Abdominal pain (or stomach ache)


Abdominal pain (or stomach ache) can be one of the symptoms associated with transient disorders or serious disease. Making a definitive diagnosis of the cause of abdominal pain can be difficult, because many diseases can result in this symptom. Abdominal pain is a common problem. Most frequently the cause is benign and/or self-limited, but more serious causes may require urgent intervention.

When a physician assesses a patient to determine the etiology and subsequent treatment for abdominal pain the patients history of the presenting complaint and physical examination should derive a diagnosis in over 90% of cases.

It is important also for a physician to remember that abdominal pain can be caused by problems outside the abdomen, especially heart attacks and pneumonias which can occasionally present as abdominal pain.

Investigations that would aid diagnosis include

* Blood tests including full blood count, electrolytes, urea, creatinine, liver function tests, pregnancy test and lipase.
* Urinalysis
* Imaging including erect chest X-ray and plain films of the abdomen
* An electrocardiograph to rule out a heart attack which can occasionally present as abdominal pain

If diagnosis remains unclear after history, examination and basic investigations as above then more advanced investigations may reveal a diagnosis. These as such would include

* Computed Tomography of the abdomen/pelvis
* Abdominal or pelvic ultrasound
* Endoscopy and colonoscopy (not used for diagnosing acute pain)
