deficiency
- Diabetic ketoacidosis
- Lead poisoning,
- Porphyria
- Uremia
Neurogenic pain:
- Herpes zoster
- Lyme disease (Lyme radiculitis or Bannwarth syndrome)
- Tabes dorsalis
Parietal peritoneal inflammation
- Due to infection: inflamed or suppurative appendix in appendicitis, pelvic inflammatory disease
- Due to chemical irritation: perforated gastric or peptic ulcer; pancreatitis, Mittelschmerz, ruptured ectopic pregnancy
- Miscellaneous (Familial Mediterranean fever)
Pelvic inflammatory disease
Post-surgical adhesions
Referred pain from:
- Genitals (testicular torsion)
- Coronary occlusion)
- The spine (radiculitis secondary to arthritis)
- The thorax (pneumonia
Reproductive organs (in women):
- Ectopic pregnancy
- Mittelschmerz
- Torsion of the ovary
Vascular disturbances (leading to ischemia):
- Embolism
- Left renal vein entrapment
- Sickle cell anemia
- Superior mesenteric artery syndrome (Nutcracker syndrome)
- Thrombosis
- Torsional occlusion (volvulus)
- Vascular rupture
