What are the causes of acute abdominal pain?

The causes of acute abdominal pain are diverse, mainly including: 1. Acute inflammation of intra-abdominal organs: such as acute gastritis, acute enteritis, and acute pancreatitis, which can cause severe abdominal pain. 2. Obstruction or distention of hollow organs: intestinal obstruction, intussusception, biliary calculi, and urinary calculi are also common causes of acute abdominal pain. 3. Organ torsion and rupture: such as intestinal volvulus, gastrointestinal perforation, ovarian torsion, and liver rupture, which are emergencies requiring prompt treatment. 4. Vascular occlusion: vascular problems such as ischemic bowel disease and dissecting abdominal aortic aneurysm can also lead to acute abdominal pain. 5. Abdominal wall diseases and thoracic diseases: abdominal wall contusions, abscesses, or thoracic diseases such as myocardial infarction may also cause referred abdominal pain. 6. Systemic diseases: such as abdominal-type allergic purpura and diabetic acidosis, which may manifest as acute abdominal pain.
