How are causes of abdominal pain diagnosed?

- Whether the abdominal pain started after consuming certain foods
- Whether sleeping in certain positions aggravates the pain
- Additional symptoms such as bloody stools or vomiting
Your doctor will take your medical history, including past surgeries, and examine your abdomen for tenderness or color changes.
To rule out serious causes of abdominal pain and confirm a diagnosis, your doctor may order one or more tests such as:
- Blood tests to test for infection, red blood cell count, liver and kidney function, and electrolytes
- Stool tests
- Urine tests
- Abdominal ultrasound
- Abdominal computed tomography scan
- Endoscopy (use of a flexible, tube-like camera to visualize the inside of the organs)
- Biopsy (surgical removal of a small piece of an organ to check for cancerous cells)
